Eight randomly selected customers at a local grocery store spent the following amounts on groceries in a single visit: $216, $184, $35, $92, $142, $175, $9, and $57. Let yi denote the amount spent on groceries by a single customer in a single visit. Find the following (give the answers without commas):
a. ∑y
b. (∑y)^2
c. ∑y^2
Answer:
a) 910
b) 828100
c) 144320
Step-by-step explanation:
a. ∑y
This is the sum of all values of y. So
[tex]\sum y = 216 + 184 + 35 + 92 + 142 + 175 + 9 + 57 = 910[/tex]
b. (∑y)^2
This is the square of the sum, so the square of 910, that we found in the previous item.
910² = 828100
c. ∑y^2
This is the sum of the squares of each amount spent. So
[tex]\sum y^2 = 216^2 + 184^2 + 35^2 + 92^2 + 142^2 + 175^2 + 9^2 + 57^2 = 144320[/tex]

Answer:
y = 2x - 10
Step-by-step explanation:
Slope-intercept form is...
y = mx + b
To get the slope, you have to use the formula...
(y2 - y1) / (x2 - x1)
In this case,
y2 = 2
y1 = 10
x2 = 6
x1 = 10
So...
(2 - 10) / (6 - 10)
= -8 / -4 = 2
Therefore, slope is 2
y = 2x + b
Using any of the two x and y value provided, input the values in the equation
(I'm going to use 6,2)
2 = 2(6) + b
2 = 12 + b
b = -12 + 2
b = -10
Put this all together...
y = 2x - 10
Hope this helps :)

Answer:
12, 17, 30.
Step-by-step explanation:
Given
(a) to (d)
Required
Which cannot represent a triangle
The rule to use is:
[tex]a + b > c[/tex]
So, we have: 12, 17, 30.
[tex]12 + 17 > 30[/tex] ===> [tex]29 > 30[/tex] --- False
[tex]12 + 30 > 17[/tex] ==> [tex]43 > 17[/tex]
[tex]17 + 30 > 12[/tex]
Because, one of the inequalities is False, then this can not represent the sides of a triangle.

Solve 1/11c > 9. Graph the solution. . The solution is
Answer:
I suppose that the inequality is:
(1/11)*c > 9.
To solve this we need to isolate c in one side of the inequality.
To isolate it, we need to multiply both sides by 11, then we get:
11*(1/11)*c > 9*11
c > 9*11 = 99
c > 99.
To graph this, we will have an open dot at c = 99, and an arrow that points to the right direction.
The graph is shown below.
8.15 = e + 6* the answer would be E=2.15 right if it’s not plz correct me if I’m wrong
