Aaron has 7/8 gallon of bottled water.How many 3/6 gallon servings can he pour
Anettt [7]
7/8 + 3/6 = 10/14 = 5/7 = 0.71 And if you want to make it a whole number, you multiply by 100 and you should get 71 as a whole number. Therefore: he can pour 71 gallon servings of bottled water. I hope this is helpful!!^_^!!

To obtain information on the corrosion-resistance properties of a certain type of steel conduit, 45 specimens are buried in soil
Fiesta28 [93]

Answer:

The sample has not met the required specification.

Step-by-step explanation:

As the average of the sample suggests that the true average penetration of the sample could be greater than the 50 mils established, we formulate our hypothesis as follow

H_0: The true average penetration is 50 mils

H_a: The true average penetration is > 50 mils

Since we are trying to see if the true average is greater than 50, this is a right-tailed test.

If the <em>level of confidence</em> is α = 0.05 then the z_\alpha score against we are comparing with, is 1.64 (this is because the area under the normal curve N(0;1) to the right of 1.64 is 0.05)

The z-score associated with this test is

z=\frac{\bar x-\mu}{s/\sqrt{n}}

where

\bar x = <em>mean of the sample</em>

\mu = <em>average established by the specification</em>

s = <em>standard deviation of the sample</em>

n = <em>size of the sample</em>

Computing this value of z we get z = 3.42

Since z >z_\alpha we can conclude that the sample has not met the required specification.

If a town has a density of 8 houses per block and there are 65 blocks in the town, how many houses are in the town?
andriy [413]

Answer:

520 houses

Step-by-step explanation:

Here, we are interested in calculating the number of houses in the town.

We are told that the density is 8 houses per block and there are 65 blocks

The number of houses in the town = density * number of blocks = 65 * 8 = 520 houses
