A student surveyed 100 students and determined the number of students who take statistics or calculus among seniors and juniors. Here are the results.
Let A be the event that the student takes statistics and B be the event that the student is a senior.
What is P(A and B)?
A. 0.15
B. 0.33
C. 0.47
D. 0.68
Pr ( A & B ) , ie Probability (Senior Student with Statistics) = 0.15
Given : Event A = Student is senior, Event B = Student takes statistics
Total Students = Seniors with Statistics + Juniors with Statistics + Seniors with Calculus + Juniors with Calculus = 15 + 18 + 35 + 32 = 100 students Pr (A & B) , ie Probability (Senior Student with Statistics) = 15 studentsPr (A & B) = Favourable Students / Total Students = 15 / 100
P = 0.15

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 9 inches. The height of the cone is 18 inches.
Use pi = 3.14.
What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.
Answer:
We can say that volume of cylinder (452.16) is greater than volume of cone (301.44).
Step-by-step explanation:
Diameter of cylinder = 8 inches
Diameter of cone = 8 inches
Height of cylinder = 9 inches
Height of cone = 18 inches
We need to find the relationship between the volume of this cylinder and this cone.
First we will find volume of the cylinder
The formula used is: [tex]Volume=\pi r^2h[/tex]
We have
Diameter of cylinder = 8 inches
Radius = d/2 = 8/2 = 4 inches.
Height of cylinder = 9 inches
Putting values and finding volume
[tex]Volume=\pi r^2h\\Volume=3.14\times (4)^2 \times 9\\Volume=452.16[/tex]
So, Volume of cylinder = 452.16 inches³
Now, we will find volume of the cone
The formula used is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]
We have
Diameter of cone = 8 inches
Radius = d/2 = 8/2 = 4 inches.
Height of cone = 9 inches
Putting values and finding volume
[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14 \times (4)^2 \times \frac{18}{3}\\Volume=3.14 \times (4)^2 \times 6\\Volume=301.44[/tex]
So, Volume of cone = 301.44 inches³
Now, comparing volume of both cylinder and cone.
Volume of cylinder = 452.16 inches³
Volume of cone = 301.44 inches³
We can say that volume of cylinder (452.16) is greater than volume of cone (301.44).

4 The triangles shown are similar. Find y.
180 degrees is equal to a triangle if we add 111 and 32 degrees it will get 143 degrees so we should subtract 143 from 180 degrees it will get 37
the formula for the sum of the degree measures of the interior angles of a polygon is S=180(n-2) Solve for ,n, the number of sides of the polygon, in terms of S
NEED STEP BY STEP EXPLANATION
Answer:
n = (S + 360)/180Step-by-step explanation:
Given formula:
S = 180(n - 2)Solving for n:
S = 180(n - 2) ⇒ open parenthesisS = 180n - 360 ⇒ isolate n180n = S + 360 ⇒ divide both sides by 180n = (S + 360)/180[tex]S = 180(n - 2) \\ S = 180n - 360 \\ 180n =( S + 360) \\ n = \frac{(S+ 360)}{180} [/tex]
where, n =number of sides of polygon
S =sum of the degree measures of the interior angles of the polygon

Answer: x=68
Step-by-step explanation:
A. It’s asking what the last test must have to be (x) for all five tests to average out to an 80. This can be represent by:
(95+76+77+84+x)/5=80
The first four numbers are the existing test scores and x is the score you need. This is all divided by five so that you can find the average of all of these added together, which will equal 80, because that’s the grade you’re trying to get. Next, just solve for x:
= 95+76+77+84+x=80(5)
= 332+x=400
X=68
B. I got 74 for this one by using the same process as in part a, but I divided the left side by six and multiplied x by two: (95+76+77+84+2x)/6=80
But I’m not completely positive about this answer. A is definitely right though

Answer:
Option C
Step-by-step explanation:
Given expression is [tex]y^{-\frac{4}{3}}[/tex].
Exponent of this expression is [tex](-\frac{4}{3})[/tex].
Option (A)
[tex]-\frac{4}{3}y[/tex]
Since, exponents and coefficients of both the expressions are different.
They are not equivalent.
Option (B)
[tex]-(\sqrt[3]{y})^4=-(y^{\frac{1}{3}})^4[/tex]
[tex]=-y^{\frac{4}{3}}[/tex]
Here, exponent is with positive notation [tex](+\frac{4}{3})[/tex] while in the original expression it is negative [tex](-\frac{4}{3})[/tex].
Therefore, both the expressions are not equivalent.
Option (C)
[tex]\frac{1}{(\sqrt[3]{y})^4}=(\sqrt[3]{y})^{-4}[/tex]
[tex]=y^{-\frac{4}{3}}[/tex]
Both the expressions are equivalent.
Option (D)
[tex]-(\sqrt[4]{y})^3=-(y)^{\frac{3}{4}}[/tex]
Exponents of both the expressions are different.
Therefore, not equivalent.
Option (E)
[tex]\frac{1}{(\sqrt[4]{x})^3}=(\sqrt[4]{x})^{-3}[/tex]
[tex]=y^{-\frac{3}{4}}[/tex]
Exponent of this expression is different from the original expression.
Therefore, not equivalent.
Option (C) will be the correct option.
One equation in a system of equations is y=4x-5 write a second equation to complete the system if the solution to the system is (3,7) PLSSS BE QUICK :))
Answer:
4y = -x + 31
Step-by-step explanation:
Given that one equation in a system of equations is y = 4x - 5 write a second equation to complete the system if the solution to the system is (3,7)
Since the solution of the system is (3, 7), that means the two lines of equations meet or intersect at point X = 3 and Y = 7
Let assume that the two equations are perpendicular to each other. Then, there slope can be expressed as
M1M2 = -1
Where M1 = 4
Find M2
4M2 = -1
M2 = -1 / 4
Using general linear equation
Y = MX + C
Let's find C by substituting Y, X and M2
7 = -1 /4( 3 ) + C
7 = -3/4 + C
C = 7 + 3/4
C = 31/4
Substitute C back into the equation
Y = -1/4X + 31/4
4y = -x + 31
Therefore, the second equation is
4y = -x + 31

What is 1200% as a simplified fraction>
Answer:
Step 1: Write down the percent divided by 100 like this: 1200% = 1200 / 100. Step 2: Multiply both top and bottom by 10 for every number after the decimal point: As 1200 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

The perimeter of a rectangle is 12x + 4. If the width is 2x,
the length of the rectangle is
Answer:
4x+2
Step-by-step explanation:
Perimeter = 2(width) + 2(length). So 12x+4 = 2(2x) + 2(length) .
12x+4 = 4x + 2(length) then subtract 4x from both sides to get 8x+4 = 2(length). In order to get length by itself you need to divide both side by 2.
4x+2 = length. Hope this helps!
