Answer:
c
Step-by-step explanation:
Answer: The correct option is first, the number of basketball hoops did the company previously produce to make the same profit is 1.3 million hoops.
Explanation:
Let the number of basketball hoops did the company previously produce to make the same profit be x.
Total Revenue = Price * Quantity
The total revenue in million dollars is,
The total cost in million dollars is,
Total Cost = One unit cost * Quantity
Profit = Total Revenue - Total Cost
The profit is 15 million.
The value of x is 1 and 
.
The production is always positive therefore the value of x either 1 or 1.3. Since 1 million is not available in the options therefore the the correct optin is 1.3 million hoops.
Answer:
h = 13
Step-by-step explanation:
Given the area of a triangle as 84.5 .
The correct value to complete the formula to calculate for the height h is 13 .
Area of a triangle = 1/2 b x h
b = base
h = height
Using the above formula
84.5 = 1/2 x 13 x h
84.5 = 13/2 x h
84.5 = 6.5 x h
84.5 = 6.5h
Divide both sides by 6.5 to get h
84.5/6.5 = 6.5h /6.5
13 = h
h = 13
Assuming all of them had the same amount at the start
Answer:
Here we have given two catogaries as degree holder and non degree holder.
So here we have to test the hypothesis that,
H0 : p1 = p2 Vs H1 : p1 not= p2
where p1 is population proportion of degree holder.
p2 is population proportion of non degree holder.
Assume alpha = level of significance = 5% = 0.05
The test is two tailed.
Here test statistic follows standard normal distribution.
The test statistic is,
Z = (p1^ - p2^) / SE
where SE = sqrt[(p^*q^)/n1 + (p^*q^)/n2]
p1^ = x1/n1
p2^ = x2/n2
p^ = (x1+x2) / (n1+n2)
This we can done in TI_83 calculator.
steps :
STAT --> TESTS --> 6:2-PropZTest --> ENTER --> Input all the values --> select alternative "not= P2" --> ENTER --> Calculate --> ENTER
Test statistic Z = 1.60
P-value = 0.1090
P-value > alpha
Fail to reject H0 or accept H0 at 5% level of significance.
Conclusion : There is not sufficient evidence to say that the percent of correct answers is significantly different between degree holders and non-degree holders.
