The quadratic regression equation that models these data is y = –0.34x2 + 4.43x + 3.46. using the quadratic regression equation, what was the predicted profit in year 10?

13.76

Step-by-step explanation:

We want year 10; this means we substitute 10 in place of x:

y=-0.34(10²)+4.43(10)+3.46

y = -0.34(100)+4.43(10)+3.46

y = -34+44.3+3.46 = 13.76

Profit in year 10 is 13.76 million dollars.

Step-by-step explanation:

The quadratic regression equation that models the data is y = -0.34x² + 4.43x + 3.46

Here "y" defines the profit in the year and x is the number of years.

We have to calculate the predicted profit in year 10.

We can get the predicted profit from the regression equation by putting the value x= 10.

y = -0.34×(10)² + 4.43(10) + 3.46

  = -34 + 44.3 + 3.46

  = 13.76

Therefore profit generated will be 13.76 million dollars.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
