Suppose Company A produces packages of throat lozenges that are normally distributed with a mean of 38.2 individual lozenges and a standard deviation of 1.7 lozenges.
Company B produces packages of throat lozenges that are normally distributed with a mean of 36.9 individual lozenges and a standard deviation of 2.4 lozenges.
Select from the drop-down menus to correctly complete the statement.
CHOICES ARE COMPANY A AND COMPANY B
Answer: B, A, B
Step-by-step explanation:
Let's find the z-score for both companies using the formula: [tex]z=\dfrac{x-\mu}{\sigma}[/tex]
Company A: [tex]z=\dfrac{43-38.2}{1.7}=\large\boxed{2.8}[/tex]
Company B: [tex]z=\dfrac{43-36.9}{2.4}=\large\boxed{2.5}[/tex]
The z-score from Company B is closer to 0 than the z-score of Company A so it it more likely that a package of 43 lozenges is produced by Company B
Since the z-score from Company A is closer to zero than the z-score of Company B, the company that produced a package with 43 lozenges in it is most likely Company A.
To find which company is more likely to produce a package with 43 lozenges, we'll first calculate the z-scores for each company using the formula:
[tex]\[ z = \frac{x - \mu}{\sigma} \][/tex]
Where:
- [tex]\( x \)[/tex] is the number of lozenges in the package (43)
- [tex]\( \mu \)[/tex] is the mean number of lozenges in the package for each company
- [tex]\( \sigma \)[/tex] is the standard deviation of the number of lozenges in the package for each company
For Company A:
[tex]\[ z_A = \frac{43 - 38.2}{1.7} = \frac{4.8}{1.7} \approx 2.82 \][/tex]
For Company B:
[tex]\[ z_B = \frac{43 - 36.9}{2.4} = \frac{6.1}{2.4} \approx 2.54 \][/tex]
Since the z-score for Company A (2.82) is higher than the z-score for Company B (2.54), it indicates that the value of 43 lozenges is relatively further away from the mean for Company A compared to Company B.
Thus, Company A is more likely to produce a package with 43 lozenges.
The correct question is:
Suppose Company A produces packages of throat lozenges that are normally distributed with a mean of 38.2 individual lozenges and a standard deviation of 1.7 lozenges.
Company B produces packages of throat lozenges that are normally distributed with a mean of 36.9 individual lozenges and a standard deviation of 2.4 lozenges.
Select from the drop-down menus to correctly complete the statement.
Since the [tex]$z$[/tex]-score from [tex]$\square$[/tex] is closer to zero than the [tex]$z$[/tex]-score of [tex]$\square$[/tex] , the company that produced a package with 43 lozenges in it is most likely [tex]$\square$[/tex] .

The coordinates of point P on a coordinate grid are (?5, ?6). Point P is reflected across the y-axis to obtain point Q and across the x-axis to obtain point R. What are the coordinates of points Q and R? 1. Q(5, 6) and R(?5, ?6) 2. Q(?5, ?6) and R(5, 6) 3. Q(?5, 6) and R(5, ?6) 4. Q(5, ?6) and R(?5, 6)
Answer:
(5, −6) and R(−5, 6)
Step-by-step explanation:
Answer:
4. Q(5, -6) and R(-5, 6)
Step-by-step explanation:
In the coordinates of point P which is (-5,-6) when you reflect it on the Y axis that means that the Y would be the same but the X will change signs, thats why the point Q is (5.-6) and to reflect it on the X axis the X remains the same but the Y would change the sign this is why point R will be (-5,6).
So point Q is (5,-6) and point R is (-5,6).
The equations for two distinct lines are given below.
y = –6x + 20
y = 5x – 13
What is the x-coordinate of the point of intersection of the two lines?
A.-2
B.2
C.-3
D.3
answer for this question is (d) 3
To find the x-coordinate of the point of intersection of the two given lines, set the equations equal and solve for x, revealing that the x-coordinate is 3 (D).
The question involves finding the x-coordinate of the point of intersection of two lines represented by the equations y = –6x + 20 and y = 5x – 13. To find the point of intersection, we can set the two equations equal to each other because at the point of intersection, the y-values (and x-values) for both equations will be the same.
Setting the equations equal to each other:
–6x + 20 = 5x – 13
Adding 6x to both sides and adding 13 to both sides gives:
33 = 11x
Dividing both sides by 11:
x = 3
Therefore, the x-coordinate of the point of intersection of the two lines is 3, which corresponds to answer choice D.

