Answer:
5/9 cubic yards
Step-by-step explanation:
Just so L*W*H=24(36)(30)= 25920 cubic inches=25920 (1 in*1 in* 1 in)
36 in=1 yd
so
1 in =1/36 yd
do divide 25920 by (36*36*36)
The answer in cubic yards is 5/9 cubic yards

The graph shows how fast a strand of human hair grows.
How many inches would the hair have grown in 5 months
Answer:
2 and a half @ 2.5 inches (sorry i can't type the fraction)
Step-by-step explanation:
english is my second language so sorry if you doesn't understand:(1/2, 1/4)=(x,y)
based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.
this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.
since the '5 months-hair-length' is above about 2 grid above 2 inch:
2 inch + 0.5 inch= 2.5 inch

Find the zero of 5x – 20 = 0.
Question 10 options:
a)
5
b)
4
c)
0
d)
-20
Answer:
The correct option B) 4.
Step-by-step explanation:
Consider the provided equation.
[tex]5x - 20 = 0[/tex]
To find the zero simplify the above equation as shown
Add 20 from both the sides.
[tex]5x - 20+20 = 20[/tex]
[tex]5x= 20[/tex]
Divide 5 from both the sides.
[tex]\frac{5x}{5}=\frac{20}{5}[/tex]
[tex]x=4[/tex]
Thus, the zero of the equation is [tex]x=4[/tex].
Hence, the correct option B) 4.
Henry recorded the number of miles he biked each day for a week. His miles were 25, 40, 35, 25, 40, 60, and 75. Enter the data into the statistics calculator.
what is the standard deviation of the miles Henry biked to the nearest tenth?
Answer:
17.1
Step-by-step explanation:
1. Find the Mean
(25+40+35+25+40+60+75)/7 = 42.9
2.For each number, subtract the Mean and square the result.
(25-42.86)^2=319
(40-42.86)^2=8.2
(35-42.86)^2=61.8
(25-42.86)^2=319
(40-42.86)^2=8.2
(60-42.86)^2=293.8
(75-42.86)^2=1033
3. Find the Mean of those squared differences.
(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9
4.Take the square root of that and this is what you want.
square root of 291.9 = 17.1
The standard deviation of the given data is 17.1
What is standard deviation?Standard deviation meaning in statistics is a measure of how much the data points vary from the mean or average. It is calculated as the square root of the variance, which is the average of the squared deviations of each data point from the mean.
Given is a data set, we need to find the standard deviation of the data set,
S = 25, 40, 35, 25, 40, 60, 75
Finding the mean =
(25+40+35+25+40+60+75)/7 = 42.86
Finding the variance =
(25-42.86)² = 319
(40-42.86)² = 8.2
(35-42.86)² = 61.8
(25-42.86)² = 319
(40-42.86)² = 8.2
(60-42.86)² = 293.8
(75-42.86)² = 1033
(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9
Therefore, the standard deviation =
√291.9 = 17.1
Hence, the standard deviation of the given data is 17.1

Describe the relationship between the area and the perimeter of two squares with a length of 2.5 and 5.
For this case we have by definition, that the area of a square is given by:
[tex]A = l ^ 2[/tex]
While the perimeter is given by:
[tex]p = 4l[/tex]
Where:
l: It's the side of the square.
Square 1: [tex]l = 2.5[/tex]
[tex]A = (2.5) ^ 2 = 2.5 * 2.5 = 6.25\\p = 4 (2.5) = 10[/tex]
Square 2: [tex]l = 5[/tex]
[tex]A = (5) ^ 2 = 5 * 5 = 25\\p = 4 (5) = 20[/tex]
We can see that the perimeter of the second square is double that of the first. In addition, the second area is four times that of the first square.

Answer:
1730
Step-by-step explanation:
The exponential function is of the form
y = a × [tex]b^{n}[/tex]
where y is the insect population and n the number of weeks
a and b have to be found by using values from the table.
Using (0, 20), then
20 = a × [tex]b^{0}[/tex] ⇒ a = 20
Using (1, 30), then
30 = 20 × [tex]b^{1}[/tex] ⇒ b = [tex]\frac{30}{20}[/tex] = 1.5
Hence
y = 20 × [tex]1.5^{n}[/tex] ← exponential function
When n = 11
y = 20 × [tex]1.5^{11}[/tex] ≈ 1730 ( nearest whole number )

Answer:
13
Step-by-step explanation:
x y
y=1/2x+3 and passes through the point (10,-5) 10 = x and -5 =y 1/2(10) - this mean times
-5 = 1/2(10) +3
1/2(10/1) = 1 x 10 and 2 x 1 = 10/2 = 5

