Step 2: Find Circumference

Answer:

a) Mean is -23.47

b) Variance is 206.59

c) standard deviation is 14.37

Step-by-step explanation:

Given that;

 x              −41        −27        −8         −3

P(X = x)      0.29      0.35      0.21      0.15

X.P            -11.89     -9.45    -1.68     -0.45

a) mean

Mean = ∑X.P = -11.89 +  -9.45 + -1.68 + -0.45

Mean = -23.47

b)  the variance

E(x²) = ∑x²P(X=x)

= (−41²×0.29) + (−27²×0.35) + (−8²×0.21) + (−3²×0.15)

= 487.49 + 255.15 + 13.44 + 1.35

= 757.43

So

Var(X) = E(x²) - [∑X.P]²

Var(X) = 757.43 - [-23.47]²

= 757.43 - 550.8409

= 206.5891 ≈ 206.59

Therefore Variance is 206.59

c) standard deviation

standard deviation SD(X) = √Var(X)

SD(X) = √206.5891

= 14.3732 ≈ 14.37

Therefore standard deviation is 14.37

its an isosceles triangle bc two sides are equal.

Answer:

-7/1

Step-by-step explanation:

any number over 1 in a fraction is the number on the top of one for example

2/1 is 2 and 100/1 is 100 and even -7/1 is -7

Answer:

11.25

Step-by-step explanation:

it is a dialation of 2.25:

12 x 2.25 = 27

and

8 x 2.25 = 18

so...

5 x 2.25 =

11.25

Answer:

Step-by-step explanation:

y-7= -4/3 (x+6)

y-7= -4/3x-8

add 7 to both sides

y= -4/3x-1

The equation in slope-intercept form for the given line is 3y = -4x -3

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that a line passes through the point (-6,7) and has a slope of -4/3.

Standard equation of a line = y = mx + c where m is the slope,

Therefore, putting values of x and y to get the value of c

7 = -6*-4/3 + c

c = 7 - 8

c = -1

Equation = y = -4x/3 -1

Or, 3y = -4x -1

Hence, the equation of a line passing through the point (-6,7) and has a slope of -4/3 is 3y = -4x -1

HAVE A GOOD DAY!

Here,

Let the total number of students be x,

Then,

55% of x=550

x=1000

Answer:

i like to do the box method which would look like

x%      l  x           - original number

---------------  

100%  l  x

which would look like for this equation

45%      l  550

---------------  

100%    l  x

so you would times 550 by 100 and get 55000 then divide by 45 which is 1222. 22 repeating but there is no one half of a person so rounded up to 1222.00

1222 is your answer

Step-by-step explanation:

You are beautiful. You are amazing. You are wonderful. You are perfect just the way you are. Never worry about the way people think about you. Only worry if you like you. You are the most important person to yourself. Just be yourself. No can tell you who you can be. You are truly perfect just the way you are. Never tell yourself you are not good enough, you are enough. Never tell yourself "I'm ugly" you are beautiful. Never let yourself down.

Death. Hate. Blood. Sorrow. Regret. Judgement. Disgusted. Disrespect. Threats. Murder. Darkness. Sadness. Fearfulness. Tortured. Humiliated. Worry. Hopelessness. Depressed. Lost. Lonely. Suffering. Disappointment. Shame. Lies. Miserable.

There are so many words that can describe our world today. We are stuck in a world a darkness, we are stuck in a world of death. The is hat going everywhere, even if we try to get out of this hate, we are still living in hate. We can try over and over again to change, but there is always something that is going to stop us. There is always something that is going to keep us from moving forward.

We need to find a way to break away the things that stop us from becoming better, we need to learn better wats to live. It does not matter who you are, what you look like, just remember you are perfect just the way you are. We can be amazing, we can be change to our society.

We are acting like everything is alright, when we actual want to break down and cry. We are acting like we are brave, when we are scared and afraid. We are acting like when can do anything, when we think we can't do anything. We are acting like we love those who hate us because we are to afraid to say the truth. We are acting like people who are to afraid to show who they really are. We are acting like life is a fairytale, but it's actual a nightmare. We are acting like we are the most happiest people, but really we just want to curl up inside. We are acting like we want to stay, when we want to run away. We are acting like we a doing just fine, When we are about to give up. We need to change, don't worry about those who hate. Don't worry about the way you look. Don't worry about who you really are. Just be yourself. Just relax. Just the real person you our. It doesn't matter what they say. The only thing that matters is if you like you the real you, not someone you are trying to pretend to be, but the real you.

