Answer:

Step-by-step explanation:

Pythagorean theorem:

a^2 + b^2 = c^2

(6 km)^2 + b^2 = (7 km)^2

36 + b^2 = 49

b^2 = 13

b = sqrt(13)

b = 3.6

Answer: 3.6 km

A parking space is 20 feet long. A pickup truck is 6 yards long. How many inches longer is the parking space than the truck

masya89 [10]

1 yard = 3 feet.

Multiply the length of the truck by 3 to get total feet:

6 x 3 = 18 feet.

Subtract the length of the truck from the length of the parking space:

20 - 18 = 2 feet

1 foot = 12 inches.

Multiply 2 feet by 12:

2 x 12 = 24 inches longer.

Answer:

The null hypothesis is $H_0: \mu = 2.5$ .

The alternative hypothesis is $H_1: \mu > 2.5$

Step-by-step explanation:

Suppose that a recent article stated that the mean time spent in jail by a first-time convicted burglar is 2.5 years.

At the null hypothesis, we test if the mean is of 2.5 years, that is:

$H_0: \mu = 2.5$

A study was then done to see if the mean time has increased in the new century.

At the alternative hypothesis, we test if the mean has increased, that is, if it is above 2.5 years. So

$H_1: \mu > 2.5$
