Answer: 20%

Step-by-step explanation: The same number applies here. Think about it this way, let's say you have a friend named Sofia and she has 3 dollars more than you, how many dollars do you have less than Sofia? 3 dollars. That's the easiest way I can explain it.

Weights of female cats of a certain breed are normally distributed with mean 4.1 kg and standard deviation 0.6 kg.
Diano4ka-milaya [45]
The proportion is 0.4401.

We find z-scores that correspond with both ends of this interval.  Z-scores are given using the formula:

z=\frac{X-\mu}{\sigma}

For the lower end, 

z=\fracc{3.7-4.1}{0.6}=\frac{-0.4}{0.6}=-0.67

The proportion of scores to the left of this number is 0.2514.

For the higher end, the z-score is

z=\frac{4.4-4.1}{0.6}=\frac{0.3}{0.6}=0.5

The proportion of scores to the left of this number is 0.6915.

To find just the proportion of scores between these two, we subtract;

0.6915-0.2514 = 0.4401.

A contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across. How many square
SOVA2 [1]

Answer:

A. 346.19 square feet.

Step-by-step explanation:

We have been given that a contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across.

To find the square feet of flooring required, we will find area of circle.

Since the length across the circle is 21 feet, so radius of circle will be half of 21 feet.

\text{Radius}=\frac{\text{21 feet}}{2}

\text{Radius}=\text{10.5 feet}

\text{Area of circle}=\pi r^2

\text{Area of circle}=\pi (\text{10.5 feet})^2

\text{Area of circle}=3.14*110.25\text{ feet}^2

\text{Area of circle}=346.185\text{ feet}^2

\text{Area of circle}\approx 346.19\text{ feet}^2

Therefore, 346.19 square feet of flooring will be required.
