M=-3.5+2t, R=-3t when they meet M=R so
-3.5+2t=-3t
-3.5+5t=0
5t=3.5
t=0.7 hrs (42 minutes)
Answer: - 84/3

Answer:
x = g + y - C
Step-by-step explanation:
<u>Step 1: Add y to both sides</u>
g + y = C+ x - y + y
<em>g + y = C + x</em>
<em />
<u>Step 2: Subtract C from both sides</u>
g + y - C = C + x - C
<em>g + y - C = x</em>
<em />
Answer: x = g + y - C
Answer:
24 ft sq
Step-by-step explanation:
find area of triangles
6×4=24
24/2=12
add areas together
12+12=24
Answer:
The normal distribution is explained for the solution of this question.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean = 25, Standard Deviation = 3.8
This means that 
So


If P(X > k) = a
We have to find
when Z has a pvalue of 1 - a.
If P(X < k) = a
We have to find
when Z has a pvalue of a.
