It’s A&F, because when finding perimeter, you’re adding all of the sides together. Two of the sides are equal to “p”, while two of them are equal to “3p+3”, with this it would be “p+p+3p+3+3p+3”, and once simplified would result in “8p+6”.

1. The national mean (μ) IQ score from an IQ test is 100 with a standard deviation (s) of 15. The dean of a college wants to kno
Nat2105 [25]

Answer:

We conclude that the mean IQ of her students is different from the national average.

Step-by-step explanation:

We are given that the national mean (μ) IQ score from an IQ test is 100 with a standard deviation (s) of 15.

The dean of a college want to test whether the mean IQ of her students is different from the national average. For this, she administers IQ tests to her 144 students and calculates a mean score of 113

Let, Null Hypothesis, H_0 : \mu = 100 {means that the mean IQ of her students is same as of national average}

Alternate Hypothesis, H_1 : \mu\neq 100  {means that the mean IQ of her students is different from the national average}

(a) The test statistics that will be used here is One sample z-test statistics;

               T.S. = \frac{Xbar-\mu}{\frac{s}{\sqrt{n} } } ~ N(0,1)

where, Xbar = sample mean score = 113

              s = population standard deviation = 15

             n = sample of students = 144

So, test statistics = \frac{113-100}{\frac{15}{\sqrt{144} } }

                             = 10.4

Now, at 0.05 significance level, the z table gives critical value of 1.96. Since our test statistics is more than the critical value of z which means our test statistics will fall in the rejection region and we have sufficient evidence to reject our null hypothesis.

Therefore, we conclude that the mean IQ of her students is different from the national average.

During a storm, why do you see the flash of lightning before you hear the roar of thunder? What would it mean if you saw the fla
Lubov Fominskaja [6]
The speed of light is faster than the speed of sound. So that's why you see a flash of lightning before the roar of thunder. If you heard it at the same time as you saw it, well I will be praying for you. It would literally be exactly where you are. If you hear the thunder a long time after the flash, it means the lightning is far away.

T/5=miles away when T is time from the strike of lightning to hearing thunder

If 25% of a number is 100, what is the number
RSB [31]
Let us assume that the number is = x
Then the equation can be written as
25x/100 = 100
25x = 100 * 100
25x = 10000
x = 10000/25
x = 400
So the required number is 100. In this case, understanding the question is of immense importance. Once the words of the problem are converted to numbers, then there is no issue left. It is a straight forward problem otherwise. Hopefully i have explained this problem to you for answering any such problems in the future.