Answer:
x = 55.6
Step-by-step explanation:
In this triangle, the hypotenuse is the unknownj. The sine function relates the hypotenuse, the angle and the side opposite the angle:
sin Ф = opp / hyp
Here, sin 20° = 19 / x. This can be rearranged as x = 19 / sin 20°
This works out to x = 19 / 0.342, or 55.6.
x = 55.6

1. - sqrt3
2. -1/sqrt3
3. 1/sqrt3
4. sqrt3
ANSWER
[tex] -\sqrt{3}[/tex]
EXPLANATION
The given angle is 870°.
870°-360°-360°=150°
This means that:
870° is coterminal with 150°, hence its terminal side is in the second quadrant.
It makes an acute angle of 30° with the x-axis.
Note that cotangent is negative in the second quadrant,
Hence,
[tex] \cot(870 \degree) = \cot(150 \degree) = - \cot(30 \degree) = - \frac{1}{ \tan(30 \degree) } = - \sqrt{3} [/tex]

Answer:
[tex]|KL|=7\sqrt{2}[/tex]
Step-by-step explanation:
The given triangle is a right triangle.
The m<K=45 degrees.
This means the measure of <L is also 45 degrees.
This implies that;
|LM|=|KM|=7 units.
From the Pythagoras Theorem;
[tex]|KL|^2=|LM|^2+|KM|^2[/tex]
[tex]|KL|^2=7^2+7^2[/tex]
[tex]|KL|^2=2(7^2)[/tex]
[tex]|KL|=\sqrt{2(7^2)}[/tex]
[tex]|KL|=7\sqrt{2}[/tex]
Option C is correct.
The answer is:
The third option,
[tex]KL=7\sqrt{2}[/tex]
Why?Since we are working with a right triangle, we can use the following identity:
[tex]Sin(\alpha)=\frac{y}{hypothenuse}[/tex]
We are given:
[tex]\alpha =45\°\\LM=y=7[/tex]
[tex]hypothenuse=KL[/tex]
Then, substituting and solving we have:
[tex]Sin(45\°)=\frac{7}{hypothenuse}[/tex]
[tex]Hypothenuse=KL=\frac{y}{Sin(45\°)}=\frac{7}{\frac{\sqrt{2} }{2} } \\\\Hypothenuse=KL=7\sqrt{2}[/tex]
Hence, the answer is the third option,
[tex]KL=7\sqrt{2}[/tex]

Find the median and mean of this data set: 83, 27, 11, 78, 50, 33, 46.
Median:
Mean:
Range:
Answer:
Median: 46
Mean: about 46.9
Range: 72
Step-by-step explanation:
Median:
Put them in order
11 27 33 46 50 78 83
Then find the middle value which is 46.
Mean:
Add them all together then divide by the number of values
(11+27+33+46+50+70+83)/7
about 46.8571
Range:
Highest value-lowest value
83-11
72
To solve for the median, mean, and range of the given data set, we will follow these steps:
**Step 1: Organize the Data Set**
First, we must organize the data set in ascending order to calculate the median. The given data set is: 83, 27, 11, 78, 50, 33, 46.
Arranging the numbers, we get:
11, 27, 33, 46, 50, 78, 83
**Step 2: Find the Median**
The median is the middle value of a data set when it's ordered from least to greatest. Since there are seven numbers, the middle one will be the fourth value (since there are three numbers on each side of it).
So, the median is: 46
**Step 3: Calculate the Mean**
To calculate the mean (average), we sum all the numbers and then divide by how many numbers there are.
Mean = (Sum of all numbers) / (Number of numbers)
Sum = 11 + 27 + 33 + 46 + 50 + 78 + 83 = 328
Number of numbers = 7
Mean = 328 / 7 = 46.857 (approximately)
**Step 4: Find the Range**
The range is the difference between the highest and lowest values in the data set.
Minimum value = 11
Maximum value = 83
Range = Maximum value - Minimum value
Range = 83 - 11 = 72
**Summary:**
Median: 46
Mean: Approximately 46.857
Range: 72

