Answer:
We conclude that there is not enough evidence to support the claim compute technique performs differently than the traditional method.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 101 hours
Sample mean, =100 hours
Sample size, n = 140
Alpha, α = 0.01
Population standard deviation, σ = 6 hours
First, we design the null and the alternate hypothesis
We use Two-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
The calculated z statistic lies in the acceptance region, we fail to reject the null hypothesis and accept it.
We conclude that there is not enough evidence to support the claim that compute technique performs differently than the traditional method.
Multiply tan(26°1') by 205 to find h; then, divide 205 from h to see if the answer is tan(26<span>°1). If it is, the answer is correct; if not, try again- - perhaps you typed in the numbers wrong.</span>
Answer:
It's a isosceles triangle........
I hope this is right....
Step-by-step explanation:
Ok. First of all, we need to follow the order of operations: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. We don't have any parentheses, exponents, or division to resolve, so you can skip those. So now you have: Multiplication, Addition, and Subtraction. We have multiplication in each term, but each term is fully simplified, so we have Addition and Subtraction left.
With that out of the way, let's go ahead and rearrange this equation so it is easier to solve. (<em>Note: we can only rearrange terms that are positive because subtraction is not commutative. But we can turn negative terms into "positive" terms by the method shown below.</em>)
4a - 7b + 2ab - a + b
4a + (-7b) + 2ab + (-a) + b (<em>Now the terms are all positive, so we can rearrange them, but they still have the same value.</em>)
4a + (-a) + 2ab + (-7b) + b
3a + 2ab + 7b
And there we go. Our answer is fully simplified. If you can understand this, you'll be able to simplify without isolating and rearranging the terms each time.
Hopefully this was helpful and not confusing.
Answer:
just take the whole number (1) times the denominator (18) plus the numerator (7)
therefore: 1*18 = 18
18+7 = 25/18
