Answer:
Profit = 51300 thousand dollars
Explanation:
Cost function in thousands of dollars is given by C(x) = 45 x + 8700, where x represent number of tricycles sold.
Revenue of function R(x) = 75 x
We have the expression for profit = Revenue - Cost
Number of tricycles sold = 2000
Revenue = 75 * 2000 = 150000 thousand dollars
Cost = 45 * 2000 + 8700 = 98700 thousand dollars
Profit = 150000 - 98700 = 51300 thousand dollars
Answer:
Step-by-step explanation:
In the past, mean of age of employees
i.e. 
Recently sample was taken
n = sample size = 60
Mean of sample = 45
Std dev of sample s = 16
(Right tailed test)
Since only population std deviation is known we can use t test only
Std error = 
Mean difference = 45-40 =5
Test statistic t=
df = 60
p value =0.008739
Since p < 0.05 we reject null hypothesis
The mean age has increased.
The legs of an isosceles trapezoids are supplementary, meaning that they are equal to 180 degrees.
7. The smaller number is 7 because 7x5=35
35+1+7=43
