The 90% confidence interval is (70 - 4, 70 + 4). The margin of error is 4%.
Answer:
x>1
Step-by-step explanation:
move the constant to the right side and change its sign 7x>10-3
Then subtract the numbers 7x>7
Then divide the inequality by 7 from for both sides.
x>1
A.) m=5/6
B.) y
=5/6x-3 use the slope formula y=mx+b
C.) y
-y1 = m(x-x1)
Answer:
42/81 or 0.5185185
Step-by-step explanation:
7/9 × 2/3
The hcf of 9 and 3 is 9
7/9 × 2/3
2/3 × 3= 6/9
7/9× 6/9 = 42/81 or 0.5185185
Answer:
(x - 4)
Step-by-step explanation:
Given x = a is a root then (x - a) is the corresponding factor
Given x = 4 is a root, then
(x - 4) ← is the corresponding factor
Note if x = - 4 is a root , then
(x - (- 4)), that is (x + 4) is the corresponding factor
