Answer:

$7.29 per hour  at her new job.

Step-by-step explanation:

Answer:

$3.60

Step-by-step explanation:

Her hourly wage at her old job is 729/45 or $16.20 per hour. If her salary is increased by 10% then her wage weekly is $801.90. If her hours are reduced by 10% then she has to work 40.5 hours per week. This means you have to do  801.90/40.5 to get $19.80 per hour. So according to my math here she will make $3.60 more per hour at her new job. (Double check to make sure I'm correct)

Answer:

0.9646 ; 0.5685

Step-by-step explanation:

Given that :

P(obtaining 3 on a die roll) = 1/6 = 0.1667

Obtaining 3 at most 2 times in five trials

Using binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

n = 5 ;, p = 0.1667

P(x ≤ 2) = P(x = 0) + P(x =1) + P(x = 2)

Using the binomial probability :

P(x ≤ 2) = 0.4019 + 0.4019 + 0.1608

P(x ≤ 2) = 0.9646

B.) using geometric distribution :

(1 - p)^x-1 * p

P ≥ 5) = 1 - P(x ≤ 4) = 1 - p(x = 0) + p(x = 1) + p(x =2) + p(x = 3)

1 - (0.1667 + 0.1157+0.0965+0.0804)

= 0.5685

Answer:

158 m²

Step-by-step explanation:

I made this into 3 rectangles.

Figure 1:

9•8=72

The 9 is from the 13 m side, but I've taken 4 m off from the overlapping square.

Figure 2:

6•7=42

The 7 is from the 10 m side, but I've taken 4m off from the overlapping square again.

Remaining Area:

If you extend the lines into figures 1 and 2 from the top left corner and bottom right corner vertically, you will get a rectangle that is (11 m) x (4 m). This is not yet accounted for.

11•4=44

Add together: 72 + 42 + 44 = 158

*Note: You could also find the area of the squares a much easier way by subtracting the overlapping part after finding the area of both figures , but this is how I did it*

store A is 278.4 and store B is 260 and the cost for one shirt from store b is 8.125

Step-by-step explanation

6.96 x 40 gives you 278.4

325 - 20% gives you 260

325 divided by 40 gives you 8.125

then to check your answer you multiply 40 and 8.125 and it gives you 325

Answer:

i tink is b

Step-by-step explanation:

The equation that represents the situation will be 4r + 350 = 550. Then the correct option is A.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

A family is driving 550 miles to their grandmother's house. They have already driven 350 miles.

Let 'r' be the speed of the car in miles per hour. The family must drive to reach their grandmother's house in 4 hours. Then the equation is given as,

4r + 350 = 550

The equation that represents the situation will be 4r + 350 = 550. Then the correct option is A.

Answer:

0.6889 = 68.89% probability that a customer likes this flavor the first time and the second time

Step-by-step explanation:

For each time the customer is asked, there are only two possible outcomes. Either they like the flavor, or they do not. Each event is independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The probability that a customer likes the new flavor is .83.

This means that [tex]p = 0.83[/tex]

What is the probability that a customer likes this flavor the first time and the second time

This is P(X = 2) when n = 2. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{2,2}.(0.83)^{2}.(0.17)^{0} = 0.6889[/tex]

0.6889 = 68.89% probability that a customer likes this flavor the first time and the second time

You will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.

Given that,

Room dimensions:

Length: 16 feet

Width: 10 feet

Height: 8 feet

Features on the walls:

Two windows:

Width: 2 feet

Height: 5 feet

One door:

Width: 4 feet

Height: 7 feet

Paint coverage:

1 gallon of paint covers 350 square feet

Calculate the area of the walls first:

Subtract the area of the windows and door area from the total wall area.

The total wall area is the sum of the areas of all four walls.

The area of each wall is calculated by multiplying the height of the room by its length.

So, the area of each wall = 8 feet (height) x16 feet (length)

The area of each wall = 128 square feet.

Calculate the area of the windows and the door.

The area of each window is calculated by multiplying its width by its height.

So, the area of each window = 2 feet (width) x  5 feet (height)

The area of each window = 10 square feet.

The area of the door is calculated by multiplying its width by its height. So,

The area of the door = 4 feet (width) x 7 feet (height)

The area of the door  = 28 square feet.

Now, subtract the total area of the windows and the door from the total wall area.

Total wall area = 4 walls x 128 square feet

Total wall area  = 512 square feet

The total area of the windows = 2 windows x 10 square feet

The total area of the windows = 20 square feet

The total area of the door = 1 door x 28 square feet

The total area of the door = 28 square feet

Area to be painted = Total wall area - Total area of the windows - Total area of the door

Area to be painted = 512 square feet - 20 square feet - 28 square feet

Area to be painted = 464 square feet.

Now, we can determine the number of gallons of paint needed.

Since 1 gallon of paint covers 350 square feet,

Divide the area to be painted by 350.

The number of gallons of paint needed = Area to be painted / Coverage per gallon

The number of gallons of paint needed = 464 square feet / 350 square feet/gallon

The number of gallons of paint needed ≈ 1.33 gallons.

Hence, you will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.

Answer: 5.2 units

Step-by-step explanation:

This is a right-angled triangle which means that the missing length can be solved using the Pythagorean theorem:

Where c is the hypotenuse

a and b are the other sides.

c =  6

a = 3

b = ?

6² = 3² + b²

Here we will show you step-by-step with detailed explanation how to calculate 246 divided by 7 using long division.

Before you continue, note that in the problem 246 divided by 7, the numbers are defined as follows:

246 = dividend

7 = divisor

Step 1:

Start by setting it up with the divisor 7 on the left side and the dividend 246 on the right side like this:

7 ⟌ 2 4 6

Step 2:

The divisor (7) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

0

7 ⟌ 2 4 6

Step 3:

Multiply the divisor by the result in the previous step (7 x 0 = 0) and write that answer below the dividend.

0

7 ⟌ 2 4 6

0

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

0

7 ⟌ 2 4 6

- 0

2

Step 5:

Move down the 2nd digit of the dividend (4) like this:

0

7 ⟌ 2 4 6

- 0

2 4

Step 6:

The divisor (7) goes into the bottom number (24), 3 time(s). Therefore, put 3 on top:

0 3

7 ⟌ 2 4 6

- 0

2 4

Step 7:

Multiply the divisor by the result in the previous step (7 x 3 = 21) and write that answer at the bottom:

0 3

7 ⟌ 2 4 6

- 0

2 4

2 1

Step 8:

Subtract the result in the previous step from the number written above it. (24 - 21 = 3) and write the answer at the bottom.

0 3

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3

Step 9:

Move down the last digit of the dividend (6) like this:

0 3

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

Step 10:

The divisor (7) goes into the bottom number (36), 5 time(s). Therefore put 5 on top:

0 3 5

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

Step 11:

Multiply the divisor by the result in the previous step (7 x 5 = 35) and write the answer at the bottom:

0 3 5

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

3 5

Step 12:

Subtract the result in the previous step from the number written above it. (36 - 35 = 1) and write the answer at the bottom.

0 3 5

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

- 3 5

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 246 divided by 7 calculated using Long Division is:
