Answer:
a. 135 is correct
Step-by-step explanation:
We have the following information:
dogs lover: 150
cats lover: 120
as the null hypothesis:
H, there are equal number of dogs lover and cats lover, so the expected frequency in each cell will be equal and that is:
f = (150 + 120) / 2
f = 270/2 = 135
so option a. 135 is correct

Answer:
40 miles
Step-by-step explanation:
let distance be d and time be t
Since d varies directly with t, then the equation relating them is
d = kt ← k is the constant of variation
To find k use the condition d = 75 when t = 3
k = 
= 
= 25
d = 25t ← equation of variation
when t = 1.6, then
d = 25 × 1.6 = 40 miles
The cable is 25 feet long! draw a diagram use the pythagorean theorem (a^2+b^2=c^2) to find the length of the cable (or in other cases, the hypotenuse)
