So if Angela entered the same restaurant 4 times, we have 4 "instances" of her entering the restaurant.
Each instance, she ordered a salad. The price of this salad is unknown, so we'll say the price is "S".
Each instance, she payed a $5 tip.
So we have 4 instances of spending S, and 4 instances of spending 5.
We know this totals 54.
Knowing all of this information, we can write our equation like this:
4(S + 5) = 54
Divide
S + 5 = 13.50
Subtract
S = 8.50
The cost of salad is $8.50
Answer:
The complement of 44° is the angle that when added to 44° forms a right angle ( 90° ). Subtract 44 from 90.

Answer:
Positive
Step-by-step explanation:
If you multiply both negative, it will always result to positive.
Rule:
+ × + = +
+ × - = -
- × + = -
- × - = +
Total area = area rectangle + area of the triangle
= 8 * 13 + 0.5* 6 * (14-8)
= 122 unit^2
Answer:
The t-value is 2.0049.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 55 - 1 = 54
Now, we have to find a value of T, which is found looking at the t table, with 54 degrees of freedom(y-axis) and a confidence level of 0.95(
). So we have T = 2.0049
The t-value is 2.0049.
