Answer:

-19/7

Step-by-step explanation:

If the variation is direct, any multiplier of the m-value will also multiply the f-value.

old value × 1/7 = new value

m: 14 × 1/7 = 2

f: -19 × 1/7 = -19/7

The new value of f is -19/7.

You want to leave a 15% tip on a meal that cost $65.00.

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or

0.15 x $65.00=$9.75.

So, the amount of tip you are going to leave is $9.75.

This makes the total cost of your meal (to write on your charge slip or other payment)

$65.00 + $9.75 = $74.75.

Answer:

Option D) Reject the claim that the proportion of Americans that have seen a UFO is equal to 5 in a thousand when that proportion is actually 5 in a thousand.

Step-by-step explanation:

We are given the following information:

A hypothesis test to support the given claim that the proportion of Americans that have seen a UFO is less than 5 in a thousand.

Type I error:

Type I error is the rejection of a true null hypothesis that is we reject the null hypothesis given it is true.
It is also known as a false positive.

First, we design the null and the alternate hypothesis

$H_{0}: \text{ The proportion of Americans that have seen a UFO is equal to 5 in a thousand}\\H_A: \text{ The proportion of Americans that have seen a UFO is less than 5 in a thousand}$

Thus, for the given hypothesis test, we describe type I error as:

Option D) Reject the claim that the proportion of Americans that have seen a UFO is equal to 5 in a thousand when that proportion is actually 5 in a thousand.
