G=m/x
G-gallons
m-miles
x-miles per gallon
19.2= 1293.6/x
x=1293.6/19.2
x= 67.375mpg
Therefore, the vehicle traveled 67.375 miles to 1 gallon
Answer:
A and B are both 3.
Step-by-step explanation:
The given polynomial is 
.
We factor the GCF to obtain:
We factor further by grouping to get:
![3x[x^2(x-6)+3(x-6)]](https://tex.z-dn.net/?f=3x%5Bx%5E2%28x-6%29%2B3%28x-6%29%5D)
We compare this to the given factored expression:
We must have A=3,B=3, C=-6
The random sample of the students is an illustration of sampling
The chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.
<h3>How to determine the reason chi square is not appropriate?</h3>
The dataset is given as:
Monday 34
Tuesday 29
Wednesday 32
Thursday 28
Friday 19
The variable of the above dataset is a not a categorical dataset.
One of the conditions of the chi-square test for goodness of fit test is that the variable under study must be categorical.
Hence, the chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.

A.
y = 7 - |x| = 7 - 2 = 5
b.
y = x² - 1 = 2² - 1 = 4 - 1 = 3
c.
y = √(x + 14) = √(2 + 14) = √16 = 4
Answer:
103
Step-by-step explanation:
it has to add up to 180 so
180-77=103
