g(x) = 2x – 4
h(x)=x²-3
Find (g.h)(5)

Answers

Answer:

40

Step-by-step explanation:

This is asking you to plug in the value of h(5) into g(x). First solve for h(5)

x^2-3 = h(x)

5^2-3= 22

h(5) = 22

h(5) is 22. So now, plug that into g(x).

g(h(5)) = 2(22)-4

44-4=40

(g.h)(5) is 40.

In a large city school system with 20 elementary schools, the school board is considering the adoption of a new policy that would require elementary students to pass a test in order to be promoted to the next grade. The PTA wants to find out whether parents agree with this plan.

A statistics teacher wants to see if there is any difference in the abilities of students enrolled in statistics today and those enrolled five years ago. A sample of final examination scores from students enrolled today and from students enrolled five years ago was taken. You are given the following results. T
oday 5 Years Ago Mean 82 88 Variance 112.5 54 Sample Size 45 36
The standard deviation of the difference between the means of the two populations is
A) 12.9
B) 9.3
C) 4
D) 2

Answers

Answer: D) 2

Step-by-step explanation:

The standard deviation of the difference between the means of the two populations is given by:-

[tex]S.E.=\sqrt{\dfrac{\sigma^2_1}{n_1}+\dfrac{\sigma^2_2}{n_2}}}[/tex]

where [tex]n_1[/tex]= sample size of population 1

[tex]n_2[/tex]= sample size of population 2

[tex]\sigma^2_1[/tex]= variance of population 1

[tex]\sigma^2_2[/tex]= variance of population 2

As per given,

[tex]S.E.=\sqrt{\dfrac{112.5}{45}+\dfrac{54}{36}}}\\\\=\sqrt{4}\\=2[/tex]

Hence, the correct option is D) 2.

You borrow $600 to buy a canoe. The simple annual interest rate is 5%. You pay off the loan after 4 years of equal monthly payments. How much is each payment?

Answers

Answer:

Amount of each payment = $15 each month

Step-by-step explanation:

Given:

Amount borrow = $600

Simple rate = 5% = 0.05

Number of year = 4 year

Payment method = monthly payment

Find:

Amount of each payment

Computation:

Total amount after 4 year = P + PRT

Total amount after 4 year = 600 + (600)(4)(0.05)

Total amount after 4 year = 600 + 120

Total amount after 4 year = $720

Number of total month = 4 x 12

Number of total month = 48

Amount of each payment = Total amount after 4 year / Number of total month

Amount of each payment = $720 / 48

Amount of each payment = $15 each month

Answer:

Okay so for this one use the Pythagorean theorem

Step-by-step explanation:

A^2 + 28^2 = 128^2

You are trying to find A.

So 28^2 is 784

128^2 is 16384

Now you will subtract 784 from both sides of the equation your new equation should be this: a^2 = 15600

Now you find the square root of both sides which gives you: A= 124.89 round it to 125

Answer:

Step-by-step explanation:

Some useful relations are ...

  A triangle inscribed in a semicircle is a right triangle.

  Acute angles in a right triangle are complementary.

  An inscribed angle is half the measure of the arc it intercepts.

  The sum of arcs around a circle is 360°; 180° around a semicircle.

__

1. Arc DF is twice the marked inscribed angle, so is 126°. Arc FE is supplementary to that, so is ...

  arc FE = 180° -126°

  arc FE = 54°

Alternate solution: arc FE is twice angle D, which is the complement of 63°.

  2(90° -63°) = 2(27°) = 54° = arc FE

__

2. Arc GJ = 360°-68° -31° -115° = 146°

  angle GHJ = angle GIJ = 146°/2 = 73°

__

3. arc UT = 2(90° -43°) = 94°

  9x -14 = 94

  9x = 108 . . . . . add 14

Answer:

y = x

Step-by-step explanation:

Hi,

We know that in the equation...

y = mx + b

m = slope

So, to find the equation of the line, we have to plug in what we already know. So...

-7 = 1 (-7) + b

Solve...

-7 = -7 + b

b = 0

That means that your equation is...

y = x

(you don't have to put the one in front of the x)

I hope this helps :)

y = mx + b
The m represents your slope.
y = (1)x + b
You can now plug in your coordinate points.
-7 = -7 + b
You will notice that they are equal to each other, which means b can only equal zero.
The equation will be...
y = x + 0
or
y = x

You need a 90% alcohol solution. On hand, you have a 55 mL of a 45% alcohol mixture. You also have 95% alcohol mixture. How much of the 95% mixture will you need to add to obtain the desired solution?

Answers

Answer:

495 milliliters of the 95% mixture are needed.

Step-by-step explanation:

Given that I need a 90% alcohol solution, and on hand I have a 55 ml of a 45% alcohol mixture, and I also have 95% alcohol mixture, to determine how much of the 95% mixture will I need to add to obtain the desired solution, the following calculation must be performed:

55 x 0.45 + 45 x 0.95 = 67.5

25 x 0.45 + 75 x 0.95 = 82.5

15 x 0.45 + 85 x 0.95 = 87.5

10 x 0.45 + 90 x 0.95 = 90

10 = 55

90 = X

90 x 55/10 = X

4,950 / 10 = X

495 = X

Thus, 495 milliliters of the 95% mixture are needed.
