Answer:
The answer is $3000.
Step-by-step explanation:
The men's clothing buyer had a group of 50 jackets priced at $250 each.
Total price of jackets = 
dollars
The buyer reduced the price of the jackets in that group to $200 and 40 jackets were sold.
So, the price for selling 40 jackets is = 
dollars
Remaining jackets =
These were sold at $150 each, totaling to = 
dollars
So, overall money earned by reducing prices both time = 
dollars
And the markdown in dollars = (original price before reducing) minus (educed total price)
= 
dollars
So, the answer is $3000.
Answer:
a) 2.0702
b) 2.07
Step-by-step explanation:
Given:
Sample, n = 840
standard deviation, σ = 60
a) The standard deviation of the sampling distribution, will be:
= 2.0702
Standard deviation of the sampling distribution is 2.0702
b) According to the 68 part of the 68-95-99.7 rule, 68% of all values of x fall within 1 standard deviation on either side of the unknown mean μ.
Therefore, missing number will be:
![1 * [\frac{\sigma}{\sqrt{n}}]](https://tex.z-dn.net/?f=%201%20%2A%20%5B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5D%20)
= 1 * 2.0702
= 2.0702 ≈ 2.07
Answer:
(-1,0)
Step-by-step explanation:
Point B is located one position to the left on the x-axis resulting in a negative x-value in the coordinate pair, and Point B is located 0 units up on the graph resulting in a y-value of 0. Therefore, (-1,0) are the coordinates.

Step-by-step explanation:
y = -3x² + mx + 10
dy/dx = -6x + m.
When dy/dx = 0, -6x + m = 0. => x = m/6.
We have y = -3(m/6)² + m(m/6) + 10 = 37.
=> -m²/12 + m²/6 = 27
=> -m² + 2m² = 324
=> m² = 324
=> m = 18 or m = -18.
