Answer:
The equation of the line is y = -1.x + 9
Graph is provided in the attached figure
Step-by-step explanation:
The slope intercept equation of a line in 2D(x,y) coordinates is given by the equation
\(y = mx + c\)
where m is the slope of the line and c the y-intercept i.e. where the line crosses the y axis at x = 0
Given slope = -1, we can find c and the equation of the line
Since (3,6) is a point on the graph, these coordinates must satisfy the above equation
Substitute for y = 6 and x = 3
\(6 = (-1)3 + c\\\\c = 9\\\\\textrm{Equation of line is }\\y = -1.x + 9 \\y = 9-x\)
In the attached figure you can see that (3,6) is on the line
The coach of a college basketball team categorizes the number of points
scored by the team in each game, with the categories being 51-57, 58 - 64,
65-71, and 72 or more. If the following data represent the numbers of
points scored in the last 10 games, how many games were in the 51 - 57
category?
51, 70, 63, 59, 56, 75, 60, 55, 67, 64
A. 2
B. 4
C. 1
D. 3
We can see that there are a total of 3 games that fall into the 51-57 category (games 1, 5, and 8). Therefore, the answer to the question is D. 3 games were in the 51-57 category. The correct option is D.
To solve this problem, we need to first determine which category each game falls into based on the given categories.
Game 1: 51 points - falls into the 51-57 category
Game 2: 70 points - falls into the 72 or more category
Game 3: 63 points - falls into the 58-64 category
Game 4: 59 points - falls into the 58-64 category
Game 5: 56 points - falls into the 51-57 category
Game 6: 75 points - falls into the 72 or more category
Game 7: 60 points - falls into the 58-64 category
Game 8: 55 points - falls into the 51-57 category
Game 9: 67 points - falls into the 65-71 category
Game 10: 64 points - falls into the 58-64 category
Now, we can see that there are a total of 3 games that fall into the 51-57 category (games 1, 5, and 8). Therefore, the answer to the question is D. 3 games were in the 51-57 category.
It's important to note that categorizing the data in this way is helpful for analyzing trends and patterns in the team's scoring over time, but it does not provide a complete picture of the team's performance in each game.
It's also worth considering other factors such as the team's opponents, the location of the game, and any injuries or other circumstances that may have affected the outcome.

A box has 6 blue socks and 4 white socks. find the number of ways 2 socks can be drawn from the box where
a) There are no restriction
b) They are different colours
c) They are the same colours
The number of ways to draw the socks in each case is given as follows:
a) 90 ways.
b) 48 ways.
c) 42 ways.
What is the Fundamental Counting Theorem?The Fundamental Counting Theorem states that if there are m ways for one trial and n ways for another trial, then there are m x n ways in which the two trials can happen simultaneously.
This can be extended to more than two trials, where the number of ways in which all the trials can happen simultaneously is the product of the number of outcomes of each individual trial, according to the equation presented as follows:
\(N = n_1 \times n_2 \times \cdots \times n_n\)
For item a, we have that there are no restrictions, hence there are 10 options for the first sock and 9 for the second, hence:
10 x 9 = 90.
For item b, we need one of each, hence the possible combinations are:
One of six(blue) and then one of four(white).One of four(white) and then one of six(blue).Hence:
6 x 4 + 4 x 6 = 48.
For item c, we can take 6 then five(two blue) or 4 then 3(two white), hence:
6 x 5 + 4 x 3 = 42.

1/2(6x - 10) - x =
write the other side of this equation so it's true for no values of x:
1/2(6x - 10) - x =
The other side of this equation so it's true for all values of x: 1/2(6x - 10) - x = 2x - 5, and the other side of this equation so it's true for no values of x: 1/2(6x - 10) - x = 2x-5 = 2x+3.
How do equations work?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
Given that, find the other side of this equation so it's true for all values of x:
1/2(6x - 10) - x
= 6x/2 - 10/2 -x
= 3x-5-2
= 2x-5
Now for, equation so it's true for no values of x:
1/2(6x - 10) - x =
Distribute the parentheses:
1/2(6x - 10) - x =
= 3x -5 -x
= 2x -5
We need to other side to be of the form 2x - constant where the constant is not equal to 5.
2x-5 = 2x+3
Subtract 2x from each side.
-5 =3
This is not true so there is no solution.
Hence, the other side of this equation so it's true for all values of x: 1/2(6x - 10) - x = 2x - 5, and the other side of this equation so it's true for no values of x: 1/2(6x - 10) - x = 2x-5 = 2x+3.

Carl Cornfield represented the acres he planted with a Venn diagram. A = {corn}; B = {wheat}; U = {all grain}. Answer the following questions: How many acres were planted in just corn? How many acres were planted in just wheat? What is the intersection of corn and wheat? What is the union of corn and wheat?
Answers:
Just corn = 10 acresJust wheat = 7 acresIntersection of corn and wheat = 4 acresUnion of corn and wheat = 21 acres===========================================
Explanation:
The number 10 inside circle A, but outside circle B, represents the number of acres dedicated to corn only (no wheat).
The number 7 inside circle B, but outside circle A, represents the number of acres dedicated to wheat only (no corn)
The number 4 in the overlapping region of both circles represents the number of acres for both corn and wheat at the same time.
The union of two sets is simply combining the two sets together to form one bigger set. If an element is in A union B, then it is either in A or B, or both. We add the values in the circles to get 10+7+4 = 17+4 = 21 to represent 21 acres for corn only, for wheat only, or for both.
Note: There are no values outside the circles, so none of the land is for any other purpose other than corn or wheat.

