Answer:
c=y×z
Step-by-step explanation:
the answer is this because z would be the number of dozens you have times y the cost of one by multiplying those together you will get the cost of the z dozens of eggs
Payment on Plan A = $300
x is the number of hours Jake works.
Payment on Plan B = Fixed charges + (charge per hour) × (number of hours worked)
= $150 + $6.25(x)
= 150 + 6.25x
Since, the payment on Plan B should be more than Plan A,
150 + 6.25x > 300
6.25x > 300 - 150
6.25x > 150
x > 24
The minimum vale for x which satisfies this inequality is 25.
Hence, x = 25.

Answer: (0.4356,0.4844)
Answer:
The answer is -0.71666666666 in decimal form.
In fraction form it is -43/60.
Step-by-step explanation:
Answer:
B. the results are not statistically significant at level = 0.05, but they are practically significant.
Step-by-step explanation:
Given that the average Math SAT score for all students taking the exam this year is 480 with standard deviation 100.
Sample size n =4
mean difference = 550-480 = 70
Std error of sample =
Since sample size is small t test can be done with df =3
(one tailed test)
t =
p value =0.128
Since p >0.05 we accept null hypothesis.
B. the results are not statistically significant at level = 0.05, but they are practically significant.
