Use calculators it helps me hope it helps you
In order to find the mean of a set of data.
STEP 1: Add all of the data values.
STEP 2: Divide by the amount of values.
STEP 3: There is your answer
I hope this helps you find the solution since we don't have enough data...
The solution to the problem is as follows:
<span>use the formula:
d = r*t
where:
d = distance
r = rate (or speed)
t = time
</span>
Therefore,
time = distance/speed = 62.5m / 5m/s = 12.5 minutes.
I hope my answer has come to your help. God bless and have a nice day ahead!
She must have a score greater than 69 in her final tests
Let the required score be "x"
<h3>What is Mean?</h3>
The mean of the data is the ratio of the sum to the total sample
Mean = 80+76+85+85+x/5
80+76+85+85+2x/5 > 79
326+x/5 > 79
326 + x > 395
x > 395 - 326
x > 69
This shows that she must have a score greater than 69 in her final tests
