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.

The area of a rectangular wall of a barn is 32 square feet. It’s length is 4 feet longer than the width. Find the length and wid
Gnom [1K]

Answer:

Step-by-step explanation:

Givens

Area = L * w

w = x

l = x  + 4

Area = 32

Solution

32 = x(x + 4)

32 = x^2 + 4x

x^2 + 4x - 32

(x + 8)(x - 4)

Only x - 4 is going to make any sense

x - 4 = 0

x = 4

The width is 4

The length is 4 + 4 = 8

4*8 = 32 which is the area.
