Answer:

11.76

Step-by-step explanation:

We are given that,

Total number of students = 340

Students that prefer cheese pizza = 40

Students that prefer pepperoni pizza = 28

Thus, we get that,

The proportion of students that prefers cheese pizza =

i.e. The proportion of the students preferring cheese pizza = 0.1176 = 11.76%

Hence, 11.76% of the students prefer cheese pizza.

Answer:

P(Snickers n Snickers)  = [tex]\frac{2}{51}[/tex]

Step-by-step explanation:

Given

Bag of candy

5 Reese's Peanut Butter Cups,

4 Snickers

3 Sour Patch

6 Skittles

Required

Calculate P(Snickers n Snickers)

To solve this question, it'll be assumed that you and your friend selected snickers at a consecutive time.

First, we need to calculate the total number of candy

Total = 5 + 4 + 3 + 6

Total = 18 candies

P(Snickers n Snickers) means P(Snickers and Snickers);

i.e. the probability of selecting snicker twice

Number of snickers = 4;

So, the probability of you selecting a snicker first is [tex]\frac{4}{18}[/tex]

This is gotten by dividing number of snickers by total candies.

At this point, there are 4 - 1 snickers left and there are 18 - 1 candies left;

So, the probability of your friend selecting a snicker is [tex]\frac{4 - 1}{18 - 1}[/tex].

So, P(Snickers n Snickers)  = [tex]\frac{4}{18}[/tex] * [tex]\frac{4 - 1}{18 - 1}[/tex]

P(Snickers n Snickers)  = [tex]\frac{4}{18}[/tex] * [tex]\frac{3}{17}[/tex]

P(Snickers n Snickers)  = [tex]\frac{2}{9}[/tex] * [tex]\frac{3}{17}[/tex]

P(Snickers n Snickers)  = [tex]\frac{2}{3}[/tex] * [tex]\frac{1}{17}[/tex]

P(Snickers n Snickers)  = [tex]\frac{2}{51}[/tex]

Hence, the probability of you and your friend choosing snickers is [tex]\frac{2}{51}[/tex]

Answer:

y = 40.

Step-by-step explanation:

The opposite sides of a cyclic quadrilateral sum to 180, so:

3y + 2y - 20 = 180

5y = 180 + 20 = 200

y = 40.

Answer:

[tex]Area=45\pi$ square inches[/tex]

Step-by-step explanation:

The radius, r of the expanding circle of oil is modeled by the function:

[tex]r(s)=3\sqrt{s}[/tex], where s is time in seconds.

When s=5

Area of a circle[tex]=\pi r^2[/tex]

Therefore, area of the oil spill when s=5 seconds is:

[tex]Area=\pi (3\sqrt{5})^2\\=\pi *3^2*(\sqrt{5})^2\\=\pi *9*5\\$Area=45\pi$ square inches[/tex]

The area of the spill when s=5 seconds is 45pi square inches.

Answer:

(m-16)(m+4)

Step-by-step explanation:

To factor a quadratic expression

First write the variable in each parentheses, then put negative/ positive, after that ask yourself what numbers have the product of the coefficient of x^0 and the sum of x^1.

David correctly factored the expression m^2 - 12m - 64 and got (m - 16)(m + 4).

An equation can be factored into its factors by splitting the middle term of the equation.

m^2 - 12m - 64 = 0

⇒ m^2 - 16m +4m - 64 = 0

⇒ m(m - 16) + 4(m - 16) = 0

⇒ (m + 4)(m - 16) = 0

The factors of the equation m^2 - 12m - 64 = 0 are (m - 16)(m + 4).

Therefore, we have found that David correctly factored the expression m^2 - 12m - 64 and got (m - 16)(m + 4). The correct answer is option C or (3).

Answer:

3.625

Step-by-step explanation:

Line segment IK = 35.

This is a parallelogram, in which:

LJ is a line bisector of IK; line Imidpoint = line segment kmidpoint.

IK = (4x + 3) + (4x + 3)

35 = (4x + 3) + (4x + 3)

Simplify. Combine like terms:

35 = 8x + 6

Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS =

Parenthesis

Exponents & Roots

Multiplication

Division

Addition

Subtraction.

First, subtract 6 from both sides:

35 (-6) = 8x + 6 (-6)

35 - 6 = 8x

29 = 8x

Divide 8 from both sides:

(29)/8 = (8x)/8

x = 29/8

x = 3.625

3.625 is your answer.

Answer:

X= 8

The reason why X equals 8 is because the gave you the measurement of points I and K. They have created an expression to find points I and K and all they ask you to do is find the value of x.

To find the value of x, think about the measurement of points I and K. The measurements of point I and K equals 35. So we have to substitute a number for x that would make the expression equal 35. This is how I did it, so I thought 4 times what would get me close to 35. Then 4*8 came to my head and that automatically equals 32 and then when you add the three you get 35!
