Answer:
a=9.4 b=12.0
Step-by-step explanation:
You need to use Pythagorus
So for a:
8²+5²=89 a=√89=9.4
And b:
17²-12²=145 b=√145=12.0
N(0.05) = t
Multiply the number of pounds times $0.05 per pound find the total they will receive.
4 hours=240 minutes
240 minutes=5 1/3 45 min. intervals
5 1/3 x 6 = 16/3 x 6 = 32
The staff can prepare 32 tables in 4 hours
If you have an average of 97.2 on your current exam and you get a 99 on your next exam, your average will increase.
- Mean in mathematics is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the total number of values.
- To find the average, sum all the values in the set. Then divide the total by the number of values.
We have the current examination mean, xold = 97.2
Now, we receive, x = 99 on the next examination, the new mean will be:
xnew = (xold + x)/N
xnew = (97.2+99)/2
xnew = 196.2/2
xnew = 98.1
The new average is 98.1
98.1 > 97.2
So if you score 99 on your next exam, your average will increase.

Well,
The probability that is least likely to occur is the smallest probability.
0.2
0.5
0.25
0.75
0.2, or 1/5, is the smallest number and therefore the probability which is the least likely to occur.
