Answer:
<em>The cost to manufacture 63 chairs, and that cost is 2268.</em>
Step-by-step explanation:
<u>Mathematical Models</u>
The cost to manufacture x chairs is given as the math model:
C(x)=36x
For example, to manufacture 10 chairs, we write:
C(10)=36*10=360
According to the explained above, the statement C(63)=2268 means we are calculating the cost to manufacture 63 chairs, and that cost is 2268.
Answer:
For a bilateral test the p value would be:
Step-by-step explanation:
Information given
n=225 represent the sample selected
X=87 represent the households with incomes below the poverty level
estimated proportion of households with incomes below the poverty level
is the value that we want to test
z would represent the statistic
represent the p value
System of hypothesis
We want to check if the true proportion is equal to 0.32 or not.:
Null hypothesis:
Alternative hypothesis:
The statistic is given bY:
(1)
Replacing we got:
For a bilateral test the p value would be:
Answer:
ROI = 66.67%
Step-by-step explanation:
Given:
josh investment= $12,000
Received sum= $20,000
ROI=?
ROI is the return on investment that gives the loss or gain in any investment and is calculated by the following formula:
ROI= (interest/investment) x 100
Finding interest:
interests= received sum- investment
= 20,000-12,000
=8000
Putting values in ROI formula we get:
ROI= (8000/12000) x 100
= 66.67%
Hence the return on investment is 66.67%!
The equation :
6x - 10 = 32
the number
x = 7
