#21 the answer is does √ 9^2 + 2^2
a^2 + b^2 = c^2
9^2 + 2^2 = c^2
√ 9^2 + 2^2 = √ c^2

Answer:
0.9%
Step-by-step explanation:
We have been given that Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm.
We will use percentage error formula to solve our given problem.





Therefore, Rich's percent error in calculation is 0.9%.
Answer:
0.128
Step-by-step explanation:
We know the probability for any event X is given by,
,
where p is the probability of success and q is the probability of failure.
Here, we are given that p = 0.533.
Since, we have that q = 1 - p
i.e. q = 1 - 0.533
i.e. q = 0.467
It is required to find the probability of 4 wins in the next 5 games i.e. P(X=4) when n = 5.
Substituting the values in the above formula, we get,

i.e. 
i.e. 
i.e. i.e. 
Hence, the probability of 4 wins in the next 5 games is 0.128.
