Answer : The correct option is, (B) 17

Step-by-step explanation :

From the Venn diagram we Conclude that:

Number of employees speak Spanish = 8

Number of employees speak Chinese = 6

Number of employees speak Spanish and Chinese (both) = 3

As per question, now we have to determine the number employees who speak either Spanish or Chinese (or both).

Number of employees speak either Spanish or Chinese (or both) = Number of employees speak Spanish + Number of employees speak Chinese + Number of employees speak Spanish and Chinese (both)

Number of employees speak either Spanish or Chinese (or both) = 8 + 6 + 3

Number of employees speak either Spanish or Chinese (or both) = 17

Thus, the number of employees speak either Spanish or Chinese (or both) are, 17

What is exact the slope of the line through (-9, 6) and ( -3 ,9 )
Tatiana [17]
Slope = (y2 - y1) / (x2 - x1)
(-9,6)....x1 = -9 and y1 = 6
(-3,9)...x2 = -3 and y2 = 9
now we sub and solve
slope = (9 - 6) / (-3 - (-9) = 3 / (-3 + 9) = 3/6 = 1/2 <=

Suppose that a recent poll found that 49​% of adults believe that the overall state of moral values is poor. Complete parts​ (a)
Lunna [17]

Answer:

The mean of X is 122.5 and the standard deviation is 7.9.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not believe this. The probability of an adult believing this is independent of other adults. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

In this problem, we have that:

n = 250, p = 0.49

So

E(X) = np = 250*0.49 = 122.5

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{250*0.49*0.51} = 7.9

The mean of X is 122.5 and the standard deviation is 7.9.
