Answer: C.
Step-by-step explanation: 3+2+2+12+6+5+14+4=48 divided by 8 equals 6
If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );
Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)
Therefore:
(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10
(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15
Answer; the other endpoint of a line will be (10,15)
Answer:
(a) z=-0.59
(b) Joe will invest in Mean Corporation. The probability of getting an annual return grater than 11% is 72.3%.
Step-by-step explanation:
We have a normal distribution for the annual return of the stock.
This distribution has mean of 13.9% and s.d. of 4.9%.
If X=11%, we can calculate its corresponding z-value as:
The z-value is z=-0.5918.
The probabilty of P(X>11%)=P(y>-0.5918) is, by the standarized normal distribution table, equal to 0.723.
As its P(y>-0.5918)=P(X>11%)=0.723 bigger than the 70% threshold, Joe will invest in Mean Corporation.
The correct answer is B) the cost of removing 80% of pollutants is $196,000.
Using the equation, we have
240(80)/(100-80) = 240(80)/20 = 196
Since this is in thousands of dollars, we have 196,000.
Using the equation, A is not correct; it would be 160,000.
The vertical asymptote would be at 100%.
B must be the correct answer.
