A. Multiply the radius by 2 to find the diameter. b. Multiply the diameter by π. c. Measure the radius of the lid. Which is the

Nimfa-mama [501]

Answer:

The Correct order to calculate the circumference of a circular lid

1 ) Measure the radius of the lid.

2 ) Multiply the radius by 2 to find the diameter.

3 ) Multiply the diameter by π.

Step-by-step explanation:

Circumference :

In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is defines as the linear or Circular distance around it.

It is given by the formula:

$Circumference= \pi d$

$d =Diameter = 2\times Radius$

The Correct order to calculate the circumference of a circular lid

1 ) Measure the radius of the lid.

Radius will be measured

2 ) Multiply the radius by 2 to find the diameter.

Diameter = 2 × Radius

3 ) Multiply the diameter by π.

π × Diameter = Circumference

Then we will get the Circumference,

$Circumference= \pi\times d$

7 times a number equals 3 less than 5 times that number. what is the number?

inessss [21]

First the equation would look like this:

7n = 5n - 3

7n - 5n = 5n - 5n - 3 -Subtract 5n from both sides. Which gives you...

2n = -3

2n/2 = -3/2 -Divide both sides by 2

n = -1.5

Hope this helps!

Suppose the mean height for men is 70 inches with a standard deviation of 2 inches. What percentage of men are more than 72 inch

hichkok12 [17]

The percentage of men is more than 72 inches tall will be 0.15866.

<h3>What is the z-score?</h3>

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x – μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

Suppose the mean height for men is 70 inches, with a standard deviation of 2 inches.

Then the percentage of men are more than 72 inches tall will be

z = (72 – 70) / 2

z = 1

The percentage of men is more than 72 inches tall will be

P(x > 72) = P(z > 1)

P(x > 72) = 1 – P(x < 72)

P(x > 72) = 1 – 0.84134

P(x > 72) = 0.15866

Thun, the percentage of men are more than 72 inches tall will be 0.15866.

More about the z-score link is given below.
