Answer: 
Step-by-step explanation:
Let 
be the average number of hours a person drive without adding the product.
Given claim : An infomercial claims that a woman drove 33 hours without oil.
i.e. 
It is known that the null hypothesis always contains equal sign and alternative hypothesis is just opposite of the null hypothesis.
Thus the null and alternative hypothesis for the given situation will be :-
Answer:
B. The company hires 10 employees every year.
Step-by-step explanation:
One way to look at this is to look at the units on the number 10. Working strictly with units, we get ...
f(x) = 10x . . . . . . f(x) is employees, x is years
employees = 10·years
Dividing by years, we find the meaning of "10":
employees/year = 10
The division symbol (/) is read as "per", so this means the number 10 in the equation is the number of employees per year that are hired.
10 employees are hired every year.
Answer:
2.7 in²
Step-by-step explanation:
similar triangles have the same angles, and all side lengths (or other distances) of one triangle have the same scaling factor to the side lengths of the other triangle.
so, we know the relation between the 2 baselines is 2/3, as this is the factor to turn the baseline of the large triangle into the baseline of the smaller triangle.
in other words
EF = BC × 2/3
2 = 3 × 2/3
correct
how do we calculate the area of a triangle ?
Area = baseline × height / 2
from BAC we know
Area = 6
baseline = 3
height = ?
6 = 3 × height / 2
12 = 3 × height
height = 4
aha !
now, EDF has a height too that we need to calculate is Area. and this height has the same scaling factor compared to the larger triangle as the side lengths : 2/3
so, for EDF we know
Area = ?
baseline = 2
height = 4 × 2/3 = 8/3
therefore, the area is
Area = (2 × 8/3) / 2 = (16/3) / 2 = 8/3 = 2.66666... ≈ 2.7
the shirt answer would be :
we know from the 2 baselines that the scaling factor for each distance is 2/3.
for the area we need to multiply 2 distances, so that means we have to multiply both by 2/3. and so on the formula for the area we have to use 2/3 × 2/3.
2/3 × 2/3 = 4/9
=>
Area small = Area large × 4/9 = 6 × 4/9 = 24/9 = 8/3 ≈ 2.7
