Answer 1

Answer:

34 hours

Step-by-step explanation:

Lets call M the number of hours that Maddie volunteered. Ryan volunteered 1 + 3×M hours, and altogether they volunteered 45 hours, so:

1 + 3×M + M = 45

1 + 4M = 45 Subtract 1 in both sides

4M = 44 Divide both sides by 4

M = 11 hours

So Maddie volunteered 11 hours, and Ryan volunteered

1 + 3×11 = 34 hours

The table shows the probability distribution of Pamela seeing red cars and green cars on her way to office.

Pamela can expect to see ___ red cars and___ green cars on her way to office.

Answers

The expected value of a dataset is the mean of the dataset.

The complete text is: Pamela can expect to see 1 red car and 1 green car on her way to office.

Expected value is calculated as:

[tex]\mathbf{E(x) =\sum x \times P(x)}[/tex]

For the red cars, we have:

[tex]\mathbf{Red = 0 \times 0.43 + 1 \times 0.31 + 2 \times 0.14 + 3 \times 0.10 + 4 \times 0.02}[/tex]

[tex]\mathbf{Red = 0.97}[/tex]

Approximate

[tex]\mathbf{Red = 1}[/tex]

For the green cars, we have:

[tex]\mathbf{Green= 0 \times 0.45 + 1 \times 0.17 + 2 \times 0.22 + 3 \times 0.07 + 4 \times 0.09}[/tex]

[tex]\mathbf{Green= 1.18}[/tex]

Approximate

[tex]\mathbf{Green= 1}[/tex]

Hence, the expected values of red and green is 1.

-3 1/3 x (-2 7/10)

Answers

Answer: 9

Step-by-step explanation:

-3 1/3 x (-2 7/10)

-3 = -3*(3/3) = -9/3

-3 1/3 = -10/3

(-2 7/10)

-2 = -2(10/10) = -20/10

-2 7/10 = -27/10

(-10/3)*(-27/10) = (270/30) = 9

Valeria has been training for the Charlestown cruisers bike race. The first week she trained, she rode 5 days and took the same two routes each day. She rode and 8 mile route each morning and longer route each evening. By the end of the week, she had ridden a total of 115 miles. How many miles did valeria ride each evening

Answers

The number of miles covered every evening obtujwd using a system of equation is 15 miles.

Let the number of miles per evening = m

Number of days = 5

Number of miles per morning = 8 miles

Total miles covered = 115 miles

Using the expression below :

Number of days(miles per morning + miles per evening) = 115 miles

5(8 + m) = 115

40 + 5m = 115

5m = 115 - 40

5m = 75

m = 75 / 5

m = 15 miles

Therefore, the Number of miles covered per evening is 15 miles.

What is the equation of the line that passes through the point (- 1, - 5) and has a slope of -1

Answers

Answer:

y = -x - 6

Step-by-step explanation:

Slope = m = -1

Equation of line: y = mx + b

y = - x + b

Plugin x = -1 and y = -5 in above equation

-5 = -(-1) + b

-5 = 1 + b

-5 - 1 = b

b = -6

Equation of the line: y = -x - 6

How do I find the variables here? ;-;

Answers

Answer:

y = 116

w = 116

x = 4

Step-by-step explanation:

a // b and t is transversal.

y + 64 = 180 {co-interior angles are supplementary}

y = 180- 64

y = 116

w = y {Alternate interior angles are equal}

w = 116

4x² = 64 {Alternate interior angles are equal}

x² = 64/4

x² = 16

x² = 4²

x = √(4*4)

x = 4

Izzati, Ai Ling, Rina and Susan share some stamps. Izzati and Ai ling take 1/4 and 1/8 of the total number of stamps respectively. After that, Rina takes 7/10 of the remaining stamps. Eventually, all the remaining stamps are taken by Susan. If Susan gets 42 stamps, find the total number of stamps originally.

Answers

Step-by-step explanation:

Assuming that the total stamp is x

According to the question

Izzati's stamps is 1/4

Ailing's number of stamps is 1/8

X= 1/4 x 1/8 = 5/8 - the remaining stamps.

Rina’s number of stamps is 7/10 x 5/8 = 35/80 x

5/8 x 35/80 = 15/80 - (Susan's stamps)

According to the question

15/80 = 42

X: 224

the total number of stamps originally is 224.
