Answer:
$64
Step-by-step explanation:
3 1/2 = (2×3 + 1)/2 = 7/2 = 3.5
3.5 ounces ..................... $224
1 ounce .............................$ x
x = 224×1/3.5 = $64
Answer:
The regression equation for the sample is
Y= 0.430x +0.214
Step-by-step explanation:
Using the regression formula;
a= (nSSXY - MX MY)/(nSSX -MX^2)
a= (20×43- 4×6)/(20×98 - (4^2))
a= 836/(1960-16)
a= 836/1944
a= 0.430
X bar= summation x / n =4/20= 0.2
Y bar= summation y / n =6/20 = 0.3
b= y bar - a xbar
b= 0.3 - 0.430(0.2)
b= 0.3- 0.086
b= 0.214
The regression equation
Y= ax + b
Y= 0.430x +0.214
Convert the fraction to a decimal by dividing the numerator by the denominator to approximate the decimal result.

Answer:
-2 > -6 . . . or . . . R > S
Step-by-step explanation:
If you plot the temperatures of the two cities on a number line, you see that the temperature for City R is plotted to the right of the temperature for City S. This means the temperature of City S is less than that of City R.
If your inequality relates cities:
S < R or R > S
If your inequality relates temperatures:
-6 < -2 or -2 > -6
