Answer:
Option 1 and 2 are correct.
Step-by-step explanation:
1. {x:x <-3 or >4}
Here the values of x can be less than -3 or the values of x can be greater than 4. Since 5 is greater than 4 so, 5 is included in the solution
2. {x:x ≥5}
Here the values of x can be greater than or equal to 5. So, 5 is included in the solution.
3. {x:x <5}
Here the values of x can be less than 5. So, 5 is not included in the solution
4. {x:0<x<4}
Here the value of x is greater than 0 but less than 4. So, 5 is not included in the solution
So, Option 1 and 2 are correct.
HELP PLEASE WILL GIVE BRAINLIEST TO WHOM CAN ANSWER CORRECTLY A lawn-care specialist chooses a random sample from the yard and determines the number of weeds in the sample. The results of the sample are shown in the table below.
look at attachment
Which explains whether or not this is a representative sample?
Yes, this is a representative sample because each type of weed is represented in the sample.
Yes, this is a representative sample because each type of weed is represented approximately the same number of times in the sample.
No, this is not a representative sample because each type of weed should be represented in proportion to the number of weeds actually present in the yard.
No, this is not a representative sample because each type of weed should be represented exactly the same number of times in the sample.
Answer: No, this is not a representative sample because each type of weed should be represented in proportion to the number of weeds actually present in the yard.
Step-by-step explanation:
A representative sample has to be in proportion, and the diagram shows that the greater part is not represented in proportion. Because it is not represented in proportion, it is not a representative sample.
Answer: C
Answer:
Letter C because the sample size is not in proportion to the rest of the weeds in the grass.

Sandra calculated the height of a cylinder that has a volume of 576(pie) cubic centimeters and a radius of 8 centimeters. Her work is shown below.
V=Bh
Step 1: 576(pie)= (pie)8^2h
Step 2: 576(pie) = 64(pie)h
Step 3: 576(pie)/64(pie) = 64(pie)/64(pie)h
Step 4: h=9(pie) cm
What error did Sandra make when calculating the height of the cylinder?
A. In step 1, she substituted into the volume formula incorrectly.
B. In step 2, she calculated 8^2 incorrectly. It should be 16 rather than 64.
C. In step 4, the (pie) should have canceled, making the correct answer 9 cm.
D. Sandra calculated the height of the cylinder correctly.
Answer:
See below.
Step-by-step explanation:
Step 3 should be: 576pi / 64pi = 64pi h / 64pi
Step 4: 9 = h.
I would say C and D.
Answer:
C. In step 4, the (pie) should have canceled, making the correct answer 9 cm.
Step-by-step explanation:
We know that,
The volume of a cylinder is,
[tex]V=\pi(r)^2h[/tex]
Where r is the radius of the cylinder,
h be the height of the cylinder,
Given,
[tex]V=576\pi \text{ cubic cm}[/tex]
r = 8 cm,
So, for finding the height of the cylinder the steps are as follows,
Step 1 : [tex]576\pi =\pi (8)^2h[/tex]
Step 2 : [tex]576\pi =\pi (64)h[/tex]
Step 3 : [tex]\frac{576\pi}{64\pi} =\frac{\pi (64)}{64\pi}h[/tex]
Step 4 : [tex]h = 9\text{ cm}[/tex]
Thus, it is clear that she had her mistake in 4th step,
She should cancel out [tex]\pi[/tex].
Option C is correct.
Need help plz .You have $2500 to invest in two different accounts. In order to save the money you need for college, you need to average 7% interest. If the two accounts pay 7.5% and 6% interest, how much should you invest in each account? Round to the nearest dollar amount.
A)$1667 in 7.5%, $833 in 6%
B)$1833 in 7.5%, $667 in 6%
C)$667 in 7.5%, $1833 in 6%
D)$833 in 7.5%, $1667 in 6%
Answer:
A)$1667 in 7.5%, $833 in 6%
Step-by-step explanation:
Let amount of money invested 6% account = x
Let amount of money invested 7.5% account = y
Then we get equations:
x+y=2500
or x=2500-y ...(i)
6% of x+7.5% of y=7% of (2500)
or 0.06x+0.075y=0.07(2500)
or 60x+75y=175000...(ii)
plug (i) into (ii)
60x+75y=175000
60(2500-y)+75y=175000
150000-60y+75y=175000
-60y+75y=175000-150000
15y=25000
y=$1666.66666667
or y=1667
plug into (i)
x=2500-y=2500-1667=833
Hence final answer is A)$1667 in 7.5%, $833 in 6%