Answer:
[tex]\$806.14[/tex]
Step-by-step explanation:
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
Part 1)
Find the interest rate r
we have
[tex]t=1\ years\\ P=\$575\\ r=?\\n=1\\A=\$615[/tex]
substitute in the formula above and solve for r
[tex]\$615=\$575(1+\frac{r}{1})^{1*1}[/tex]
[tex]\$615=\$575(1+r)[/tex]
[tex]r=(615/575)-1\\ \\ r=0.07[/tex]
The interest rate is 7%
Part 2)
we have
[tex]t=4\ years\\ P=\$615\\ r=0.07\\n=1\\A=?[/tex]
substitute in the formula
[tex]A=\$615(1+\frac{0.07}{1})^{1*4}[/tex]
[tex]A=\$615(1.07)^{4}=\$806.14[/tex]
in the 1980s, an average mortgage range was around 18.75%. how much less per month would a $125,000 30 year mortgage be today if the current rate were 5%?
Answer:
$1289.48
Step-by-step explanation:
A financial calculator tells you the payment with the higher interest rate is $1960.51, and that with the lower interest rate is $671.03. The difference in payment amounts is ...
$1960.51 -671.03 = $1289.48
Answer:
The current per month mortgages are $1289.54 less than the earlier per month mortgages.
Step-by-step explanation:
The EMI formula is = [tex]\frac{p\times r\times (1+r)^{n} }{(1+r)^{n}-1 }[/tex]
Here p = 125000
For case 1:
r = 18.75/12/100=0.015625
n = [tex]30\times12=360[/tex]
So, putting values in formula we get :
[tex]\frac{125000\times 0.015625\times (1+0.015625)^{360} }{(1+0.015625)^{360}-1 }[/tex]
= $1960.51
For case 2:
r = 5/12/100=0.004166
n = [tex]30\times12=360[/tex]
So, putting values in formula we get :
[tex]\frac{125000\times 0.004166\times (1+0.004166)^{360} }{(1+0.004166)^{360}-1 }[/tex]
= $670.97
Now we will find the difference between both EMI's
[tex]1960.51-670.97=1289.54[/tex] dollars.
Therefore, the current per month mortgages are $1289.54 less than the earlier per month mortgages.
Write the definite integral for the summation: the limit as n goes to infinity of the summation from k equals 1 to n of the product of the square of the quantity 1 plus k over n squared and 1 over n.

Answer:
Option C
Step-by-step explanation:
We are given that
[tex]\lim_{n\rightarrow\infty}\sum_{k=1}^{n}(1+\frac{k}{n})^2\times \frac{1}{n}[/tex]
We have to find the definite integral for the given summation.
We know that
[tex]\lim_{n\rightarrow \infty}\sum_{k=a}^{n}f(a+k\frac{b-a}{n})(\frac{b-a}{n}=\int_{a}^{b}f(x)dx[/tex]
Using the formula
a=1
[tex]\frac{b-a}{n}=\frac{b-1}{n}[/tex]
[tex]\frac{b-1}{n}=\frac{1}{n}[/tex]
[tex]b-1=1[/tex]
[tex]b=1+1=2[/tex]
[tex]\lim_{n\rightarrow\infty}\sum_{k=1}^{n}(1+\frac{k}{n})^2\times \frac{1}{n}=\int_{1}^{2}x^2 dx[/tex]
Option C is true.
Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x-3y=13 4x-y=-9
2x -3y = 13
4x -y = -9
Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.
4x -y = -9 x -3 = -12x + 3y = 27
Now add this to the first equation:
2x -12x = -10x
-3y +3y = 0
13 +27 = 40
Now you have :
-10x = 40
Divide each side by -10:
x = 40 / -10
x = -4
Now you have a value for x, replace that into the first equation and solve for y:
2(-4) - 3y = 13
-8 - 3y = 13
Add 8 to both sides:
-3y = 21
Divide both sides by -3:
y = 21/-3
y = -7
Now you have X = -4 and y = -7
(-4,-7)
Using the DMS method to describe an angle, one degree of angle measurement can be divided into how many minutes?
Answer:
1 degree = 60 minutes
Step-by-step explanation:
The DMS method is for Degree Minutes Seconds. That allows you to give a precise location the way it's most commonly used on paper maps. Today, with the electronic maps we mostly use the numeric version (34.234 degrees for example).
So, in the DMS method, one degree is basically like an hour on your clock. It can be divided into 60 minutes. Then, those minutes can be divided into 60 seconds. Just like an hour, a degree has 60 minutes and 3600 seconds.
Final answer:
One degree in the DMS method of angle measurement is divided into 60 minutes. To convert DMS to DD, like with 118 degrees 15 minutes, divide the minutes by 60 and add the result to the degrees, giving you 118.25.
Explanation:
In the DMS method of angle measurement, one degree is equivalent to 60 minutes of angle. This is similar to how an hour of time is divided into 60 minutes. To visualize this, if you consider a full circle being 360 degrees, each degree can be further subdivided into 60 smaller parts, each of these parts is known as a minute of angle.
For example, the conversion of 118 degrees 15 minutes to decimal degrees (DD) is a simple mathematical process. You would divide the minutes by 60 since there are 60 minutes in a degree, resulting in the equation 118 + 15/60, which equals 118.25 degrees. This conversion is an important skill in coordinate conversion activities, where positions are described in DMS format and need to be converted to DD for calculations.
Find the exact value.
tan240°
Answer:
1.732050808
Step-by-step explanation:
https : // www. desmos. com/ scientific
EDIT square root of 3
The exact value of tan240° is the same as tan60° because of the periodicity of the tangent function and the fact that 240° lies in the third quadrant of the unit circle. The value of tan60° is √3 or about 1.732.
To find the exact value of tan240°, we should recall that the tangent function is periodic with a period of 180°, meaning tan(θ) is the same as tan(θ + 180°). Also, in the unit circle, 240° lies in the third quadrant, where tangent values are positive because both sine and cosine are negative. Therefore, tan240° is the same as tan(240° - 180°), which is tan60°. The exact value of tan60° is √3) or approximately 1.732. This calculation leverages trigonometric principles and the geometric interpretation of angles on the unit circle, demonstrating how to derive accurate values for trigonometric functions in specific angular contexts.

