Answer:

$4.95

Step-by-step explanation:

Paul originally has $3.69.

His sister gives him $5.25.

$3.69 + $5.25 = $8.94

The CD single cost him $3.99

$8.94 - $3.99 = $4.95

Therefore, he has four dollars and 95 cents ($4.95) left.

Answer:

$4.95

Step-by-step explanation:

3.69+5.25= 8.94

8.94-3.99=4.95

Answer:

x= (1,8)

Step-by-step explanation:

Answer:

Step-by-step explanation:

-3≤ 6x - 9                 Add 9 to both sides

-3 + 9 ≤ 6x               Combine left

6 ≤ 6x                       Divide by 6

6/6 ≤ 6x/6

1 ≤ x

6x - 9 < 39               Add 9 to both sides

6x < 39 + 9              Combine

6x < 48                     Divide by 6

6x/6 < 48/6

x < 8

So the inequality is

1 ≤ x < 8

I think that is what you want. You have to express it as a combined inequality.

Answer:

Step-by-step explanation:

9) a = 2 ; b = 6

a) a + b =  2 + 6 = 8

b) b - a = 6 - 2 = 4

c) ab = 2 * 6 = 12

10) c = 12 ; d = 4

a) c ÷ d = 12 ÷ 4 = 3

b) c + d = 12 + 4 = 16

c) c - d = 12 - 4   = 8

Step-by-step explanation:

1. What is the standard deviation of the data set? Round to the nearest tenth if needed.

2, 4, 7, 8, 9

Answer: 2.9

2. Data Set A has a mean of 215 and a standard deviation of 35. Data Set B has a mean of 400 and a standard deviation of 12. Which data set is more spread out?

Answer: Data Set A

3. What is the standard deviation of a data set whose values are all the same?

Answer: 0

Answer:

y = a - k

Step-by-step explanation:

k = a - y

=> k + y = a

=> y = a - k

Step-by-step explanation:

[tex]8mn[/tex]

or equivalently

[tex]8\cdot m\cdot n[/tex]

We often write variable side-byside without the multiplication sign in algebra. It also applies to terms with indices. For instance,

[tex]\text{We write }a^2b^3c^4\text{ and mean }a^2\times b^3\times c^4[/tex]

We may, often also add a dot at the middle of both terms as another version of multiplication sign for better readability if the terms are more complicated, for instance

[tex]a\cdot b\cdot c[/tex]

and

[tex]\frac ab\cdot \sqrt{\frac{d^4}{b^9}}\cdot\pi[/tex]

Answer:

Step-by-step explanation:

So, to go about your question, we must first ask, how many hours a week is being worked?

In this problem, that is 9 hours per week.

Next, we must question how much per week is made

That is $92 per week

Finally, we must determine if the allowance is occuring many times in the week or just once.

In this problem, that is only occuring once for the week.

So, the equation we must setup is 9x +20 =92.

To solve the equation, we need to subtract 20 on both sides to isolate the variable, x.

9x+20=92

     -20     -20

Now our equation is

9x=72

Now, to finally get x by itself or to isolate x, you should divide 9 on both sides to cancel out the 9 being multiplied by the x.

9x=72

9     9

x=8 because of 72/9 is equal to 8.

I hope this helps, and I will answer any questions you have.

(7z + 5) + (2z - 1) + (6z + 3) + (3z - 9) =

Answer:

x = 12

Step-by-step explanation:

1 + 11 = 12, so x = 12. hope this helps

Answer:

A, (4,-3), (1, -1), (7,-6)

Step-by-step explanation:

f(x, y) = (y, -x) there is a 90° clockwise or 270° counterclockwise rotation

    To solve this problem form the system of equations as per statements given in the question then get the answer by solving them.

    Number of bushes in garden one were 55 and in second garden 11 originally.

   Let the number of raspberry bushes in one garden = x

And the number of raspberry bushes in second garden = y

So the equation for the given statement will be,

x = 5y -------(1)

Therefore, equation for this statement will be,

(x - 22) = (y + 22)

x - y = 22 + 22

x - y = 44 ------(2)

Substitute the value of x from equation (1) to equation (2)

5y - y = 44

4y = 44

y = 11

Substitute the value of 'y' in equation (1),

x = 5(11)

x = 55

                   Therefore, Number of bushes in garden one were 55 and in second garden 11 originally.

Answer:

Let first no. be x

Therefore,

2nd no. is x+1

Third no. is x+2

SUM OF NO.'s=x+x+1+x+2

Answer:

1/10

Step-by-step explanation:

8 black marbles, 5 white marbles and 12 red marbles = 25 marbles

P(red) = red/total = 12/25

Remove the marble

8 black marbles, 5 white marbles and 11 red marbles = 24 marbles

P(white) = white/total = 5/24

P(red, remove,white) = 12/25 * 5/24

                                   =12/24 * 5/25

                                   =1/2 * 1/5

                                   =1/10

Step-by-step explanation:

Total balls = 12 + 5 + 8 = 25 marbles

Probability of getting white marbles = 5/24

Probability of red marbles = 12/24 = 1/2

Now

Probability = 1/2 × 5/24 + 1

Probability = 1/2 × 5/25

Probability = 5/50

Probability = ⅒
