Answer:
D. The z- score of the bags is equal to a value of 0.
Step-by-step explanation:
The probability that a normally distributed data with statndard deviation σ and a mean, μ,exceeds a value x, is given by
P(X > x)=1-p(X < x)= 1- P(z<
Now,
Given:
weight of corn chips dispensed into a 14-ounce bag by the dispensing machine is a normal distribution with
mean = 14.5 ounces
standard deviation =0.2 ounce.
So,
If 100 bags of chips are randomly selected the probability that the mean weight of these 100 bags exceeds 14.6 ounces is given by:
⇒ P(X> 14.6)= 1- P(z<
⇒ 1- P(z< 5)=
⇒ 1 - 1 = 0.
Therefore,
The z score of the bags is equal to a value of zero.
Answer:
The expression for two times the difference of eight and d. is
Step-by-step explanation:
To Find:
Write an expression for two times the difference of eight and d.
Solution:
Difference of 8 and d = ( 8 - d )
So One Time Difference of 8 and d = 1× ( 8 - d )
∴ Two Times Difference of 8 and d = 2× ( 8 - d )
The expression for two times the difference of eight and d. is

Answer:
99-12x^3 -50x
Step-by-step explanation:
10t (for tickets) + 6p (for popcorn) = 3000
So, 10t + 6p = 3000
