To do this you need 94 inches of braid.
<span>94 inches = 2.61 yards
You would need to buy 3 yards so:
$0.60 </span>× 3 = $1.80.
Since you bought 3 yards that would cost $1.80.

Answer:
To use a paired t-test
Step-by-step explanation:
t-tests are essentially tests carried out to compare two different groups to check if there is a major difference in their performances or results which may be related in certain characteristics.
A paired (correlated) t-test is used when there are matched pair of similar units or instances of repeated measurements.
In this case, Mary has to use a paired t-test because the samples (students) have high similarity in characteristics. The students in question has to be from the same class to test her hypothesis (similar characteristics).
Answer:
24 hours
Step-by-step explanation:
Hi,
The equation to represent this situation would be 45x + 720 = 1800
(45 is the cost per hour, x is the number of hours since you don't know how many hours that person was there for. 720 is there because no matter what, you have to pay 720 to visit and = 1800 is the total cost)
Now, solve for x.
45x + 720 = 1800
Subtract 720 on both sides...
45x = 1080
Divide by 45 on both sides...
x = 24
He worked 24 hours that week.
