Answer:
<h2>12.1% profit</h2>
Step-by-step explanation:
Given data
total eraser= 87
cost =$3 each
Total cost of eraser= 87*3= $261
she sold 63 at $3.5
1. sales made for the 63= $220.5
2 sale made for the remaining= 87-63=24
24*3=$72
Total sales made = 220.5+72=$292.5
her profit= sales-cost
profit= 292.5-261=$31.5
therefore the percent profit is
=31.5/261*100
=0.12*100
=12.1%
Answer:
Option B.
Step-by-step explanation:
In a regression of y in x, the proportion oh the variation in y explained by the variable x is shown in the R-squared value. So, for answering this question we need to look at the R-squared of such regression.
In this case the R-squared is 98.9% (or 0.989), so we will the option that matches this value. Looking at your options, the one that matches the R-squared is option B.
So, B is the correct option.
Answer:
It's polyhedron, not polygon
Because above figure has merely 10 sides.
so the polyhedron above has 10 sides, each of them has 20°.
so total degree in polyhedron is > 180(n-2)
>180(10-2)
> 180×8
> 1440

Answer:
P'(7,0)Q'(2,1) R'(12,-6)
Step-by-step explanation:
P(3,5)------>P'(3+4,5-5)
P'(7,0)
Q(-2,6)----->Q'(-2+4,6-5)
Q'(2,1)
R(8,-1)------>R'(8+4,-1-5)
R'(12,-6)
