Answer: the costs would be the same if he orders 29 rose flowers.
Step-by-step explanation:
Let x represent the number of roses that Victor would order such that the cost will be the same with either flower shop.
Dayton Florist charges $3 per rose, plus $12 for the vase. This means that if he orders x rose flowers, the total amount that he would pay is
3x + 12
Tammy's Flowers, in contrast, charges $2 per rose and $41 for the vase. This means that if he orders x rose flowers, the total amount that he would pay is 2x + 41
For the costs to be the same, the number of rose flowers that he orders would be
3x + 12 = 2x + 41
3x - 2x = 41 - 12
x = 29
b is the awnser
Step-by-step explanation:
Step-by-step explanation:
3x+12=45
3x=45-12
3x=33
3x/3=33/3
x=11
2/8 is simplified to 1/4 and 1/2 can be changed to 2/4 and 0 is 0/4 and 1 is 4/4 so It can’t be 1 and I t can’t be 0 so the answer is *******1/2******
Answer:
a) 5.6 years
b) 0.4478
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 5.6 years
Standard Deviation, σ = 1.9 years
Sample size, n = 18
We are given that the distribution of amounts of time is a bell shaped distribution that is a normal distribution.
a) Mean of each sample.
The best estimator of the sample mean is the population mean itself. Thus, we have:
Thus, the sample mean is 5.6 years.
b) Standard error
Formula:
Putting values, we have.
Thus, the standard error is 0.4478.
