Answer:

Step-by-step explanation:

<em>NOTE: If the lines around the equation are absolute value lines, the answer will be the positive version of the answer given. The lines looked like you were just clarifying where the equation was in the sentence, but I could be wrong.</em><em> </em>

First, plug all the numbers in. So it would be (2(3)(-2)^{2} ). Then you would apply the exponant to the -2. So that would be (2(3)(4)). And that equals 24.

➷ Calculate the number of hours:

24 x 3 = 72

72/13 = 5.5....

This is 5 whole half lives

You have to half the value 5 times

149/2 = 74.5

74.5/2 = 37.25

37.25/2 = 18.625

18.625/2 = 9.3125

9.3125/2 = 4.65625

The closest value is B. 3.21 so that should be the answer

Does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant criteria?Tem

Answer:

B. No, this distribution does not appear to be normal

Step-by-step explanation:

Hello!

To observe what shape the data takes, it is best to make a graph. For me, the best type of graph is a histogram.

The first step to take is to calculate the classmark`for each of the given temperature intervals. Each class mark will be the midpoint of each bar.

As you can see in the graphic (2nd attachment) there are no values of frequency for the interval [40-44] and the rest of the data show asymmetry skewed to the left. Just because one of the intervals doesn't have an observed frequency is enough to say that these values do not meet the requirements to have a normal distribution.

The answer is B.

I hope it helps!
