Avery guessed that the typical number of sit-ups her classmates could do was 30 in 1 minute. Avery tested this idea by recording

VashaNatasha [74]

Answer:

1. What is the most common number of sit-ups completed in 1 minute? Explain how you used the dot plot to identify this number.

A: On the chart the number 38 has the most plotted dots.

2. What is the spread of this data set

A: 34 - 42

3. According to this data set, is Avery's guess of 30 sit-ups per minute too low, too high, or about right? Explain.

A: 30 is a little too low, the lowest count on the chart is 34, and Avery's estimate was 30, meaning its too low.

Randy is starting a beehive so that he can have fresh honey. He decides to check the current population of bees in the hive by m

satela [25.4K]

Answer:

Best estimate for the bee population is 1280.

Step-by-step explanation:

Randy marked total number of bees = 160

Then he collected 240 bees and observed that number of bees marked

= 30

We have to find the total population of the bee or best estimate for the bee population.

Now we use the ratio of marked bees in the sample vs marked bees in the total population

$\frac{\text{Number of bees marked in the sample}}{\text{Total bees in the sample taken}}=\frac{\text{Number of bees marked in total population}}{\text{Number of bees in the hive}}$ $\frac{30}{240}=\frac{160}{x}$

x = $\frac{160\times 240}{30}=1280$

Therefore, the best estimate for the bee population is 1280.

Find the surface area of a sphere that has a volume of 288 cu. in.

LenKa [72]

The formula of a volume of a sphere:

$V=\dfrac{4}{3}\pi R^3$

R - radius

We have the volume = 288 in³. Substitute:

$\dfrac{4}{3}\pi R^3=288\qquad\text{multiply both sides by 3}\\\\4\pi R^3=864\qquad\text{divide both sides by}\ 4\pi\\\\R^3=\dfrac{216}{\pi}\to R=\sqrt[3]{\dfrac{216}{\pi}}\\\\R=\dfrac{\sqrt[3]{216}}{\sqrt[3]{\pi}}\\\\R=\dfrac{6}{\sqrt[3]{\pi}}\ in$

The formula of a surface area of a sphere:

$S.A.=4\pi R^2$

Substitute:

$S.A.=4\pi\left(\dfrac{6}{\sqrt[3]{\pi}}\right)^2=4\pi\cdot\dfrac{6^2}{\sqrt[3]{\pi^2}}=\dfrac{4\pi\cdot36}{\sqrt[3]{\pi^2}}=\dfrac{144\pi}{\sqrt[3]{\pi^2}}\\\\S.A.=\dfrac{144\pi}{\sqrt[3]{\pi^2}}\cdot\dfrac{\sqrt[3]{\pi}}{\sqrt[3]{\pi}}=\dfrac{144\pi\sqrt[3]{\pi}}{\sqrt[3]{\pi^3}}=\dfrac{144\pi\sqrt[3]{\pi}}{\pi}=\boxed{144\sqrt[3]{\pi}\ in^2}$
