Answers
If two sets are negatively correlated, as the values in one of the sets increase, the values in the other set tend to decrease.
What is the correlation of the sets?For a message to be processed by a certain orchestration, a correlation set specifies a collection of qualities and values for these properties. A maximum of three parameters are supported by each correlation set.
If two sets are negatively correlated, as the values in one of the sets increase, the values in the other set tend to decrease.
This means that there is an inverse relationship between the two sets, such that when one variable increases, the other variable tends to decrease.
This type of correlation is often expressed by a negative correlation coefficient,
which ranges from -1 to 0, with -1 indicating a perfect negative correlation.

b. 190.07 yd2
c. 603.19 yd2
d. 96.4 yd2
Please help me get this answer correct ! asap
Answers
L= r x [tex] \pi [/tex] x l
where: L = Lateral area
l = length or height
r = radius
[tex] \pi [/tex] = 3.1416
Now sorting out your given:
base = 10 yd
Height = 12.1 yd
To work out the lateral area, you will need the radius. Your base 10 yd, is the measure from one side to the other of the circle base, this is what you call diameter. What you need is radius, which is the measure of a circle from the middle of the circle to the outside, so it is half of a diameter.
So to get radius (r), divide the base by 2.
r = 10yd/2 = 5yd
Now that you have all that you need just input it into your formula:
L = r x [tex] \pi [/tex] x l
= 5 yd x [tex] \pi [/tex] x 12.1 yd
= 190.07 yd[tex] ^{2} [/tex]
So your answer is B.
base=10 yd-----------------> r=5 yd
lateral area=pi*r*h--> pi*5*12.1= 190.07 yd²
the answer is option b. 190.07 yd2

Janet has a square-shaped sheet of wrapping paper. To cover the top of a box, she cuts off 11 centimeters of the sheet along the width. The new area of the sheet is given by the expression below, where x represents the length, in centimeters, of the sheet of wrapping paper before being cut.
x^2-11x
Which statement best describes the term 11x?
the area cut from the sheet of wrapping paper
the area of the sheet of wrapping paper after being cut
the area of the sheet of wrapping paper before being cut
the width of the sheet of wrapping paper after being cut
Answers
The expression she has, x² - 11x, represents the area of the sheet of wrapping paper after she's cut it.
Answer:
The correct option is 1. It means 11x is the area cut from the sheet of wrapping paper.
Step-by-step explanation:
The shape of sheet is square.
Let x represents the length, in centimeters, of the sheet of wrapping paper before being cut.
The area of a square is
[tex]A=a\times a[/tex]
Where, a is side length.
The area of sheet before being cut is
[tex]A=x\times x=x^2[/tex]
The width of the piece cut from the sheet is 11 and length is x. So, the area of piece is
[tex]A=x\times 11=11x[/tex]
The remaining area of sheet is
[tex]A=\text{Area of sheet}-\text{Area of piece cut from the sheet}[/tex]
[tex]A=x^2-11x[/tex]
Therefore correct option is 1. It means 11x is the area cut from the sheet of wrapping paper.
Jake carries a green and yellow and a black guitar pick in his pocket he randomly chooses a guitar pick from his pocket before every concert what is the probability will he select the same color pic for two concert in a row?
Answers
Answer:
[tex]\bf\textbf{The required probability = }\frac{4}{9}[/tex]
Step-by-step explanation:
The total number of ways that he can pick a pic are 3 × 3 × 3 = 27 ways
If Jake selects the black pic in the first concert, then number of ways of success are :
B B G
B B Y
B G G
B Y Y
Total number of success = 4
If Jake selects the green pic in the first concert, then number of ways of success are :
G G B
G G Y
G B B
G Y Y
Total number of success = 4
If Jake selects the yellow pic in the first concert, then number of ways of success are :
Y Y B
Y Y G
Y B B
Y G G
Total number of success = 4
Therefore, in all the three cases total number of successes are :
4 + 4 + 4 = 12
[tex]Probability = \frac{\text{Number of successful ways}}{\text{Total number of ways}}\\\\\implies Probability = \frac{12}{27}=\frac{4}{9}[/tex]

