Answer:
A.
Step-by-step explanation:
Basically.. when you draw a line from the vertex of a right triangle's 90 degree angle to its hypotenuse, it'll make two triangles with the same angles. Then you can use ratios to discern the size of said rectangles. I hope that helps.
Answer:
Average Mean = 1.8
Step-by-step explanation:
Missing:
X:0 1 2 3 4 5 6
P(x): 0.20 0.30 0.20 0.15 0.10 0.05
Computation:
Average Mean [Probability distribution]
∑[P(x) × X]
= 0 x 0.20 + 1 x 0.30 + 2 x 0.20 + 3 x 0.15 + 4 x 0.10 + 5 x 0.05
= 1.8
Average Mean = 1.8
Answer:
<h3><u>8 Km.</u></h3>
Explanation:
- I'm going to turn the fractions into decimals
2 ½: 2.5
3 ⅕: 3.2
- Formula for the area of a parallelogram: A = b(h)
Base: 3.2
Height: 2.5
3.2 · 2.5 = 8
<h3><u>The area of the parallelogram is 8 Km.</u></h3>
45 / 18 as a mixed fraction...
To change the improper fraction to the mixed fraction you have to:-
first divide (as you divide) so that you can get remainder, quotient, divisor and dividend.
i.e 45 is dividend and 18 is divisor.
45 / 18 = 2 9 / 18 where 2 is quotient and 9 is remainder...
so the ans is 2 9 / 18
Answer:
1%
Step-by-step explanation:
Given : You have used the significant level of 0.01 to estimate the average hours of television viewing for the NJ students.
To Find :What is the chance that our interval estimate does not contain the true population mean?
Solution:
We are given that You have used the significant level of 0.01 to estimate the average hours of television viewing for the NJ students.
So, α=0.01
Significance level indicates a risk of concluding that a difference exists when there is no actual difference.
So, The chance that our interval estimate does not contain the true population mean is 0.01
So, The chance that our interval estimate does not contain the true population mean is 
Hence Option D is true
