Part A.
The venn diagram is attached. In the venn diagram, circle A represent the number of responds that have an ASU parking deal. Circle B represent the number of respondents that ride their bike to campus and circle C represent the number of respondents that that ride the Light Rail.
Part B.
From the venn diagram, the number of respondents that ride the Light Rail and ride their bike to campus is given by 39 –
12 = 27
Part C.
From the venn diagram, the number of respondents that only have an ASU parking decal is given by <span>77 –
12 – 8 – 6 = 51
Part D.
The number of respondents that ride the Light Rail or have an ASU decal is given by the sum of the number of respondents that ride the Light Rail only and those that have an ASU parking decal and those that have both ASU parking decal and ride their bike to school.
This is given by 51 + 8 + 28 = 87.
Part E.
The venn diagram showing the area </span><span>that represents people who have a parking decal or who ride their bike to campus but who do not ride the Light Rail</span> sgaded is attached.
QUESTION 1: To the nearest tenth, what is the area of a circle whose diameter is 21 inches? Use 3.14 for π. Enter your answer in the box.
The area of a circle given its diametrom by definition is:
A = pi * (d / 2) ^ 2
Substituting the value of the diameter we have and applying 3.14 for the value of pi, we have:
A = (3.14) * (21/2) ^ 2
A = 346.185
Round to the nearest tenth:
A = 346.2 in ^ 2
Answer:
The area of a circle whose diameter is 21 inches is:
A = 346.2 in ^ 2
QUESTION 2: What is the circumference of a circle with a radius of 5.4 inches?
Enter your answer as a decimal in the box. Use 3.14 for pi. Round your answer to the nearest tenth.
By definition, the circumference of a circle is given by:
C = 2 * pi * r
Where,
r : radius of the circumference
Substituting the values we have:
C = 2 * (3.14) * (5.4)
C = 33,912 in
Round to the nearest tenth:
C = 33.9 in
Answer:
The circumference of a circle with a radius of 5.4 inches is:
C = 33.9 in
QUESTION 3: A scale model of an ancient Egyptian pyramid is 29 centimeters high, with a base length of 46 centimeters. The height of the real pyramid is 145 meters. What is the base length of the real pyramid? Enter your answer, in simplest form, in the box.
The first thing we must do in this case is to find the scale factor.
For this we use the relationship between the heights.
We have then:
145 = k * 0.29
From here, let's clear k:
k = (145) / (0.29)
k = 500
We now apply the scale factor to find the actual length of the base:
b = k * 0.46
b = 500 * 0.46
b = 230 m
Answer:
The base length of the real pyramid is:
b = 230 m
QUESTION 4: Which expression is equivalent to 13 (4-5x-1)?
For this case what you should do is rewrite the expression:
13 ((4-1) -5x)
13 (3-5x)
Now we apply the commutative property:
39-65x
Answer:
An expression that is equivalent to 13 (4-5x-1) is:
39-65x
Answer:
p =
+ 2x - 5 + ![\frac{6}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7Bx%7D)
Step-by-step explanation:
divide each term by x and simplify
Answer:
You answer would be option B
Step-by-step explanation:
You would have to open parenthesis/distribute 4 by multiplying it by x and 8 which are inside the parenthesis.
