Answer:
a=200;110;101andb=decreasing
Step-by-step explanation:
a.(100×10+1000)/10=200
(100×100+1000)/100=110
(100×1000+1000)/1000=101
There is eight ounces in one cup. And she needs 4 cups of water. Eight times 4 equals 32. She needs 32 ounces of water
Answer:
<em>Predicted height: 57.42 inches</em>
<em>Residual: 2.58 inches</em>
Step-by-step explanation:
<u>Regression Equation</u>
The regression equation for the height of the children (Hgt) and their age (Age) is given by the expression
Hgt = 24.3 + 2.76(Age)
We must compare the predicted value of the equation vs the real data point Age=12, Height=60
Computing the predicted height
Hgt = 24.3 + 2.76(12)
Hgt=57.42 inches
The residual is the difference between the real data point and the predicted value
R=60-57.42
R=2.58 inches
Step-by-step explanation:
multiplying the 2nd eqn by 9 we get,
9x+9y=81
then,subtracting 1st and 2nd eqn
9x+5y=41
9x+9y=81
- - -
__________
0. -4y=-40
we get y = 10
then we get x=9-y
x=9-10
x= -1
so x is -1 and y is 10
Answer:
New line =3*ZX
Step-by-step explanation:
It is given that the isosceles trapezoid is dilated using a scale factor of 1/3
and a line is drawn through the center of the new dilated figure, so
let us suppose that line is EF which is drawn and it will also pass through
the center in similar way the line ZX passes through so after considering this situation, we can come to this point

so new line will be 3 times longer than ZX.