Answer:
B
Step-by-step explanation:
Use the formula for radius and circle circumference.
[tex]d=2r \\ \\ C=2\pi r[/tex]
Since we know the diameter, if we divide that by 2, we can get the radius.
[tex]29.5/2=14.75[/tex]
Now we can plug that value into the circumference formula to get the circumference.
[tex]C=2(14.75)\pi \\ \\ C=29.5\pi \\ \\ C=93[/tex]
*Since we're rounding to the nearest inch.
You are to demonstrate that you understand what represents a function and what does not represent a function. You may do this by either writing a paragraph using complete sentences or drawing pictures with labels.
We know that functions are mathematical entities that assign unique outputs to given inputs. In other words, a function can't have repeated values in the input repeated x-value.
For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.
We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.

Step-by-step explanation:
Write down what you have for each pizza size.
small: s
Medium: (3/2) s
Large: (5/2) s
The only way I can see to do this is
s = L - M
s = 5/2 s - 3/2 s
s = 2/2 s
This of course is not exactly what you are looking for. There is no explicit formula that will tell you exactly how much dough is in a small pizza.
See the comment below posted by SqdanceFan. He is saying that M/L = (3/2)//(5/2) = 3/5
Also (M)/( S + M) = 3/5
But neither gives you an explicit formula for small, but it is a relationship. The fact that equality is achieved when both are zero is also true, but it does not solve the question. I don't think there's a good answer to this question.

The slop-intercept form of the equation of a line that passes through points (-2,-13) is y=5x-3 what is the point slope form of the equation of the equation for this line
Answer:
y + 13 = 5(x + 2)
Step-by-step explanation:
y=5x-3 what is the point slope form of this equation?
The point-slope form looks like y - k = m(x - h), where (h, k) is the given point and m is the given slope.
Here the given point is (-2, -13). Therefore, the desired equation is:
y -(-13) = 5( x - [-2] ), or
y + 13 = 5(x + 2)
Answer:
[tex]y+13=5(x+2)[/tex]
Step-by-step explanation:
The given function passes through (-2,-13).
The slope-intercept form of this equation is [tex]y=5x-3[/tex].
This implies that; the slope of the given function is;
[tex]m=5[/tex]
The point-slope form of this function is given by the formula;
[tex]y-y_1=m(x-x_1)[/tex]
We have [tex](x_1,y_1)=(-2,-13)[/tex]
We substitute the point and the slope into the function to obtain;
[tex]y--13=5(x--2)[/tex]
[tex]y+13=5(x+2)[/tex]

the baseball coach has 108 baseballs to share equally among 8 players. how many baseballs will be left over
Answer:
4 balls
Step-by-step explanation:
108/8=13.5 or 13 R 4
For this case we must divide the number of baseballs among the number of players. Let "x" be the variable that represents the amount of baseballs that each player has to play. So:
[tex]x = \frac {108} {8}\\x = 13.5[/tex]
Rounding down, [tex]x = 13.[/tex]
Each player gets 13 baseballs. Then there are:
[tex]108-13 * 8 = 108-104 = 4[/tex] baseballs
Answer:

Last year Jonathan was 6034 inches tall. This year he is 6514 inches tall. How many inches did he grow?
Answer:
480 in
BTW: Who could be that tall other than "Jonathan" of course?
Step-by-step explanation:
If you use subtraction...
6514-6034=480
to solve this problem subtract 6034 from 6514 to get 480
So he grew 480 inches which is equivalent to 40 feet
Which of the following is the slope-intercept form of the equation 3y = 2(x – 6)?
Answer:
y = 2/3x - 4
Step-by-step explanation:
To convert the equation \(3y = 2(x - 6)\) into slope-intercept form (\(y = mx + b\)), where \(m\) is the slope and \(b\) is the y-intercept, follow these steps:
1. Distribute the scalar on the right-hand side of the equation to both terms within the parentheses:
\(3y = 2x - 12\)
2. Isolate the variable \(y\) on one side by dividing the entire equation by 3:
\(y = \frac{2}{3}x - 4\)
Now the equation is in slope-intercept form, where the slope \(m\) is \(\frac{2}{3}\) and the y-intercept \(b\) is \(-4\). The final equation is:
\[y = \frac{2}{3}x - 4\]

