ANTONII [103]
Answer: x=68/11 and y=-72/11


Steps:

2(x+4y=-20)

2x+8y=-40

2x - 3y = 32
- 2x + 8y = -40

-11y=72

y=-72/11


x + 4(-72/11) = -20

x - 288/11 = -20

x=68/11

Answer: No, Store A is charging $2.20 per rose while Store B is charging 2.166667 dollars per rose.

Step-by-step explanation:

11/5 = 2.2

(To check) 2.2 x 5 also equals $11

However, they are not selling roses at the same rate because if you were to do 2.2x6 it will equal 13.2.

13/6 = 2.166667

Suppose that your statistics professor tells you that the scores on a midterm exam were approximately
DedPeter [7]

Answer:

  • Yes

Step-by-step explanation:

z-score representing 85% is 1.04 (from table)

Let x be the score representing the lower limit of 85%.

<u>Use the formula to find z-scores:</u>

  • z = (x - μ)/σ

<u>We have:</u>

  • z = 1.04, μ = 78, σ = 7

<u>Substitute the values and solve for x:</u>

  • 1.04 = (x - 78)/7
  • x - 78 = 7.28
  • x = 85.28

The lower limit of the top 15% is 85.28.

Since your score is greater than 85.28 you earned an A
