Which equations are related equations to x + 8 = 22? Select each correct answer. x = 22 + 8 x + 22 = 8 8=22−x x=22−8

vivado [14]

I'm not entirely sure but I believe it would be 8=22-x because x=16 so 8 does equal 22-16

Four friends decide to go to McDonald’s. It was reported that the location they visited filled approximately 90.9% of the orders

zmey [24]

Answer:

0.0069% probability that none of the orders will be filled correctly, using the binomial probability distribution.

Step-by-step explanation:

For each order, there are only two possible outcomes. Either it is filed correctly, or it is not. The probability of an order being filed correctly is independent from other orders. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[\tex]In which [tex]C_{n,x}[\tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[\tex]And p is the probability of X happening.It was reported that the location they visited filled approximately 90.9% of the orders correctly.This means that [tex]p = 0.909$
