Jake walks a mile to work. If Jake has already walked two-fifths of a mile, how many more feet must he walk to get to work?

Alexxx [7]

1 mile is equal to 5280 feet.

5/5 - 2/5 = 3/5 of a mile left to walk

3/5m * 5280 ft/1m = (3m*5280ft)/(5*1m) = 15840ft/5 = 3158 feet left to walk to get to work.

Or
5280 feet / 5 = 1056 ft * 2 = 2112 ft walked to get to work
5280 - 2112 = 3168 feet left to walk to get to work.

Faye pays her family phone bill, and Jonathan’s family phone bill with her card and jonathan pays her back. If Faye bill is $120

nika2105 [10]

Answer:

Jonathan has to pay Faye back US$ 240

Jonathan has 4 people on his bill and Faye has 6.

Step-by-step explanation:

1. Let's find out the amount of the phone bills, this way:

Total of the two bills = US$ 600

Faye's bill = US$ 120 more than Jonathan's

Jonathan's bill = x

Solving for x, we can use this equation:

x + x + 120 = 600

2x + 120 = 600

2x = 600 - 120

2x = 480

x = 480/2 = 240

Jonathan has to pay Faye back US$ 240

2. Let's find out the number of people on each bill, this way:

Faye has two people more on her bill than Jonathan

Number of people on Jonathan's bill = x

Number of people on Faye's bill = x + 2

We will use the following equation:

240 * (x + 2) = 360x

240x + 480 = 360x

240x - 360x = -480

-120x = - 480

x = -480/-120

x = 4 ⇒ x + 2 = 6

Jonathan has 4 people on his bill and Faye has 6.

(a) determine the null and alternative hypotheses, (b) explain what it would mean to make a Type I error, and (c) explain what i

iren2701 [21]

Null: the mean amount of peanut butter in a jar is equal to 32 oz.
alternative: the mean amount of peanut butter in a Jar is less than 32oz.

type 1 error is is rejecting the null when it is actually true. this means that we would say that the mean amount of peanut butter is not equal to 32 when it actually is.

type 2 error is failing to reject the null when it is actually false. this means that we would say the mean amount of peanut butter is equal to 32 when in reality it is less.
