If X is a normal random variable that has mean mu = 20 and standard deviation sigma = 2, the standardized value of X = 16 is

Answers

Answer 1

Answer:

The standardized value is -2

Step-by-step explanation:

Given

[tex]mu = 20[/tex] -- mean

[tex]\sigma = 2[/tex] --- standard deviation

Required

Determine the standardized value of X = 16

The standardized value (S) is calculated using:

[tex]S = \frac{X - mu}{\sigma}[/tex]

This gives:

[tex]S = \frac{16 - 20}{2}[/tex]

[tex]S = \frac{- 4}{2}[/tex]

[tex]S = -2[/tex]

The standardized value is -2

Julie is using construction methods to inscribe a square into circle A. She constructed EF the perpendicular bisector to CD. To complete
the construction, what must Julie do next?

Answers

Answer:

Step-by-step explanation:

C

Julie must draw a line joining the C to E, then E to D, D to F, and F to C, she will get a square into a circle.

What is a circle?

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

To construct a square into the circle A.

Let's assume the CD is the diameter of the circle.

By joining the point C and point D we will get a line CD(diameter of the circle)

Draw a line EF which Bisect the line CD.

Join point E and F which are on the circle and join them.

Draw a line joinig the point C to E, then E to D, then D to F, and F to C.

We will get a square inscribed into a circle.

Thus, Julie must draw a line joining the C to E, then E to D, D to F, and F to C, she will get a square into a circle.

The only equation is y = - 2 x +3

For d) try in all equations if replacing x with 2, gives you an answer "2" for y as well.

Remember that in PEMDAS, you do the parentheses first.

1. For each answer choice, do whatever is in the parentheses first.

2. Multiply that number to the one outside the parentheses

Hint: For this problem, If all the signs in the answer choice are multiplication, they will equal the same number.

8. A certain module has 2 pages. How many pages does the module have?
plsplsplspls​

Answers

Step-by-step explanation:

The small number above the 2 is called an exponent, and we use exponents to shorten a number so it's not so large. So here, the 6 is an exponent, and when we have a problem like this where we have to figure out something like 2^6, as shown above, we grab the base number, which in this case is 2, and we multiply it by itself 6 times, since 6 is the exponent. So basically you have to multiply the base number (2) by itself the same number of times as whatever the exponent is. So we have 2 × 2 × 2 × 2 × 2 ×2, and when you multiply all of this, you get 64. So the module has 64 pages.
