Ok so the answer in here is <span>60 grams of the alloy with 10% of titanium needed and 40 grams of the alloy with 25% of titanium are needed.
Let me explain it to you
</span>let x = grams of alloy A and y = grams of alloy B.
x + y = 100
which is
mass of A + mass of B = 100
and
0.15x + 0.20y = 0.17*100
which is
fractionA*massA + fractionB*massB = fractionTotal*massTotal
<span>0.15(100 - y) + 0.20y = 17
15 - 0.15y + 0.20y = 17
0.05y = 2
y = 40 grams
x = 100 - y = 60 grams</span>
Answer:
y = 3.5X - 6921.2
Step-by-step explanation:
Given the data :
X :
1990
1992
1994
1996
1996
Y :
45
51
57
61
75
Using an online regression calculator ; the regression model obtained is : y = 3.5X - 6921.2
Where ; slope = 3.5 ; intercept = - 6921.2
Answer:
The equation of Line is y = - 8x + 7
Step-by-step explanation:
Given as :
The slop of line is - 8
And The y intercept is 7
As the equation of line is y = mx + c
For y intercept , x = 0
So, With y intercept and slop ,
7 = (-8)× (0)+ c
Or, c = 7
So the equation of line is
y = mx + c
I.e y = ( - 8 ) x + 7
Hence The equation of Line is y = - 8x + 7 Answer
