Answer:
cos (30 deg) = sqrt (3) /2
Step-by-step explanation:
Answer:
We are given:
Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.
Since the alternative hypothesis has less than sign, therefore the given hypothesis is left-tailed
What parameter is being tested?
The parameter used is , which denotes the population mean.
Please note:
The type is test determined based on the alternative hypothesis.
If the alternative hypothesis has sign, it means the hypothesis test is two-tailed
If the alternative hypothesis has sign, it means the hypothesis test is right-tailed
If the alternative hypothesis has sign, it means the hypothesis test is left-tailed
I think it’s D sorry if I’m wrong
Answer:
58+4=62 Sienna’s height is 62 inches
Explanation:
Sienna’s height is 62 inches because Georgia’s height is 58 inches and she is shorter by 4 inches which means you have to add 58+4 which would equal 62.
Answer:
1. The information from the problem illustrates the number of hours flo and bryan works jointly to mow the lawn.
2. The question demonstrates the numbers of hours worked by the two individuals i.e. flo and bryan to mow the lawn. Find the numbers of hours worked i.e h=? by flo and bryan to mow the lawn.
3. H/3+h/6=1
Take LCM i.e. (2H+H)/6=1
Now add H and and move the 6 on the other side and multiply, that becomes
3H=6
Now take 3 on the other side and divide by 6, which becomes the answer i.e. H=2.
4. Variables are H and values are the hours worked.
5. The problem in this question , why the number of hours are missing which we have to find and gives it a sense that how many hours needed to mow a lawn.
6. The time takes for both of them to mow lawn is 2 hours, which is flo works more than bryan to mow a lawn.
7. If you want to check that your anser is correct put the answer in the equation, if both sides come same then the answer is correct, for instance in the same quwstion where answer is H=2. Now put H in the equation i.e.
H/3+H/6=1
2/3+2/6=1
4+2/6=1
6/6=1
1=1
Hence proved. Enjoy :)
