Answers
Answer:
10% of students buy neither the textbook nor the supplement from the bookstore
Step-by-step explanation:
We have that:
15% buy only the textbook.
75% buy both the textbook and the supplement.
None buy only the supplement.
a) What percent of students buy neither the textbook nor the supplement from the bookstore
15% + 75% = 90% buy at least one of them. So
100% - 90% = 10% buy neither.

Social scientists discovered that 1,013 General Social Survey (GSS) respondents in 2010 watched television for an average of 3.01 hours per day, with a standard deviation of 2.65 hours per day. Answer the following questions, assuming the distribution of the number of television hours is normal.
Required:
a. What is the Z score for a person who watches more than 8 hr/day?
b. What proportion of people watch television less than 5 hr/day? How many does this correspond to in the sample?
c. What number of television hours per day corresponds to a Z score of +1?
d. What is the percentage of people who watch between 1 and 6 hr television per day?
Answers
Answer:
Following are the responses to the given question:
Step-by-step explanation:
[tex]Sample \ size = n = 1013\\\\\mu = 3.01\\\\\sigma = 2.65[/tex]
For point a:
Using formula:
[tex]Z = \frac{(X - \mu)}{\sigma}\\\\X = 8\\\\Z = \frac{(8- 3.01)}{2.65} = 1.88\\\\[/tex]
For point b:
[tex]P(X<5)=?\\\\ x = 5\\\\ Z = \frac{(X - \mu)}{\sigma} = \frac{(5 -3.01)}{2.65} = 0.7509434\\\\P(Z< 0.7509434) = 0.7736566\\\\P(X<5) = P(Z< 0.7509434) = 0.7736566[/tex]
For point c:
[tex]X=? \\\\Z = 1\\\\\text{Formula for X score:}\\\\X = \mu + Z \times \alpha\\\\X = 3.01 + 1\times 2.65 = 3.01 + 2.65 = 5.66[/tex]
For point d:
[tex]P(1 \leq X \leq 6)=? \\\\P(1 \leq X \leq 6) = P(X \leq 6) - P(X\leq 1) = P(X< 6) - P(X<1)\\\\\text{Z score for x} = 6\\\\Z = \frac{(6 - 3.01)}{2.65} = 1.128301887 \\\\P(Z< 1.128301887) = 0.870403777 \\\\P(X<6) = P(Z< 1.128301887) = 0.870403777 \\\\\text{Z score for x} = 1 \\\\[/tex]
[tex]Z = \frac{(1 -3.01)}{2.65} = -0.758490566\\\\P(Z< -0.758490566) = 0.224078679\\\\P(X<1) = P(Z< -0.758490566) = 0.224078679 \\\\P(1 \leq X \leq 6) = P(X \leq 6) - P(X\leq 1) = P(X<6) - P(X<1) \\\\ = 0.870403777 - 0.224078679 = 0.646325097 \\\\\text{Required probability} = 0.646325097[/tex]

Answer:
A: 1 rectangle and 2 triangles (or 1 trapezoid and 1 triangle)
B: AB = 4; AE = 5
C: area = 34.5 square units
Step-by-step explanation:
Part AThe figure can be decomposed into a right trapezoid and a triangle. The right trapezoid can be decomposed into a rectangle and a triangle.
easiest decomposition: 1 right trapezoid and 1 triangle
decomposition per instructions: 1 rectangle and 2 triangles.
__
Part BAB is a horizontal line, so its length is the difference of the x-coordinates of B and A: 2 -(-2) = 4.
AE is a vertical line, so its length is the difference of the y-coordinates of A and E: 3 -(-2) = 5.
AB = 4, AE = 5
__
Part CThe area of the trapezoid is given by ...
A = 1/2(b1 +b2)h
The figure shows the base lengths to be 4 and 7, and the height to be 5. The trapezoid's area is ...
A = 1/2(4+7)(5) = 27.5 . . . . square units
The area of triangle CDE is given by the formula ...
A = 1/2bh
The figure shows the base length to be 7 and the height to be 2 units. The triangle area is ...
A = 1/2(7)(2) = 7 . . . . square units
The total area of figure ABCDE is 27.5 +7 = 34.5 square units.

The probability of not spinning a red, flipping tails, then not spinning an even number is ?
Answers
Answer:
2 / 9
Step-by-step explanation:
From the spinner :
Number of reds = 1
Total number of colors = 3
P(not red) = Probability of not spinning red, = 1 - p(red) = 1 - 1/3 = 2/3
P(flipping tail) = a coin flip, P(tail) = 1/2
P(not even) = probability of not obtaining an even number) = 1 - p(obtaining an even number)
(1, 2, 3) ; not even = (1, 3)
P(not even) = 2 /3
Compound probability = 2/3 * 1/2 * 2/3 = 4 / 18 = 2 /9

Indicate the measure of each angle when ∠PTS=128
Answers

Answer:
∠PTR = 80°
∠PTQ = 45°
∠QTS = 83°
Step-by-step explanation:
The outer scale is useful for reading the values of angles that start with PT.
∡PTR = 80°
∡PTQ = 45°
The measure of angle QTS is found from ...
∡PTS = ∡PTQ +∡QTS . . . . . angle sum theorem
∡QTS = ∡PTS -∡PTQ . . . . . subtract ∡PTQ
∡QTS = 128° -45°
∡QTS = 83°

Let the sequence be 1, 3, 5, 7, 9……… then this sequence is
Answers
the answer is 11 because 2 multiple are increasing
Answer:
An arithmetic sequence, The difference in any term with the previous term is same.
Step-by-step explanation:
See, ah this is a little bit easy question so let’s start solving it -:
Firstly, um see the difference between the given numbers-: 1, 3, 5, 7,9 _?
Between 1 and 3 the difference is 2
Between 5 and 3 the difference is 2
Between 7 and 5 the difference is 2
Between 9 and 7 the difference is 2
So, here we see the difference among all is same. So. it is an arithmetic sequence.
So, let's find the fourth term. We can either do it by arithmetic progression or by simply adding 2 to 7. I.ll first show you by doing A.P. then we will check the answer by adding 2 to 7.
So, as we know the basic formula of A.P. which is -: a1+(n-1)d
Here, a1=1, n=5, d=2
Let’s put the values in the formula-: 1+(5–1)2 = 1+(4)2 = 1+8 = 9
Now let’s check it. As the difference between each digit is same so definately the difference between 9 and the unknown number is 2.
Then, the unknown no. is 9+2 = 11
Hence, the answer is 11
