Solve these multi step equations. Show your work. Justify each of your steps. 3x+4+6x=12-41+6x

Answers

Answer:

x=11

Step-by-step explanation:

Combine like terms:

3x +4 +6x =12- 41+ 6x

9x +4 =12 -41 + 6x

Subtract the numbers:

9x+ 4= 12- 41+ 6x

9x + 4= -29 +6x

Rearrange terms:

9x+4=-29+6x

9x+4=6x-29

x=11

The lifetime of a certain brand of battery is normally distributed with a mean value of 9 hr and a standard deviation of 0.8 hr when it is used in a particular DVD player. Suppose that two new batteries are independently selected and put into the player. The player stops functioning as soon as one of the batteries fails. (Round your answers to four decimal places.)

Required:
a. What is the probability that the player functions for at least 8 hr?
b. What is the probability that the cassette player works for at most 11 hr?
c. Find a number z* such that only 10% of all cassette players will function without battery replacement for more than z* hr.

Answers

Answer:

a. 0.8944 = 89.44% probability that the player functions for at least 8 hr

b. 0.9938 = 99.38% probability that the cassette player works for at most 11 hr

c. z* = 10.024 hr

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean value of 9 hr and a standard deviation of 0.8 hr

This means that [tex]\mu = 9, \sigma = 0.8[/tex]

a. What is the probability that the player functions for at least 8 hr?

This is 1 subtracted by the pvalue of Z when X = 8. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{8 - 9}{0.8}[/tex]

[tex]Z = -1.25[/tex]

[tex]Z = -1.25[/tex] has a pvalue of 0.1056

1 - 0.1056 = 0.8944

0.8944 = 89.44% probability that the player functions for at least 8 hr.

b. What is the probability that the cassette player works for at most 11 hr?

This is the pvalue of Z when X = 11. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{11 - 9}{0.8}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a pvalue of 0.9938

0.9938 = 99.38% probability that the cassette player works for at most 11 hr.

c. Find a number z* such that only 10% of all cassette players will function without battery replacement for more than z* hr.

This is the 90th percentile, which is X when Z has a pvalue of 0.9, that is, X when Z = 1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 9}{0.8}[/tex]

[tex]X - 9 = 1.28*0.8[/tex]

[tex]X = 10.024[/tex]

So

z* = 10.024 hr

Answer:

B. owners

Step-by-step explanation:

Sole proprietorship can be defined as a type of business that is typically owned by an individual or one person and as such is solely responsible for its debts.

In a sole proprietorship, owners receive all of the profits because they own the business and do not share with any partner.

Basically, a sole proprietorship business is a type of business that is owned by a single person and as such their profits are taxed once as personal income tax.

This question is based on the equation of circle. Therefore, the equation of circle is (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

What is circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

Given:

A circle with center (4, -7) and radius 9.

We need to determined the equation describes a circle with center (4, -7) and radius 9.

According to the question,

As we know that, the equation of a circle in standard form is

⇒ (x - h)² + (y - k)² = r²

Where (h, k) are the coordinates of the center and r is the radius.

Here, it is given that,  (h, k) = (4, - 7) and r = 9.

Therefore, by putting the given values.

We get,

⇒ (x - 4)² + (y - (- 7))² = 9², that is

⇒ (x - 4)² + (y + 7)² = 81 ← equation of circle

Therefore, the equation of circle is  (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

1. Savannah has 5 dogs and she feeds each of them 6 oz of dog food every day. How many
pounds of dog food do they eat each day?

Answers

Answer:

0.375 lb

Step-by-step explanation:

For this one all you need to do is convert 6 oz to pounds and to do this

For example to convert an ounce measurement to a pound measurement, use a simple formula. Since one ounce is equal to 1/16 of a pound, the formula for the conversion is:

pounds = ounces ÷ 16

1. Take measurement

2. Divided ounces by 5

3. Round the result to desired decimal places.

And don't just put this answer because I am not very sure.

1.875 pounds of dog food can be eaten by 5 dogs per day.

Pound and ounce based problem:

What information do we have?

Number of dogs = 5

Each dog eats per day = 6 oz

Total dog food eaten per day = Number of dogs × Each dog eats per day

Total dog food eaten per day = 5 × 6

Total dog food eaten per day = 30 oz

1 pound = 16 oz

So,

Total dog food eaten per day = 30oz / 16oz

Total dog food eaten per day =  1.875 pound

Step-by-step explanation:

combine like terms: the 10x and the 2x can be combined making it 12x and then you keep the -3y making it 12x-3y

Answer:

12x - 3y

Step-by-step explanation:

All you have to do for this question is combine like terms. It isn't wanting you to solve for anything, so it's pretty fast to do. Since the 2 and 10 both have x values next to them, you can combine them. They are both positive, so you can simply add them together. This gives you 12x. Because the -3 and 12 have different values next to them, you cannot combine them. So you are left with 12x - 3y. This is your answer.

I hope this makes sense and is easy to understand. Please let me know if you need any more help. Have a great day and good luck!!