There is always love, when there's only hate. There is always hope, when hope seems lost. There is always someone, when we have no one. There is always a light, when in there is darkness. There is always a way out, when we are stuck. There is always happiness, when we feel only sadness. There is always angels, when we only see demons. There is always someone to talk to, when there seems no one to talk to. There is always beauty, when things get ugly. There is always hope. There is always love. There is always someone. There is always a light. We might want to give up. We might want to lose the fight. We might want to stop trying. We might want to run away. No matter what, no matter what's happening right now, no matter if there seem like everything is falling apart or there is just a feeling that you need to give up. Always remember there is someone out there who needs you. There is always someone to talk to. There is always hope. Don't give up, don't give up. As there is always love, hope and happiness.

Sometimes in life we need a dose of happiness, sometimes we need someone to talk to, sometimes we need someone to hold on to, but sometimes we just wanna be alone, sometimes we need no one to talk to or hold. Their are those with nothing at all and there are those who have everything, but sometimes we have nothing but still everything, sometimes we have everything but nothing. Sometimes we wonder, sometimes we don't. Sometimes we try but fail and sometimes we don't try but yet succeed. Sometimes we cry, sometimes we get mad. Sometimes we do wrong, sometimes we do right. Sometimes we hate, sometimes we love. Sometimes we get our heart broken, sometimes we break peoples heart. Sometimes we tell the truth, but we are still lying. Sometimes we just need to relax but yet we can't. Sometimes we need quiet in a big city. Sometimes we are afraid of the unknown and sometimes we are not. Sometimes we discover. Sometimes we challenged. Sometimes we fall in love. Sometimes we find joy in a room of sadness. Hope this helps, have a wonderful day.

Step-by-step explanation:

if u look at the triangle it would show you

Answer:

40 degrees

Step-by-step explanation:

since JKM is congruent to PQR then,

Q is congruent to K so they have the same measure.

Answer:

Yes

Step-by-step explanation:

Using the triangle formula: a+b>c , b+c>a , and c+a>b, we can conclude that these values can form a triangle because 14+18>19 , 14+19>18 , and 18+19>14.

Answer:

To confirm if this can form it, we take the lower of the two numbers , square them, and equal it to the biggest number squared. (AKA The Pythagorean Theorem).

Step-by-step explanation:

[tex]14^{2} +18^{2} = 19^{2}[/tex]

Now solve to see if it equates to be true.

196 + 324 = 361

520 [tex]\neq[/tex] 361

That means 14, 18, and 19 can't form a triangle.

Answer:  John is 18 now

Step-by-step explanation:

If his age 5 years ago was half of his age 8 years from now, the equation can show that doubling that age will be equal to his current age plus  8 years.

2(x-5) = x + 8 .  diistribute

2x - 10 = x + 8  Subtract x from both sides 2x -x +10 = x-x +8

x -10 = 8 . Add 10 to both sides . x -10 +10 = 8 + 10  simplify.

x = 18

Check:

18-5=13,  18+8= 26 .  13 is half of 26. True.

Answer:

Statement A is TRUE.

Given an x value of 15, y would be ;

= 2.72 * 15

= 40.8

Coordinates would therefore be (15, 40.8)

Statement B is FALSE.

The coordinates of Y given are impossible given the coordinates of X. In this scenario, Y must always be greater than X as a result of the equation.

Statement C is TRUE.

The slope in the equation takes the form of the $2.72 price being charged per gallon of gasoline such that the total price of x gallons can be calculated by multiplying the number of gallons by $2.72

Statement D is FALSE.

If the price of gasoline were to decrease by $0.03, the slope would become 2.69 not 2.75. 2.75 would be the new slope if the price had increased by $0.03 instead of decreased.

Answer:

10 km

Step-by-step explanation:

volume of cube = s^3

1 m = 100 cm

volume = s^3 = (1 m)^3 = (100 cm)^3 = 1,000,000 cm^3

Since 1 m^3 = 1,000,000 cm^3, when you lay down the 1-cm cubes in a straight line with the edges touching, the line is 1,000,000 cm long.

1,000,000 cm = 10,000 m = 10 km
