What type of sample produces valid results?

A. Biased
B. Convenience
C. Voluntary Response
D. Systematic Random

Trigonometric Functions -

[tex] \cos = \frac{adjacent}{hypotenuse} [/tex]

Find the opposite side, first of all.

Pythagorean Theorem -

[tex]a^{2} + b^{2} = c^{2} [/tex]

Input the hypotenuse and opposite sides to find b^2.

[tex]49 + {b}^{2} = 64[/tex]

Minus 49 from equations to get b^2 by itself.

[tex] {b}^{2} = 15[/tex]

Square root b^2 and 15 to get b by itself.

[tex]b = \sqrt{15} [/tex]

Now we can get to the trigonometry functioms!

[tex] \frac{ \sqrt{15} }{8} [/tex]

Divide them up, then find the percentage!

48% or...

[tex] \frac{ \sqrt{15} }{8} [/tex]

Answer:

(4p^2+3)(p+2)

Step-by-step explanation:

The twο different quantities tο measure which school has higher academic performance are :

• Graduation rate / Budget per student

• SAT average / Budget per student

In οther to define a quantity which measures academic achievement;

We take the ratio of a related metric οr parameter which is a measure of the academic perfοrmance of the student in each school and the budget per student for each schοol .

The parameters which cοuld be used to measure academic achievement are :

• The graduation rate οf each school.

• The SAT average of each schοol.

Hence, defining the quantity tο measure academic achievement relative to budget per student cοuld be expressed as :

• Graduation rate / Budget per student

• SAT average / Budget per student

Answer: (b) -7/2, 6.

Step-by-step Explanation: We put x = 0; then y = 6; y-intercept of the line is (0,6).

For the slope: 4y = 24 - 14x; then, y = (-7/2)x + 6; the slope is -7/2.

Answer:  The answer would be letter B. -7/2; 6

Use the slope-intercept form  y =  m x  +  b to find the slope  m  and y-intercept  b .

Slope:  

− 7 /2

y-intercept:  

( 0 ,  6)

Step-by-step explanation:  You have to find the slope and y-intercept

Find the slope and y-intercept of the line.

14x + 4y = 24

Find the Slope and y-intercept

Answer:

62,118

Step-by-step explanation:

Let one angle = x

So, other angle = x +56

x +x +56 = 180       {Combine like terms}

2x  + 5 6 = 180      {Subtract 56 form both sides}

        2x = 180 - 56

        2x = 124     {Divide both sides by 2}

        x   = 124/2

        x = 62

Other angle = 62 + 56  = 118

Answer: Fur tree = 6 meters, pine tree = 15 meters

Step-by-step explanation:

Lets say the height of one fur tree is x

the height of one pine tree is y

so x+y=21 and 4x=24

x = 6

y = 15

Answer:

12% of 7.99

=0.96$

so...

The cost after Markup

=7.99$+0.96$

answer/explanation:

carry out these steps: 12% of 7.99 = $0.96 and use fraction if u may like. therefore the new cost after the markup is $7.99 + $0.96 which is then equal to your final answer - $8.95!

Answer:

b=2.6

Step-by-step explanation:

b+2=4.6

Subtract both sides by 2 to isolate b

b+2-2=4.6-2

b=2.6

Therefore, b is equal to 2.6.

Answer:

x = 17.74 cm

Step-by-step explanation:

tan 29 = x/32

0.5543 = x/32

x = 17.74 cm

Answer:

17.74  to 2 dp.

Step-by-step explanation:

tan 29 = x/32

x = 32 tan 29

= 17.7379.

Answer:

I think it's -14

Step-by-step explanation:

x = 0 so the x won't be included but

-2 • x = -2x

-12 • x = -12x

-2x + (-)12x = -14

hope this helps :)

Answer:

Convert each fraction to its percentage form:

= 36 / 40

= 90%

= 1/3

= 33.3%

= 70/100

= 70%

= 1 / 8

= 12.5%

Looking at the percentages:

= 36 / 40 is closest to 1.

= 1/3 and 70/100 are closest to one half which is 50%

= 1/8 is closest to 0.

Answer:$25.50

Step-by-step explanation:

Convert the problem to an equation using the percentage formula: P% * X = Y.

P is 10%, X is 150, so the equation is 10% * 150 = Y.

Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10. Im not sure if this is the nearest cent but here are the steps to find the nearest cent.

Answer:

A) 3 cents difference

Step-by-step explanation:

Fresh fruity mints costs 20 cents per piece:

$2.40 / 12 = 20 cents

Circle mints costs 17 cents per piece:

$5.00 / 30 = 16.6666 cents which rounds to 17

20 - 17 = 3

Answer is A

Answer:

x=1

Step-by-step explanation:

First you will distribute it

U basically multiply the 3 by the X and the 7 here

-3 x (x = -3x And the 7 becomes a 21

Then you add the 2

21 + 2 = 23

Then you add the -3

-3x + 23 =20

Then using the equation above you subtract 23 from both sides

(-3 + 23) - 23 = 20 - 23

Then you simplify it

-3x = -3

Then you divide them using the same term

  -3

÷ -3

Then you simplfy it and you get

x=1
