Ok so we know that in ONE second, the dam releases 40000 gallons of water. In ONE minute, there are 60 seconds. Therefore...

1 second----------------40000 gallons
60 seconds--------------? ( this is what we're trying to find.

To get from 1 to 60, we multiplied by 60. Now we do it on the other side. 40000 times 60 is 2,400,000, so the rate in gallons per minute is 2,400,000 gallons per minute

Answer:

Water releases in 1 minute = 2400000 gallons.

Step-by-step explanation:

Given : One of the valves on the Hoover Dam releases 40000 gallons of water per second.

To find : what is the rate in gallons per minute.

Solution : We have given

Water releases in 1 second = 40000 gallons.

1 minute = 60 second.

Water releases in 60 second = 40000 * 60 gallons.

Water releases in 1 minute = 2400000 gallons.

Therefore, Water releases in 1 minute = 2400000 gallons.

kvasek [131]

Answer:

Step-by-step explanation:

From the given information;

The null and alternative hypothesis is:

$\mathbf{H_o: \mu =0}$

$\mathbf{H_a: \mu \ne 0}$

sample mean x = -2

population mean = 0

SD = 6

sample size n = 25

Using t-test statistics:

$t = \dfrac{x- \mu}{\dfrac{\sigma}{\sqrt{n}}}$

$t = \dfrac{-2- 0}{\dfrac{6}{\sqrt{25}}}$

t = -1.667

P-value = P(t ≤ -1.667) + P(t ≥ 1.667)

P-value = 0.1086

Since P-value is greater than $H_o$ , we fail to reject $H_o$ .

Anna has 10 to the 2nd power quarters. Jazmin has 10 to the second power dimes Who has more money, Anna or Jasmine? How much mor

Burka [1]

Anna has more money... We don't have to do messy calculations for this... Both have 10 to the 2nd power "some amount". 10 to the second power is 100. So they both have 100 coins.

A quarter is 25 cents, while a dime is only 10 cents. Since they both have the same amounts of coins, the one with 100 quarters has more money, so Anna has more money than Jasmine.

Now, we need to figure put by how much! 100 quarters is one hundred 25 cent coins. 100*25 = 2500. That is 25 dollars. Whereas, Jasmine has one hundred times 10 cents, which is 1000 cents. This is 10 dollars.

So, Anna has 15 more dollars than Jasmine.
