Answer:

Option C, >

Step-by-step explanation:

<u>Step 1: Determine the correct answer </u>

Since they have the same denominator, you can directly view the top without comparing the bottom. To compare just look at the top two numbers to decide which of the two is bigger. Looking into the problem I see that the two numerators, the top number of a fraction, are 15 and 12. Now, compare these two numbers.

15 _ 12

15 <u>></u> 12

So... this shows that the first fraction in bigger than the second.

What is the probability that an individual, selected at random, will score below the mean on any normally distributed characteri

dedylja [7]

Answer:

the probability that an individual, selected at random, will score below the mean on any normally distributed characteristic is just about 0.5.

Step-by-step explanation:

This probability in normal distribution corresponds to z-score of 0. Using normal distribution tables.

P(z < 0) = 1 - P(z ≥ 0) = 1 - 0.5 = 0.5

Which is very logical, to score below the mean on a normal distribution, the probability is just less than 0.5.

Three semicircles are placed in a rectangle, as shown below. The length of the rectangle is 72m. Find the area of the shaded reg

MArishka [77]

<h2>Step-by-step explanation:</h2>

<h3>Width of rectangle = 7 cm</h3>

<h3>because ∵ width of rectangle is equal to the radius of each semicircle.</h3>

<h3>therefore ∴ radius of each semicircle (r) = 7 cm.</h3>

<h3>therefore ∴ Diameter of each semicircle = 14 cm</h3>

<h3>therefore ∴ Length of rectangle = 3 x 14 = 42 cm.</h3>
