plz help math question

Answers

Answer:

y = -2x +20

6x - 5y = 12

Put the value of y in 2nd equation

6x - 5( -2x +20 ) = 12

6x +10x -40 = 12

16x = 12 +40

16x = 52

x = 13/4

Putting the value of x in equation 1

y = -2x +20

y = -2(13/4 ) +20

y = 27/2

Answer:

x = 9

Step-by-step explanation:

(3x-20)/9 = 56/72

72(3x-20) = 9(56)

216x-1440 = 504

add 1440 to each side

216x = 1944

divide both sides by 216

x = 9

Answer:

9

Step-by-step explanation:

If you draw a segment parallel to a side of triangle that intersects two sides of the triangle, that segment divides the intersected sides into segments of proportional lengths.

9/72 = (3x - 20)/56

1/8 = (3x - 20)/56

3x - 20 = 1/8 * 56

3x - 20 = 7

3x = 27

x = 9

Annual snowfall in Anchorage, Alaska, is normally distributed with a mean height of 76 inches and a standard deviation of 4.7 inches. What is the probability this year that it will snow between 71.4 and 80.7 inches in Anchorage?​

Answers

Using the Empirical Rule, it is found that there is a 68% probability this year that it will snow between 71.4 and 80.7 inches in Anchorage.

What is the Empirical Rule?

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of  the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, the mean height of 76 inches and a standard deviation of 4.7 inches, hence 71.4 and 80.7 inches is within 1 standard deviation of the mean, that is, there is a 68% probability this year that it will snow between 71.4 and 80.7 inches in Anchorage.

Answers

Answer:

angle B = 127.5 degrees

angle D = 127.5 degrees

Step-by-step explanation:

The above figure is of a kite.

the non-vertex angles( I. e angle B and angle D) are congruent to each other in a kite.

Let angle B be x.

therefore, angle D is also x. ......(as they are congruent to each other)

The sum of all the angles in a quadrilateral is 360 degrees.

therefore,

65 + 40 + x + x = 360

105 + 2x = 360

2x = 360 - 105

2x = 255

x = 255/2

x = 127.5

therefore, angle B and Angle D are 127.5 degrees each.

3. Find the measure of the sides of the triangle if the vertices of AEFG are E
(1,4), F(5, 4), and G(1,0). Then classify the triangle by its sides.

Answers

The triangle EFG is an isosceles triangle as side EF is congruent to side EG.

How to determine a triangle according to its sides

In this question we have a triangle whose vertices are known. We need to define the figure according to the congruency among its sides. Two sides are congruent when both have the same length. There are three kinds of triangles:

Scalene - Three sides of different length.Isosceles - Two sides of equal length.Equilateral - All sides are of equal length.

Sides are formed each pair of vertices. The length of each side can be found by means of Pythagorean theorem:

l = √[(Δx)² + (Δy)²]

First, write the locations of the vertices:

E(x, y) = (1, 4), F(x, y) = (5, 4), G(x, y) = (1, 0)

Second, determine the length of every side of the triangle:

EF = √[(5 - 1)² + (4 - 4)²]

EF = 4

FG = √[(1 - 5)² + (0 - 4)²]

FG = √[4² + (- 4)²]

FG = 4√2

EG = √[(1 - 1)² + (0 - 4)²]

EG = 4

By direct comparison, we conclude that the triangle EFG is an isosceles triangle.
