The quadratic regression graphed on the coordinate grid represents the height of a road surface x meters from the center of the

road.
A graph shows the horizontal axis numbered negative 7 to positive 7 and the vertical axis numbered negative 1.25 to positive 1.25. A line shows an upward then downward trend.
What does the graph of the regression model show?

The height of the surface decreases from the center out to the sides of the road.
The height of the surface increases, then decreases, from the center out to the sides of the road.
The height of the surface increases from the center out to the sides of the road.
The height of the surface remains the same the entire distance across the road.

The height of the surface increases, then decreases, from the center out to the sides of the road.

<h3>What is quadratic equation?</h3>

The polynomial having a degree of 2 is defined as the quadratic equation it means that the variable will have a maximum power of 2.

Let

y------> the height of the surface

x------> the road

we know that

The quadratic regression graphed represent a vertical parabola open downward

The function increase in the interval --------> (-5,0)        

The function decrease in the interval -------->   (0,5)

therefore

The height of the surface increases, then decreases, from the center out to the sides of the road.

Contact [7]

Answer:

MAYA (6 minutes)

Amy (7 minutes)

Step-by-step explanation:

MAYA

Takes Maya 30 minutes to solve 5 Puzzle:

Let's express it as,

30 mins = 5 Puzzle

1 min = x Puzzle

Cross multiply to solve for the number of questions Maya solves in a minute.

It becomes:

30*x = 5*1

30x = 5

x = 30/5

x = 6mins.

It means it takes Maya 6 mins to solve one question.

FOR AMY

Takes Amy 28 mins to solve 4 puzzles.

Let's represent it as:

28 mins = 4 Puzzles

x min = 1 puzzle

Let's solve for x

(28 mins) * (1 puzzle) = 4 * x

28 = 4x

x = 28/4

x = 7 mins

It means, it takes Amy 7 minutes to solve 1 puzzle

Suppose the test scores of students in a class are normally distributed with a mean of 86 and a standard deviation of 4. What is
WARRIOR [948]

Answer:

-2.5

Step-by-step explanation:

Here in this question, we are interested in calculating the z-score for a student that had a particular mark at the test

To calculate the z-score, we need to use a mathematical formula

Mathematically;

z-score = (x - mean)/SD

From the question;

x = 76

mean = 86

standard deviation SD = 4

Plugging these values in the equation, we have;

z-score = (76-86)/4 = -10/4 = -2.5

Ede4ka [16]

Solution:

we are given that

A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the schoo. The order of selection does not matter.

As we know

6 teacheras can be selected out of 30 teacher in {30}_C_6 ways.

{30}_C_6=\frac{30!}{6!24!}\\&#10;\\  {30}_C_6=\frac{25*26*27*28*29*30}{1*2*3*4*5*6}\\&#10;\\  {30}_C_6=593775

Hence the required number of ways is 593775.

The scale on a map is 2cm= 1km. Express this as a ratio
Lemur [1.5K]
This would mean that the ratio is 2:1 or 2 to 1 or also 2/1.

The ratio would be that because it's 2 centimeters per 1 kilometer.