The graph below shows the height of a kicked soccer ball f(x), in feet, depending on the distance from the kicker x, in feet: Part A: What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing, and what do they represent about the distance and height? (6 points) Part B: What is an approximate average rate of change of the graph from x = 22 to x = 26, and what does this rate represent? (4 points
Answers
the complete question in the attached figure
part A
the x intercept 0 is the point where the ball was hit, the x intercept 20 is the point where the ball fell back to the ground, 20 feet away from the kicker.
the function is increasing in the interval x∈(0, 10) and decreasing in x∈(10, 20)
this means that the height is increasing in the interval (0, 10) and decreasing as x goes through the interval (10,20)
the distance from the kicker is increasing during the whole interval (0, 20)
part B
the rate of change represents the slope of the secant line from A to B. It approximates the rate at which f(x) decreases or increases in the interval
x =[A, B]
Judi is 9 years older than Baz.Baz is twice as old as Caleb.All their ages add up to 64.What are their ages?
Answers
Baz is 22
Caleb is 11
Caleb is 11 years old, Baz is 22 years old, and Judi is 31 years old, which adds up to 64 years in total.
If Caleb's age is C, then Baz, being twice as old, is 2C. Judi is 9 years older than Baz, so her age is 2C + 9.
C + 2C + 2C + 9 = 64
5C + 9 = 64
Subtracting 9 from both sides gives:
5C = 55

n=10 = number of observations in each list.
We need the correlation coefficient ρ to select the right choice of answers.
We first calculate the mean μ and standard deviation σ of each list
[tex]\mu_s=\sum_{i=1}^{10}S_i=41.0[/tex]
[tex]\sigma^2_s=\sum_{i=1}^{10}(S_i-\mu_s)^2/n=83[/tex]

[tex]\mu_t=\sum_{i=1}^{10}T_i=74.24[/tex]
[tex]\sigma^2_t=\sum_{i=1}^{10}(T_i-\mu_t)^2/n=15.4524[/tex]
[tex]\sigma_t=\sqrt{\sigma^2_t}=\sqrt{15.4524}=3.9310[/tex]
We are now ready to calculate the correlation coefficient ρ :
[tex]\rho=\frac{E[(S-\mu_s)(T-\mu_t)]}{\sigma_s*\sigma_t}[/tex]
[tex]=\frac{\sum_{i=1}^{n}[(S_i-\mu_s)(T_i-\mu_t)]/n}{\sigma_s*\sigma_t}[/tex]
[tex]=\frac{\sum_{i=1}^{n}[(S_i-\mu_s)(T_i-\mu_t)]/n}{9.1104*3.9310}[/tex]
[tex]=\frac{35.27}{35.8127}[/tex]=0.9848
Because the correlation coefficient, ρ , is close to one, the ice cream sales increase markedly with a rise in temperature.
Note:
a correlation close to 1 means both increase (or decrease)
a correlation close to -1 means one increases while the other decreases
correlation close to 0 means one does not quite affect the other.

Joseph squares a number and subtracts 8 from the answer. He then divides this result by 7. Finally he adds 12 and the result is now 20. What was Joseph's original number?
Answers
[tex]( {x}^{2} - 8) \div 7 + 12 = 20[/tex]
[tex]( {x}^{2} - 8) \div 7 = 8[/tex]
[tex]( {x}^{2} - 8) = 56[/tex]
[tex] {x}^{2} = 64[/tex]
[tex]x = \sqrt{64} \: \: \: \: \: x = - \sqrt{64} [/tex]
[tex]x = 8 \: \: \: \: \: x = - 8[/tex]
Final answer:
We use reverse operations to solve Joseph's equation and find that the original number could have been either 8 or -8.
Explanation:
The question asks us to determine Joseph's original number based on a series of mathematical operations. We can set up an equation to represent the problem statement: let x be the original number. The sequence of operations given is:
Square x and subtract 8.
Divide this result by 7.
Add 12 to the result from step 2.
The final result is 20.
Representing this mathematically: ((x2 - 8) / 7) + 12 = 20. To find x, we need to work backward through these operations:
Subtract 12 from both sides: ((x2 - 8) / 7) = 8.
Multiply both sides by 7: x2 - 8 = 56.
Add 8 to both sides: x2 = 64.
Take the square root of both sides: x = 8 or x = -8 (considering both positive and negative square roots).
Therefore, Joseph's original number could have been either 8 or -8.

Every cereal box has a gift inside, but you cannot tell from the outside what the gift is. the store manager assures you that 13 of the 47 boxes on the shelf have the secret decoder ring. the other 34 boxes on the shelf have a different gift inside. if you randomly select two boxes of cereal from the shelf to purchase, what is the probability that both of them have the secret decoder ring?
Answers
The probability that both selected boxes have the secret decoder ring is approximately 7.20%
Explanation:To find the probability that both selected boxes have the secret decoder ring, we can use the concept of independent events. Since the boxes are randomly selected, the probability of selecting a box with the secret decoder ring is 13/47 for the first box. After selecting the first box, there will be 12 boxes with the secret decoder ring left out of 46 total boxes. So, the probability of selecting a second box with the secret decoder ring is 12/46. To find the probability of both events occurring, we multiply the probabilities: (13/47) * (12/46) = 156/2162 ≈ 0.07197 or about 7.20%
