Answer:

0.13591.

Step-by-step explanation:

We re asked to find the probability of randomly selecting a score between 1 and 2 standard deviations below the mean.

We know that z-score tells us that a data point is how many standard deviation above or below mean.

To solve our given problem, we need to find area between z-score of -2 and -1 that is P(-2.

We will use formula P(a to solve our given problem.

P(-2

Using normal distribution table, we will get:

P(-2

P(-2

Therefore, the probability of randomly selecting a score between 1 and 2 standard deviations below the mean would be 0.13591.

The square shown has sides of length 7z^5 decimeters. Find its area
VikaD [51]

For this case we have that by definition, the area of a square is given by:

A = l ^ 2

Where:

l: It's the side of the square

We have, according to the statement data, that:

l = 7z ^ 5 \ dm

Then, the area is given by:

A = (7z ^ 5 \ dm) ^ 2

By definition of power properties we have to:

(a ^ n) ^ m = a ^ {n * m}

So:

A = (7z ^ 5 \ dm) ^ 2 = 49z^{5 * 2} \ dm ^ 2 = 49z^{10} \ dm ^ 2

Answer:

The area of the square is: 49z^{10} \ dm ^ 2

Difference of 2 perfec squares is
(a^2)-(b^2)




if the exponents are both even and the coeficient (the number in front) are perfect squares, then it is difference t 2 perfect squares

first one
8 is not perfect square


2nd one
(4e^4)^2-(9g^2)^2


third
25 is odd, so it cannot be split up into 2 nice numbers

4th
