A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 10 child bikes and 12 adult bikes in the week. (2 points) a No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 b No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 c Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 d Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Answer:
5.06

Which function is the inverse of h(x) = 18x+7/3?
Answer:
f^-1 (x)= x/18 - 7/54
Step-by-step explanation:
The inverse function of h(x) is x/18 - 7/54
What is inverse function?The inverse function is defined as a function obtained by reversing the given function.
Given function h(x) = 18x+7/3
Let g(x) function is the inverse function of h(x)
Suppose y = h(x)
y = 18x+7/3
y-7/3 = 18x
y/18 - 7/54 = x
g(x) = x/18 - 7/54
Hence g(x) = x/18 - 7/54 is the inverse function of h(x)

Suppose the distribution of a set of scores has a mean of 47 and a standard deviation of 14. If 4 is added to each score, what will be the mean, standard deviation, and variance of the distribution of new scores?
Answers:
New Mean = 51New Standard Deviation = 14New Variance = 196================================================
Explanation:
Consider the set {x1,x2,x3,...,xn}. The numbers 1,2,3,...,n represent the index of each x value. So we have n numbers we want to find the average.
The sum of those values is
S = x1+x2+x3+...+xn
When dividing that over n, we get the average A
A = S/n
A = (x1+x2+x3+...+xn)/n
-----------------
Now consider adding 4 to each x value
We have this new set
{x1+4, x2+4,x3+4,...,xn+4}
The new sum T is
T = (x1+4)+(x2+4)+(x3+4)+...+(xn+4)
T = (x1+x2+x3+...+xn) + (4+4+4...+4)
T = S + 4n
Divide both sides by n
T/n = (S+4n)/n
T/n = (S/n) + (4n/n)
T/n = (S/n) + 4
T/n = 47+4
T/n = 51
The new average T/n is 4 larger compared to the old average S/n. So we just add 4 to the old average 47 to get 51 as the new average.
-----------------
If we shift every value the same amount, then the standard deviation and variance will not change. This is because both of those items measure how spread out a distribution is. Shifting each item the same amount, keeps the same spread and shape of the distribution. If only affected some of the items, then the standard deviation and variance would change.
Note that,
variance = (standard deviation)^2
variance = (14)^2
variance = 196

Explain why 3 : 2 and 9 : 8 are not equivalent ratios.
Answer:because 2 can’t go into 9 and 8 can’t go into 3
Step-by-step explanation
-
The ratio shows how many times one value is contained in another value.
3/2 ≠ 9/8
The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
3:2 and 9:8
We will simplify it in its simplest form.
3:2 = 3/2
This is the simplest form.
9:8 = 9/8
This is in its simplest form.
So,
3/2 is not equal with 9/8
If the two ratios are the same we can call them equivalent ratios.
Thus,
3/2 ≠ 9/8
The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios.

Answer:
Step-by-step explanation:
1) Order the numbers using the data from 2001-2004
70,60,81,19
2) Add them all together
70+60+81+19= 230
3) Divide the answer you got by the amount of numbers there are
70,60,81,19=4 numbers
230/4 = 57.5
4) Therefore the average rate of change between 2001-2004 is 58 employees (since you can't have a fraction of a person you would have to round)

Find the slope
(2, 4) (0,4)
Answer:
The slope is 0
Step-by-step explanation:
Slope can be found using the expression [tex]\frac{y2-y1}{x2-x1}[/tex]
In this case,
y2 = 4
y1 = 4
x2 = 0
x1 = 2
[tex]\frac{4-4}{0-2}[/tex] = 0/-2 = 0
