Answer:

The answer would be blonde and black.

Step-by-step explanation:

This would be because on the chart they are shown as the mayority of the class.

The expected value based on the probability will be 3/7.

Landing on the blue sector will give 3 points = 3/7    points

Landing on a yellow sector will give 1 point = 2/7  points

Landing on a purple sector will give 0 points = 0 points

Landing on a red sector will give –1 point.  = -2/7 points

The expected value will be:

=  3/7 + 2/7 + 0 - 2/7

= 3/7

The change to the values assigned to outcomes to make the game fair is to make 3.5 points for landing on the blue sector.

Answer:

3 11/20 miles

Step-by-step explanation:

Monday = seven -quarters of a mile

= 7/4 miles

Tuesday = nine-fifths of a mile

= 9/5 miles

How many miles did she ride altogether?

Total miles she rode altogether = Monday + Tuesday

= 7/4 + 9/5

= (35+36)/20

= 71/20

= 3 11/20

Total miles she rode altogether = 3 11/20 miles

Answer:

we have

when

base=8cm

height=11cm

area of parallelogram is :base×height

=8*11=88cm³

Now for

base=15cm

height=h

we have

the area of parallelogram=88cm²

base ×height=88cm²

15*h=88

h=88/15

h=88/15 or 5 13/15 or 5.86 cm in approximately

Given parameters :

To find :

Solution :

We know that area of a parallelogram is base inti height .

In case 1 take the base as 8 cm and height as 11 cm

In second case take the base as 15 cm and the height as h cm .

Note that we are doing this in the same figure so the area would be same .

The solution is, the letters in the word GRADE can be arranged in 120 ways.

In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.

here, we have,

Given that we are to evaluate the number of ways to arrange the letters in the word GRADE,

In the word GRADE, we have 5 distinct letters:

G(1), R(2), A(3), D(4), E(5).

There are 5 letters.

Thus, the number of ways of arranging the letters is evaluated as

5! = 1×2×3×4×5

   =120

Hence, the letters in the word GRADE can be arranged in 120 ways.

Answer:

y = -1

Step-by-step explanation:

I'll solve for "y" since there is no "x"

First expand the numbers inside the parenthesis by multiplying -4

-4y  + 8 =12

Subtract 8 from both sides to isolate -4y

-4y = 4

divide both sides by -4 to get "y"

y= -1

Answer:

Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:

P is the price of the cake

S is the number of servings

Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)

In turn, 10 is the fixed cost of each cake.

There are 21 black socks and 9 white socks. Theoretically, the probability of picking a black sock is 21/(21+9) = 21/30 = 0.70 = 70%

Assuming we select any given sock, and then put it back (or replace it with an identical copy), then we should expect about 0.70*10 = 7 black socks out of the 10 we pick from the drawer. If no replacement is made, then the expected sock count will likely be different.

The dot plot shows the data set is

{5, 5, 6, 6, 7, 7, 7, 8, 8, 8}

The middle-most value is between the first two '7's, so the median is (7+7)/2 = 14/2 = 7. This can be thought of as the average expected number of black socks to get based on this simulation. So that's why I consider it a fair number generator because it matches fairly closely with the theoretical expected number of black socks we should get. Again, this is all based on us replacing each sock after a selection is made.

Answer:

A. 30,000 square inches

Step-by-step explanation:

multiply the dimensions by 80

1 7/8 x 80 = 150

2 1/2 x 80 = 200

find the area

200 x 150 = 30000 [tex]in^2[/tex]

Answer:

A or C or b

Step-by-step explanation:

1 7/8+1 7/8= 2 14/8

2 1/2 + 2 1/2= 5

1 14/8 + 5= 6 14/8

[14/8 = 14÷8=

8×1=8

14-8=6]

6 6/8= 6.8

6 is related to 3 and eight

8 is related to 4 and 2

Answer:

1) -2x-12

2) 9x-14

Step-by-step explanation:

1). We use distributive property. We have to multiply -2 by x and 6. This means that the expression is -2x-12.

2). We use the distributive property again. We have to multiply -4 by 6 and x. Therefore, the equation will be 10-24+4x+5x. Then, we have to combine like terms. 10-24 is equal to -14 and 4x+5x is equal to 9x. Therefore, it is equal to 9x-14.
