Answer:

The answer would be 2:30

Step-by-step explanation: lets say they both take 3 hours, that would mean that if they work together, that means they can cut their time by half,

but if jai is slower paced it and takes about 1 hour more, just add 1 hour to the hour and 30 to be able to get 2:30

A headline in a major newspaper read, "Breast-fed youth found to do better in school."a. Do you thinkthis statement was based on
Maurinko [17]

Answer:

Randomized experiment

Step-by-step explanation:

Such a statement is said to be Randomized experiment as the kids in the school have been selected at random and their performances are observed and recorded. Later it is inquired if they are breast fed or not. This information is later assessed and a conclusion is reached. This type of research or experiment is Randomized experiment.

Considering that the experiment is Randomized, the statement should be "Link found between breast-feeding and school performances". This statement does not restrict the performances of the student specifically on breast-feeding but shows a probable affect of it.

Suppose you know that the volume of the following prism is represent by V(x) = -2x^3 + 14x^2 + 120x.
erastova [34]

Step-by-step explanation:

-2x³ + 14x² + 120x

= -2x(x² - 7x - 60)

= -2x(x - 12)(x + 5).

The other 2 dimensions are -2x and (x + 5).

When using a graphing calculator to maximise the volume of the prism, we get x = 7.378. However this value is not reasonable as it makes -2x and (x - 12) negative, which are the sides of the prism.

Subtract 43 from 20 raised to the 7th power; then multiply by 3.
viktelen [127]

Hi there! :)

<u>Answer:</u>

Subtract 43 from 20 raised to the 7th power; then multiply by 3. The answer is: <u>3,839,999,871</u>

Step-by-step explanation:

"Subtract" means to take away a number from another.

" 20 raised to the 7th power" is the same thing as 20 exponent 7: 20^{7}


SO, you want to take away 43 from 20^{7} and then multiply the answer by 3:

(20^{7} - 43) × 3

20^{7} = 1,280,000,000

(1,280,000,000 - 43) × 3

1,280,000,000 - 43 = 1,279,999,957

1,279,999,957 × 3

1,279,999,957 × 3 = <u>3,839,999,871</u>


There you go! I really hope this helped, if there's anything just let me know! :)
