How many pints are in 10 gallons?

Ksju [112]

There are 4 quarts in a gallon, and 2 pints in each quart. so take 10 gallons and multiply it by 4 then by 2 which gives you 80 pints in a gallon. or realize that there are 8 pints in a gallon so multiply 10 by 8 which again gives you 80.

80 pints in a gallon

there are 16 ounces in a pound, but you are trying to get back to the larger unit, rather than the smaller one, so you do the opposite of what we did in the first problem. We do the opposite of multiplying which is dividing. we divide 112 ounces by 16 to get back to pounds. 112 divided by 16 is 7

there are 7 pounds in 112 ounces

Solve for b.<br> 16 = a² + b^2

laiz [17]

Answer:

$\sqrt{(4-a)(4+a)} =b$

Step-by-step explanation:

16 = a^2 + b^2

16 - a^2 =b^2

4^2 - a^2 = b^2

$\sqrt{4^2 - a^2} =b$

$\sqrt{(4-a)(4+a)} =b$

OLga [1]

Answer:

(-239.4, 657.8) km/h

Step-by-step explanation:

Measured CCW from the +x axis, the angle at which the airplane is traveling is 110°. Then the (x, y) components of the velocity vector are ...

(700 km/h)(cos(110°), sin(110°)) ≈ (-239.4, 657.8) km/h

A 95% confidence interval for a population mean is (28, 35). Using the same data at 5% level of significance, what should you de

iris [78.8K]

Answer:

A) Fail to reject the null hypothesis because 34 falls in the 95% confidence interval.

Step-by-step explanation:

We are given the following information in the question:

A 95% confidence interval for a population mean is (28, 35)

Alpha, α = 0.05

The null and the alternate hypothesis are:

$H_{0}: \mu = 34\\H_A: \mu \neq 34$

A confidence interval also known as the acceptance region, is a set of values for the test statistic for which the null hypothesis is accepted.
If the observed test statistic lies in the confidence interval then we accept the null hypothesis and reject the alternative hypothesis.
If the observed test statistic is in the critical region then we reject the null hypothesis and accept the alternative hypothesis.

Hence, we fail to reject the null hypothesis and accept it because 34 falls in the 95% confidence interval.
