2. How many integers between 1 and 25 would you expect to appear in a sample of 80 trials? Explain.
3. The following integers from 1 to 25 appeared when a sample of
50 integers was taken from the list of the integers from 1 to 1,000.
12, 21, and 16
Is this sample of 50 trials more or less than what was expected
for the population as a whole? Explain.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: y = -2.5x - 15

              (-6,0)
