Answer:

The circumference is 24.69 in.

The area is 48.52 in.

Step-by-step explanation:

  • Circumference rule => Cf=2πr

So, Cf=2π(3.93)=24.69in

  • Area rule => A=πr^2

So, A=π(3.93)^2=48.52in

Fudgin [204]

Answer:

the x intercept is (0,100) and the y intercept is (0,0)

Step-by-step explanation:

g(x)=1/20x(x-100)

g(0)=1/20(0)(0-100)

g(0)=1/20*0(0-100)

g(0)=100

Just help, what are the answer, Its due in 15 minutes and yea, ill mark brainliest and dont give me a link saying the answer is
Naddik [55]

Answer:

<h2><u><em>6. </em></u></h2><h2><u><em>   a. 11 and 2/3 yds. squared</em></u></h2><h2 /><h2><u><em>   b. Yes, the volume of the shed is 11 and 1/3 yards squared and what she's trying to put into it is only 10 yards squared, if put in properly, it will be able to fit.</em></u></h2><h2 /><h2><u><em>7. 1,110 in. squared</em></u></h2>

Step-by-step explanation:

6.

a.

(10/3)*(14/9)*(9/4)

= 11 2/3

b.

Yes, because the volume of the shed is about 11.67 yards long, the 10 yards of wood will fit in the shed.

7.

For this one, we have to break it into two pieces.

(I made them into a small box and and big box)

The measurements of the small box are 7*5*6.

The measurements of the big box are 20*5*9.

Using this information, we can make the following equation and solve it quickly.

(7*5*6) + (20*5*9)

(210) + (900)

1,110

Thus, the volume of this box is 1,110 in. ^2

What is the mean absolute deviation for the set of data below?<br><br> 2, 8, 10, 16
Evgesh-ka [11]

Solution: We are given below data:

2, 8, 10, 16

Now to find the mean deviation, we use the below formula:

MD= \frac{\sum|X-\bar{X}|}{N}

Where:

\sum,  represents the summation

X, represents the observation.

\bar{X}, represents the mean

N represents the number of observation.

\bar{X}= \frac{\sum{X}}{N}= \frac{2+8+10+16}{4}=9

\sum |X-\bar{X}| = |2-9| + |8-9| +|10-9| +|16-9|=7+1+1+7=16

Therefore, the mean deviation is:

MD= \frac{16}{4}

        = 4
