The nearest tenth means 1 decimal place.
so the answer is 8.5
Answer:
17.30 dollars
Step-by-step explanation:
Given that Payton and James mow the lawns.
They do this during summer.
The amount they spend are:
Gas cost = 3.50
Leaf bags = 1.20
Add these to get total costs
Total cost = 4.70
Charge they get per lawn = 22.00
Profit = Revenue - cost
Here revenue per lawn = 22 and cost per lawn = 4.70
Hence profit = 22-4.70 = 17.30 dollars.
Answer is they make 17.30 dollars per lawn.
For example: 35 divided by 5 is 7. So to check with multiplication, just think 7 times 5 is what? 35. This is the same formula for everything.
Hope this helps!!
Answer: 2.5
Step-by-step explanation:
Let 
be the population mean .
Then, Null hypothesis : 
Alternative hypothesis : 
We assume that this is a normal distribution.
Given : Sample size : n=25 , since the sample is small (n<30) so we cannot apply z-test . Thus the test is t-test.
Sample mean : 
Population standard deviation : 
The test statistic for population mean is given by :-
i.e. 
Hence, the observed critical value = 2.5
Answer: We will write ‘3’ in the second space. Therefore, the final number must be 2. 6 ÷ 3 = 2. There is a second way that we could use inverse operations to write this multiplication as a division
