x/ 7 - 1 = 8 -Subtract 1 from 7
x / 6 = 8 -Multiply both sides by 6
x = 48
Check:
48 / 7 - 1 = 8
48 / 6 = 8
8 = 8
Hope this helps!
Answer:
B.
Step-by-step explanation:
Point estimate is always at the center of the interval.
You can find it by averaging the endpoints:
p(hat) = (0.028 + 0.086)/2 = 0.057
1/5+ (-4) is the same as 1/5 - 4
1/5-20/5
-19/5
7.4 is your final answer, hope that help, one decimal place is the first number after the decimal.
Answer:
<h2>Leg length = 8.5</h2><h2 />
Step-by-step explanation:
let x represent the leg length
if we use the Pythagorean theorem we get:
x² + x² = 12²
then
2x² = 12²
Then
x² = 144/2 = 72
then
x = √(72)
=8,485281374239
