Which expression is equivalent to √100 ?

Sketch the area under the standard normal curve over the indicated interval and find the specified area. (Round your answer to f

Paraphin [41]

Answer:

Step-by-step explanation:

The normal distribution curve standard is bell shaped having mean =0 and std devition =1.

This is symmetrical about the y axis i.e. mean. More than 99% of the area under the curve lie between z=-3 to z=3

To find the area to the right of z =0.05 is equivalent to

calculating the

Probability that Z >0.05

= P(Z>0.05)

=0.5-0.0199

=0.4801

It takes your garden hose 20 seconds to fill your 2-gallon watering can. How long will it take to fill a circular inflatable poo

Naddik [55]

Answer:

It will take ≈ 8.27 hours to fill the circular inflatable pool using the garden hose

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Time it takes your garden hose to fill a 2-gallon watering can = 20 seconds

Circular inflatable pool size = 13 feet in diameter and 3 feet deep

2. How long will it take to fill a circular inflatable pool?

A. For answering the question, the first step is to calculate the volume of the inflatable pool, this way:

Diameter = 13 feet ⇒ Radius = 6.5 feet

Height = 3 feet

Volume of the inflatable pool = π * r² * h

Replacing with the real values, we have:

Volume of the inflatable pool = 3.1416 * 6.5² * 3

Volume of the inflatable pool = 398.2 feet³

B. Now we need to calculate how much water in gallons the inflatable pool will hold, this way:

Volume of the inflatable pool in gallons = Volume of the inflatable pool in cubic feet * 7.48

Replacing with the real values, we have:

Volume of the inflatable pool in gallons = 398.2 * 7.48

Volume of the inflatable pool in gallons = 2,978.54

C. Finally, we need to calculate the time it will take to fill the pool using the garden hose, this way:

Time it takes your garden hose to fill a 2-gallon watering can = 20 seconds

Simplifying, we have:

Time it takes your garden hose to fill a 1-gallon watering can = 10 seconds

Time it will take to fill the pool with the garden hose = Volume of the inflatable pool in gallons * 10

Replacing with the real values, we have:

Time it will take to fill the pool with the garden hose = 2,978.54 * 10

Time it will take to fill the pool with the garden hose = 29,785.4 seconds or 8.27 hours

It will take ≈ 8.27 hours to fill the circular inflatable pool using the garden hose

Farmer Bill sold potatoes at the farm market. He sold a quarter to the first person, 4/9 of what was left to the second person,

Lelu [443]

Answer:

Farmer Bill sold 120 lb of potatoes

Step-by-step explanation:

Suppose farmer Bill had x lb of potatoes. He sold a quarter to the first person. A quarter is written as (1/4)x. After that, Bill had x-(1/4)x = (3/4)x.

Then he sold 4/9 of what was left to the second person, thus it was left 1-4/9=5/9 of the remaining potatoes. Multiplying both factors:

$\frac{5}{9}*\frac{3}{4}x=\frac{5}{12}x$

This is the remaining portion of the potatoes.

Finally, he sold 4/5 of it and the last 10 lb. This means 1 - 4/5 = 1/5 of the remaining is equivalent to 10 lb:

$\frac{1}{5}*\frac{5}{12}x=\frac{1}{12}x$

Thus:

$\frac{1}{12}x=10$

x = 120 lb
