10. 24x-8. 11. 5x+6x+2x+15x=28x I hope this is right
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Equation of regression line :
Yˆ = −114.05+2.17X
X = Temperature in degrees Fahrenheit (°F)
Y = Number of bags of ice sold
On one of the observed days, the temperature was 82 °F and 66 bags of ice were sold.
X = 82°F ; Y = 66 bags of ice sold
1. Determine the number of bags of ice predicted to be sold by the LSR line, Yˆ, when the temperature is 82 °F.
X = 82°F
Yˆ = −114.05+2.17(82)
Y = - 114.05 + 177.94
Y = 63.89
Y = 64 bags
2. Compute the residual at this temperature.
Residual = Actual value - predicted value
Residual = 66 - 64 = 2 bags of ice
Answer: the total of the tip is 2 dollars
it also depends for how many people
Step-by-step explanation:
10
Therefore, the greatest common factor of 30 and 50 is 10.
Answer:
32
Step-by-step explanation:
16/20 reduces down to 2/5
set 2/5=x/80
cross multiply 160=5x
divide 32=x
check 2/5=32/80
32/80; 16/40; 8/20; 4/10; 2/5
yay 32 is the answer good luck :)
