Answer:
Probability is 0.3506
Step-by-step explanation:
We are given
mean is 8mm
so, 
standard deviation is 2.2 mm
so, 
x-varies from 7mm to 9mm
At x=7:
we can use formula
we can plug values
At x=9:
we can use formula
we can plug values
So, z is between -0.45455 and 0.45455
now, we can use normal distribution table
and we get
Probability is 0.3506
Answer:
false
Step-by-step explanation:
the relationship between lengths/dimensions and areas is that areas are created by multiplying 2 dimensions.
when you quadruple (×4) the dimensions, then the areas are growing with the square of the factor (×4×4 = ×16), because the factor goes twice into the multiplication : one time for every dimension involved.
so, quadrupling the dimensions would multiply the areas by 16.
K= -9
Well, h(x) and g(x) both of x^2, so we can disregard that part.
h(x) has +3 and g(x) has -6.
3 - 9 = -6. (Which makes them equal)
g(x) = h(x) + (-9)
x^ - 6 = x^ + 3 - 9
x^ - 6 = x^ - 6
The expected value of playing this game = a weighted average of the winnings (or losses) multiplied by the odds of winning: (3/37)3 + (9/37)2 + (25/37054)(-1) = 9/37 + 18/37 - 25/37 = 27/37 -25/37 = 2/37 = about 0.054 winnings = $0.054 = 5.4 cents
F(x)= 4 lx+6l
f(x)= 4 (x+6)
f(x) = 4x + 24.
Hopes this helps you out.
