Answer:

Step-by-step explanation:

Select the correct answer from each drop-down menu.

We solve using z score formula

z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard deviation of 25 minutes.

a) The probability of a randomly selected student completing the test in 45 minutes or less is approximately equal to %.

z = 45 - 70/25

b) The probability of a randomly selected student completing the test in 95 minutes is %.

z = 95 - 70/25

Answer:

253

Step-by-step explanation:

Given

[tex]J = 9[/tex] --- Jenna's dog

[tex]A = 2277[/tex] -- Animal Shelter

See comment for proper format of the question

Required

How many times did A use than J

The options are not clear. So, the general solution is as follows.

To solve this, we simply divide the chew toys used in A by the chew toys used by J

So, we have:

[tex]n = \frac{A}{J}[/tex]

This gives:

[tex]n = \frac{2277}{9}[/tex]

[tex]n = 253[/tex]

Answer:

The value of x is [tex]\sqrt{113}[/tex].

Step-by-step explanation:

It is given that hypotenuse is [tex]\sqrt{177}[/tex]. So, the legs would be x and 8.

Let's use Pythagoras theorem,

[tex]a^{2} +b^{2} =c^{2}[/tex]

Plug in the numbers to solve for x.

[tex]x^{2} +8^{2} =\sqrt{177} ^{2}[/tex]

Simplify it

[tex]x^{2} +64 =177[/tex]

Subtract both sides 64.

[tex]x^{2} =113[/tex]

Take square root on both sides

x=[tex]\sqrt{113}[/tex]

We can not simplify the radical.

So, let's keep this as answer.

We will see that the percentage of the 60 children who choose orange is 25%.

In this case, the 60 children are the 100%.

We want to find which percentage 15 (number of kids that like orange) represents.

Then we can write:

15 = x

60 = 100%

x = (15/60)*100% = 25%

So we conclude that 25% of the children choose orange.

Step-by-step explanation:

We are told that the diameter of the red blood cell is 7 × 10^(-6) m

And that number of red blood cells in the person is; 2 × 10^(-13) red blood cells

Since they are held end to end, the length of the line would be;

7 × 10^(-6) × 2 × 10^(-13) = 14 × 10^(-19) m

Answer:

[tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]

Step-by-step explanation:

The equation of the curve is

[tex]Y = sin^{-1}(7x)[/tex]

To find the equation of tangent we need to differentiate this equation w.r.t x

So, differentiating we get

[tex]Y'=\frac{7}{\sqrt{1-49x^2} }[/tex]

This would give the slope of the tangent line at any given point of which x coordinate is known. In the present case it is  [tex]x = \sqrt{\frac{1}{7} }[/tex]

Then slope would accordingly be

[tex]Y'=\frac{7}{\sqrt{1-49/49} }[/tex]

= ∞

For, [tex]x = \sqrt{\frac{1}{7} }[/tex], [tex]Y = sin^{-1}(7/7)= \pi/2[/tex]

Equation of tangent line, in the point slope form, would be [tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]

"It is a repeated arrangement of numbers, shapes, colors and so on. "

For given question,

Charlotte the turtle was born with 4 squares on her shell, as in the first picture below.

When she was 1 year old, 12 new squares appeared around the old squares, as in the second picture below.

Each year, a new group of squares appeared around the old squares.

We find the same pattern to find the new squares appeared when she is 2 and 3 years old.

When she is 2 years old then the new squares appeared around the old squares, as shown below.

There are 20 new squares appeared around the old squares.

When she is 3 years old then the new squares appeared around the old squares, as shown below.

There are 28 new squares appeared around the old squares.

Therefore, when age is 2 then the new squares appeared = 20

when age is 3 then the new squares appeared = 28

broooooooooo why would it just be a mat nah it can be more smh

Answer:

6.16 hours

Step-by-step explanation:

Let the number of hours that washed the car together = T

Number of hours Matthew washed = m = 14 hours

Number of hours Arianna washed = a = 11 hours

The formula to calculate how many they wash the cars together is given as

1/a + 1/m = 1/T

1/14 + 1/11 = 1/T

Lowest Common Denominator = 154

Hence:

(11 + 14)/154 = 1/T

25/154 = 1/T

Cross Multiply

154 × 1 = 25 × T

T = 154/25

T = 6.16 hours

Therefore, it will take Matthew and Arianna 6.16 hours to wash the cars together

Answer:

below

Step-by-step explanation:

A)1 can be interpreted as the job, the project, the whole thing or all of the cars

B)rate* time = amount of work (a bit like rate*time = distance for figuring how far you go at a certain speed)

C)multiply both sides by 14 hours/1 job and simplify to get t=14hours

D) ok, now we do the 2nd fraction 1/11 we want its bottom to be 154, like: 1/14 - 11/11

E)t=154/25=t= 6.16 hours

The missing term is 20

Step-by-step explanation:

Given

[tex]f(x) = \frac{1}{2}x + 10[/tex]

[tex]h(x) = 2x -[/tex] --- inverse of f(x)

Required

Complete h(x)

We have:

[tex]f(x) = \frac{1}{2}x + 10[/tex]

Express f(x) as y

[tex]y = \frac{1}{2}x + 10[/tex]

Swap x and y

[tex]x = \frac{1}{2}y + 10[/tex]

Multiply through by 2

[tex]2x = y + 20[/tex]

Make y the subject

[tex]y = 2x - 20[/tex]

Replace y with the inverse function

[tex]h(x) = 2x - 20[/tex]

Compare

[tex]h(x) = 2x - 20[/tex]

with

[tex]h(x) = 2x -[/tex]

Answer:

76 degrees

Step-by-step explanation:

We know that supplementary angles equal 180 degrees. So, set up the equations:

[tex]180=(x+15)+(x-13)\\[/tex]

[tex]180=(2x+2)\\[/tex]

[tex]178=2x[/tex]

[tex]x=89\\[/tex]

Then, you just plug 89 back into ZB, and simplify:

[tex](89-13)\\[/tex]

[tex]=76[/tex]

So, the measurement of angle ZB is 76 degrees.
