Answer:
B.The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%.
Step-by-step explanation:
A regression equation is it this form:
Y' = b0 + b1X
I am going to identify the slope and intercept in this equation to help us go further in our solution.
b1X is the slope. The slope usually has an x value multiplied to it
b0 is the intercept.
Back to our question, the equation in this question is
Y = -0.42X + 19.26
The slope is -0.42X.
The y intercept is 19.26
<em><u>The slope has a negative sign, this shows us that the percentage is falling by about 0.4% every year while an intercept of 19.26 tells us that percentage in 1985 should have been about 19%.</u></em>
I hope you found my solution useful?
Hello,
f(1)=2-9+12-12+10-3=0 ===>(x-1)*....
f(3)=2*3^5-9*3^4+12*3^3-12*3^2+10*3-3=0 ===> (x-3)*....
f(1/2)=2*(1/2)^5-9*(1/2)^4+12*(1/2)^3-12*(1/2)^2+10*1/2-3=0 ===>(2x-1)*...
f(x)=(x-1)(x-3)*(2x-1)*(x²+1)
In C, x=i ou x=-i
Zeros are 1/2,1,3,i,-i
It would be b because the circumference equals the diameter times pi. You can remember this with the saying cherry pie delicious (c=pi x d)
Answer:
x + 90 = 120
Step-by-step explanation:
the marked angles are vertically opposite angles and are congruent , then
4x = x + 90 ( subtract x from both sides )
3x = 90 ( divide both sides by 3 )
x = 30
then
x + 90 = 30 + 90 = 120
