<u>130 bouquets of 4 red roses and 3 white roses each. Profit is:</u>
- 130*(4*$1.25 + 3*$1) = $1040 > $1000
Option 2
<u>110 bouquets of 3 red roses and 5 white roses each. Profit is:</u>
- 110*(3*$1.25 + 5*$1) = $962.50 < $1000
As we see option 1 is bringing target profit so should be her choice

Answer:
r=60°
Step-by-step explanation:
Both of the angles together make up 90°. we know this because of the red little box denoting 90°.
If one of the angles is 30°, to find the other one, simply subtract 30 from 90.
90-30=60
r=60°
Answer:
The smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.
Step-by-step explanation:
The complete question is:
The mean salary of people living in a certain city is $37,500 with a standard deviation of $2,103. A sample of n people will be selected at random from those living in the city. Find the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income. Round your answer up to the next largest whole number.
Solution:
The (1 - <em>α</em>)% confidence interval for population mean is:
The margin of error for this interval is:
The critical value of <em>z</em> for 90% confidence level is:
<em>z</em> = 1.645
Compute the required sample size as follows:
Thus, the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.