Ramon wants to make a rectangular prism with 5 cubes. Can he do this? Explain. Draw cubes to show your answer.
Answer:
Place them in a line.
Step-by-step explanation:
Take the First cube and place it on the paper
Then place another cube behind that cube
Repeat with remaining cubes
Should end up with a line of cubes that create a rectangular prism.
Ramon cannot form a rectangular prism using exactly 5 cubes because a rectangular prism has 6 faces, which would each be formed by a cube. To create even the smallest possible rectangular prism, he would need at least 6 cubes.
Explanation:No, Ramon cannot make a rectangular prism using exactly 5 cubes. A rectangular prism is a three-dimensional figure with six faces that are rectangles. It would not be possible to form a rectangular prism using only 5 cubes because to form a rectangular prism you need at least 6 cubes.
Each cube would represent one face of the rectangular prism.
This is because a rectangular prism has 3 dimensions: length, width, and height. Even if you make the smallest possible rectangular prism, you would need a minimum of 6 cubes (1 cube length, 1 cube width, and 6 cubes high). If he has only 5 cubes, at least one dimension (length, width, or height) would be incomplete.

Answer:
A = 25√3 cm²
Step-by-step explanation:
View 5√3 cm as being the height of an equilateral triangle whose base is at the bottom of the purple figure. To find the area of one such triangle, we use the area-of-a-triangle formula A = (1/2)(b)(h).
opp
Using the sine function sin Ф = --------
hyp
we find the length of the hypotenuse, which is also the radius of the octagon, and because this is an equilateral triangle, is also the length of the base:
√3 5√3 cm
sin 60° = -------- = ------------- , which produces the value of hyp:
2 hyp
√3 5√3 cm
-------- = ------------- , which produces the value of hyp:
2 hyp
√3·hyp = 10√3, or hyp = 10 cm
Then the area of this one triangle is A = (1/2)(b)(h), or
A = (1/2) (10 cm)(5√3 cm) = 25√3 cm²

Avery invested $2,100 in an account paying an interest rate of 7 7/8% compounded continuously. Morgan invested $2,100 in an account paying an interest rate of 8 1/4 % compounded annually. After 12 years, how much more money would Morgan have in her account than Avery, to the nearest dollar?
Answer:
[tex]\$34[/tex]
Step-by-step explanation:
step 1
Avery
we know that
The formula to calculate continuously compounded interest is equal to
[tex]A=P(e)^{rt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
[tex]t=12\ years\\ P=\$2,100\\ r=7 7/8\%=7.875\%=0.07875[/tex]
substitute in the formula above
[tex]A=\$2,100(e)^{0.07875*12}=\$5,402.91[/tex]
step 2
Morgan
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
[tex]t=12\ years\\ P=\$2,100\\ r=8 1/4\%=8.25\%=0.0825\\n=1[/tex]
substitute in the formula above
[tex]A=\$2,100(1+\frac{0.0825}{1})^{1*12}=\$5,436.94[/tex]

Marisa earns $7.50 an hour working at Panera. She wants to earn at least $250 to purchase 4 concert tickets. The cost of each ticket is $75 plus a $12.95 convenience fee per ticket. Is $250 enough to cover the cost of 4 tickets? If not, how many more hours does she need to work to cover the difference? No, she would need to work an additional 14 hours to purchase 4 concert tickets. No, she would need to work an additional 34 hours to purchase 4 concert tickets. No, she would need to work an additional 47 hours to purchase 4 concert tickets. Yes, $250 is enough to purchase 4 concert tickets.
Answer:
Part 1) [tex]\$250[/tex] is not enough to cover the cost of 4 tickets
Part 2) She would need to work an additional 14 hours to purchase 4 concert tickets
therefore
No, she would need to work an additional 14 hours to purchase 4 concert tickets
Step-by-step explanation:
step 1
Find the cost of 4 tickets
[tex]4*(75+12.95)=\$351.80[/tex]
so
[tex]\$351.80> \$250[/tex]
therefore
[tex]\$250[/tex] is not enough to cover the cost of 4 tickets
step 2
Find the number of hours needed to work to cover the difference
The difference is equal to
[tex]\$351.80-\$250=\$101.80[/tex]
Let
x-----> the number of hours needed to work to cover the difference
The inequality that represent the situation is
[tex]7.50x \geq 101.50[/tex]
[tex]x \geq 101.50/7.50[/tex]
[tex]x \geq 13.5\ hours[/tex]
The minimum number of hours is 14
