You claim you are psychic and can predict a coin flip 60% of the time. To test your claim, your friend has you predict a coin flip and then records whether or not you are correct. You do this 200 times and find you are right 135 times. Considering a null hypothesis that you are correctly predict the coin flip 60% of the time, using a hypothesis test, which of the following statements is most accurate?

a. You cannot reject the null at the 10% level of significance.
b. You can reject the null at the 10% level of significance, but cannot reject the null at the 5%, 2%, or 1% level of significance.
c. You can reject the null at the 10% and 5% level of significance, but cannot reject the null at the 2%, or 1% level of significance.
d. You can reject the null at the 10%, 5%, and 2% level of significance, but cannot reject the null at the 1% level of significance.
e. You can reject the null at the 10%, 5%, 2%, and 1% level of significance

Answers

Answer:

You can reject the null at the 10% and 5% level of significance, but cannot reject the null at the 2%, or 1% level of significance. ( D )

Step-by-step explanation:

let : P = 0.6

x = 135 , n = 200

p = 135 / 200 = 0.675

H0 : P = 0.6

Ha : P ≠ 0.6

performing the test statistic = ( 0.675 - 0.6 ) / [tex]\sqrt{\frac{0.60(1-0.60)}{200} }[/tex]

= 0.075 / 0.0346 ≈ 2.17

p-value = 2 * P ( Z > - 2.17 )  ( using excel function ; NORMSDIST )

            = 2 * 0.015  = 0.03  

A scale model of an object has a scale of 1cm : 2ft. The actual object is 11 feet tall. How tall is the model?

Answers

Given:

The scale model of an object has a scale of 1cm : 2ft.

The actual object is 11 feet tall.

To find:

The height of the model.

Solution:

It is given that the scale model of an object has a scale of 1cm : 2ft and the actual object is 11 feet tall.

Let the height of the model be x cm.

[tex]\dfrac{x\ cm}{11\ ft}=\dfrac{1\ cm}{2 \ ft}[/tex]

[tex]x\ cm=\dfrac{1 \ cm\times 11\ ft}{2 \ ft}[/tex]

[tex]x\ cm=5.5\ cm[/tex]

Therefore, the model is 5.5 cm tall.

Discount = 14.99 × 15/100

Discount = 14.99 x 0.15

You save = $2.25

Final Price = Original Price - Discount

Angle #1: 115°

Angle #2: 64°

Angle #3: 90°

Angle #4: 106°

Angle #5: 165°

Step-by-step explanation:

you subtract the ones that give you the exterior angle by 180 because it is a supplementary angle. that means that both angles add up to 180. the little square next to angle three means its a right angle. this means it is exactly 90°. the last angle is a little tricky. you need to add up all the angles you have and then you if you get 540 then your answer is correct because all interior angles of a pentagon must add up to 540.

HELP. photo added. answers are 45, 20 , it 22.5

Answers

Answer:

22.5°

Step-by-step explanation:

We know that the measure of straight line is 180° . Therefore the sum of all angles will be 180° .

⇒ 90° + x + 3x = 180°

⇒ 90° + 4x = 180°

⇒ 4x = 90°

⇒ x = 90°/4

x = 22.5°

Hence the value of x is 22.5°

Which angle is coterminal with a 645° angle?
A. An angle measuring 265°
B. An angle measuring 75°
O C. An angle measuring 285°
D. An angle measuring 345º

Answers

Answer:

C

Step-by-step explanation:

Coterminal angles are angles that have a common terminal side.

So, given an angle θ, its coterminal angles will always be ±360°. This can be repeated.

We have a 645° angle.

Therefore, all values of the equation:

[tex]645\pm 360n[/tex]

Where n is an integer is coterminal with our original angle.

Letting n = 1 and using the negative case, we acquire:

[tex]\Rightarrow 645-360=285[/tex]

Therefore, an angle measuring 285° is coterminal with a 645° angle.

None of the other options can be reached by adding/subtracting 360.

Therefore, our answer is C.

Which one is the answer

Answers

Answer:

x = 30 degrees

Step-by-step explanation:

a triangle's angles should all add up together to 180 degrees. Since a right angle is 90 degrees then you have your 60 degree angle that only leaves 30 degrees left.

Answer: A and C

Step-by-step explanation:

A is right because it’s right triangle since it has a right angle. C is also right, x=30 because we have 60 degrees and 90 degrees. 60 plus 90 is 150 and a triangle is equal to 180 degrees 180-150 is 30

What is the solution of the system of equations? -4x+3y=-12 -2x+3y=-18

*Note: I believe it has no solution, but I would like to make sure. Thank you all for your help.

Answers

Answer:

Step-by-step explanation:

I've enclosed a graph to show you that there is one solution.

-4x + 3y = - 12

- 2x + 3y = - 18           Subtract

-2x = 6                        Divide by - 2

-2x/-2 = 6/-2

x = - 3

- 4x + 3y = - 12

-4(-3) + 3y = - 12

12 + 3y = - 12

3y = - 12 - 12

3y = - 24

3y/3 = - 24/3

y = - 8

Which is exactly what the graph shows.

You can tell immediately that this has 1 or more solutions just by looking at the number in front of x and y in each each equation.

It's always a good idea to graph a question like this one. Desmos is a pretty good tool to use if you don't have a graphing calculator.

The y's are the same so you are 1/2 way home in saying what you did.

The x's are different so that means you have at least 1 solution.

Answers

Answer:

4) 24

Step-by-step explanation:

OA = OB = 7 ( radius )

OP = OB + BP

= 7 + 18

OP = 25

In triangle OPB,

By Pythagoras theorem,

( OP )² = ( OA )² + ( AP )²

( AP )² = ( OP )² - ( OA )²

= 25² - 7²

= 625 - 49

( AP )² = 576

AP = 24

Answer:

your answer will be 24

Step-by-step explanation:

∠OAP=90°

OA=OB=7

[tex]OA^{2} +Ap^{2} =OP^{2} \\\\7^{2} +Ap^{2} =(7+18)^{2} \\\\Ap^{2} =25^{2} -7^{2} =576\\\\AP=\sqrt{576} =24\\\\Ap=24[/tex]

Area of the circle [tex] =\pi r^2 [/tex]

[tex] 7\pi=\pi r^2 [/tex]
