3 0

Answer:

22 ft^2

Step-by-step explanation:

d of the cirlce=10 ft

Area of cirlce=pi(d^2)/4

=pi×(10^2)/4

=pi×(100)/4

p=pi×25

= Approximately, 78.539 ft^2

Length of square=10ft

Area of square=l^2

=10ft^2

=100 ft^2

Area of shaded portion=Area of square-Area of square

=100ft^2-78.539

=22 ft^2(closest given on the problem)

Determine the number of bytes in 513 BM
Naddik [55]
We know, 
    1 MB = 1000 KB
513 MB = (1,000 * 513) KB
             = 513,000 KB

Now,
          1 KB = 1,000 bytes
513,000 KB = (1,000 * 513,000) bytes
                   = 513,000,000 bytes 

∴ 513 MB is 513,000,000 bytes

Find the mean and the standard deviation for each set of values. Show your work. 15,17,19,20,14,23,12
vekshin1
1. Mean.

\overline{x}=\dfrac{15+17+19+20+14+23+12}{7}=\dfrac{120}{7}\approx\boxed{17.14}

2. <span>Standard deviation.

First we have to square each value and calculate the mean of that squares:

\overline{x^2}=\dfrac{15^2+17^2+19^2+20^2+14^2+23^2+12^2}{7}=\boxed{\dfrac{2144}{7}}

so the variance:

s^2=\overline{x^2}-\overline{x}^2=\dfrac{2144}{7}-\left(\dfrac{120}{7}\right)^2\approx\boxed{12.41}

and the standard deviation:

s=\sqrt{s^2}=\sqrt{12.41}\approx\boxed{3.52}
