Answer:
0.45576
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Standard Deviation = √variance
Mean = 50
= √9
= 3
z = 51 - 50/3
= 0.11111
Probability value from Z-Table:
P(x<51) = 0.54424
P(x>51) = 1 - P(x<51)
= 1 - 0.54424
= 0.45576
The probability that the dealer will sell 51 or more cars is 0.45576
Answer:Decreasing the distance between the objects
Step-by-step explanation:
Answer:
8x² + 6xy - 4
Step-by-step explanation:
(5x² + 4xy - 7) + (3x² + 2xy + 3) ← remove parenthesis
= 5x² + 4xy - 7 + 3x² + 2xy + 3 ← collect like terms
= 8x² + 6xy - 4
