Answer:

After expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get  [tex]3c^3-16c^2-24c-8[/tex]

Step-by-step explanation:

We need to expand the polynomial [tex](3c + 2)(c^2-6c-4)[/tex]

Multiply the terms:

[tex](3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8[/tex]

So, after expanding the polynomial [tex](3c + 2)(c^2-6c-4)[/tex] we get  [tex]3c^3-16c^2-24c-8[/tex]

Complete Question

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 143 millimetres, and a standard deviation of 5. If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimetres? Round your answer to four decimal places.

Answer:

The probability is [tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  47

    The mean diameter is [tex]\mu = 143[/tex]

    The standard deviation is [tex]\sigma = 5[/tex]

Generally the standard error of the mean is mathematically represented as

       [tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>     [tex]\sigma_{x} = \frac{5 }{\sqrt{47} }[/tex]

=>     [tex]\sigma_{x} = 0.7293[/tex]

Generally the probability that the sample mean will differ from the population mean by more than 0.2 milli meters is mathematically represented as

       [tex]P(|\= x - \mu | \ge 0.2 ) = P(\frac{|\= x - \mu|}{\sigma_{x}} \ge \frac{0.2}{0.7293} )[/tex]

[tex]\frac{|\= x - \mu | -\mu}{\sigma }  =  |Z| (The  \ standardized \  value\  of  \ {|\= x - \mu |  )[/tex]

=>      [tex]P(|\= x - \mu | \ge 0.2 ) = P(|Z| \ge 0.2742 )[/tex]

=>     [tex]P(|\= x - \mu | \ge 0.2 ) = P(Z < - 2742) + P(Z > 0.2742)[/tex]

From the z table  the area under the normal curve to the left corresponding to   -2.742  is

    [tex]P(Z < -0.2742) =0.39197[/tex]

From the z table  the area under the normal curve to the right corresponding to   2.742  is        

    P(Z > 0.2742)   =  0.39197

So

      [tex]P(|\= x - \mu | \ge 0.2 ) = 0.39197 + 0.39197[/tex]

      [tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]

Answer:

Answer:

they cost the same after 2 months

Step-by-step explanation:

Since we're looking for these two gyms cost the same, we need to make the equation compare the two together:

35x + 80 = 75x (the 1st gym with a joining fee $80 and 35 monthly equals $75 monthly)

Subtract 35x from both sides:

35x - 35x + 80 = 75x - 35x

80 = 40x

Divide by 40:

80 / 40 = 40x / 40

2 = x

So they cost the same after 2 months

35 * 2 + 80 = 75 * 2

150 = 150

And you'll be spending $150 in total.

Step-by-step explanation:

The solution for the system of equations → y = 3x + 1  and

4x - 3y = -13 is (2, 7)

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is the system of equations as -

y = 3x + 1

AND

4x - 3y = -13

Plot the graph of both of these equations. The point of intersection, would be the solution of this system of equations. Refer to the graph attached. These lines intersect at (2, 7)

Therefore, the solution for the system of equations → y = 3x + 1  and

4x - 3y = -13 is (2, 7)

Answer:

5b + 2

Step-by-step explanation:

Frank is going to plant b vegetable seeds in one garden and 4b + 2 vegetable seeds in another.

We need to find how many seeds is frank going to plant.

It is equal to the sum of vegetable seeds in one garden and the vegetable seeds in another.

Sum = b + 4b + 2

Sum = 5b + 2

So, there are "5b + 2" seeds frank going to plant.

Answer:

D. 2:1 & 6:3

Step-by-step explanation:

Proportion means equal so we need to see which ratios are equal.

To do that we need to make one fo the numbers in the ratio equal the corresponding number in the other ratio, then see if the other matches.

A:

1:2 & 4:2

The second number is already the same but the first isn't, therefore it is not proportional.

B:

1:2 & 6:3

To get 1 to equal 6 we must multiply it by 6, and what you do to one side you must do to the other so we have to multiply 2 by 6 as well

6:12 & 6:3

The first numbers are the same but the second isn't, therefore it is not proportional.

C:

2:1 & 2:4

The first numbers are the same but the second isn't, therefore it is not proportional

D:

2:1 & 6:3

to get 2 to equal 6 we need to multiply it by 3, which means we have to multiu 1 by 3 too

6:3 & 6:3

These are equal so this is proportional.
