What is quadratic regression?The quadratic regression is the statistical process which is used to obtain the equation of parabola, to represent the data set in the most appropriate way.
The things which are necessary to know in order to solve problems involving quadratic regression are listed below.
The most important thing for approaching quadratic regression problem is visualize the data.Make a proper table with x and y values with the data. These values should form a parabola for the quadratic regression.Find the correlation coefficient. The closer the value of correlation coefficient to 1, the data good fit into the quadratic equation.Least square method is the best way to solve the problems involving quadratic regression.Thus, the things which are necessary to know in order to solve problems involving quadratic regression are data, correlation coefficient and quadratic equation.

The graph of a line and and exponential intersect twice, once, or not at all. Describe the possible number of intersections of each of the following pairs of graph. Your solution to each part should include all of the possibilities and a quickly sketched example of each one. (Part 1)(SHOW WORK)
a. A line and a parabola
b. Two different parabolas
Answers
a) A line can intersect a parabola at 2 points, 1 point, or no points respectively. The only possible way at which it intersects at 1 point, would be if it were tangent to the parabola. [Check first attachment]
b) Two different parabolas can intersect at 2 points, 1 point or no points respectively. [Check second attachment]
It is possible for 2 parabolas to intersect at 4 and even 3 points. But one of the parabolas would be on it's side. You can consider those cases.

answers / step-by-step explanation:
every single one of these equations false
3² = 2 * 2 * 2
is false since three multiplied by itself equals to 9 and 2 multiplied by itself 3 times equals to 8 and as you can see, they are not the same numbers
9 > 8
5^(3)=15
is also false since 5^(3) equals to 125 and 15 do not equal to each other since they are not the same number
125 > 15
8^(1 )=7^(1)
is the easiest one because it is basically just asking if 8 = 7 and to answer that question, it doesn't
8 > 7

Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 kilometres per hour and the other travels at an average speed of 70 kilometres per hour. How long after they leave the station will they be 50 km apart?
Answers
9514 1404 393
Answer:
20 minutes
Step-by-step explanation:
The trains are separating at the rate of 80 +70 = 150 km/hour. The time required to be 50 km apart is then ...
time = distance/speed = (50 km)/(150 km/h) = 1/3 h = 20 minutes
If 70% of a number is 42 and 15% of the same number is 9, find 85% of that number.
Answers
Answer: 51
Step-by-step explanation:
let x be the number.
(70%)x = 42
0.7 x = 42
x = 60
we check 15% x 60 = 0.15 x 60 = 9, which is true.
85% of that number = 85% x 60 = 0.85 x 60 = 51.

Step-by-step explanation:
The angles of a triangle are (x - 5), (x + 15)°
and (2x + 10). Given that the sum of the
angles of a triangle is 180°, calculate the size
of each angle.
Answers
Answer:
35°, 55°, 90°
Step-by-step explanation:
Since all the angles of a triangle equal 180, add them all together and set them equal to 180.
(x-5)+(x+15)+(2x+10)=180
Now solve for each angle.
(40-5)
=35°
(40+15)
=55°
(2(40)+10)
=90°
Now check your work.
35°+55°+90°
=180°

Answers
9514 1404 393
Answer:
n = 4
Step-by-step explanation:
Of the 40 people, half are women, so there are 20 women.
There are 5 times as many women as men, so 20/5 = 4 are men.
The remainder are children, so there are 20-4 = 16 children.
The ratio of children to men is ...
children : men = 16 : 4 = 4 : 1 = n : 1 . . . . . . . . remove a factor of 4 from 16:4
The value of n is 4.
