In the same set of 1,000 integers from 1 to 1,000, an integer chosen at random on a single trial should be an integer from 1 to

25 about 25 out of every 1,000 trials, or one out of every 40 integers selected. How many integers between 1 and 25 would you expect to appear in a sample of 80 trials?
A. A sample of 80 integers would be expected to have no integers from 1 to 25.
B. A sample of 80 integers would be expected to have two integers from 1 to 25.
C. A sample of 80 integers would be expected to have four integers from 1 to 25.

Reminder: Don't post nonsense answer like "nweudnne" for points or ill do it right back at you and explain your answer.

prisoha [69]
Slope = (2+4)/(1-4) = 6/-3 = -2
passing thru (1.2)
y = mx + b
b = y - mx
b = 2 - (-2)(1)
b = 2 + 2
b = 4

Error Analysis: George was trying to rearrange the formula below to slope-intercept form, y = mx + b. by
Nat2105 [25]

Answer:

George's mistake would be:

Instead of 2x + 40, she has made - x + 20.

Step-by-step explanation:

Slope - Intercept Form = y = mx + b

y + 20 = 2(x +20)

y + 20 = 2x + 40

   - 20          - 20

----------------------

y = 2x + 20

(Should have been the answer)

BUT,

George's Solving:

y + 20 = 2(x + 20)

y + 20 = -x + 20

George's Mistake would be her miscalculation during her 2nd step. Where instead of distributing 2 to (x + 20), she has changed it to -x + 20, when in reality, it should have been 2x + 40.
