Tju [1.3M]

Answer:

C. 20

Step-by-step explanation:

The order in which the members are selected is important. The first one selected is the president and the second is the vice president.

So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this problem:

2 people are going to be chosen from a set of 5. So

P_{(5,2)} = \frac{5!}{(5-2)!} = 20

So the correct answer is:

C. 20

Answer:

About 99.7% of births would be expected to occur within 51 days of the mean pregnancy​ length

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Standard deviation = 17.

About what percentage of births would be expected to occur within 51 days of the mean pregnancy​ length?

51/17 = 3.

So, within 3 standard deviations of the mean.

About 99.7% of births would be expected to occur within 51 days of the mean pregnancy​ length

vesna_86 [32]

Answer:12 m

Step-by-step explanation:

Given

Width of garden W=8\ m

Total fencing T=40\ m

If Lulu has enough fencing to go around her rectangular garden then , it should be equal to perimeter of garden

Suppose L is the length of garden

Therefore perimeter is P=2(L+W)

2(L+W)=40

L+W=20

L=20-8=12\ m

thus length of fencing is 12\ m
