Write fractions to the least to the greatest 1/5,2/3,5/8
xenn [34]

Answer:1/5, 5/8, 2/3

Step-by-step explanation:

Using 1/2 as a benchmark, 1/5 is the only one less than 1/2. That is the least. You can turn 2/3 and 5/8 into fractions with common denominators. 2/3=16/24 and 5/8= 15/24. 5/8 is less than 2/3, therefore resulting in the answer.

If 2/3 ton of gravel covers 3/4 of a driveway, how many tons of gravel are required to cover the entire driveway?
Paladinen [302]
Oh come on!! Look at this:

If 2/3 ton of gravel covers 3/4 of a driveway, you need to divide 2/3 divided by 3 to find how much is needed for 1/4 of the driveway. So first step:

1. 2/3 divided by 3 = 2/3 * 1/3. So 2/9.
2. Add 2/3 plus 2/9= 8/9 ton of gravel to cover the whole driveway.

Birthdays of hockey players: In Malcolm Gladwell’s book "Outliers" he shares the work of Canadian psychologist Roger Barnsley, w
alexgriva [62]

Answer:

The P-value is 0.009.

Step-by-step explanation:

We are given that after debating whether this set of hockey players can be viewed as a random sample of hockey players, they decide to run a hypothesis test anyway to practice finding the P‐value.

<em><u>We are given that the following hypothesis below;</u></em>

Null Hypothesis, H_0 : p = 0.25

Alternate Hypothesis, H_A : p > 0.25

Now, the test statistics that was used here for the above hypothesis would be;  

                       T.S.  =  \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }  ~ N(0,1)

Also, the test statistics given to us is 2.37.

<u></u>

<u>SO, the P-value of the test statistics is given by the following formula;</u>

             P-value = P(Z > 2.37) = 1 - P(Z \leq 2.37)

                           = 1 - 0.99111 = 0.00889 ≈ 0.009

<em>The above probability is calculated by looking at the value of x = 2.37 in the z table which has an area of 0.99111.</em>

Therefore, the required P-value is 0.009.
