Answer:
7. Ten days were above 70 degrees
8. Approximately 33% of the days were 69 degrees or lower
9. Approximately 8 days would most likely be above 80 degrees
Step-by-step explanation:
The very first thing I did is I put the values in order, ranging from 66 to 85. Then, I counted the number of days where the high temperature was greater than 70 degrees (which ended up being 10).
Five of the days were 69 degrees or lower, so I divided that by fifteen to get 33.33333% (which you can round down as 33%).
Then, as four of these fifteen days had temperatures greater than 80 degrees, I divided four by fifteen and got approximately 26.7%. Multiplying 30 by 0.267, I get 8.01 (which you can just round down as 8).
Answer:
Step-by-step explanation:
sinx = 
The hypotenuse = 25 since 7, 24, 25 ← Pythagorean triple
Hence
sinx =
5.0547x10^8
Is it's scientific notation.
Garden one and two are both unknown, so I am choosing to call garden 2 X and then label garden 1 with comparisons to X.
It is tempting to list:
Garden Two = X
Garden One = X + 9
BUT there is an easier way. We are told that when 3 bushes are taken from garden 2 (x-3) and put in garden 1 (x + 12) then garden one has 1.5 times more than garden two.
Set it up like this:
1.5 ( x - 3) = x + 12 (because 1.5 times garden 2 will give us garden 1)
1.5x - 4.5 = x + 12 (Distribute)
.5x = 16.5 (Use subtraction to move variables to the right and other numb left)
x = 33 for Garden 2
33 + 9 for Garden 1 = 42
