Final answer:
The minimum is 6, the first quartile is 16, the median is 29, the third quartile is 54, the maximum is 93, and the interquartile range is 38.
Explanation:
To find the minimum, first quartile (Q1), median, third quartile (Q3), maximum, and interquartile range (IQR) of the given data set, we first need to organize the data in ascending order, which is already done. Then, we apply the appropriate statistical methods to determine each required value.
Minimum: The smallest number in the data set, which is 6.First Quartile (Q1): This is the median of the first half of the data set. With 13 numbers, the first half is the first 6 numbers. The median of 6, 13, 14, 18, 19, 29 is the average of 14 and 18, so Q1 is (14+18)/2 = 16.Median: The middle number when the data is in order. Since there are 13 numbers, the 7th number is the median, which is 29.Third Quartile (Q3): The median of the second half of the data set. The second half is the last 6 numbers. The median of 35, 44, 53, 55, 71, 84 is the average of 53 and 55, so Q3 is (53+55)/2 = 54.Maximum: The largest number in the data set, which is 93.Interquartile Range (IQR): The range between the first and third quartiles, which is Q3 - Q1, so the IQR is 54 - 16 = 38.please help! John-Mark recorded the stats for several baseball pitchers. He made a scatterplot showing the
number of games they played and the percentage they lost. Which line is the best fit for this
data?
y = 10x - 70
y = 10x + 70
y = -10x + 110
y = -10x - 110
Answer: Third Option
[tex]y = -10x + 110[/tex]
Step-by-step explanation:
The equation of a line in the pending intersection form has the following form:
[tex]y=mx +b[/tex]
Where m is the slope of the line and b is the intersection with the y axis.
Observe in the graph that the data form a decreasing line. Then the adjustment line must have a negative slope [tex]m <0[/tex].
The first and the second option have positive slopes, therefore we discard them.
Notice in the scatter diagram that the intersection of the line with the y-axis (x = 0) is above 90.
The line of the fourth option has a value of [tex]b = -110 <90[/tex].
Therefore the line that best fits the data is the third option
[tex]y = -10x + 110[/tex]
Note that the line has a slope [tex]m = -10[/tex] and a value of [tex]b> 90[/tex]

Tim throws a stick straight up in the air from the ground. The function h = –16t2 + 48t models the height, h, in feet, of the stick above the ground after t seconds. Which inequality can be used to find the interval of time in which the stick reaches a height of more than 8 feet?
The inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet is -[tex]16t^2 + 48t > 8[/tex]
To solve this inequality, let's rearrange it:
-[tex]16t^2 + 48t - 8 > 0[/tex]
Now, we have a quadratic inequality. To solve it, we'll first find the critical points by setting the expression equal to zero:
[tex]-16t^2 + 48t - 8 = 0[/tex]
Now, we'll use the quadratic formula to find the roots:
[tex]t = [ -b ± √(b^2 - 4ac) ] / (2a)[/tex]
Where a = -16, b = 48, and c = -8.
Plugging in these values, we get:
[tex]t = [ -48 ± √(48^2 - 4(-16)(-8)) ] / (2(-16))[/tex]
[tex]t = [ -48 ± √(2304 - 512) ] / (-32)[/tex]
[tex]t = [ -48 ± √(1792) ] / (-32)[/tex]
[tex]t ≈ [ -48 ± 42.35 ] / (-32)[/tex]
Now, we have two critical points:
t1 ≈ (-48 + 42.35) / (-32) ≈ 0.186
t2 ≈ (-48 - 42.35) / (-32) ≈ 2.814
Now, we'll test intervals between and outside these critical points to determine when the inequality is satisfied:
For t < 0.186: The quadratic term dominates, leading to a negative value.
For 0.186 < t < 2.814: The quadratic term dominates, leading to a positive value.
For t > 2.814: The linear term dominates, leading to a negative value.
So, the solution to the inequality is 0.186 < t < 2.814.
Thus, the stick reaches a height of more than 8 feet between approximately 0.186 seconds and 2.814 seconds.
Complete question:

Determine whether the sequence is arithmetic, geometric, both, or neither. 1, 4, 9, 16, 25, . . .
Answer:
neither
Step-by-step explanation:
First differences are 3, 5, 7, 9, and the differences of these (2nd differences) are constant at 2. The degree of the polynomial function describing the sequence is equal to the number of the differences that are constant. Here, that is 2nd differences, so the sequences is described by a 2nd-degree (quadratic) polynomial.
It is not linear (arithmetic) or exponential (first differences have a common ratio).

Janet can do a job in 3 hours while Garry can do the same job in 2 hours. If Janet works for an hour before Garry began helping her, how long will it take them to finish the job together?
Answer:
4/5 hour (48 minutes)
Step-by-step explanation:
Janet works at the rate of ...
(1 job)/(3 hours) = (1/3) job/hour
So, in 1 hour, she has worked 1/3 of the job, leaving 2/3 of the job remaining when Garry shows up.
Garry works at the rate of ...
(1 job)/(2 hours) = 1/2 job/hour
So, together they work at the rate of ...
(1/3 job/hour) + (1/2 job/hour) = (2/6 +3/6) job/hour = 5/6 job/hour
Then the time it takes to do the remaining 2/3 job is ...
(2/3 job)/(5/6 job/hour) = (2/3·6/5) hour = 4/5 hour
It will take 4/5 hour for them to finish the job together.
Answer: 4/5 of an hour or 48 minutes
Step-by-step explanation:
Janet's Rate : 1 job / 3 hours = 1/3 job/hour
In 1 hour, 1/3 of the job is already finished by her, so there is 2/3 of the job left.
Garry's Rate:
1 job / 2 hours = 1/2 job/hour
Janet an Garry's Rate:
1/3 job/hour + 1/2 job/hour = 2/6 +3/6 job/hour = 5/6 job/hour
Time to do remaining 2/3 of job:
2/3 job / 5/6 job/hour = 2/3 * 6/5 hour = 4/5 hour
Answer:
It will take 4/5 of an hour for them to finish the job together.

A sewer line slopes 1/4" per foot grade. Calculate the total fall in 30 feet.
The answer is:
The total fall in 30 feet will be 7.5 inches.
Why?To calculate the total fall in 30 feet, given the slope (decreasing rate for this case), we need to use the following equation:
[tex]TotalFall=\frac{\frac{1}{4} inch}{foot}*FeetAmount[/tex]
We are asked to calculate the total fall in 30 feet, so, substituting it into the equation, we have:
[tex]TotalFall=\frac{\frac{1}{4} inch}{foot}*30feet[/tex]
[tex]TotalFall=7.5inch[/tex]
Hence, we have that the total fall in 30 feet will be 7.5 inches.
Have a nice day!
Final answer:
To calculate the total fall in elevation for a sewer line with a 1/4" per foot grade over 30 feet, simply multiply 1/4" by 30, resulting in a total fall of 7.5 inches.
Explanation:
The student is asking how to calculate the total fall in elevation for a sewer line that has a consistent slope over a given distance. The slope given is 1/4" per foot of sewer line. To find the total fall over 30 feet, you need to multiply the slope per foot with the total distance.
Calculation:
Determine the slope per foot, which is 1/4".
Multiply this slope by the total distance, which is 30 feet.
1/4" x 30 = 7.5". This is the total fall in elevation over 30 feet.
The total fall in elevation for a sewer line over 30 feet, with a slope of 1/4" per foot, is 7.5 inches.

