Answer:
Step-by-step explanation:
Answer:
A) 90.32%
B) 90.11%
C) 81.546 miles per hour
D)77.93%
Step-by-step explanation:
Given data:
speed = 73.7 miles/hour
standard deviation = 4.77 miles /hour
a) 
= P (z< 1.31)
= 0.90320 = 90.32%
b) 
= P (-2.872< z< 1.31)
= P (z<1.31) - P(z<-2.87)
= 0.90320 - 0.00205
= 0.90115 = 90.11%
c) P(X <X) = 0.95
z = 1.645
x = 81.546 miles per hour
= P (z> -0.775)
= 0. 0.7793 = 77.93%
Answer:
Least to greatest should be 1 over 6, 1 over 3, and then 2 over 5. least to greatest with the same denominator should be 5 over 30, 10 over 30, and 12 over 30
Step-by-step explanation:
First step is to find the common denominator, which is 30. Then you want to figure out how you got to 30 and multiply that by nominator. after you have that all complete, then just sort from least to greatest. To listed from least to greatest is you take the smallest number, for example which would be 5 over 30 and then sorts continuously from the greater number as well, which would be 12 over 30
Answer: Area is 426
Step-by-step explanation: Do 15 x 26 which is 390 to find out the rectangle part, and the area for a triangle is 1/2 (b x h) so 9 x 8 is 72 and then divide by 2 is 36 so 390 + 36 is 426