About 217,000 high school students took the AP Statistics exam in 2017. The free-response section of the exam consisted of five open-ended problems and an investigative task. Each free-response question is scored on a 0 to 4 scale (with 4 being the best). For one of the problems, a random sample of 30 student papers yielded a mean score of x =1.267 and a standard deviation of 1.230. a. Find and interpret the standard error of the mean. b. Construct and interpret a 90% confidence interval to estimate the true mean score on this question.
The standard error is of 0.2246, which means that the mean scores for samples of 30 vary around 0.2246 from the mean.
What is a confidence interval?The confidence interval is the range of values that you expect your estimate to fall between a certain percentage of the time if you run your experiment again or re-sample the population in the same way.
The confidence interval formula is \(\bar x\pm t\frac{s}{\sqrt{n}}\).
Where, \(\bar x\) is the sample mean, t is the critical value, n is the sample size and s is the standard deviation for the sample.
Here,
\(\bar x\) =1.267, s=1.23, n=30
The standard error is Se= 1.23/√30
= 0.2246
Item a:
The standard error is of 0.2246, which means that the mean scores for samples of 30 vary around 0.2246 from the mean.
Item b:
Using a t-distribution calculator, considering a confidence level of 0.99 with 30 - 1 = 29 df, the critical value is t = 2.7564.
\(\bar x\pm tS_c\)
\(\bar x+ tS_c\) =1.267-2.7564(0.2246) =0.6479
\(\bar x- tS_c\) =1.267+2.7564(0.2246) =1.8861
Therefore, the 99% confidence interval to estimate the true mean score on this question is (0.6479, 1.8861). It means that we are 99% that the true mean score of all students in this question is between 0.6479 and 1.8861.

B= the person chosen is overweight, but not obese.
According to the National Center for Health Statistics,
P(A)=0.38
P(B)=0.33
1. Explain why events A and B are disjoint.
a. Because event B rules out obese subjects.
b. Because an obese person is certainly overweight.
c. Because some people may be considered obese and overweight.
d. Because some people are not obese nor overweight.
2. Say in plain language what the event "A or B" is.
a. "A or B" is the event that the person chosen is overweight or obese.
b. "A or B" is the event that the person chosen is overweight and obese.
c. "A or B" is the event that the person chosen is overweight or obese or both.
d. "A or B" is the event that the person chosen is not obese or not over weight.
Answer:
a. Because event B rules out obese subjects.
b. "A or B" is the event that the person chosen is overweight and obese.
Step-by-step explanation:
1. Disjoint events are those events which do not have the same elements. Event A and event B can only be disjoint if they both have separate subjects that is event A contains obese persons and event B contains overweight persons.
Therefore they are only disjoint when set B rules out ( leaves out) obese people. So choice a is the best answer.
Disjoint events are also called mutually exclusive events
2. In statistics the symbol or means including. Event A or B would mean including both types of person obese and overweight. In mathematical expression it is written as
P (A or B) = P (A) + P (B) For mutually exclusive events. ( disjoint events)

The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.

Emil is running a lemonade stand. He sells half of his lemonade in the morning, a quarter of what was left at lunchtime, and a third of what ws left in the afternoon. When he closes for the day, he has 4 liters left. How many liters of lemonade did he start the day with? math
Emil starts the day with 16 liters of lemonade if he is left with 4 liters by the end of the day. Computed using the fractional values given.
Let the initial quantity of lemonade with Emil be x liters.
Quantity sold by Emil in the morning = Half of his lemonade = (1/2)x liters, that is half fraction of x.
Quantity left with Emil = x - x/2 = x/2 liters, that is half fraction of x.
Quantity sold by Emil at lunchtime = Quarter of what was left = (1/4)(x/2) liters = x/8 liters, that is the one-eight fraction of x.
Quantity left with Emil = x/2 - x/8 = 3x/8 liters, that is the three-eight fraction of x.
Quantity sold by Emil in the afternoon = One-third of what was left = (1/3)(3x/8) liters = x/8 liters, that is the one-eight fraction of x.
Quantity left with Emil = 3x/8 - x/8 = x/4 liters, that is the quarter fraction of x.
Now, we are said that Emil closes for the day with 4 liters remaining.
Therefore, x/4 = 4, or, x = 4*4 = 16 liters.

h is the height
Since the base is 4, then
b = 4
Substitute the values of b and h in the rule of the area to find it
\(\begin{gathered} A=\frac{1}{2}\times4\times2\sqrt{3} \\ \\ A=4\sqrt{3}\text{ cm}^2 \end{gathered}\)(b)
The area of the base is
\(A=4\sqrt{3}\text{ cm}^2\)Since the altitude of the pyramid is 4 cm
We will use the Pythagoras theorem to find the side SC
From the triangle above we will use the height of the pyramid OS and a part of the height of the base = 2/3 h to find the side SC
\(\begin{gathered} SC^2=4^2+(\frac{2}{3}\times2\sqrt{3})^2 \\ \\ SC^2=16+(\frac{4}{3}\sqrt{3})^2 \\ \\ SC^2=16+\frac{16}{3} \\ \\ SC^2=\frac{64}{3} \end{gathered}\)Take a square root for both sides
\(\begin{gathered} SC=\sqrt{\frac{64}{3}} \\ \\ SC=\frac{8}{\sqrt{3}}\times\frac{\sqrt{3}}{\sqrt{3}} \\ \\ SC=\frac{8}{3}\sqrt{3} \end{gathered}\)(c)
The length of the side edge SC is
\(SC=\frac{8}{3}\sqrt{3}\text{ cm}\)
