Answer:
Step-by-step explanation:
55x30=1650 80/2=40 40x30=1200
1650-1200=450 Therefore Eugene has type 450 more words then Allen has
Answer:
The probability that sample mean differ the true greater than 2.1 will be 2.8070 %
Step-by-step explanation:
Given:
Sample mean =46 dollars
standard deviation=8
n=53
To Find :
Probability that sample mean would differ from true mean by greater than 2.1
Solution;
<em>This sample distribution mean problem,</em>
so for that
calculate Z- value
Z=(sample mean - true mean)/(standard deviation/Sqrt(n))
Z=-2.1/(8/Sqrt(53))
Z=-2.1*Sqrt(53)/8
Z=-1.91102
Now for P(X≥2.1)=P(Z≥-1.91102)
Using Z-table,
For Z=-1.91
P(X>2.1)=0.02807
In exponential form: 10^2=3(x+5)
If we were to solve, x=85/3
Answer:
Two lines or shapes that lie exactly on top of each other. Example: these two lines are coincident, only you can't see them both, because they are on top of each other.
Step-by-step explanation:
-4/x^5y^13 because since you have negative exponents on the top you switch them to the bottom
