1 answer:
Answer:
Step-by-step explanation:
(a)
3 ft long when divided into half ft each will be
3ft ÷1/2 ft
We change the ÷ to × then the second part is reciprocated hence
3ft÷1/2= 3ft×2/1=6 pieces
(b)
The question requires us to get the differences. Initially, Phil makes 3 quarts of soup but the family takes only half of the original quantity to mean Phil remains with the other half.
Therefore, half of 3 is 3×1/2=3/2= 1.5 or 1 1/2
(c)
Hiding 3 pounds of gold into two equal sections means 3 is divided by 2
3÷2=1.5 or 1 1/2
(d)
If half, 0.5 represent 3 cups then full quantity represent x
0.5=3 cups
1=x
By cross multiplication
1*3/0.5=6

Answer:
There is not enough evidence to conclude that average starting salary for clerical employees in the state is less than $35,000 per year.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 35,000 dollars per year
Sample mean, = 34,700 dollars per year
Sample size, n = 100
Alpha, α = 0.10
Population standard deviation, σ = 3,500 dollars per year
First, we design the null and the alternate hypothesis
We use one-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to conclude that average starting salary for clerical employees in the state is less than $35,000 per year.
