Answer:the function representing profit, P = 3n + 200
Step-by-step explanation:
The function C = 2n + 200 represents his costs, in dollars, for producing n jars of salsa.
The revenue, or the amount he receives for selling n jars, can be represented by the function R = 5n.
Profit = revenue - cost or expenses.
Therefore,
The function representing Dominic's profit, P, for selling n jars of salsa will be
P = 5n - 2n + 200 = 3n + 200
1. 9 1/2
2. 30 3/5
3. 6 2/5

5. 10 1/8
Answer:
The correct answer is - 97.74%.
Step-by-step explanation:
Given:
sample mean = 281
Std Dev = 47 ==> Sample
Std Dev (s) = std dev/sqrt(n) = 6.0677
Solution:
Find : P( x > 268 )
z = ( x - u )/s = ( 268 - 281 )/6.0677
= -1.9558
then, P( x > 270) = P( Z > -1.9558)
= P( Z <1.9558)
= 0.9747
change into percentage:
= 97.471%
Answer:
Confidence interval for the population proportion of women fearing from breast cancer are 61%
Step-by-step explanation:
Point estimate of the proportion of the population of women who feared from breast cancer is:
β=61%
Standard error of the estimate:
Se= 0.154
Margin of error for 90% confidence interval for the population proportion:
0.254
90% confidence interval for the population proportion will be
(0.5846,0.6354)
Answer:
Step-by-step explanation:
(a) When two quantities vary inversely, their product is the constant of variation:
d = k/c → cd = k
For d=17 and c=2, k = 2·17 = 34
Then the equation can be written as ...
cd = 34 . . . or . . . d = 34/c
__
(b) d = 34/68 = 1/2 . . . . . put c=68 into the above equation to find d
For c=68, d=1/2.
