Answer:
The predicted value of the year 18 is 107
Step-by-step explanation:
create a scatter plot for year and mean variables.
(<em>i have done that with Microsoft excel check the attachment from 1-3)</em>
Least square regression equation:
y = 9.3187x - 61.121
Predicted value of the lean 18
y = 9.3187 x (18) - 61.121
y = 107
The predicted value of the year 18 is 107
Answer:
Step-by-step explanation:
Given
-43 to the left of -35
Required
Represent as inequality
-43 to the left of -35 implies that -43 is less than 35.
In inequality, less than <
So:
The answer of this question is b and e
Answer:
Step-by-step explanation:
l = 5 in
w = 5 in
h = 12 in
Surface area of rectangular prism = 2*(lw +wh + hl)
= 2*(5*5 + 5*12 + 12*5)
= 2*(25 +60 +60)
= 2*145
= 290 in²
Answer: 15) 97
16) 16
17) 24
Step-by-step explanation:
15) (x-75) + (x-52)+ 293=360
x - 75 + x - 52 + 293 = 360
2x - 127 + 293 = 360
2x + 166 = 360
2x = 194 [Subtract 166 from both side]
x = 97 [Divide by 2 from both side]
16) (4x+15)+(5+6x)=180 The angle of a straight line is 180.
4x + 15 + 5 + 6x = 180
10x + 20 = 180
10x = 160 [Subtract 20 from both side]
x = 16 [Divide by 10 from both side]
17) (x+17)+(2x+1)= 90 These two angle combined equal to 90.
x + 17 + 2x + 1 = 90
3x + 18 = 90
3x = 72 [Subtract 18 from both side]
x = 24 [Divide by 3 from both side]
