<span>the proccess of choosing is independent so probability of choosing from machin1 is:300/1000 =0.3
choosing from machin2 is:707/1010=0.7
the total result is 0.3*0.7=0.21 ;</span>
Answer:
B = 2
Step-by-step explanation:
Pull out like factors:
16b - 32 = 16 • (b - 2)
16 • (b - 2) = 0
Solve: 16 = 0
Solve: b-2 = 0
B = 2

603/25=24 and 3/25 (mixed number)
24.12 (decimal)
You can isolate y on both sides, getting:
2x-17=y and x-10=y
Then, make the two y equal each other, and solve the equation
2x-17=x-10
The answer would be x=7.
then, plut in the amount into one of the equations:
x-y=10
7-y=10
y=-3
T
Therefore, the answer is x=7 and y = -3, or (7,-3)

a^2=b^2+c^2
a=41 inches
b=40 inches
