(4x+1)(2x+3)=8x*2+12x+2x+3
= 8x*2+14x+3
Ok I will let you know tomorrow afternoon when I get to the school
Answer:
41.67 % ( to 2 dec. places )
Step-by-step explanation:
Since 2 dozen cookies were baked, that is 24 and 14 were left.
Then 10 were eaten.
Calculate the percentage eaten as
percentage =
× 100%
percentage eaten =
× 100% ≈41.67%
Answer:
B. (6, 10)
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 8
Standard deviation = 1
Give an interval that is likely to contain about 95% of the sampled cashiers' hourly wages.
By the Empirical Rule, 95% of the sampled cashiers' hourly wages will be within 2 standard deviations of the mean, so from 2 standard deviations below the mean to two standard deviations above the mean
Two standard deviations below the mean:
8 - 2*1 = 6
Two standard deviations above the mean
8 + 2*1 = 10
So the correct answer is:
B. (6, 10)
Answer:
Both the stock have the same expected return.
Step-by-step explanation:
In year 1 the return earned by stocks A and B are:
Stock A = 2% return
Stock B = 9% return
In year 2 the return earned by stocks A and B are:
Stock A = 18% return
Stock B = 11% return
Compute the expected return for stock A as follows:

Compute the expected return for stock B as follows:

Thus, both the stock have the same expected return.
