X is the first value inside the parenthesis and Y is the second value.

You need to find the set that the first number is less than 3 and the second number is greater than 1.

The answer that has both of those is (1,2)

Substitute each value in:

x < 3

y > 1

5 < 3

2 > 1

0 < 3

0 > 1

2 < 3

0 > 1

Answer:

2x
2
128x +640

Step-by-step explanation:

$\displaystyle\frac{8x^2-4x}{4x-2}=\frac{4x(2x-1)}{2(2x-1)}=\boxed{2x}$

$\displaystyle\frac{8x-4}{x+3}-\frac{12x-20}{2x+6}=\frac{8x-4}{x+3}-\frac{4(3x-5)}{2(x+3)}=\frac{8x-4-2(3x-5)}{x+3}\\\\=\frac{8x-4-6x+10}{x+3}=\frac{2x+6}{x+3}=\frac{2(x+3)}{x+3}=\boxed{2}$

$\displaystyle\frac{(2x+10)^7}{(x+5)^6}=\frac{(2(x+5))^7}{(x+5)^6}=2^7(x+5)^{7-6}=128(x+5)\\\\=\boxed{128x+640}$

Answer:

increase

Step-by-step explanation:

Given data is: 71, 67, 67, 17, 69, 84, 21, 87

Arranging in ascending order we find: 17, 21, 67, 67, 69, 71, 84, 87

Here N = 8 (Even number)

N/2 = 4 and N/2 + 1 = 5

4th term = 67, 5th term = 69

-> median = Sum of 4th and 5th term/2 = (67 + 69)/2 = 132/2 = 66

Now, when one of the 67 is replaced by 71, the new data set in ascending order will be: 17, 21, 67, 69, 71, 71, 84, 87

Here, 4th term = 69, 5th term = 71

New median = (69 + 71)/2 = 140/2 = 70

-> new median > initial median

CONCLUSION: Median will increase if the number 71 replaced one of the 67's in the set.

A business bought a lot of 2,500 lamps for 50,000 dollars and wants to sell them at 15 percent profit how much should each lamp

aev [14]

50,000 / 2500 = 20....he bought them for 20 bucks a piece. So if he wants to sell them at 15% profit, he would sell them for 20 + 0.15(20) = $ 23 bucks.

A 15% profit of 50,000 dollars is 0.15(50,000) = 7500. Plus the 50 grand spent totals 57500. So they want to make a $ 7500 profit. Selling 2500 lamps at $ 23 per lamp (2500 x 23 = 57500) makes them their profit.

I should just shut up now...answer is $ 23 per lamp