For this case, we have that by definition, be given two functions f (x) and g (x). So:
[tex](f-g) (x) = f (x) -g (x)[/tex]
We have:[tex]f (x) = - 3x-5\\g (x) = 4x-2[/tex]
So:
(f-g) (x) = - 3x-5- (4x-2)
We have to:
[tex]- * + = -\\(f-g) (x) = - 3x-5-4x + 2[/tex]
Equal signs are added and the same sign is placed while different signs are subtracted and the sign of the greater is placed

Describe the domain of the logarithmic function, y = log10 x.
all numbers greater than or equal to zero
all numbers less than zero
all numbers greater than zero
Answer:
C). all numbers greater than zero
Step-by-step explanation:
We have been given a logarithmic function [tex]y=\log_{10}x[/tex].
Now we need to find about what is the domain of the given function then match with the correct choice from the given choices:
A). all numbers greater than or equal to zero
B). all numbers less than zero
C). all numbers greater than zero
By definition of logarithmic function we know that log is not defined for 0 or negative values.
Hence domain of given function must be
C). all numbers greater than zero
The answer is:
The third option,
All numbers greater than zero.
Why?The logarithmic function exists only from the numbers greater than zero to all the positive numbers, we must remember that the logarithmic function is the inverse to the exponential function, which domain is equal to all numbers greater than zero.
Hence, the answer is the third option:
All numbers greater than zero.

Math algebra 1 plsssss helppppp!!!!
Answer:
5. He rented 7 new releases videos
6. 4 3-bedrooms units.
7. length: 37, width: 18
8. 81 dimes, 47 quarters
Step-by-step explanation:
5. Videos
X: New releases
Y: Regular titles
EQ1: x + y = 18 (he rented 18 videos)
EQ2: 3x + 2y = 43 (he paid $43 for the 18 videos)
By EQ1, we can isolate y-value as y = 18 - x
We place this y-value into EQ2:
3x + 2(18 - x) = 43 and we solve:
3x + 36 - 2x = 43
3x - 2x = 43 - 36
x = 7
He rented 7 new releases videos
6. bedroom units
X: 2-bedrooms units
Y: 3-bedrooms units
EQ1: x + y = 7 (they have 7 units)
EQ2: 450x + 650y = 3950 (their monthly renting revenues)
By EQ1, we can isolate x as x = 7 - y (since we're looking for 3-bedrooms units), and place that value in EQ2:
450 (7 - y) + 650y = 3950
3150 - 450y + 650y = 3950
200y = 800
y = 4
So, they have 4 3-bedrooms units.
7. Rectangle
X: length
Y: width
EQ1: x + y = 55 (since perimeter is 110 and includes 2x + 2y)
EQ2: x = 2y + 1 (length is twice the with, plus 1)
Since we are asked to find both values, it doesn't matter by which we begin. By EQ1, we can do x = 55 -y, and place that value in EQ2, to get:
55 - y = 2y + 1
54 = 3y
y = 18
Place y = 18 in EQ1 to find x:
x + 18 = 55
x = 37
8. Dimes and quarters
X: dimes
Y: quarters
EQ1: x = y + 34 (34 more dimes than quarters)
EQ2: 10x + 25y = 1985 (total value of the collection)
Let's place the value of x from EQ1 in EQ2:
10 (y + 34) + 25y = 1985
10y + 340 + 25y = 1985
35y = 1645
y = 47
From EQ1, we then have
x = 47 + 34 = 81
So, we have 81 dimes ($8.10) and 47 quarters ($11.75), for a total of $19.85.
A relative frequency table is made from data in a frequency table. What is the value of K in the relative frequency table? Round your answer to the nearest percent.
Answer: k = 11%
Step-by-step explanation:
The relative frequency fr is calculated by dividing the frequency xi of a given Class by the number of total data.
[tex]fr = \frac{xi}{n} * 100\%[/tex]
In this problem there are 4 Class U ^ V and S ^ T
Notice in the first table that the total number of data is n = 19.
The relative frequency of k will be the frequency of T ^ V between the total number of data.
Notice in the first table that the frequency of the Class T ^ V is 2.
So
[tex]k = \frac{2}{19} * 100\%\\\\k = 11\%[/tex]
