The answer is 0.3 (1/3.)
Proof?
f(0.3) = 18(0.3) + 8
f(0.3) = 6 + 8
f(0.3) = 14
14 = 14

Since the pool is square, the four sides are equal.
Therefore the length of one side = sqrt(292) = 17.1 to the nearest tenth.
A. The ratio of soccer balls to all balls are 4:25
All the balls combined are 50 balls
8 of the balls are soccer balls so that makes the ration 8:50
In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.

Answer:
There is evidence to prove that mean is less than 60 hours.
Step-by-step explanation:
Given that the mean work week for engineers in a start-up company is believed to be about 60 hours.
Sample size taken = 10

(left tailed test )
Data (length of mean work week): 70; 45; 55; 60; 65; 55; 55; 60; 50; 55.

Mean difference = -3
Test statistic t =mean differene/std error
= -20.72
p value <0.00001
Since p < 0.05 at 5% level we reject H0
There is evidence to prove that mean is less than 60 hours.
