X=9 beecause 135-20 =115 and 130 is bigger than 130
The point estimate would be 2.25%.
Confidence intervals are centered around a point estimate; that is, the point estimate is in the very middle of the confidence interval. We can find the point estimate by averaging both ends of the confidence interval together:
(1.1+3.4)/2 = 2.25.
Answer:
Step-by-step explanation:
A.) 2a+4b-c: Replacing a with 2, b with 3 and c with 4, we get:
2(2) + 4(3) - (4) = 4 + 12 - 4 = 12
B.) 6(a+c)-b: Replacing a with 2 and c with 4, we get 6(2 + 4) - 3.
The work inside parentheses should be done first, resulting in 6(6) - 3.
This comes out to 33.
Yes it is an exponential function as the value of y increases exponentially as x increases.
Answer:
17/8
Step-by-step explanation:
Step 1: Multiply the whole number part (2) by the denominator (8).
2 × 8 = 16
Step 2: Add the product from Step 1 (16) to the numerator (1).
16 + 1 = 17
Step 3: Write that result (17) above the denominator. So,
2 1/8
= 17/8
