Answer:

68 miles

Step-by-step explanation:

Distance biked on the first five days =67,60 ,69 ,68 , and 70 miles

Let the distance biked on the sixth day=x miles

We want his average for the 6 days =67 miles per day

Therefore:

[tex]Average=\dfrac{67+60+69+68+70+x}{6} \\67=\dfrac{334+x}{6}\\$Cross multiply\\67*6=334+x\\402=334+x\\x=402-334\\x=68 miles[/tex]

He needs to bike 68 miles on the sixth day to get an average of 67 miles per day/

The greatest number of books by a student in this group is 15.

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

From the box plot,

We can see that,

Median = 6

First quartile = 2

Third quartile = 10

Smallest number = 2

Highest number = 15

Answer:

468 square feet; Option C

Step-by-step explanation:

We can see that the base of this triangular prism has dimensions 15 feet by 10 feet, so for starters let us compute the area of this base:

Area ⇒ 15 * 10 = 150 ft^2

Now the rectangular surface next to this base, has dimensions 9 feet by 10 feet, provided that 9 feet is a uniform height of the triangular prism:

Area ⇒ 9 * 10 = 90 ft^2

This third rectangle is provided with one dimensions, of 10 feet. If we were to imagine what part of the 3-d shape is is, it would in fact be the slanted top. To find the second dimension, you would imagine it to be 12 feet. Using that, the area of this rectangle is thus ⇒ 10 * 12 = 120 ft^2

Now the two triangles at the corners each have an area of ⇒ 1/2 * base * height = 1/2 * 12 * 9 = 6 * 9 = 54 ft^2, so they have a total area of ⇒ 108 ft^2

This means the surface area of the right, triangular prism is:

150 + 90 + 120 + 108 = Answer: 468 square feet

Step 1) Divide up the figure

In this figure, there is a triangle, a small rectangle, and two larger rectangles. The triangle is 6 in x 9 in, the small rectangle is 3 in x 18 in, one of the large rectangles (center) is 8 in x 14 in, and the other large rectangle (bottom) is 5 in x 9 in.

Step 2) Find the area of each shape in the figure

Triangle: A = 1/2 x 6 x 9 = 27

Small rectangle: A = 3 x 18 = 54

Large rectangle (center): A = 8 x 14 = 112

Large rectangle (bottom): A = 5 x 9 = 45

Step 3) Add the area of each shape together

A = 27 + 54 + 112 + 45 = 238 square inches

Hope this helps! :)

Answer:

247 square inches

Step-by-step explanation:

Divided the diagram into a triangle and three rectangles.

The triangle is 6 in * 6 in = 36 square inches

1st rectangle is 4 in * 3 in = 12 square inches

2nd rectangle is 11 in * 14 in = 154 square inches

3rd rectangle is 9 in * 5 in = 45 square inches

Therefore, 36+12+154+45 = 247 square inches

Answer:

5.18 pounds per square inch

Complete question:

If the pressure is 6 pounds per square inch when the temperature is 440° F,find  the pressure exerted when the temperature of the gas is 380°F.

Step-by-step explanation:

According to the Gay Lussac's Law:

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

where, P and T are the pressure and temperature of an enclosed ideal gas.

Given:

Initial pressure [tex]P_1[/tex] = 6 pounds per square inch

Initial Temperature [tex]T_1[/tex]=440° F

Final Temperature [tex]T_2[/tex]=380° F

Final Pressure [tex]P_2[/tex]=?

Substituting all values in the formula

[tex]\frac{6}{440} =\frac{P_2}{380}[/tex]

[tex]P_2[/tex] = [tex]\frac{6\times380}{440}[/tex]

[tex]P_2[/tex]= 5.18pounds per square inch

Answer:

39.10%

Step-by-step explanation:

The given timeout distributions are:

Exp (1/10), Exp (1/12)

The equation to use is the following:

F (x) = 1 - e ^ (- a / b); x> 0

So the probability is:

P (food has not arrived after waiting 25 minutes | R) = e ^ (- 10/10) = 0.3679

P (food has not arrived after waiting 25 minutes | S) = e ^ (- 12/15) = 0.2865

So:

P (food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) + (food has not arrived after waiting 25 minutes | S) * P (S)

Replacing:

P (food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 + 0.2865 * 2/3 = 0.3136

However:

P (R | food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) / P (food has not arrived after waiting 25 minutes)

P (R | food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 / 0.3136 = 0.3910

It means that the probability is 39.10%

Step-by-step explanation:

Answer:

The answer is 16/25

Step-by-step explanation:

Since the original scale factor was 4/5 then you would need to square four and five in order to get the new scale factor.

When you square 4 you get 16 and when you square 5 you get 25. Therefore the answer should be 16/25.

Answer:

60.63%

Step-by-step explanation:

Prob. of students who regularly attend = 45%

Prob. of students who don't attend = 55%

Upper Class Students who attend = 64 % of 45 %

= 0.64 × 0.45 × 100 = 28.8% = 0.288

Upper Class Students who don't attend = 34 % of 55% = 0.34 × 0.55 × 100 = 18.7% = 0.187

Total for Upper Class Students = 28.8% + 18.7% = 47.5% = 0.475

Probability that an Upper Class Student randomly selected will be attending = ( 0.288 / 0.475 ) × 100 = 0.6063 × 100 = 60.63%

Answer:

y=-5x+35

Step-by-step explanation:

The equation for a line in slope intercept form is y=mx+b, where m is the slope of the line and b is the y intercept, or where the line meets the y axis.

First, we should calculate the slope of the line. The slope of any line is rise over run. We can select any two points- I will select (6,5) and (4, 15).

We see that the rise is 10 units, because 15-5=10, and the run is -2 units, because 4-6=-2. We have rise over run which is 10/-2, or -5.

So, we find that the m value is equal to -5.

The y intercept is easier to find, it is just where the line meets the y axis. The lines meets the y axis at the point (0,35) so the y intercept is 35.

Thus we have the equation of the line is y=-5x+35.

Answer:

41/35

Step-by-step explanation:

Simplify the following:

4/7 + 3/5

Put 4/7 + 3/5 over the common denominator 35. 4/7 + 3/5 = (5×4)/35 + (7×3)/35:

(5×4)/35 + (7×3)/35

5×4 = 20:

20/35 + (7×3)/35

7×3 = 21:

20/35 + 21/35

20/35 + 21/35 = (20 + 21)/35:
