Answer:
Step-by-step explanation:
Given that the Acme Company manufactures widgets, which have a mean of 60 ounces and a standard deviation of 7 ounces
We know that 95% of the area lie between -2 and 2 std deviations from the mean.
i.e. Probability for lying in the middle of 95%
Z score 
Between 46 and 74 oz.
b) Between 12 and 57
convert into Z score

P(-6.86<z<-0.43)
=0.5-0.1664=0.3336
c) X<30 gives Z<-4.83
i.e. P(X<30) =0.00
400 divided by 5 = 80.
Needs to bag at least 80.

The base of the prism is a 6 cm square. Any cross section parallel to the base has the same dimensions as the base, so is a 6 cm square. Its area is ...
(6 cm)² = 36 cm²
Total number of people in ward = 16
Number of nurses = 10
Number of male nurses = 4
Number of female nurses = 6
Number of doctors = 6
Number of male doctors = 3
Number of female doctors = 3
We are to find the probability of selecting a female or a doctor.
Probability of selecting a female or a doctor = Probability of selecting a female + probability of selecting a doctor - probability of selecting a female doctor
Probability of selecting a female or a doctor = 9/16 + 6/16 - 3/16 = 3/4
Thus, the probability of selecting a female or a doctor is 3/4
