Answer:

3 \frac{3}{4}

Step-by-step explanation:

To find the unit rate, the only thing you need to do to find the unit rate is to divide the two values we have. In this case, the two values represent the square yards and the speed in which the action is done.

\frac{5}{4} : \frac{1}{2} = \frac{5}{4} * \frac{3}{1} = \frac{15}{4} = 3 \frac{3}{4}


Hope it helped,

Answer:

15/4 yds^2 per hour

or

3 3/4 yds^2 per hour

Step-by-step explanation:

To find the unit rate, we take the square yards and divide by the hours

5/4 ÷ 1/3

Use copy dot flip

5/4 * 3/1

15/4

15/4 yds^2 per hour

or changing to a mixed number

3 3/4 yds^2 per hour

A student in wildlife management studied trout habitat in the upper Shavers Fork watershed in West Virginia. The springtime wate
nataly862011 [7]

Answer:

C. H 0 : μ = 7 vs. Ha : μ ≠ 7

Since the calculated value of t = -9.462 falls in the critical region  t ≤-2.048

We conclude that the  springtime water the tributary water basin around the Shavers Fork watershed is not neutral. We accept our alternate hypothesis and reject the null hypothesis.

Step-by-step explanation:

The null hypothesis the usually the test to be performed. Here we want to check whether the water is neutral or not. Neutral water must have a pH of 7 . This can be stated as the null hypothesis. And the claim is treated as the alternate hypothesis that water in not neutral or not having pH= 7

In symbols it will be written as

H0: : μ = 7 vs. Ha : μ ≠ 7

So choice C is the best option for this hypothesis testing.

Let the significance level be 0.05

The degrees of freedom = n-1= 29-1 = 28

The critical value is  t ≥ 2.048 and t ≤ - 2.048 for 0.05 two tailed test with 28 df.

The test statistic to use is t- test

t= x- u/ s/√n

The total sum is 170.9 and mean = x= 5.893

The u = 7

And the sample standard deviation is =s= 0.63

Putting the values

t= 5.893-7/0.63/√29

t= - 1.107/0.11699

t= -9.4623

Since the calculated value of t = -9.462 falls in the critical region  t ≤-2.048

We conclude that the  springtime water the tributary water basin around the Shavers Fork watershed is not neutral. We accept our alternate hypothesis and reject the null hypothesis.

What is the potential energy of a 500kg elevator that is 4.0m high from the floor?
rodikova [14]

Answer:

<h2>19,600 J</h2>

Step-by-step explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

We have

PE = 500 × 9.8 × 4

We have the final answer as

<h3>19,600 J</h3>

Hope this helps you
