jenny has $55 in her checking account, he bought 7 equally priced dvds and paid with a check. her new account balance is -$22. how much was each dvd?

Answers

Answer:

Jenny spent $11 on each dvd she bought.

Step-by-step explanation:

First and foremost, add 55 and 22 since her account balance is now at -$22 since that shows she spent even more.

55+22= 77

Next step divide 7 into 77 since that's how many dvds jenny bought.

77÷7= 11

The answer is $11. Jenny spent $11 on each dvd she bought.

1. Many of the continuous random variables that occur in real life are approximately normally distributed. How do you think this helps in studying real life variables?

2. Do you realize and understand the advantage of being able to convert values of an arbitrary normally distributed random variable to the corresponding values of the standard normal variable? If yes, list all the possible advantages of being able to do this. If not what do you plan to do to understand why the standard normal random variable is widely used for computations involving normal distributions?

What is the total amount of fabric needed to make the tent with the following dimensions?

Answers

I’m just guessing that it’s asking for surface area, since fabric doesn’t fully fill an object.

I kind of forgot about surface area so this isn’t going to be 100% accurate, but I believe that you multiply the base by the other numbers.
For example, you get the base of the side, 6 ft. , and you multiply it by the height, which gives 24. Then, you multiply it by 2, since there’s two sides.

Then you do 6x5 (30), and so on and so forth.

(I’m so sorry if I’m wrong, I haven’t really done area or surface area in a while lol)

The following is an estimated demand function: Q = 875 + 6X +15Y − 5P Where Q is quantity sold, X is advertising expenditure (in thousands of dollars), Y is income (in thousands of dollars), and P is the good's price. The R2 was 0.92; the F-statistic was 57; the Standard Error of the Estimate (SEE) is 25. In the above regression: A. income has the highest importance in predicting sales. B. all of the options. C. the regression model is capable of explaining 92% of sales. D. if price increases 10 dollars, the sales will decrease 50.

Answers

Answer:

See step by step explanation

Step-by-step explanation:

Q = 875  + 6 * Adv. expenditure + 15* Income - 5 * Product price

A.- As we can see each unitary change (in thousands of $) in Income, will mean an increase of  15 $ (thousands ) in the demand function, the highest impact in Q

C.- The regression model is capable of explaining  92 % of the variation in Q due to the predictors.

D.- If the price is increased by 10 $ demand will decrease in 50

Duncan ran 26.2 miles in 4 hours 10 minutes. At this rate, rounded to the nearest tenth, how long did it take Duncan to run each mile?

Answers

Answer:

Time taken for cover 1 miles = 0.16 hour (Approx.)

Step-by-step explanation:

Given:

Total distance cover by Duncan = 26.2 miles

Time taken by Duncan = 4 hours 10 minutes

Find:

Time taken for cover 1 miles

Computation:

Time taken by Duncan = 4 hours 10 minutes

Time taken by Duncan = 4 + 0.167 hour

Time taken by Duncan = 4.167 hour

Speed = Distance / Time

Speed = 26.2 / 4.167

Speed = 6.28 miles/hour (Approx.)

So,

Time taken for cover 1 miles = 1/6.28

Time taken for cover 1 miles = 0.16 hour (Approx.)
