Answer:

670

Step-by-step explanation:

Answer:

a. -4 + 8p = 68

         8p = 68 + 4 = 72

           p = 72/8 = 9

a. is not the answer as the solution is not 8

b. 4 + 8p = 68

        8p = 68 - 4 = 64

         p = 64/8 = 8

b. is the answer as the solution is 8

c. 4 + -8p = 68

         -8p = 68 - 4 = 64

            p = 64/-8 = -8

c. is not the answer as the solution is not 8

d. 4 + 8p = -68

        8p = -68 -4 = -72

          p = -72/8 = -9

d. is not the answer as the solution is not 8

b. is the answer

Answer:

7.5 * 10^-4

Step-by-step explanation:

To express this, we will have to multiply 750 by the conversion unit

we have this as;

750 * 10^-6

750 = 7.5 * 10^2

so we have;

7.5 * 10^2 * 10^-6

= 7.5 * 10^(-6+2)

= 7.5 * 10^-4

The diameter of the bacterium in meters using scientific notation is 7.50 × 10^-4

Diameter of the bacterium in scientific notation = 7.50 × 10²

Recall one micrometer = 10^-6

So

7.50 × 10² × 10^-6

= 7.50 × 10^(2-6)

= 7.50 × 10^-4

The quadratic function R that correctly represents the revenue model is given by R(x) = -40x² + 640x.

To find the quadratic function R that represents the revenue, we need to multiply the ticket price x by the number of tickets sold Q(x).

Given that the number of tickets sold Q(x) is given by the linear function Q(x) = -40x + 640, the revenue R can be calculated as:

R(x) = x * Q(x)

Substitute the expression for Q(x) into the revenue equation:

R(x) = x * (-40x + 640)

Now, we'll expand the expression:

R(x) = -40x² + 640x

Thus, the quadratic function R that correctly represents the revenue model is given by R(x) = -40x² + 640x.

Answer:

pen = 2    book = 3

Step-by-step explanation:

p= pens

b=books

4p +3b =17

5p+2b=16

Multiply the first by 5

Multiply the second by -4

Add both (p variable will ce cancelled)

20p +15b = 85

-20p  -8b = -64

           7b = 21

              b=3        (book =3)

Lets plug this in one of the equations

4p + 3x3 = 17

4p +9 0 19

4p = 8

Answer:

Shaded region is 18.3 units²

Step-by-step explanation:

First find the area of the white triangle.  The base and height of this triangle are both 8.  Thus, the area of the triangle is (1/2)(base)(height), or 32 units.

Next, find the area of the whole circle.  It is πr², which in this case comes

out to π(8 units)² = 64π units².  Realize that (1/4) of this, or 16π units², is the area of the quarter circle that contains the triangle.

To find the shaded area, take the area of the quarter circle (16 π units²) and subtract the area of the triangle (32 units²).

16π units² - 32 units² = 18.3 units²

Shaded region is 18.3 units²

Answer:

n = 3

Step-by-step explanation:

Given

4n = 2n + 6 ( subtract 2n from both sides )

2n = 6 ( divide both sides by 2 )

n = 3

The solution is, n = 3.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

Given

4n = 2n + 6 ( subtract 2n from both sides )

2n = 6 ( divide both sides by 2 )

n = 3

Answer:

Answer: : g(x)=-sqrt(x+3)+8

Step-by-step explanation:

The function has the same range is the third one:

g(x)=-sqrt(x+3)+8

The range of this function is:

x+3>=0

sqrt(x+3)>=sqrt(0)

sqrt(x+3)>=0

Multiplying the equation by -1:

-1[ sqrt(x+3)>=0]

- sqrt(x+3)<=0

Adding 8 both sides of the equation:

- sqrt(x+3)+8<=0+8

- sqrt(x+3)+8<=8

g(x)<=8

Then Range g(x)= (-Infinite, 8]

Answer: Third option: g(x)=-sqrt(x+3)+8

Answer:

Obtuse angled triangle

Step-by-step explanation:

If a, b and c are the sides of a triangle with c the largest side

• If a² + b² = c² ⇒ right triangle

• If a² + b² > c² ⇒ acute angled

• If a² + b² < c² ⇒ obtuse angled

Here a = 8, b = 15, c = 23

a² + b² = 8² + 15² = 64 + 225 = 289

c² = 23² = 529

Since a² + b² < c² then obtuse angled triangle

Answer:

It's 108

You add the sides 48 and 24 and then subtract it from 180. That how you get your answer.

In this question, the points values are missing which is why its solution can be defined as follows:

Let

[tex]l= (7,-1) \\\\m=(-2, 4)\\\\n =(6,5)\\\\[/tex]

Formula:

[tex]d=\sqrt{((x_2-x_1)^2+(y_2-y_1)^2)}[/tex]

For d1:

[tex]x_1=7, y_1=-1, x_2=-2, y_2=4\\\\[/tex]

[tex]d=\sqrt{((-2-7)^2+(4+1)^2)}[/tex]

  [tex]=\sqrt{((-2-7)^2+(4+1)^2)}\\\\=\sqrt{((-9)^2+(5)^2)}\\\\=\sqrt{(81+25)}\\\\=\sqrt{(106)}\\\\=10.29[/tex]

For d2:

Answer: The sample portion would less closely model the population proportion

Answer:

Answer is that is will less closely model to the total population.

Step-by-step explanation:

This is because there are less numbers to be chosen and will be harder to find a proper medium and mean.

Answer:

(x, y) (1,5.5) , (2,5.75) (3,5.83) (4,5.875) (5,5.9)

Step-by-step explanation:

The x values lie on the horizontal line and the y values lie on the vertical line.

In order to find the value of y you must substitute the value of x in the equation given and you must plot you graph using the answers you got which I wrote for you.

Answer:

Normal distributions are symmetric around their mean. The mean, median, and mode of a normal distribution are equal. The area under the normal curve is equal to 1.0. Normal distributions are denser in the center and less dense in the tails.

Step-by-step explanation:

Extra Answered question:

How do you determine if a distribution is normal?

Answer: In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean. It must also adhere to the empirical rule that indicates the percentage of the data set that falls within (plus or minus) 1, 2 and 3 standard deviations of the mean.

I hope this is what your looking for :)

Answer:

I don't the right answers but I know these answers are incorrect:

The sample mean must  equal the population mean.

The standard deviation of the population must be less than 30.
