3.3 and 3.30 are equivalent to 3.300
I can’t see it it’s to blurry for me
The word commutative comes from commute in in the contacts needs to move around addition and multiplication artery arbitrate operations that are both commutative for addition the rules is a plus b equals b + 8 + example in a number would be 4 plus 2 equals 2 plus for both give 6s results for multiplication the world is a b equals to be a and example in numbers would be 4 times x equals 2x for the result in both cases is a subtraction does not have a commutative property because they be gives a difference result than does be minus a for example for - 2 equals 2 but - -4 equals 92 so in the case of the trash and move in the numbers around produces a different answer each answer in this case is the additive inverse of the other the Venturi operation and voltage subtract is therefore name anticommutativity
Answer:
B. Domain is left to right so the left point is solid on 2 and the right is solid on 8. The solid point means it can also be equal to.
The answers to the questions are:
1. The confidence level is 99 percent.
2. We have to conclude that there is no sufficient evidence available to support this claim because the Confidence interval contains 75 sec.
<h3>How to solve for the confidence level</h3>
1. The confidence level here should be
1- 0.01 = 0.99
= 99 percent
Given that, 99% confidence interval for population mean (μ) is (-34.1 sec u< u < 264.1 ) seconds.
We are to test the claim that the population mean is greater than 75 sec.
2.
The given confidence interval contains the value of 75 sec, so there is not sufficient evidence to support the claim that the mean is greater than 75 sec.
