Answer:

Mixed: 722/100

Improper: 7 22/100

Step-by-step explanation:

Since you can't simplify it looks like we have to stay with:

7 -> 700/100

.22 -> 22/100

722/100

.22 -> 22/100

7 + 22/100

Find the mean of the data
Triss [41]
<h3>Answer:  6.282</h3>

Explanation:

Refer to the table below. I've added a third row where I multiplied each x value with its corresponding frequency value f. We can refer to this row as the xf row.

Once we know the xf values, we add them up to get 245.

We'll then divide that result over the sum of the frequency values (add everything in the second row). The sum of the frequency values is 39.

So the mean is approximately: 245/39 = 6.282051 which rounds to 6.282

Notice that this mean value is fairly close to the x value which has the highest frequency.

The number of assists per match for the setter on your school's volleyball team has a mean of 58 and a standard deviation of 7.
serious [3.7K]
To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143

The answer is 1,670 because you have to multiply 35*8 which equals 280 and subtract it from 1950, and you get 1,670.
