So, we have
<span>Z=<span><span>x−μ / </span>σ
</span></span><span>Mean would be = 56
30 - 56 = |-26|
4
3 - 56 = |-13|
and
Standard deviation= 13
</span><span>2 - 1 will give us the approximate area
95/2 - 68/2 = N
95
-68 = 27
27 /2 = 13.5
</span>Hence, the answer would be
<span>800,000 * .135
</span>= <span> 108000</span>
Answer:
Length = 37 feets
Width = 44 feets
Step-by-step explanation:
Given that :
Length = l
Width, w = 7 + l
Perimeter , P of rectangle = 162
Recall:
Perimeter of a rectangle = 2(l + w)
P = 2(l + w)
162 = 2(l + (7 + l))
162 = 2(l + 7 + l)
162 = 2(7 + 2l)
162 = 14 + 4l
162 - 14 = 4l
148 = 4l
l = 148 / 4
l = 37 feets
Width = l + 7
Hence,
Width = 37 + 7 = 44 feets
Yep his right and it is shown to me good
If x=3 then the f(x)=4
If x=6 then the f(x)=7
If x=7 then the f(x)=8
A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- score is 0.40.
Answer: The given z-score is false.
Explanation: We are given:
Mean, 
,
Variance, 
The z-score formula is given below:
Therefore, the z-score corresponding x=100 is 2
Therefore, the given z-score = 0.4 is false.
