Every year, more than 100,000 testers take the Law School Admission Test (LSAT). One year, the scores had a mean and standard de

viation of approximately 151 and 9 points, respectively. Suppose that in the scoring process, test officials audit random samples of 36 tests, which involves calculating the sample mean score x/bar. Calculate the mean and standard deviation of the sampling distribution of x/bar

Answer:

491400

Step-by-step explanation:

Given : A club has 28 members.

To Find : . How many ways are there to choose four members of the club to serve on an executive committee?

Solution:

We are supposed to choose  four members of the club out of 28.

So, we will use combination

Formula : ^nC_r=\frac{n!}{r!(n-r)!}

n = 28

r = 4

Substitute the values :

^{28}C_{4}=\frac{28!}{4!(28-4)!}

^{28}C_{4}=\frac{28 \times 27 \times 26 \times 25 \times 24!}{4!(24)!}

^{28}C_{4}=\frac{28 \times 27 \times 26 \times 25 \times 24}{4 \times 3 \times 2 \times 1}

^{28}C_{4}=491400

Hence there are 491400 ways o choose four members of the club to serve on an executive committee

I need an answer for this.

I think the answer is D because you have to move the decimal three times anyway, then you only need to add seven more zeroes to make it correct (in my opinion).

Answer:

Can not be determined (CNBD)

Step-by-step explanation:

In the given triangle ACI,

M is the mid point of CI, So we have

CM= MI

also AM=AM   ( reflexive property )

So far we have two pairs of corresponding sides are congruent in ΔCAM and ΔIAM

To prove that ΔCAM≅ΔIAM using SSS (side side side ) congruence theorem

we should have AC =AI , but it is not given,so we can not say that AC=AI

To prove that ΔCAM≅ΔIAM using SAS (side angle side ) congruence theorem

we should have ∠AMC=∠AMI, but it is not given,so we can not say that  ∠AMC=∠AMI

We can not determine that ΔCAM is congruent to which triangle

Hence the answer is Can not be determined (CNBD)
