Answer:

B. Yes! Jason has printed 73/100 of the posters needed.

Step-by-step explanation:

7/10(1500) = 1050 minimum to print

1500-400 = 1100 printed

1100/1500 = 73/100

Answer:

[tex]f^{-1}[/tex](x)=2x+10

Step-by-step explanation:

f(x)=[tex]\frac{x}{2}[/tex]-5

Let y= [tex]\frac{x}{2}[/tex]-5

y= [tex]\frac{y}{2}[/tex]-5

x+5= [tex]\frac{y}{2}[/tex]

Both side multiple 2,

2x+10=y

[tex]f^{-1}[/tex](x)=2x+10

Answer:

[tex]Probability = \frac{243}{1024}[/tex]

Step-by-step explanation:

Given

[tex]Sum = \{7, 11, 12\}[/tex]

[tex]Rolls = 5[/tex]

Required

Probability of not getting audited

If a pair of dice is rolled, the following are the observations of the sum

[tex]Outcomes = 36[/tex]

[tex]Sum\ of\ 7 = 6[/tex]

[tex]Sum\ of\ 11 = 2[/tex]

[tex]Sum\ of\ 12 = 1[/tex]

So, in a single roll; The probability of getting audited is:

[tex]p= \frac{1 + 2 + 6}{36}[/tex]

[tex]p= \frac{9}{36}[/tex]

[tex]p= \frac{1}{4}[/tex]

The probability of not getting audited in a single roll is:

[tex]q = 1 - p[/tex] --- Complement rule

[tex]q = 1 - \frac{1}{4}[/tex]

Take LCM

[tex]q = \frac{4 - 1}{4}[/tex]

[tex]q = \frac{3}{4}[/tex]

The probability of not getting audited in 5 rolls is:

[tex]Probability = q^5[/tex]

[tex]Probability = (\frac{3}{4})^5[/tex]

[tex]Probability = \frac{3^5}{4^5}[/tex]

[tex]Probability = \frac{243}{1024}[/tex]

ima answer it but first how do i show the work

Step-by-step explanation:

Answer:

(-6, 6)

x=-6, y=6

Step-by-step explanation:

The easiest way to solve for this is by substitution. This means substituting y with -5x-24 in the first equation. It gives you the same variables and is easy to work with.

1. Set up your equation: -7x-4(-5x-24)=18

2. Use the distribution property: -7x+20x+96=18

3. Add like terms: 13x+96=18

4. Subtract 96 from both sides: 13x=-78

5. Divide by 13 to get x alone: x=-6

Now that we have x, we can find y much easier by plugging in -6 for x.

1. Set up your equation: -5(-6)-24=y

2. Multiply: 30-24=y

3. Subtract: 6=y

Check your answers!

-7(-6)-4(6)=18

-5(-6)-24=6

There you go! Hope this helped :)

Step-by-step explanation:

Answer:

50% of the applicants will be hired.

Step-by-step explanation:

Given that four people applied for a job as an assistant manager at a store, but only two of these people will be hired, the following calculation must be performed to determine the percentage of people who will enter the job:

4 - 2 = 2

4 = 100

2 = X

2 x 100/4 = X

200/4 = X

50 = X

Thus, 50% of the applicants will enter the job.

Answer:

the book has 40 pages

Step-by-step explanation:

so he has read 90 percent and has 4 pages left. So 10 percent is 4 pages.

10 times 10 is 100. 4 times 10 is 40. The entire book is 40 pages.

10 percent equals 4 pages

20 percent percent 8 pages

30 percent  is 12 pages

40 percent is 16 pages

50 percent is 20 pages

60 percent is 24 pages

70 percent is 28 pages

80 percent is 32 pages

90 percent is 36 pages

100 percent is 40 pages

Answer:

3200 ft-lb

Step-by-step explanation:

To answer this question, we need to find the force applied by the rope on the bucket at time [tex]t[/tex]

At [tex]t=0, the weight of the bucket is 6+36=42 \mathrm{lb}[/tex]

After [tex]t[/tex] seconds, the weight of the bucket is [tex]42-0.15 t \mathrm{lb}[/tex]

Since the acceleration of the bucket is the force on the bucket by the rope is equal to the weight of the bucket.

If the upward direction is positive, the displacement after [tex]t[/tex] seconds is [tex]x=1.5 t[/tex]

Since the well is 80 ft deep, the time to pull out the bucket is [tex]\frac{80}{2}=40 \mathrm{~s}[/tex]

We are now ready to calculate the work done by the rope on the bucket.

Since the displacement and the force are in the same direction, we can write

[tex]W=\int_{t=0}^{t=36} F d x[/tex]

Use [tex]x=1.5 t[/tex] and [tex]F=42-0.15 t[/tex]

[tex]W=\int_{0}^{36}(42-0.15 t)(1.5 d t)[/tex]

[tex]=\int_{0}^{36} 63-0.225 t d t[/tex]

[tex]=63 \cdot 36-0.2 \cdot 36^{2}-0=3200 \mathrm{ft} \cdot \mathrm{lb}[/tex]

[tex]=\left[63 t-0.2 t^{2}\right]_{0}^{36}[/tex]

[tex]W=3200 \mathrm{ft} \cdot \mathrm{lb}[/tex]

Answer:

Answer:

A bit of a doosy, but bare with me: f*g*h(x) = [tex]x^2+54x-12x\sqrt{x} -108\sqrt{x} +90[/tex]

Step-by-step explanation:

So explaining this is a bit awkward as well, but I can try...So

Starting from g(x) working that backwards into f(x), so...

g(x) = [tex]x-3[/tex]

f(x) = [tex](x^4+9)[/tex]

Take your g(x) and plug it into your f(x) into every x you see

f(g(x)) = [tex](x-3)^4+9[/tex] ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...

Now you still have one more step which you still need to include h(x), so

Remember h(x) = [tex]\sqrt{x}[/tex]

Now plug in your h(x) into every x you see from f(g(x)) and it should look like...

[tex](\sqrt{x} -3)^4 + 9[/tex]

Answer:

The rate of change is 10%

Step-by-step explanation:

The computation of the rate of change is as follows:

Given that as on Jan 15, the snow pack is 150 inches

And, the last year, it would decrease by 11 inches a week after jan 15

So, the rate of change is

= 15 ÷ 150

= 10%

Answer:

No mode ???? I'm not sure

Answer:

A = 76

Step-by-step explanation:

Formula of the area of a triangle: [tex]A=\frac{h*b}{2}[/tex]

Formula of a rectangle: [tex]A=l*w[/tex]

So starting with the triangle...You know that the height of the triangle is 7, and the base of the triangle is 8 because the base of the rectangle is the same as the triangle's base...

Now using the formula of the triangle...

A = [tex]\frac{7*8}{2}[/tex]

= 28

Now find the area of the whole retangle...The length of the rectangle is 13 because 7+6=13; the width is 8

Now using the formula of the rectangle...

A = [tex]13*8[/tex]

= 108

Now that you have the areas of both the triangle and the retangle...Do subtraction to find the shaded area...

[tex]108 - 28 = 76[/tex]

Answer:

82.5 is the right answer

Answer:

3 with the exponent on 4 and 9 with the exponent of 2 have the same value

Answer:

here's your solution

=> percent means divided by 100

=> to find 40% of a number ,

=> we have to think for a number here it

is not given

=> so, we have to assume it , then let the

number be X

=> now ,. equation= 40/100*x

=> 40/100*X

hope it helps
