5p-9=2p+12
+9 +9
5p= 2p+21
-2p -2p
3p/3=21/3
p=7
We are given with
x = 15%
n = 14
and asked to get the probability that none are turned to the show
u = 0
Using the formula for the z-score
z = x - u / s
where x and u are given
s is supposed to be given as well
If there is a value of s, substitute the values and solve for z
Then, refer to the z-score table (one-tailed) to determine probability basin on the z-score.
Answer:
There is a 3/5 chance of the first ball being white, and a 3/10 chance the second one is black.
Step-by-step explanation:
There are 5 balls, of which 3 are white, so you have a 3/5 chance of the first one being white. Then you have 2 white and 2 black balls. There is a 2/4 chance of picking a black ball. Multiply 3/5 and 2/4 to get 6/20, or 3/10 for choosing a white ball then a black ball.
648 divided by 8 is 81.
64 goes into 8 8 times (8*8)
8 goes into 8 1 time (8*1)
Let x = the length of the triangle's hypotenuse
using proportions, this is what the equation looks like:
cross multiply to get:
divide both sides by 45 to get
x=12
