Answer:

173,380

Step-by-step explanation:

just took the test and got it right

The expected cost of raising a child is $173,380.

Given,

C = 2.32 N + 34,180.

C represents the cost of raising a child.

N represents the income.

If the Murphy family has an annual income of $60,000.

We are to find the expected cost of raising a child using the given equation.

We have,

C = 2.32 N + 34,180________(A)

Now,

If the Murphy family has an annual income of $60,000.

N = $60,000___________(B)

Putting (B) in (A).

C = 2.32 x $60,000 + 34,180

C = 139,200 + 34,180

C = $173,380.

Thus the expected cost of raising a child is $173,380.

Answer: 40 units

Step-by-step explanation:

(7,3) (12,3) on the same y coordinate, 5 squares apart

(12,3) (12,11) on the same x coordinate, 8 squares apart

8 × 5 = 40

The area of a rectangle with vertices at (7,3), (12,3), (12, 11), and (7,11) is 40 square unit.

A brace of figures called equals are used to detect a point or a form in a two- dimensional aeroplane . Thex-coordinate and the y- match are two figures that define a point's position on a 2D aeroplane .

We have vertices of rectangle as

vertices at (7,3), (12,3), (12, 11), and (7, 11).

Now, the coordinates (7,3) and (12,3) have the same y coordinate  also the difference in x match is 5 places piecemeal.

and, (12,3) and (12,11) have the same x coordinate then the difference in y coordinate is 8 squares apart.

So, the Area of rectangle

= 8 × 5

= 40 square unit

Answer:

[tex]x = \frac{23}{22} [/tex]

Step-by-step explanation:

[tex]22x = 23 \\ \frac{22x}{22} = \frac{23}{22} \\ x = \frac{23}{22} [/tex]

Answer:

x = 23/22 = 1.045

Step-by-step explanation:

Solving a Single Variable Equation :

1.1      Solve  :    22x-23 = 0

Add  23  to both sides of the equation :

                     22x = 23

Divide both sides of the equation by 22:

                    x = 23/22 = 1.045

Answer:

The answer is 457

Step-by-step explanation:

You set up an equation as

10a+7c=6459

a+c=783

c= child

a= adult

then you simplify to 3a=978 by taking out one of the values.  You get a - 326.

783-326=457 so there is your answer

4x+3=3(x+3)

4x+3=3x+9

4x-3x=9-3

Step-by-step explanation:

It's a reflection of it's self, so the only reasonable answer would be the the letter of the copied image of itself.

Think about it like a mirror. One side is what you see, but what is facing it is the original, so if the original is C then its copy is G.

Translation I believe , because reflecting would have the P upside down and that’s not represented

Answer:

First option

Step-by-step explanation:

There is a mistake in the description of the first function.  

On a coordinate plane, a straight line with a positive slope crosses the x-axis at (-6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (-4, 1), (0, 3).

Given two points of a function, (x1, y1) and (x2, y2), its rate of change between them is:

Rate of change: (y2 - y1)/(x2 - x1)

Points of the 1st graph: (-4, 1), (0, 3).

Rate of change: (3- 1)/(0 - (-4)) = 1/2

Points of the 2nd graph: (-4, 1), (0, -3).

Rate of change: (-3 - 1)/(0 - (-4)) = -1

Points of the 3rd graph: (-4, 0), (0, 4).

Rate of change: (4 - 0)/(0 - (-4)) = 1

Points of the 4th graph: (-4, 0.25), (0, 4).

Rate of change: (4 - 0.25)/(0 - (-4))   = 0.9375

Answer:

87% would be faster than 58 seconds

Step-by-step explanation:

Landon runs the 400 meter dash, his finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second

[tex]\mu = 60[/tex]

Standard deviation =[tex]\sigma = 1[/tex]

We are supposed to find Landon were to 38 practice trials of the 400 meter dash , how many of those trials would be faster than 58 seconds , to the nearest whole number i.eP(x<58)

[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{58-60}{1}\\Z=-2[/tex]

Refer the z table for p value

P(x<58)=0.0228

Landon were to 38 practice trials

So, P(x<58)=[tex]38 \times 0.0228=0.8664[/tex]

So, 86.64%  would be faster than 58 seconds

Hence 87% would be faster than 58 seconds

percentage change   ≈  140%

Step-by-step explanation:

There were 144 people in attendance at the school football game last Friday. This week there were 346 people in attendance at the school football game.What is the percent of change from last week to this week?Round your answer to the nearest whole number

To calculate the percentage change, we will follow the steps below:

First, we will find the difference(that is increase) between 144 and 346

Increase = New  number - Original number

             = 346 - 144

              = 202

Next is to divide the increase which is 202 by the original  number which is 144  and then multiply by 100

That is;

percentage change = increase ÷ original number × 100

                                   =202 / 144   ×  100

                                   ≈ 140    to the nearest  whole number

percentage change   ≈  140 %

Step-by-step explanation:

Total fruits = 7+ 4 = 11

Probability of apples = 7/ 11

The probability of the apples should be [tex]7\div 11[/tex]

Since A basket contains seven apples and four peaches. You randomly select a piece of fruit and then return it to the basket.

So here the total fruits should be

= 7 + 4

= 11

Now the probability of the apple should be [tex]7\div 11[/tex]

hence, we can conclude that The probability of the apples should be [tex]7\div 11[/tex]
