c) x = 20, angle COD = 70 °

Step-by-step explanation:

(x+50)° + 90° +20° = 180°

x + 160° = 180°

x = 180°- 160°

x = 20

Angle COD = (x+50)° = (20 +50)° = 70°

11. Write down three different whole numbers so that: • the median of the three numbers is 13, the range of the three numbers is 5.

Answers

Step-by-step explanation:

Let the numbers be a, b, c in ascending order.

Mean is 7, i.e. (a+b+c)/3 = 7 or a+b+c=21

Median(middle number) is 5, i.e. b=5

Range is 8, i.e. c-a=8 or c=8+a

Solving the above three equations simultaneously, we have

a+5+8+a=21

a=4, hence c=12

Therefore the three numbers are 4, 5 and 12

What is 18.5% of 500?

0.925

Answers

Answer:

92.5

Step-by-step explanation:

[tex]\frac{18.5}{100} = \frac{x}{500}[/tex]

cross multiply:

18.5 · 500 = 9250

100 · x = 100x

isolate x by dividing 100 from both sides:

x = 92.5

hope this helps!

18.5% × 500 = 92.5

The equation of the trend line is ŷ = 0.15x - 23.21

How to determine the average rate of change of the trend line?

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956Sum of Y = 680Mean X = 661.7778Mean Y = 75.5556Sum of squares (SSX) = 50569.5556Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21

Answer:

Step-by-step explanation:

They are all solved kind of the same way. If the vertex of the angle is outside of the circle, subtract the intercepted arcs and divide by 2

for 15) one arc is marked but you can figure out the other arc because there are 360 degrees in a circle 360 - 102 = 258. So the two arcs are 102 degrees and 258 degrees.

some of the problems you can set up the equation and solve.

17) 63 = {(360-x) - x} /2 multiply by 2

126 = {(360-x) - x} combine like terms

126 = 360 - 2x subtract 360

-234 = -2x divide by -2

117 = x

? = 117 degrees

Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers use regression models to predict the height of a tree from its diameter measured at 4 feet 6 inches from the ground. The following computer output shows the results of a linear regression based on the heights, in feet, and the diameters, in inches, recorded from 31 felled trees.

Answers

Measuring the height of a tree is usually more difficult than measuring the diameter of the tree, confidence interval for the slope is mathematically given as

C=(0.396, 1.712)

What is a 95 percent confidence interval for the slope of the population regression line?

Generally, the equation for the confidence interval is mathematically given as

[tex]C=\beta-tn-2, \alpha /2 (S.E)[/tex]

Where

[tex]\beta=1.054[/tex]

Therefore

C=(1.054-t29, 0.025*0.322)

C=(0.396, 1.712)

In conclusion, the 95 percent confidence interval is

C=(0.396, 1.712)

A shopkeeper bought 30 pens for 150 and sold 20 of them for 140. Find his profit or loss percentage

Answers

Answer:

Because the cost price of 30 pens = Rs. 150

So, the cost price of 1 pen = 150/30 =5

so, the cost price of 20 pens =

Rs. 5 x 20 = 100

Cp is Rs. 100

Sp is Rs. 140

So, profit = 140-100 = Rs. 40

Profit % = (Profit x 100)xCp

=(40 x 100)/100

= 4000/100

= 40% profit

Answer:

4th option

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

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

with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line

m = [tex]\frac{6-12}{6-2}[/tex] = [tex]\frac{-6}{4}[/tex] = - [tex]\frac{3}{2}[/tex]
