Answer:
The appropriate solution is "825".
Step-by-step explanation:
Given that,
Total observations,
= 5,500
Relative frequency,
= 0.15
As we know,
⇒
or,
⇒
By putting the values, we get
⇒
⇒
Multiply -0.25(10) and 0.5(5)
Add -0.25 and 0.25
4-0=4
Just subtract each power of m and n, subtract the bottom from the top. You can not do this to 2^3 and 4^2 because they had different bases. Expanding, you get that 2^3=8 and 4^2=16.
Therefore, the numbers cancel out, leaving a 2 in the denominator.
For m, 4-5=-1, which means the variable m is on the denominator.
For n, 3/2-1/2=1, which means it is on the numerator.
So, simplifying this expression gives you n/2m.
Answer:
0.9719
Step-by-step explanation:
Find the mean and standard deviation of the sampling distribution.
μ = 5.1
σ = 1.1 / √49 = 0.157
Find the z score.
z = (x − μ) / σ
z = (4.8 − 5.1) / 0.157
z = -1.909
Use a calculator to find the probability.
P(Z > -1.909)
= 1 − P(Z < -1.909)
= 1 − 0.0281
= 0.9719
93 x 2 = 186
12 x 4 = 48
186 + 48 = 234
1240 - 234 = 1006 feet left.
