Which histogram correctly displays the information above
Answer: The answer is c
Dr. Victory is a psychologist studying the effects of high-level classes, bullying, and music classes on the anxiety levels of middle school students. He has previously determined that the effects from class levels, bullying experiences, and music classes are independent. It has been determined that the probability that a student is taking a high-level English class is 0.23, the probability that a student has been bullied is 0.36, and 1/3 of students are in music classes.
(a) What is the probability that a randomly selected student is in a high-level English class and has been bullied?
(b) What is the probability that a randomly selected student is in a music class and has been bullied?
(c) What is the probability that a randomly selected student is in a music class, has been bullied, and is in a high-level English class?
Answer:
a) 0.0828 = 8.28% probability that a randomly selected student is in a high-level English class and has been bullied
b) 0.12 = 12% probability that a randomly selected student is in a music class and has been bullied
c) 0.0276 = 2.76% probability that a randomly selected student is in a music class, has been bullied, and is in a high-level English class
Step-by-step explanation:
Probabilities of independent events happening together:
The probabilities of independent events happening together is the multiplication of the probabilities of each event happening.
In this question:
0.23 probability that a student is taking a high-level English class.
0.36 probability that a student has been bullied.
1/3 = 0.3333 probability that a student is in music class.
(a) What is the probability that a randomly selected student is in a high-level English class and has been bullied?
0.23*0.36 = 0.0828
0.0828 = 8.28% probability that a randomly selected student is in a high-level English class and has been bullied
(b) What is the probability that a randomly selected student is in a music class and has been bullied?
0.36*1/3 = 0.12
0.12 = 12% probability that a randomly selected student is in a music class and has been bullied
(c) What is the probability that a randomly selected student is in a music class, has been bullied, and is in a high-level English class?
0.23*0.36*1/3 = 0.23*0.12 = 0.0276
0.0276 = 2.76% probability that a randomly selected student is in a music class, has been bullied, and is in a high-level English class

12. Find the Volume of the rectangular prism below. Write your final answer as a decimal by converting the fraction to decimal. Also write the units as cubic inches. * 13 in. 2 in. 3 in
Answer:
V = 9.75 cubic inches.
Step-by-step explanation:
Given the following data;
Length = 2 inches
Width = 3¼ inches
Height = 1½ inches
To find the volume of rectangular prism;
Volume of rectangular prism = length * width * height
V = 2 * 3¼ * 1½
V = 2 * 13/4 * 3/2
V = 2 * 39/8
V = 2 * 4.875
V = 9.75 cubic inches
I need the surface area plz
Answer:
922
Step-by-step explanation:
(5x22)x2=220
(13x5)x2=130
(22x13)x2=572
220+130+572=922
Answer:
Length (l) = 22 ft
Breadth (b) = 13 ft
Height (h) = 5 ft
Surface Area of a cuboid
[tex] = 2(lb + bh + lh)[/tex]
[tex] = 2(22 \times 13 + 13 \times 5 + 5 \times 22) \\ = 2(286 + 65 + 110) \\ = 2(461) \\ = 2 \times 461 \\ = 922 \: ft ^{3} [/tex]
=> Surface area of the cuboid will be 922 ft³.

Give your answer in index form.
b) Work out the Highest Common Factor of 375 and 150.
Answer:
a) 375 = 3 × 3 × 3× 3 × 5
in index form it is 3 × 5³.
prime factor of,
150 = 2 × 3 × 5 × 5.

Find the surface area of the rectangular prism:
Answer: 430 cm²
Step-by-step explanation:
1) Front x Back= 15 x 7 x 2= 210 (We do time 2 because there are two of the same shapes ex. there are two squares that are both 16 ft so just do 16 x 2)
2) Right x Left= 7 x 5 x 2 = 70
3) Top x Bottom= 15 x 5 x2 = 150
4) Add. 150 + 210 + 70 = 430 cm²

the sum of 2 numbers is 56.twice the smaller number exceeds one-half the larger number by 22.find the numbers
9514 1404 393Answer:
20, 36
Step-by-step explanation:
Let x and y represent the smaller and larger numbers, respectively. The given relations let us write two equations:
x + y = 56 . . . . . . the sum of the two numbers is 56
2x -y/2 = 22 . . . . twice the smaller exceeds half the larger by 22
We can solve this by multiplying the second equation by 2 and adding the first.
2(2x -y/2) +(x +y) = 2(22) +56
5x = 100 . . . . . . simplify
x = 20
y = 56 -20 = 36
The two numbers are 20 and 36.

Graph triangle JKL and its image after a reflection in the line x=2 J(1,-1), K(3,0), L(0,-4)
Answer:

Step-by-step explanation:
The points after image reflection in the line x = 2 will be k'(1, 0), L'(4, -4) and J'(3, -1).
What is a graph?In math, graph science is the theory of geometric structures called graphs that are used to represent pairwise different objects. Vertices—also known as nodes or points—that are joined by edges make form a network in this sense.
Undirected graphs, where edges connect two vertices equally, and focused therapy, where edges connect two vertices unevenly, are distinguished.
As per the given information in the question,
Here mirror (x = 2) is vertical, hence only x-coordinate changes vertical distance from x-axis will not change.
For point k(3, 0)
It is one unit right side or x = 2. So, its image point will be one unit left side that is k'(1, 0).
For point L(0, -4)
It is two unit left side, so L' will be 2 unit right side of x = 2, so the point will be L'(4, -4)
Similarly, point J(1, -1) will become J'(3, -1).
