(a) P(x > 12) ≈ 0.4013
About 40% of the fish are longer than 12 inches.
(b) 300*P(x < 7) ≈ 48
about 48 of 300 fish could be expected to be shorter than 7 inches.
Multiplicative Identity Property.
Answer:
y =1/3x+20
Step-by-step explanation:
He starts 20 minutes late so we need to add 20 minutes to the time
He travels 3 times faster so he takes 1/3 of the normal time x
y =1/3x+20
Answer:
The means differ by 1, but the ranges differ by 40.
Step-by-step explanation:
The mean for LaTesha's score is (92+45+67+36+80)/5= 64
The mean for Benards score is (63+68+62+69+53)/5= 63
The range for LaTeshas score is 92-36=56
The range for Benards score is 69-53=16
So, 64-63=1 and 56-16= 40
