Answer:
7.67
Step-by-step explanation:
Given the data :
Week_sales_Forecast ___|error|_ |error|²
1 _____15
2 ____ 16
3 ____ 19
4 ____ 18
5 ____ 19 ____ 17 _______ 2____4
6 ____ 20 ___ 18 ________2____4
7 ____ 19 ____19 ________0____0
8 ___ 22 ____ 19 ________3____9
9 ___ 15 ____ 20 ________5___ 25
10 __ 21 _____19 ________ 2 ___ 4
Mean squared error :
(4 + 4 + 0 + 9 + 25 + 4) / 6
= 46 / 6
= 7.666
= 7.67
I believe is C because the formula is
Y = mx + b
Since your m value is -6/5 and your x value is -3, and y value is -7
Then your answer would be
Y - 7 = -6/5 (x - 3)
We will determine the surface area as follows:

So, the total surface area is 150 cm^2.
Answer:
The value of w is 7.
Step-by-step explanation:
According to Pythagoras theorem,
Hypotenuse²=Perpendicular²+Base²
H²=P²+B²
Here,
Hypotenuse given=7√2
w=y
Perpendicular=Base=x
(7√2)²=x²+x²
49*2=2x²
(49*2)/2=x²
49=x²
√49=x
7=x
Perpendicular=x=7
Let... the smaller integer be x
Then, the larger integer is 2x+26(Two times.. =2x, 26 more... is =2x+26
Both added is 74
2x+26=74
2x=74−26
2x=48
x=24
