The answer is given below
Step-by-step explanation:
a. We will <u>always </u>find a significant difference by switching to an alpha level of .1 with the same sample results.
b. We will <u>sometimes</u> find a significant difference by switching to an alpha level of .01 with the same sample results.
c. We will <u>sometimes</u> find a significant difference by switching to an alpha level of .001 with the same sample results.
d. We will <u>always</u> find a significant difference by switching to an 80% confidence interval with the same sample results.
The answer is 11.6666666667 I believe
Let the two numbers be x and y with x being the greater number.
Given,
x = 7 + y
Also given,
x + y = 39
Substituting the value of x from above,
7 + y + y = 39
7 + 2y = 39
2y = 39 - 7
2y = 32
y =
y = 16
x = 7 + y
x = 7 + 16
x = 23
Hence, the two numbers are 23 and 16.
Answer:
Step-by-step explanation:
for a lot of math classes they just tell you "don't take the square root of a negative number" Then when you see this it looks all wrong. But, just think of the two things under the radical as
now, take the -1 out of the square root as " i "
i
and if you want to put it into correct complex form
0 + i
