Answer:
First you find the difference in temperature. Final temperature minus initial temperature. -43-17=-60 So for every 300m temp will minus 2C.
There's a difference of -60, how many -2 is in -60? So -60÷(-2)= 30. 30 times 300m = 9000m or 9km.
It would be j because you would subtract 25 because he sold 25 pieces then divide by 40 to find the number of piles
Answer:
29
Step-by-step explanation:
The right triangle is isosceles triangle so we have the left angle of it is:
180-64=116
116÷2=58
Then start to calculate the left triangle angles:
180-58 = 122
180-122 = 58
58÷2 = 29
5. 5x-5
. ------------------
. 10x²-25x+15
We can first factor 10x²-25x+15, it will turn into (2x-3) and (5x-5)
(if you need help on factoring, please leave a comment)
So the question will be like:
. 5x-5
. ---------------
. (2x-3)(5x-5) The factored answer is the same as the original . number, so the factor answer can replace it.
We know 5x-5 on the top and 5x-5 on the bottom is the same, so they can cancel out, and it will become:
2x-3=0
Then solve
2x-3=0
2x=3
x=2/3

Answer:
P(X>4)= 0.624
Step-by-step explanation:
n = 10
p= 0.5 ,q= 1 - p = 0.5
Two fifth of 10 = 2/5 x 10 =4
It means that we have to find probability P(X>4).
P(X>4)= 1 -P(X=0)-P(X=1)-P(X=2)-P(X=3)-P(X=4)
We know that
P(X>4)= 1 -P(X=0)-P(X=1)-P(X=2)-P(X=3)-P(X=4)
P(X>4)= 1 -0.0009 - 0.0097 - 0.043 - 0.117-0.205
