Answer:
And replacing the value obtained we got:
And if we solve for a we got
Step-by-step explanation:
Let X the random variable that represent the average home prices 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)
We want to find a value who accumulate 0.10 of the area on the left and 0.90 of the area on the right of the normal standard distributon and for this case it's z=-1.282
And using the distribution for the sample mean we can do this:
And replacing the value obtained we got:
And if we solve for a we got
First convert gallons to quarts (9x4= 36) subtract the quarts (36-10=26) so you have 26 quarts, now convert the 3 gallons to quarts (3x4=12) now subtract (26-12= 14) there are 2 pints in one quart so convert quarts to pints (14x2=26) Your answer is 26
Answer:
My earlier answer was deleted, so I'm reposting. The only thing I can think happened is that I included a link to a free bar chart program, which I used for the attached chart.
Step-by-step explanation:
Make your own chart or find an online bar chart utility. I was unable to properly label the title and axes on my chart, so modify these properties.
3x-10y=-25
4x+40y=20
12x-40y=-100
12x+120y=60
-160y=40
y=1/4
x=5/2
I reccomend the search bar up at the top ("What is your question") before you ask questions, to make sure they're not already answered.
There is a formula d = rt, distance = rate*time. So
r = d/t.
r = 7mi/55min = 0.127mi/min
Or another way to see this:
