Answer:
alpha=0.01
Step-by-step explanation:
confidence level = 1 - alpha
so alpha = 1 - confidence level = 1 - 0.99 = 0.01
In statistics, alpha represents the value that checks the test statistic in order to determine if it is significant or not. In other words, alpha is the acceptable margin of type 1 error. Alpha is also called the significance level, which opposes the confidence level. Significance level + confidence level = 1.
Answer:
62
Step-by-step explanation:
divide 29 by 42 and multiply the answer by 100
20^2 = 12^2 + x^2
400 = 144 + x^2
-144 on both sides
256 = x^2
Find square root of 256.
x = 16
Answer:
<em>404</em>
Step-by-step explanation:
Given the expression
g(x) = 2x and h(x) = x^2 + 4
Find hoh(-4)
First we need to find (hoh)(x)
(hoh)(x) = h(h(x))
h(h(x)) = h(x^2+4)
h(x^2+4) = (x^2+4)²+4
h(x^2+4) = x⁴+8x²+16 + 4
h(x^2+4) = x⁴+8x²+20
h(h(x)) = x⁴+8x²+20
when x = -4
h(h(-4)) = (-4)⁴+8(-4)²+20
h(h(-4)) = 256+128+20
h(h(-4)) = 404
<em>Hence hoh(-4) is 404</em>
