Each month, an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard d

Annette [7]

a) For x = 27:

z = 27-28/2 = -0.5

For x = 31:

z = 31-38/2 = 1.5

From the normal distribution table, P(27 < x < 31) = P(-0.5 < z < 1.5) = P(z < 1.5) - P(z < -0.5) = 0.9332 - 0.3085 = 62.47%

b) For x > 30.2:

z = 30.2-28/2 = 1.1

From the normal distribution table, P(x > 30.2) = P(z > 1.1) = 1 - P(z > 1.1) = 1 - 0.8643 = 13.57%

The circumference of a circle is 212 inches What is the measurement of the diameter of the circle round your answer to the neare

Zepler [3.9K]

Hi there!
So first to find the diameter, you will need to find the radius of the circle because the diameter is twice the length of the radius.
Find the radius from the circumference, which is $2 \pi r$ .
C= $2 \pi r$
212= $2 \pi r$
212/ $2 \pi$ =r
Then solve for r.
Radius= 33.74
Then multiply the radius by 2 to find the diameter.
Diameter= 2 * 33.74
Diameter= 67.5 inches

Hope this helps :)

Answer:

∠A + ∠B = 90°

Step-by-step explanation:

Complementary angles are angles which, combined, add to 90°. Therefore, an equation displaying the relationship between two complementary angles may look like this: ∠A + ∠B = 90°.

Find the area. Use Pi = 3.14 a. 15.1976 cm2 c. 13.816 cm2 b. 6.908 cm2 d. 60.7904 cm2

amm1812

Answer:

Step-by-step explanation:

Diameter = 4.4 cm

Radius = 2.2 cm

Now

Area of the circle = πr²

= (3.14)(2.2)²

= (3.14)(4.84)

= 15.1976 cm²
