The designer must sell 200 hats for breaking even.
Step-by-step explanation:
Given,
Cost for material for each hat = $5.50
Selling price of each hat = $12.50
Cost spend on advertising = $1400
Let,
x represents the number of hats.
Revenue = 12.50x
Costs = 5.50x+1400
For breaking even,
Revenue = Cost

Dividing both sides by 7

The designer must sell 200 hats for breaking even.

Answer:
y=-5
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are equal and bisect each other
so

step 1
Find the value of x
substitute the given values

solve for x
Multiply by 2 both sides


step 2
Find the value of y

we have


substitute

substitute the value of x

Answer:
Sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.
Step-by-step explanation:
To yield a more accurate estimate of the population mean, margin of error should be minimized.
margin of error (ME) of the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic in the given confidence level(z-score or t-score)
- s is the standard deviation of the sample (or of the population if it is known)
for a given confidence level, and the same standard deviation, as the sample size increases, margin of error decreases.
Thus, random sample of 50 people from population A, has smaller margin of error than the sample of 20 people from population B.
Therefore, sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.