Answer:
A.-7
Step-by-step explanation:
If [tex]2x-3y=11[/tex] and [tex]3x+15=0[/tex]
To know the value of y we need to clear x in the equation [tex]3x+15=0[/tex] and the result replace it in [tex]2x-3y=11[/tex].
Then, let's clear x in the equation [tex]3x+15=0[/tex]
[tex]3x=-15\\x=-\frac{15}{3} =-5[/tex]
Substituting the value of x in the equation [tex]2x-3y=11[/tex]
[tex]2(-5)-3y=11\\-10-3y=11\\-3y=11+10\\y=\frac{11+10}{-3} \\y=\frac{21}{-3}\\ y=-7[/tex]

A spinner has 10 equally sized sections, 6 of which are gray and 4 of which are blue. The spinner
is spun twice. What is the probability that the first spin lands on blue and the second spin lands
en gray
Write your answer as a fraction in simplest form.
Answer:
6/25
Step-by-step explanation:
6/10 chance for grey.
4/10 chance for blue.
And = Multiplication
Or = Addition
6/10 times 4/10 = 24/100
24% chance or 6/25 chance it will land on grey and blue.
(Theoretical Probability)
The probability that the first spin lands on blue and the second spin lands on gray is 6/25.
The probability of the first spin landing on blue and the second spin landing on gray can be calculated as follows:
Probability of landing on blue on the first spin = 4/10 = 2/5
Probability of landing on gray on the second spin = 6/10 = 3/5
Multiply the probabilities of each spin: (2/5) * (3/5) = 6/25
Therefore, the probability that the first spin lands on blue and the second spin lands on gray is 6/25.

D. m<GCB + m<CBE = 180°
E. m<BEG + m<EGC = 230°
F. The sum of all exterior angles of BEGC is equal to 360°.
Answer:
The sum of all exterior angles of BEGC is equal to 360° ⇒ answer F only
Step-by-step explanation:
* Lets revise some facts about the quadrilateral
- Quadrilateral is a polygon of 4 sides
- The sum of measures of the interior angles of any quadrilateral is 360°
- The sum of measures of the exterior angles of any quadrilateral is 360°
* Lets solve the problem
- DEGC is a quadrilateral
∵ m∠BEG = (19x + 3)°
∵ m∠EGC = (m∠GCB + 4x)°
∵ The sum of the measures of its interior angles is 360°
∴ m∠BEG + m∠EGC + m∠GCB + m∠CBE = 360
∴ (19x + 3) + (m∠GCB + 4x) + m∠GCB + m∠CBE = 360 ⇒ add the like terms
∴ (19x + 4x) + (m∠GCB + m∠GCB) + m∠CBE + 3 = 360 ⇒ -3 from both sides
∴ 23x + 2m∠GCB + m∠CBE = 375
∵ The sum of measures of the exterior angles of any quadrilateral is 360°

Answer:
x=4
Step-by-step explanation:
Simplifying
4x + 16 + -1x = 22 + 6
Reorder the terms:
16 + 4x + -1x = 22 + 6
Combine like terms: 4x + -1x = 3x
16 + 3x = 22 + 6
Combine like terms: 22 + 6 = 28
16 + 3x = 28
Solving
16 + 3x = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + -16 + 3x = 28 + -16
Combine like terms: 16 + -16 = 0
0 + 3x = 28 + -16
3x = 28 + -16
Combine like terms: 28 + -16 = 12
3x = 12
Divide each side by '3'.
x = 4
Simplifying
x = 4
Hope this helps! And please correct me if I'm wrong so others can have the correct answer.
For this case we must solve the following equation:
[tex]4x + 16-x = 22 +6[/tex]
We add similar terms on both sides of equality:
[tex]3x + 16 = 28[/tex]
We subtract 16 from both sides of the equation:
[tex]3x = 28-16\\3x = 12[/tex]
We divide between 3 on both sides of the equation:

Please help me out with this
Answer:
10.8 ft
Step-by-step explanation:
The height from the base can be found from the formula for the volume. Fill in the given information and solve for the height.
V = (1/3)Bh = (1/3)s²·h
432 ft³ = (1/3)(12 ft)²·h . . . . . fill in side length and volume
h = 432 ft³/(48 ft²) = 9 ft . . . divide by the coefficient of h
The slant height is the hypotenuse of a right triangle with this height as one leg and half the side length as the other leg.
slant height = √((9 ft)² +(12 ft/2)²) = √(117 ft²) = 3√13 ft
slant height ≈ 18.817 ft ≈ 18.8 ft
