Answer:
C; It would become wider due to using the z-distribution
Step-by-step explanation:
Mathematically, we go on to look at the formula for confidence interval calculations here
The formula involves multiplying z by the s
which is the z-value and the standard deviation
Increasing the standard deviation value means we are increasing the product of multiplying z and s
This means that we are getting a larger value for the multiplication
Thus, we now have a wider confidence interval value as a result of a larger product
So this means that the CI would become wider due to the usage of the z-distribution
Answer:
Yes
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of the lengths of any 2 sides of a triangle must exceed the length of the third side.
8.6+6.6>3.3 is true
6.6+3.3>8.6 is true
3.3+8.6>6.6 is true
Answer:
D
Step-by-step explanation:
18 - 3 = 15
First what you need to do is distribute the properties. Take 2x times the -3 and you will get -1x. Then take the 12 and times it time x and you will get -12x, and then times 12 times 1 which is 12, now here's a fact so you don't get confused, instead of the plus and minus signs it's a negative and positive signs) then you take -1x and -12x and divide them by each other and you will get 12, X=12
