Answer:

Standard error

Step-by-step explanation:

The standard deviation of the distribution of sample means is called the standard error of the means.

It is denoted by: \sigma_{\bar X}

The standard error is calculated using the formula: \sigma_{\bar X}=\frac{\sigma}{\sqrt{n} }

where n is the sample size and \sigma is the population standard deviation.

Write a function for the tranformations described below:
IrinaK [193]

The function after the transformation has an equation of y = ∛(x - 7) + 5

<h3>How to determine the equation of the transformation?</h3>

The transformation statement is given as

"The cubic function shifts 7 units right and 5 units up."

A cubic function is represented as

y = ∛x

So, the transformations are:

  • Shifts 7 units right
  • Shift 5 units up

Mathematically, this can be represented as

(x, y) = (x - 7, y + 5)

So, we have the following equation

y = ∛(x - 7) + 5

Hence, the equation of the transformation is y = ∛(x - 7) + 5

Find three consecutive integers such as two times the first integer, plus three times the second integer, minus the third intege
NikAS [45]

The three consecutive integers are 5, 6, and 7.

What are consecutive integers?

Whole numbers that follow one another without a gap are known as consecutive integers. A few examples of consecutive integers are 15, 16, and 17, 1,2 and 3, and so on.

Finding the Consecutive Integers

Let the three consecutive integers be a, a + 1, and a + 2.

These three consecutive integers are to be such that two times the first integer when added to three times the second integer minus the third integer, it is equal to 21.

⇒ 2a + 3(a+1) - (a+2) = 21

2a + 3a + 3 - a -2 = 21

5a - a + 3 - 2 = 21

4a + 1 = 21

4a = 20

a = 20/4

a = 5

∴ a+1 = 5+1

a+1 = 6

And, a+2 = 5 + 2

a +2 =7

Hence, the three consecutive integers come out to be 5, 6, and 7
