Second 1 because it isn't negative
Answer:
And if we solve for a we got
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
Step-by-step explanation:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where
and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
As we can see on the figure attached the z value that satisfy the condition with 0.20 of the area on the left and 0.80 of the area on the right it's z=-0.842
If we use condition (b) from previous we have this:
But we know which value of z satisfy the previous equation so then we can do this:
And if we solve for a we got
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
1 pint equals 2 cups. 6 x 2 = 12 plus the other cup (1) is 13
Answer:
13 cups
Answer:
If I'm correct, the answer should be triangle one. Hope I could help, and someone please correct me if I'm wrong. <3
Step-by-step explanation:
I did 6+7 which gave me 13. That should make it a right angle
Answer:
5
Step-by-step explanation:
5x + 2y = 10
2y = 10 - 5x
y = -5/2x + 5
