Answer:

2 and a half @ 2.5 inches (sorry i can't type the fraction)

Step-by-step explanation:

  • english is my second language so sorry if you doesn't understand:

(1/2, 1/4)=(x,y)

based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.

this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.

since the '5 months-hair-length' is above about 2 grid above 2 inch:

2 inch + 0.5 inch= 2.5 inch

In 2000, the population of a town was 8914. The population is expected to grow at a rate of 1.36% each year. What is the populat
Inga [223]

Answer:

9672

Step-by-step explanation:

Population growth can be represented by the equation A=A_0e^{rt}. We know the rate at which it grows is 1.36%. For the formula, we use the decimal conversion which is r=0.0136. We find the amount of time that has passed between 200 and 2006 is t=6 years. In this context, the starting population is A_0=8914. We substitute and solve for A.

A=A_0e^{rt}\\A=8914e^{0.0136(6))}

A=8914e^{0.0816}[

We solve with a calculator by evaluating the exponent first and then multiplying by 8914.

A=8914e^{0.0816}[ .

A=8914(1.08502171433)[

The solution is 9671.88356154 but we round to 9672.

frozen [14]

Answer:

96π

Step-by-step explanation:

You will need the formula for the volume of a cone.

V=\frac{1}{3}πr^{2}h

r= 6 cm

To find the height, you need to use the Pythagorean theorem.

a²+ b² = c² (a and b are the 2 legs and c is the hypotenuse)

b = \sqrt{{c^{2}-a^{2} }

b= \sqrt{10^{2}-6^{2}  } = 8

h= 8 cm

remember PEMDAS!

V=\frac{1}{3}π(6)^{2}8

V=\frac{1}{3}π(36)8

V= π(12)8

V= 96π

Answering in terms of π is more accurate because it is actually infinite so when it gets rounded to 3.14, that is only an approximation of pi. (π is actually 3.1415926535897932384626433 etc.)

The descriptive statistics are shown.
Cloud [144]

The median is always at the center of the box, we can say the median of our question is also at the middle of the box.

<h3>What is a graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The description of the measures given has been done below and also what they indicate about the shape of the box and whisker plot have been given.

From the given data we see that;

Mean = 39,500

Median = 20000

Mode = 23000

Minimum = 15,000

Maximum = 255000

A general view of a box and whisker plot has been attached.

From the attached file, we can see the following;

- whiskers to the left and right of the box.

- The box starts from the lower quartile and stops at the upper quartile.

- The median is at the middle of the box

- The minimum is at the end of the left whisker

- The maximum is at the end of the right whisker.

1) Now, since median is always at the center of the box, we can say the median of our question is also at the middle of the box.

2) The median is 20000 but the minimum which is the end of the left whisker is 15000 while the maximum which is the end of the right whisker is 255000. This means the minimum is very close to the median and as such the left whisker would be very short. In contrast, the right whisker will be very long since the maximum is far larger than the median.

3) Since the right whisker is far larger than the left whisker, then we can say the shape of the box and whisker plot is heavily skewed to the right.
