Answer:

1. Lin raised $40

2. Jada raised $20

3. Andre raised $60

Step-by-step explanation:

1. It says Lin raised 100% of her goal and the goal was $40 which means that she earned $40

2. For this one it says Jada raised only 50% of her goal. To solve this one you just take half of 40 since it says she raised only 50% of her goal which gets you 20

3. For this one you just have to do some adding. The first part of the problem you take away the 50% of the 150% for a minute and that just leaves 100% which is a total of 40$ you then just look at the 50% by itself which is 20$. Then you take 40 and add the 20 to it which gets you a total of 60$

have a great day! :)

What’s the domain and range? An airplane travels at 565 mph.

viktelen [127]

Answer:

Domain:

The domain of this can be any value between 0 to 565 miles per hour

Range:

The reasonable range can be the distance traveled which can be from 0 to 13,560 miles (no plane travel is longer than 24 hours, we assume).

Step-by-step explanation:

Domain is the input, set of x values for the function.

Range is the output, set of y values for the function.

This isn't a function essentially, but it is given that an Airplane travels at 565 miles per hour.

We can say that the domain will be the speed of the airplane and the range would be the distance it travels.

Domain:

The domain of this can be any value between 0 to 565 miles per hour

Range:

The reasonable range can be the distance traveled which can be from 0 to (565*24=13,560 miles) 13,560 miles (no plane travel is longer than 24 hours, we assume).

A one-tailed test is a a. hypothesis test in which rejection region is in one tail of the sampling distribution b. hypothesis te

garri49 [273]

Answer:

Option A) One tailed test is a hypothesis test in which rejection region is in one tail of the sampling distribution

Step-by-step explanation:

One Tailed Test:

A one tailed test is a test that have hypothesis of the form

$H_0: \bar{x} = \mu\\H_A: \bar{x} < \mu\text{ or } \bar{x} > \mu$

A one-tailed test is a hypothesis test that help us to test whether the sample mean would be higher or lower than the population mean.
Rejection region is the area for which the null hypothesis is rejected.
If we perform right tailed hypothesis that is the upper tail hypothesis then the rejection region lies in the right tail after the critical value.
