y = 5
Answer:
Step-by-step explanation:
162, 188, 197, 201, 266
a. add all number: 1014/ 5 = 202.8
b. 266-162 = 104
c. for each number subtract the mean and square the result.
1664.64+219.04+33.64+3.24+3994.24
= 5914.8/5 = 591.48

Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° = 
= 
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x = 
≈ 61.8 ( to the nearest tenth )
Hi,
The total amount is $1,350.
<em /><span><em>So, firstly we'll start off with the easiest one. We know that they bought a cake for </em><em>$250</em><em>. We also know that there were </em><em>50 people </em><em>invited. Appetizers per person cost $2. So we multiply $2 by 50 people. That's $100. They also charge $20 per person for the main course. Now we multiply $20 by 50 people and get $1,000. Now we add $1,000, $250, and $100 to get our total!</em></span>