It is unnecessary to put two of the same numbers. You only need to put one.
{2, 3, 8}
Hope this helped!
~Just a girl in love with Shawn Mendes
Answer: Last option.
Step-by-step explanation:
By definition, the Domain is the set of all the x-coordinates of the ordered pairs (input values) and the Range is the set of all the y-coordinates of the ordered pairs (output values)
In this case you have the following relation:
[tex]R:[/tex]{[tex](3, 5), (8, 6), (2, 1), (8, 6)[/tex]}
You can identify that the set of all the x-coordinates is:
{[tex]3,8,2,8[/tex]}
You can observe that the input value 8 appears twice, but you only need to write it once.
Therefore, the Domain of that relation is:
[tex]Domain:[/tex]{[tex]2,3,8[/tex]}
Determine whether the formula describes y as a function of x. Explain your reasoning.y = -x
Answer:
Yes, [tex]y=-x[/tex] describes "y" as a funcion of "x", because each input value (value of "x") has only one ouput value (value of "y").
Step-by-step explanation:
By definition, a relation is a function if each input value (value of "x")has only one ouput value (value of "y").
We need to remember that "y as a function of x" means that "x" is the independent variable and "y" is the dependent variable or, in other words, the value of the variable "y" depends upon the value of the variable "x".
Then, [tex]y=-x[/tex] is a function, because each input value has one and only one output value. For example:
If [tex]x=-2[/tex], then:
[tex]y=-(-2)=2[/tex]
If [tex]x=1[/tex], then:
[tex]y=-(1)=-1[/tex]
If [tex]x=5[/tex], then:
[tex]y=-(5)=-5[/tex]
Therefore, [tex]y=-x[/tex] describes "y" as a funcion of "x".

PLEASE HELP :(
Answer:
So value of x = -1 and value of y = 1
Solution Set (-1,1)
Step-by-step explanation:
x+y =0
x-y +2 =0
We need to solve these equations to find value of x and y
x+y =0 eq(1)
Add -2 on both sides
x-y = -2 eq(2)
Add equation 1 and 2
x+y = 0
x-y =-2
______
2x = -2
x = -2/2
x = -1
Now, put value of x = -1 in equation 1
x+y = 0
-1 +y =0
Adding +1 on both sides
-1+1+y = 0+1
y = 1
So value of x = -1 and value of y = 1
Solution Set (-1,1)
We would plot the values of x= -1 and y = 1 on the graph.

the scatter plot graph shows the average annual income for a certain profession based on the number of years of experience which of the following is most likely to be the equation of the trend line for this set of data?
a. I=5350E +37100
b. I=5350E-37100
c. I=5350E
d. E=5350E+37100
Answer:
a. I=5350E +37100
Step-by-step explanation:
The trend line does not start at the origin so we can immediately rule out option C
The equation should be in slope intercept form so we can rule out option D, since E is the x axis and we are looking for y = mx + b not x = mx + b.
Option B is ruled out because if we plug in the value of E = 2 then we get:
I = 5350(2) - 37100
I = 10700 - 37100
I = -16400

An egg farmer determined that it costs him $0.05 per egg to harvest chicken eggs. In addition, he spends $1000 each month for the upkeep of his farm.
Write an equation in slope-intercept form that represents the monthly cost of the farm in dollars y, when it produces x eggs.
Which answer correctly identifies the slope and equation for this situation?
select the corect answer.
A.The slope is −1000 because this is the monthly cost for upkeep at the farm. The equation is y=−1000x−0.05.
B.The slope is −0.05 because this is the cost per egg. The equation is y=−0.05x+1000.
C.The slope is 0.050.05 because this is the cost per egg. The equation is y=0.05x+1000.
D.The slope is 1000 because this is the monthly cost for upkeep at the farm. The equation is y=1000x.
Answer:
Step-by-step explanation:
Total cost here is a sum that increases with the number of eggs produced.
TC(x) = $1000 + ($0.05/egg)x, where x is the number of eggs produced.
The y-intercept is $1000; it is independent of the number of eggs produced.
The slope is $0.05/egg.
Answer C is correct.
The equation that represents the monthly cost y for producing x eggs is y = 0.05x + 1000, where 0.05 (the cost per egg) is the slope, and 1000 (the monthly upkeep cost) is the y-intercept. Thus, the correct answer is option C.
Explanation:In the given scenario, the cost per egg is $0.05, which makes this the slope of the equation, as this is the cost that changes with the number of eggs produced, represented by x. The fixed cost of $1000 per month for the upkeep of the farm is the y-intercept because this cost does not change regardless of the quantity of eggs produced. Therefore, using y = mx + b (slope-intercept form), where y is the total cost, m is the cost per egg, x is the number of eggs, and b is the monthly upkeep cost, we get:
y = 0.05x + 1000
Hence, the correct answer is C: The slope is 0.05 because this is the cost per egg. The equation is y = 0.05x + 1000.
