Answer and Step-by-step explanation:
The statements are not given, but I'll try to analyze the problem to my possible best, so that anyone can understand the problem well.
Matt is owing his sister $300. If he mows lawns after school and on weekends, it means he works 7 days a week.
Since he charges $30 per lawn and gives his friend $10 to help. It means, he earns $20 per lawn. Therefore, every week, he makes $20 x 7 = $140.
If Matt pays his sister half of what he earns per lawn, it means after a week, he will pay her $140 ÷2 = $70.
This means he has to pay $70 for 4 weeks, then pay $10 for 2 days to clear up his debt. This is because, $70 x 4 = $280 and $10 x 2 = $20. Thus, $280 + $20 = $300.
Answer:
100 inches (using the given data)
98.43 (using exact numbers)
Step-by-step explanation:
1 inch = 2.54 centimeters
20 inches = 50.8 centimeters, but for the purpose of answering this question we will assume that 20 inches = 0.5 meters (instead of 0.58).
we must solve the following equation:
20 inches / 0.5 meters = X inches / 2.5 meters
(2.5 meters x 20 inches) / 0.5 meters = X inches
20 inches x 5 = X inches
100 inches = X inches
if we do the exact calculation, 2.5 meters in inches = 250 centimeters / 2.54 centimeters per inch = 98.43 inches
Yes, you can claim that the null hypothesis. But you must pay attention the p-value. If the p-value is higher than the significant value the null hypothesis can't be rejected.
