Answer: 62.5%

Step-by-step explanation:

5/8 = 0.625

0.625 x 100 = 62.5

Step-by-step explanation:

the angle CDB is the supplementary angle to 9x+10 (angle ADC).

that means they stand together for 180°. as all angles around a single point on one side of a line are together always 180°.

and then, the sum of all angles in a triangle is always 180°.

so,

CDB + (4x + 10) + 50 = 180

CDB = 180 - (9x + 10) = 180 - 9x - 19 = 170 - 9x

therefore,

(170 - 9x) + (4x + 10) + 50 = 180

170 - 9x + 4x + 10 + 50 = 180

-5x = -50

5x = 50

x = 10

angle CDB = 170 - 9x = 170 - 90 = 80°

There was a missing data point in the Homework Grade.  So I put a 74 to get 8 data points on each variable.

Put these data points in Excel.  In the Data Analysis tab, scroll down and click on Regression.  Input Y range for Test Grade and Input X range for Homework Grade.

y = -0.4x + 98.3

correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data.

When you increase your homework score by 1 point, you lose 0.4 points on your test.

-0.4x + 98.3 = 74

→  -0.4x = -24.3  

→  x = 60.75 ≈ 61

A student will earn a 61 on his/her homework if he/she earns a 74 on an exam.

Answer:

1.64

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6.6^2 + x^2 = 6.8^2

43.56+x^2=46.24

Subtract 43.56 from each side

x^2 = 46.24-43.56

x^2 =2.68

Take the square root of each side

sqrt(x^2) = sqrt(2.68)

x =1.637080554

To 3 significant digits

x = 1.64

Answer:

Step-by-step explanation:

       x = 1.637 mm

        We can use Pythagorean theorem, to find the unknown side for a right angled triangle.

The side opposite to 90 is the longest side and it is the hypotenuse.

Base² + altitude² = hypotenuse²

 x²     + 6.6²        = 6.8²

      x²  +  43.56  = 46.24

                     x²   = 46.24 - 43.56

                    x²    = 2.68

                      x   = √2.68

The length of side of triangle portion CE is 16.

When two triangles forms on the same base, has its other two sides in proportional with each other, the triangles are known as the similar triangles.

Given, the dimensions AD = 24, DB = 27 and EB = 18.

In the given diagram of two similar triangles, ABC and DBE

DB/AD = EB/CE

Substitute the values, we get

27/24 = 18/CE

CE= 16

Thus, the value of CE = 16

Step-by-step explanation:

[tex]\sin 40^{\circ}=\frac{x}{45} \\ \\ x=45 \sin 40^{\circ} \approx 28.925[/tex]

The height of point P above the level of point Q is given by trigonometric relations h = 34.7 km

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let's call the height of point P above the level of point Q as h.

We know that the angle of elevation of point P from point Q is 40°, which means that the angle between the horizontal line passing through Q and the line segment connecting Q and P is 40°.

We also know that PQ = 45 km, which represents the distance between Q and P.

Using trigonometry, we can set up the following equation:

tan(40°) = h / 45

Solving for h, we get:

h = 45 x tan(40°) ≈ 34.7 km

Therefore, point P is approximately 34.7 km above the level of point Q

Hence , the height is h = 34.7 km
