HELP PLEASE!!! Math question

Answers

Answer 1

Answer:

(a). [tex]\frac{3}{7}[/tex]

(b). [tex]\frac{4}{13}[/tex]

Step-by-step explanation:

(a). Odds in favor of winning a new T.V. = [tex]\frac{4}{7}[/tex]

Or probability of not winning a new T.V. = [tex]\frac{4}{7}[/tex]

Since, Probability to win a T.V. + Probability of not winning the new T.V. = 1

Probability of winning a new T.V. = 1 - Probability of not winning a new T.V.

= 1 - [tex]\frac{4}{7}[/tex]

= [tex]\frac{7-4}{7}[/tex]

= [tex]\frac{3}{7}[/tex]

(b). Probability of winning the match + probability of not winning the match = 1

[tex]\frac{9}{13}[/tex] + Probability of not winning the match = 1

Probability of not winning the match = 1 - [tex]\frac{9}{13}[/tex]

= [tex]\frac{13-9}{13}[/tex]

= [tex]\frac{4}{13}[/tex]

A box of cereal states that there 99 calories in a 3/4 cup serving. What is the unit rate for calories per cup how many calories are there in 2 cups of the cereal

Answers

Answer

The unit rate should be 132 cal, and the total cal in 2 cups should be 264.

Step-by-step explanation

How you will get the unit rate is by multiplying 99 cal by 4 then dividing that amount by 3 to get 132. After that you can multiply 3 into that to get 264

Answer:

We conclude that for 1/2 batch, Faird would require 3/8 cups of sugar.

Step-by-step explanation:

Suger needed for a full batch = 3/4Given that Farid is making 1/2 of batch

We need to determine the expression for the amount of sugar Freed needs to make 1/2 batch.

Let 'x' be the batch and 'y' be the amount of sugar

Suger needed for a full batch = 3/4 cup of a sugar

x = 3/4y

But, Farid is making 1/2 of the batch.

Thus, multiply both sides by 1/2

[tex]x\times \frac{1}{2}\:=\:\frac{3}{4}y\times \frac{1}{2}[/tex]

[tex]\frac{x}{2}=\frac{3y}{8}[/tex]

Therefore, we conclude that for 1/2 batch, Faird would require 3/8 cups of sugar.

Answers

Answer:

Y = 130

X = 20

Z = 110

Answer:

y= 130 degrees x= 20 degrees z= 110 degrees

Step-by-step explanation:

I solved top left triangle first. So, we know all triangles add up to 180 degrees and we have two on the angles so 85 + 45 = 130 then 180 - 130 = 50 so the missing angle near y is 50. Now to figure out Y then you just subract your answer (50) from 180 which you get 130. So y is 130 degrees. Then to figure out X, you just do 180 - 130 = 50, 50 - 30 = 20, so x is equal to 20 degrees. Then lastly to figure out z we know that the missing angle is 50 because its vertical to the other 50 degree so now you do 180 - 20 = 160, 160 - 50 = 110 degrees.

Which expression can be used to find The amount of money for camp leader spends on b books

Answers

Answer:

Part A: A. 7.50 x b

Part B: $90

Step-by-step explanation:

Part A: The cost of a book is $7.50, so the equation that is going to tell you the total cost of however many books purchased is equation A.

Part B: $90. If the cost of a book is $7.50 and the teacher purchases 12 books, you do $7.50 x 12= $90. You can check the equation by adding $7.50 12 times. You will get the same result.

−6x + 6y = 6 −6x + 3y = −12

Answers

Answer:

x = 0

y = 2

Step-by-step explanation:

−6x + 6y = 6 −6x + 3y = −12

-6x+6x+6y-3y = 6

3y = 6

y = 2

checking:

6-6x+3.2 = -12

6-6x+6 = -12

12-6x = 12

x = 0

checking 2:

since x = 0 we ignore it and its multipliers from the equation:

6y=6+3y = 12

6.2 = 12 (check)

6+3.2 = 12

6+6 = 12 (check)

A parabola can be drawn given a focus of (-4, -5) and a directrix of y=3. Write the equation of the parabola in any form.

Answers

Answer:

The equation of the parabola is (x + 4)² = -16(y + 1)

Step-by-step explanation:

The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where

The vertex of the parabola is (h, k)The focus is (h, k + p)The directrix is at y = k - p

∵ The focus at (-4, -5)

∴ h = -4

∴ k + p = -5 ⇒ (1)

∵ The directrix at y = 3

∴ k - p = 3 ⇒ (2)

→ Add equations (1) and (2) to find k

∴ 2k = -2

→ Divide both sides by 2 to find k

∴ k = -1

→ Substitute it in equation (1) to find p

∵ -1 + p = -5

→ Add both sides by 1

∴ -1 + 1 + p = -5 + 1

∴ p = -4

→ Substitute the values of h, k, and p in the formula above

∵ (x - -4)² = 4(-4)(y - -1)

∴ (x + 4)² = -16(y + 1)

∴ The equation of the parabola is (x + 4)² = -16(y + 1)

Answer:

P(A∩B) = 0.12

Step-by-step explanation:

Given:

Students receive financial aid P(A) = 40% = 0.4

Students receive financial aid and first generation P(B/A) = 30% = 0.3

Find:

Probability [Selected student receives financial aid and is first generation college student] P(A∩B)

Computation:

P(A∩B) = P(A) x P(B/A)

P(A∩B) = 0.4 x 0.3
