Answer: 50

Step-by-step explanation:

equation is 5x-40+150=360

combine like terms = 5x+110=360
Subtract 110 from both sides = 5x=250

Answer:

1) The convers of the conditional statement is;

If the ratio of lefties to righties is 1:8,  then a class has 3 left-handed people and 24 right-handed people

2) The convers of the conditional statement is true

Step-by-step explanation:

1) The given statement is presented as follows;

"If a class has 3 left-handed people and 24 right-handed people, then the ratio of lefties to righties is 1:8"

The hypothesis = A class has 3 left-handed people and 24 right-handed people = p

The conclusion = The ratio of lefties to righties is 1:8 = q

We have;

If p, then q which is p → q

The converse statement = If q, then p which is q → p

Then the converse of the conditional statement can be written as follows;

If the ratio of lefties to righties is 1:8,  then a class has 3 left-handed people and 24 right-handed people

2) Given that the ratio of 3:24 = 1:8, we have that both the hypothesis and the conclusion are true, therefore, the converse of the conditional statement is true.

The hypotheses of the company are:

The hypotheses consist of the null and the alternate hypotheses

The null hypothesis is always represented by the equal to "=" sign.

So, the null hypothesis is:

H0: The mean life of Brand A is 1000 hours

From the question, we understand that the evidence is to show that the mean life is greater than Brand B.

So, the alternate hypothesis is:

H1: The mean life of Brand B is more than 1000 hours

120ft³ = 3ft × 4ft × 10ft

120ft³ = 1ft × 1ft × 120ft

120ft³ = 2ft × 2ft × 30ft

120ft³ = 5ft × 3ft × 8ft

Answer: The value of b is $0.15.

Step-by-step explanation:

Total bottles co0llected = 14+9 =23

Payment for each bottle = b

Total payment she will get = 23b

One -time service fee = $0.25

She has left = $3.20

According to the question,

23b - 0.25 = 3.20

⇒23b = 3.20+0.25

⇒23b = 3.45

⇒b = 0.15   [divide both sides by 23]

Cost of each bottle = $ 0.15

hence, the value of b is $0.15.

[tex] \huge \boxed{y = - \frac{1}{2} x - 8 }[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (0,-8) and slope - 1/2

We have

[tex]y + 8 = - \frac{1}{2} (x - 0) \\ y + 8 = - \frac{1}{2} x \\ y = - \frac{1}{2}x - 8[/tex]

We have the final answer as

[tex]y = - \frac{1}{2} x - 8 \\ [/tex]

The overlap of team 1 and team 2 whose data area expressed in the form of dot plot representation is high.

The dot plot is the way of representation of the data. This data is plotted in the form of points or dots over an x-y axes. The dot plot is also known as the strip plot.

Figure of the dot plot of the team 1 and team 2 is attached below. The overlap of the team 1 and the team 2 has to be found out.

The overlaps mean in the dot plot is height, which both the graphs of dot plot have in same.

In the attached image, it seen that the overlap of the team one and team 2 is higher.

Step-by-step explanation:

Recall that the surface area A for a cylinder is given by:

[tex]\displaystyle A=2\pi r^2+2\pi rh[/tex]

And we want to solve for the height h.

First, subtract [tex]2\pi r^2[/tex] from both sides. This yields:

[tex]2\pi rh= A-2\pi r^2[/tex]

Now, we can dvide both sides by [tex]2\pi r[/tex]. This yields:

Step-by-step explanation:

The difference in total premium costs over 20 years at the two age levels is $12875.

Face value is a term used to describe the nominal value of a security, as stated by its issuer.

Let us consider the entire scenario for a 40-year old male.

Annual life insurance premium per 1000 of face value = $22.60

So, the annual life insurance premium for a $125,000 whole life insurance policy = 125000/1000 * 22.60 = $2825.

For 20 years the premium will be = 2825*20 = $56500

Let us consider the entire scenario for a 45-year old male.

Annual life insurance premium per 1000 of face value = $27.75

So, the annual life insurance premium for a $125,000 whole life insurance policy = 125000/1000 * 27.75 = $3468.75

For 20 years the premium will be = 3468.75*20 = $69375

The difference in total premium costs over 20 years = 69375-56500 The difference in total premium costs over 20 years = $12875

Therefore, The difference in total premium costs over 20 years at the two age levels is $12875.
