Are you sure the question is correct? From a list of integers, if you pick one number, it's guaranteed to be an integer...
Surely there's a condition that you haven't mentioned?
Answer:
She is incorrect
Step-by-step explanation:
If she is doing her math based on her results, she is incorrect. To find out the correct answer, first divide 1000/40 which is 25. Next, multiply 22 and 25. After you do the math, you find that the answer is 550. So based on her results, if she did 1000 trials she would land on heads 550 out of 1000 times.

Step-by-step explanation:$10 per hour, so 10 is multiplied by 9
He gets paid 90 Dollars for one day of work so we would multiply that by Two days.
Step-by-step explanation:
A quadrilateral is made up of four sides. This means the sum of all the side equals 43. This is given as;
(x + 7) + (x² - 2x
) + (x +3) + (2x - 2) = 43
x² - 2x + 4x + 8 = 43
x² - 2x - 35 = 0
Upon solving for x by factorization;
( x - 5) ( x + 7) = 0
The values of x are; 5 and - 7
Since the side of shape cannot have a negative value, -7 is ignored.
x = 5
The length of the sides are;
- X+7 = 5 + 7 = 12
- x² - 2x = 5² - 2(5) = 25 - 10 = 15
- X+3 = 5 + 3 = 8
2x-2 = 2(5) - 2 = 10 -2 = 8
Check:
8 + 8 + 15 + 12 = 43
