Arecent study showed that there were 611 challenges made to referee calls in professional tennis singles play. among these challenges, 172 were upheld with the call overturned. assume that 30% of challenges are successfully upheld with the call overturned. let x be the number of overturned calls out of the 611 challenges. using the normal approximation to the binomial, find the probability that among the 611 challenges the number of overturned calls is 172 or fewer. round to two decimals.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
