Using the bar chart, what percent of the population studied has either 2 or 3 cars?
A) 22.7%
B) 34.0%
C) 43.3%
D) 71.0%

Answers

The percentage of the population studied with 2 or 3 cars represents the ratio of the number who has two or three cars to the total number of samples. Hence, the percent of the population is 71.0%

Total number of samples, T = (80+141+74+4+3+1)= 303Number with either 2 or 3 cars, n = (141 + 74) = 215

The percentage of the total sample with either 2 or 3 cars can be calculated thus :

(n ÷ T) × 100%

(215 ÷ 303) × 100%

0.7096 × 100%

= 70.96%

Therefore, 71% of the total population studied has either 2 or 3 cars.

Earth’s outer core can be modeled by a spherical shell that extends from a distance of approximately 1,200 kilometers from Earth’s center to approximately 3,400 kilometers from Earth’s center. Which of the following is closest to the volume of Earth’s outer core, in cubic kilometers?

Answers

Answer:

Explanation:

Volume of sphere= 3/4 [tex]\pi r3}[/tex]

(1200)+(3400)=4600⇒ diameter

4600/2=2300 kilometers

3/4×3.14×[tex]2300^{3}[/tex]=28,653,285,000 cubic kilometers

The answer is 28,653,285,000 cubic kilometers, I believe

The approximated volume of the Earth will be:

[tex]V =1.573*10^{11} km^3[/tex]

How to get the volume?

The volume can be modeled as the difference between the volume of a sphere with a radius of 3,400km and the volume of a sphere with a radius of 1,200 km.

Remember that the volume of a sphere of radius R is:

[tex]V = \frac{3}{4} *3.14*R^3[/tex]

Then the volume of Earth will be:

[tex]V = \frac{4}{3}*3.14*(3,400 km)^3 - \frac{4}{3}*3.14*(1,200 km)^3\\\\V = \frac{4}{3}*3.14*((3,400 km)^3 - (1,200 km)^3) = 1.573*10^{11} km^3[/tex]

The correct option is E: the relationship can be described as a "negative linear relationship with outliers".

It's negative because the values on the y axis is decreasing as they are increasing on the x axis. It's a linear relationship because you can easily draw a straight line of best fit through the scatter plot. There is an outlier on the top right corner of the graph.
