The parallel street to that one lines on the equation y = 2x -1

To find the parallel street to the one we have the points given, we have to first of all, find the slope of the given point and then pick a coordinate.

Using the value above, let's find the slope of the line.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1} \\[/tex]

Let's substitute the values into the equation and solve.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1} \\\\m = \frac{9 - (-5)}{5 - (-2)} \\m = \frac{14}{7} \\m = 2[/tex]

The slope of the line is equal to 2.

Let's use this to find the equation of the line

[tex]y = mx + c[/tex]

Using one of the points,

[tex]y = mx + c\\9 = 2(5) + c\\9 = 10 + c\\c = - 1\\[/tex]

The equation of the line is

[tex]y = 2x - 1[/tex]

From the calculation above, the equation of the line is y = 2x - 1

The likelihood or probability that she will give the first student a blue calculator and the second student a yellow calculator is 6.6%.

The math teacher Mrs. Piatt has six black, nine yellow, and two blue calculators.

Therefore, the total number of calculators is 17.

The probability that she hands out a blue calculator to the first student is:

P₁ = Number of blue calculators/ Total number of calculator

P₁ = 2/17

Now, as a calculator is handed out to a student. Then the remaining number of calculators is 16.

Therefore, the probability that the second student gets a yellow calculator will:

P₂ = Number of yellow calculators/ Total number of calculators.

P₂ = 9/16

Therefore, the probability that she will hand out a blue calculator to the first student, then hand out a yellow calculator second will be:

P = P₁ × P₂

P = 2/17 × 9/16

P = 18/272

P = 0.06617647058

The smallest possible number of students in the algebra class is 13.

Let n≥5 be the number of students.

The sum of their scores must be at least 5×100 + (n - 5).

Simultaneously, we must achieve the mean 76, which is equivalent to achieving the mean sum 76n.

As a result, we have a sufficient precondition on n: we should have 5×100 + (n - 5) ≤ 76n.

This can be reduced to 200 ≤ 16n. This is true for the smallest integer n = 13.

To complete our solution, we must now determine how 13 students might have scored just on test.

We have 13×76 = 988 points to distribute to them. Because five 100s equal 500, we must distribute the remaining 488 points as among remaining eight students.

This can be accomplished, for example, by awarding each of them 61 points.

Thus, the smallest possible number of students in the class is 13.

Answer:

k = 1

Step-by-step explanation:

since the graph contains the point (2, 12 ) then the coordinates of the point make the equation true.

substitute x = 2 and f(x) = 12 into the equation and solve for k

12 = k(2)³ + 2² - k(2) + 2 , that is

12 = 8k + 4 - 2k + 2

12 = 6k + 6 ( subtract 6 from both sides )

6 = 6k ( divide both sides by 6 )

1 = k

The coordinates of the image of polygon A'B'C'D' after a translation of 4 units down and 5 units right would be A' (-1, 1), B' (-1, -2), C' (3, -2), D' (3, 2).

In Geometry, the translation of a geometric figure to the right simply means subtracting a digit from the value on the x-coordinate (x-axis) of the pre-image and translating a geometric figure down simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.

By translating the pre-image of polygon ABCD vertically down 4 units and horizontally right 5 units, the coordinates of the image of polygon A'B'C'D' include the following:

(x, y)                               →                  (x + 5, y - 4)

Coordinate A = (-6, 5)   →    Coordinate A' (-6 + 5, 5 - 4) = (-1, 1)

Coordinate B = (-6, 2)   →    Coordinate B' = (-6 + 5, 2 - 4) = (-1, -2)

Coordinate C = (-2, 2)   →     Coordinate C' = (-2 + 5, 2 - 4) = (3, -2)

A kite contains four inner angles, which add up to 360 degrees. It has one pair of equal and opposite obtuse angles in each of these angles.

Answer:

∠D = 94°

Step-by-step explanation:

A kite is a quadrilateral.  

Therefore, the sum of its interior angles is 360°.

⇒ ∠A + ∠B + ∠C + ∠D = 360°

⇒ 108° + ∠B + 64° + ∠D = 360°

⇒ 172° + ∠B + ∠D = 360°

⇒ ∠B + ∠D = 188°

A kite has one pair of opposite (obtuse) angles that are equal.

Therefore, ∠D = ∠B.

⇒ ∠B + ∠D = 188°

⇒ ∠D + ∠D = 188°

⇒ 2∠D = 188°

⇒ ∠D = 94°

The distance between each infant's weight when they were bonded in April is the proper interpretation of the standard deviation in this situation. And the average weight was 10.20 pounds.

The variance's positive square root is the standard deviation. One of the foundational strategies in statistical analysis is standard deviation. The term "standard deviation," often shortened as "SD," tells us how far a value deviates from the mean value. It is represented by the symbol "."

Given that : The mean birth weights of infants born at an area hospital in the month of April is 128 oz. with a standard deviation of 10.2 oz.

So let's look at this and see what the correct interpretation of a standard deviation is, which is the distance between each person's actual way of being born and a braille and the main way it was, which is typically about 10 points two oh. From this, we can deduce what the question Act is. The distance between each infant's weight when they were bonded in April is the proper interpretation of the standard deviation in this situation.
