A. 8pi B. pi C. 2pi D. 4pi

mestny [16]

Answer: Option C

$AC = 2\pi$

Step-by-step explanation:

The arc length is calculated as

$L = \theta * R$

Then

$AC = \theta * R$

We know that

$BC = 24\ ft$

If BC is the diameter of the circumference then the radius R is:

$R = \frac{BC}{2}$

$R = \frac{24}{2}$

$R = 12\ ft$

Now we convert the anglo from degrees to radians $\theta= 30\° * \frac{\pi}{180\°}\\\\\theta=\frac{1}{6}\pi$

Finally

$AC = \frac{1}{6}\pi * 12$

$AC = 2\pi$

amount spent on fruit/ total amount spent

He spent $18 on fruit, and $60 in total.

$18/ $60

Divide 18 by 60

18/60

Data Set #1

Harman [31]

Answer:

The data table is attached below.

Step-by-step explanation:

The average of a set of data is the value that is a representative of the entire data set.

The formula to compute averages is:

$\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}$

Compute the average for drop 1 as follows:

$\bar x_{1}=\frac{1}{3}\times[10+11+9]=10$

Compute the average for drop 2 as follows:

$\bar x_{2}=\frac{1}{3}\times[29+31+30]=30$

Compute the average for drop 3 as follows:

$\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33$

Compute the average for drop 4 as follows:

$\bar x_{4}=\frac{1}{3}\times[102+100+98]=100$

Compute the average for drop 5 as follows:

$\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67$

The data table is attached below.
