Answer:
440 pounds
Step-by-step explanation:
Ratio is basically "parts".
We have ratio of 4:3:4, that is a total of 4 + 3 + 4 = 11 parts
The apple is 4 parts and total amount is 160 pounds. So each "part" is:
160/4 = 40 pounds
The total pounds of all 3 fruits is 11 parts * 40 pounds per part = 11 * 40 = 440 pounds
hence,
Truckload of fruits weigh at 440 pounds
1,3,7 are true. 5 is false.
Answer:
99.73% of bags contain between 62 and 86 chips .
Step-by-step explanation:
We are given that the number of chips in a bag is normally distributed with a mean of 74 and a standard deviation of 4.
Let X = percent of bags containing chips
So, X ~ N()
The standard normal z score distribution is given by;
Z = ~ N(0,1)
So, percent of bags contain between 62 and 86 chips is given by;
P(62 < X < 86) = P(X < 86) - P(X <= 62)
P(X < 86) = P( < ) = P(Z < 3) = 0.99865 {using z table}
P(X <= 62) = P( <= ) = P(Z <= -3) = 1 - P(Z < 3)= 1 - 0.99865 = 0.00135
So, P(62 < X < 86) = 0.99865 - 0.00135 = 0.9973 or 99.73%
Therefore, 99.73% of bags contain between 62 and 86 chips .
