Answers

the average value of something, is the (sum of the data elements) / (how many elements).

for example, in this case we have 5 elements, 5 delivery distances, so the average distance for them will be, their sum divided by 5, so let's do so them, firstly changing the mixed fractions to "improper" fractions,

If we were to imagine a single point (1,1) which is in quadrant 1, and we rotate it 90o then we get a negative x. Another 90o then both x and y is negative. another 90 (270) and we get a negative y.

how many shelves will display 2 cars if 8 of the shelves each display 1 car

Answers

1 car needs 8 shelves. You need to know how many for 2 cars, so 8 x 2 = 16

To determine the number of shelves that will display 2 cars each when 8 shelves display 1 car each, simply divide 8 by 2. The answer is 4 shelves.

To solve this problem, we'll use basic arithmetic. If each of the 8 shelves displays 1 car, then to display 2 cars on a shelf, we would need to combine pairs of shelves. This means we would take the 8 shelves, and divide by 2 cars per shelf to find the number of shelves needed for 2 cars each. So, 8 shelves divided by 2 cars per shelf equals 4 shelves.

Therefore, the answer is that 4 shelves will display 2 cars each if there were originally 8 shelves with 1 car each.

A high rise building has a sink on the fourth floor located 2-feet above the floor. Each floor is 10-feet above the other. Calculate the psi at the sink where when the street pressure is 80 psi. The building does not have a pressure reducing device due to fire codes.

Answers

The pressure at a certain height is the pressure at sea level plus the hydrostatic pressure.

P = 80 psi + ΔP
where
ΔP = ρgh
ρ is the density of water equal to 62.4 lbm/ft³
ΔP = (62.4 lbm/ft³)(1 lbf/lbm)(4*10 + 2 ft)(1 ft/12 in)² = 18.2 psi

Thus,
P = 80 + 18.2
P = 98.2 psi

5.3 miles?

111,513,600 miles?

Answers

The formula is f = 5280m

It means that every mile has to be multiplied by 5280 to connvert into equivalen number of feet.

Now you need to find the number of miles equivalent to 21,120 feet, so solve the equation f = 5280m for m:

f = 5280m => m = f / 5280

=> m = 21120 / 5280 = 4

y = the number of 10-ounce passion fruit juice used.

The cranberry juice runs out when
20x = 1260
x = 63  servings 

The passion fruit juice runs out when
10y = 650

Recall that you can use the built-in functions rem(m,n) or mod(m,n)to find the remainder of the division m/n.

Answers

the answer is B hope this helped
Final answer:

The 'rem(m, n)' and 'mod(m, n)' methods in mathematics provide the remainder of the division operation m / n. When dealing with numbers in exponential form, you divide the base numbers and subtract the exponents to simplify the terms. An understanding of these operations is essential for solving more complex equations.

Explanation:

In mathematics, there are two ways to find the remainder of a division operation: rem(m,n) or mod(m,n). These functions take two numbers m and n, and return the remainder when m is divided by n.

For example, in the case of 106 divided by 103, you would first divide the 'base' numbers (10/10) which equals 1, and then subtract the exponents (6-3) which equals 3. So, the result is 103 or 1000. Another example is 4.5 x 109 divided by 103. Here, first you divide 4.5 by 1 (since 10/10 = 1) and then subtract 9-3 equals 6. Therefore, the answer is (4.5) x 106.

For the past 7 years, George and Sue have deposited $10,000 in a retirement account with a simple interest rate of 4%. They plan to continue to make annual deposits for the next 15 years. Explain how their money will grow over time. Note: You do not need to extend their entire savings for 22 years in your explanation. Focus on the earning for the first several years and explain how their money will grow.

Answers

George and Sue's money will grow due to both to their contributions and the simple interest that they accrue. Simple interest means that the interest they receive will be applied to the principle, but not the interest that has been accrued. This means that for every $10,000 they put in, they will receive $400 dollars in interest every year, and this number will not change with time.

Right now, they've deposited 10,000 every 7 years for a total of 70,000 dollars. Their annual interest therefore is 400 * 7 = 2800. With every 10,000 dollars they deposit, the yearly interest will grow by $400. This is different from compounding interest, in which annual interest will grow by more than $400 dollars every year since the rate will be applied to principle and all accrued interest.

Answers

9 Times, hopes this helped

Answer: 9 times

Step-by-step explanation:

Let the total number students be x.

Then the number of students liked cookies and cream = 18% of x= 0.18 x

The number of strawberry = 2% of x = 0.02 x

Clearly, 0.18 x> 0.02 x

The number of times more students prefer cookies and cream than prefer strawberry =[tex]=\frac{0.18x}{0.02x}=9[/tex]

Hence, The students prefer 9 times cookies and cream than prefer strawberry.

... B: 16

plain hamburgers.

Final answer:

Jim and his dad will make 23 plain hamburgers.

Explanation:

To find the number of plain hamburgers Jim and his dad will make, we need to subtract the number of hamburgers with special toppings from the total number of hamburgers. There are 15 people in total, and each person wants 2 hamburgers, so Jim and his dad need to make 15 x 2 = 30 hamburgers in total.

Out of the 30 hamburgers, 3 people want hamburgers with cheese, 2 people want hamburgers with mustard, and 2 people want hamburgers with catsup. Therefore, the total number of hamburgers with special toppings is 3 + 2 + 2 = 7 hamburgers.

Subtracting the number of hamburgers with special toppings from the total number of hamburgers, we get 30 - 7 = 23 plain hamburgers. Therefore, Jim and his dad will make 23 plain hamburgers.

Answers

The 99% confidence interval for the population proportion is given by

[tex]sample \ proportion \pm 2.575\times standard \ error[/tex]

Given that 52% = 0.52 is the standard proportion and the standard error is 2.4% = 0.024.

Therefore, the 99% confidence interval for the fraction of u.s. adult twitter users who get some news on twitter is given by

[tex]0.52\pm2.575\times0.024=0.52\pm0.0618=(0.4582, \ 0.5818)[/tex]

Therefore, the 99% confidence interval for the fraction of u.s. adult twitter users who get some news on twitter is 45.82% and 58.18%.

The interpretation of the confidence interval is as follows: "We are 99% confident that the fraction of U.S. adult twiter users who get some news on twitter is between 45.82% and 58.18%.

For 99% confidence level, the interval will be (0.4582, 0.5818).

It can be interpreted as "45.82% to 58.18% of US adult will get information from twitter with a confidence of 99%".

Given information:

52% or 0.52 fraction of US adult twitter users get at least some news on twitter. It is the sample population in fractions.

The standard error is 2.4% or 0.024 fraction.

Normal distribution may be used to model the sample proportion.

[tex]I=\texttt{sample population}\pm 2.575\times \texttt{standard error}\\I=0.52\pm 2.575\times0.024\\I=0.52\pm 0.0618\\I=(0.4582, 0.5818)[/tex]

Therefore, for 99% confidence level, the interval will be (0.4582, 0.5818).
