Answer:
a. 81.5%
Step-by-step explanation:
The z-score for 400 is ...
Z = (X -μ)/σ = (400 -500)/100 = -1
The z-score for 700 is ...
Z = (700 -500)/100 = 2
The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...
(1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A
Answer:
90
Step-by-step explanation:
Answer:
(600 miles) / (3 hours) = 200 miles/hour
= 321.8 km/h
50x+40=y for doors galore
40x+60=y for g&h
I can't graph here sorry but hopefully you know how that works
9. 40x+60=50x+40
-40
40x+20=50x
-40x
10x=20
x=2
10. Doors galore because 1 hours equates to 90 while g&h is 100 and so 90>100 then Doors galore is cheaper
