Your friend Shawn tells you that he had been practicing flipping coins so that they will land on heads more frequently than tails. He claims that he can now flip a coin and the probability it will land on heads is 9/10.

PART A
Do you believe him?


A
yes
B
no

Answers

Answer 1

Answer:

Yes because I believe my friend

Step-by-step explanation:

Answer 2
B no because there will always be a 50/50 or 1/2 chance of the coin landing on heads. This will only be the probability if he flips the coin correctly

Answer:

C) sinF=27/45

Step-by-step explanation:

Because both triangles are similar, that means their sides are proportional to each other. Since sin∅=opposite/hypotenuse, then if sinC=3/5, we must find a ratio that is proportional to 3/5. Option C seems to work because 27/45=3/5, so sinF=27/45

The answer is number c

Answer:

3/18 foot³

Step-by-step explanation:

okay, so the formula for volume is height x base, which is real confusing, but lets go:

first, you have to figure out the base, which is the surface that's on the bottom:

1/2 x 1/2 = 1/4

so you then multiply that by how high the figure is:

1/4 x 3/4 = 3/16

So your answer is option D. 3/18 cubic foot

2. The truth will prevail. (Justify your answers, no justification, no credit). (12 points each) a) In any given sample, the median is never larger than the mean, unless the distribution is symmetric. True or False. b) The sign of the correlation coefficient provides us with information regarding how good a line fits the data points we are studying. True or False. c) The range is always larger than the inter-quartile range. True or False

Answers

Answer:

False ;

False ;

False

Step-by-step explanation:

In a perfectly symmetric distribution, the mean and Median values are the same. But for skewed distributon, the median is greater than the mean (negatively skewed or left skewed data). Hence, the assertion is false.

The sign of the correlation Coefficient does not give information about how good a line fits. The sign attached to the correlation Coefficient gives information about the slope and hence, the type of relationship between the variables.

Positive (+) sign = positive relationship between variables ; negative (-) sign = negative relationship between variables.

C.)

The value of the range is not always higher Than the value of the interquartile range. The IQR might have the same value as the value of the range.

For instance :

Given the data :

1, 1, 1, 2, 2, 3, 4, 4, 4

Range = maximum - minimum

Range = 4 - 1 = 3

Interquartile range (IQR) :

IQR = Q3 - Q1

Q3 = 3/4(n+1)th term

Q3 = 3/4(10) = 7.5th term

Q3 = (7th + 8th) / 2 = (4+4)/2 = 4

Q1 = 1/4(10) = 2.5th term

Q1 = (2nd + 3rd) / 2

Q1 = (1 + 1) /2 = 1

Q3 - Q1 = 4 - 1 = 3

Can anyone double check this to make sure I’m correct?

The equation of the line for the given data set of scatter plots will be y =- x. Since their Mean(M) is equal.

What is the Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given a data set of the number of text messages sent (x) and text messages received (y) by 10 students in a half hour.

so

x     y

0    2

5    1

6    4

8    12

11    11

12    13

15    11

17    20

21    22

24    23

Where M of x = 11.9

also the M of y = 11.9

Sum of X = 119

Sum of Y = 119

Mean X = 11.9

Mean Y = 11.9

The sum of squares (SSX) = 504.9

The sum of products (SP) = 504.9

Regression Equation = ŷ = bX + a

b = SP/SSX = 504.9/504.9 = 1

a = MY - bMX = 11.9 - (1*11.9) = 0

ŷ = 1X - 0

Thus the equation of line best fit will be y = x.

Meg plotted the graph below to show the relationship between the temperature of her city and the number of people at a swimming pool:

Main title on the graph is Swimming Pool Population. Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of People at the Pool. Dots are made at the ordered pairs 2.5, 1 and 5, 2 and 7.5, 2 and 7.5, 3 and 7.5, 4 and 10, 5 and 10, 6 and 12.5, 6 and 15, 7 and 15, 8 and 17.5, 5 and 17.5, 7 and 20, 9 and 22.5, 7 and 22.5, 9 and 25, 11 and 27.5, 12.

Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate slope and y-intercept. (5 points)

As the temperature increases, the number of people at the pool increases.
