O y= 1.04x - 2.29
O y = 2.29x -1.04
O y = 0.28x -0.77
O y = 77x + 28

Answers

Answer 1

Answer:

y = 0.28X - 0.77

Step-by-step explanation:

Given the data :

у:

Equation of regression line is in the form:

y = mx + c

Where y = predicted variable ;

c = intercept ; m = slope or gradient ; x = predictor variable

Using The correlation Coefficient calculator :

The regression equation obtained is :

ŷ = 0.2754X - 0.77028

Rounding values in our regression output to 2 decimal places :

y = 0.28X - 0.77

Hence best model to make prediction :

y = 0.28X - 0.77

what is the distance between points (9,-7) and (9,4) on a coordinate plane

Answers

Answer:

Step-by-step explanation:

The distance formula is d=√x2 - x1²+ y2 - y1².

The first thing to do is substitute the numbers we have into this formula.

d=√9 - 9²+ 4 - -7²

d=√0² + 11²

d = d=√0 + 121

d = d=√121

d = 11

The correct answer is option A.
Pumpkin seeds have more protein because 58.5 grams of protein divided by 6.5 ounces equals 9 grams of protein per ounce. Now, the sunflower seeds have less protein because 96 grams of protein divided by 16 ounces per pound is 6 grams of protein per ounce. To find the difference in the grams per 24 ounces, take 9 grams of protein per one ounce of pumpkin seeds and multiply it by 24 to get 216 grams per 24 ounces. 6 grams per 1 ounce of sunflower seed times 24 ounces equals 144 grams of protein per 24 ounces. So, 216 grams of protein per 24 ounces of pumpkin seeds minus 144 grams of protein per 24 of sunflower seeds, equals 72 grams, therefore there is 72 more grams of protein per 24 ounces of pumpkin seeds.

[tex]-\frac{3}{2}[/tex]

Step-by-step explanation:

To find the slope of the given line, slope is the rise divided by the run of a line.

Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Picking points (4, 18) and (8, 12)

Now;

x₁ = 4

y₁ = 18

x₂ = 8

y₂ = 12

Slope = [tex]\frac{12 - 18}{8-4}[/tex] = [tex]-\frac{6}{4}[/tex] = [tex]-\frac{3}{2}[/tex]

What is the solution to this system of equations?
3x + y = 17
x + 2y = 49

A. It has no solution.

B. It has infinite solutions.

C. It has a single solution: x = 15, y = 17.

D. It has a single solution: x = -3, y = 26.

Answers

The answer is D,
Multiply the first equation by 2 and you get 6x+2y=34, you can then subtract the second equation from this and you gey 5x=-15, so x is -3, you can substitute this value of x into any of the 2 equations and find the value of y

can someone find the measures of angle 1 & 2?

Answers

Answer:

angle 1 equals 55 and angle 2= equals 115

Step-by-step explanation:

the middle angle is 125 so than you add 63+__ which is 62 so than the last angle to make 180 is 55(angle 1) than angle 2 10+__=125 so ___=115 than the last angle will be 55

Answer:

1) 62°

2) 115°

Step-by-step explanation:

Angle 1)

QRP= 180°-125° (adjacent angles on a straight line)

= 55°

angle 1= 180°-63°-55° (sum of angles in a triangle)

= 62°

Angle 2)

SRT= QRP (vertically opposite angles)

= 55°

angle 2= 180°-10°-55° (sum of angles in a triangle)

= 115°

A sporting goods store sells shirts for $20 each. If the store offers a 40% discount, what will be the selling price of each shirt? $12, $8, $28, or $16

Answers

Answer:

The selling price for each shirt would be 8 dollars.

Step-by-step explanation:

10% of $20 is 2 and to make a whole would be 10% x 10 = 100%

so 2 x 10 = 20

we could break this down to 2+2+2+2+2+2+2+2+2+2=20

we know that one 2 is 10% so to make 40% we need 4.

parabola have?

Answers

Answer:

2 solutions

Step-by-step explanation:

Given the graph of a parabola , then the solutions are the values of x on the x- axis where the graph crosses the x- axis.

The graph crosses the x- axis at x = - 2 and x = 2

Thus there are 2 solutions

The parabola has two solutions or roots.

In general, a quadratic equation represented by a parabola can have zero, one, or two solutions. The number of solutions depends on the discriminant of the quadratic equation. If the discriminant is positive, the quadratic equation has two distinct solutions. If the discriminant is zero, it has one solution (a double root). If the discriminant is negative, it has no real solutions.

In this case the graph of a parabola cuts the x-axis two times, it means that the parabola has two x-intercepts or solutions. In other words, the equation representing the parabola will have two distinct real solutions. The x-intercepts are the points where the parabola intersects the x-axis, and they correspond to the values of x for which the y-coordinate is zero.

Therefore, in this case, the parabola has two solutions or roots.
