The required 84% of the people attending the basketball game supported the home team.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
To find the percentage of people who supported the home team, we need to calculate the proportion of people supporting the home team and convert it to a percentage.
The total number of people attending the game is,
2940 + 560 = 3500.
The proportion of people supporting the home team is,
= 2940 / 3500
= 0.84.
To convert this proportion to a percentage, we multiply it by 100:
= 0.84 × 100 = 84%
Thus, 84% of the people attending the basketball game supported the home team.

A roast turkey is taken from an oven when its temperature has reached 185°F and is placed on a table in a room where the temperature is 75°F. (Round your answers to the nearest whole number.)(a) If the temperature of the turkey is 150°F after half an hour, what is the temperature after 55 minutes?T(55) = 1 °F(b) When will the turkey have cooled to 105°?t = 2 min
Using unitary method, turkey's temperature after 55 minutes is 120.815° Also, it will take approximately 68 minutes for the turkey to cool down to 105°.
Now, According to the question:
What is unitary method?
The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Reduction in temperature after 30 minutes = 185° - 150° = 35°
Reduction in temperature after 1 minute = 35/30 = 1.167°
Reduction in temperature after 55 minutes = 55 × 1.167 = 64.185°
Temperature after 50 minutes = 185° - 64.185° = 120.815°
Decrease in temperature when the turkey has cooled down to 105° = 185° - 105° = 80°
Time taken by the turkey to cool down 80° = 80/1.167 = 68.55 minutes.

,C=
Answer:
The coefficient a = -1, b = 4, c = -1 and d = 0. To solve for the coefficients, substitute the values from the table into the equation y = ax³ + bx² + cx+d. When x = 0 and y = 0, we get 0 = -1a + 4b + c + d, so d = 0. When x = 1 and y = -2, we get -2 = -1a + 4b + c, so c = -1. When x = 2 and y = -26, we get -26 = -1a + 4b, so b = 4. Finally, when x = 3 and y = -54, we get -54 = -1a, so a = -1.

What is permutation and combination?A permutation is an act of arranging objects or numbers in order. Combinations are the way of selecting objects or numbers from a group of objects or collections, in such a way that the order of the objects does not matter.
For this, the easiest way is doing the complement. Calculate how many the 2 people are together and subtract from the total, so:
We can consider 2 people a block that will permutation, so, instead of 6 people we have 5 [a block of 2 people and 4 more):
5! = 5.4.3.2.1 = 120
The 2 people from the block will permutation as well:
2! = 2.1 = 2
Total: 5!.2! = 120.2 = 240.

A radius of a circle has endpoints (-4,3) and (1,-2). What is the equation that
defines the circle if its center is at the second quadrant?
By applying standard equation of a circle concept, it can be concluded that the equation that defines the circle is (x + 4)² + (y - 3)² = 50.
Circle is a collection of points on a plane line that are all the same distance (the radius) from a given point (the center).
Standard equation of a circle can be written as:
(x - h)² + (y - k)² = r² , where:
(h,k) = center of the circle
r = radius
We know that the radius of the circle has endpoints (-4,3) and (1,-2), which means that one of these points is the center of the circle.
Since we know that its center is in the second quadrant, we can conclude that (-4,3) is the center.
Now we can substitute these values into the equation:
(x - h)² + (y - k)² = r²
(1 - (-4))² + (-2 - 3)² = r²
5² + (-5)² = r²
25 + 25 = r²
50 = r²
As we know the r, now we can have the standard equation of the circle:
(x - h)² + (y - k)² = r²
(x - (-4))² + (y - 3)² = 50
(x + 4)² + (y - 3)² = 50
Thus the equation that defines the circle is (x + 4)² + (y - 3)² = 50.

Answer: Rounding degrees is similar as to answering decimals. How ever, there is 60 minutes in a degree. If the numbers is less than 30, you round down to the nearest degree, and if its 30 or up, you round up to the nearest degrees.
for normally distributed scores, what percentage of scores (or cases) would fall: between the mean and z = -1
Approximately 84% of scores fall between the mean and z = -1 for normally distributed scores.
In a normal distribution, approximately 68% of the scores fall within one standard deviation of the mean, both above and below. Z-scores are used to describe the location of a score relative to the mean, in terms of standard deviations.
A z-score of -1 indicates that a score is 1 standard deviation below the mean. So, if we consider all the scores that are 1 standard deviation below the mean or closer to the mean, then we would have a total of 68% of the scores, which includes the mean.
And, if we consider only the scores that are between the mean and 1 standard deviation below the mean, then we would have 84% of the scores. Hence, approximately 84% of scores would fall between the mean and z = -1 for normally distributed scores.

The solution to this system of equations is x = -6, y = 9, and z = 5.
To solve this system of equations using row operations or elementary matrices, we can first start by subtracting 4x from both sides of the first equation. This leaves us with 3x - 3x = -6. Since the x terms cancel out, this equation is now true for any value of x. We can then use this equation to substitute -6 for the x terms in the other two equations. In the second equation, we have 5y - 2y - 6 = -16. We can then subtract 5y from both sides of the equation to get -2y - 6 = -16. Dividing both sides by -2 gives us y = 9. The third equation is now 3y - 3z - 4z - 4z = -6. We can then subtract 3y from both sides of the equation to get -3z - 4z = -15. We can then divide both sides of the equation by -3 to get z = 5. Therefore, the solution to this system of equations is x = -6, y = 9, and z = 5.

Mrs mills buys 4 packs of treats for her cats, fluff and tigger. She gives fluff 1 6 of a pack each day. She gives tigger 1 5 of a pack each day. For how many complete days will the 4 packs of treats last?.
The number of complete days that 4 packs of treats will last, we need to determine the total number of packs each day and divide it into the total number of packs Mrs. Mills has bought.
Let's call the number of days the treats will last "d".
Then, the number of packs Fluff eats in "d" days is d * (1/6 of a pack per day) = (1/6)d.
Similarly, the number of packs Tigger eats in "d" days is d * (1/5 of a pack per day) = (1/5)d.
The total number of packs they eat in "d" days is (1/6)d + (1/5)d = (11/30)d.
Since Mrs. Mills has bought 4 packs, we have 4 = (11/30)d.
Finally, solving for "d", we have d = (30/11) * 4 = 120/11 days.
Since "d" must be a whole number, we round down to get 10 complete days that the 4 packs of treats will last.

Cynthia was twice as old as Abigail 3 years ago.
Let x be the number of years ago when Cynthia was twice as old as Abigail
If Abigail is 15 years old and Cynthia is 27 years old today, then "x" years ago, the algebraic expression that represents their age was"15 - x" and "27 - x", respectively.
If "x" years ago, Cynthia was twice as old as Abigail, then the equation will be
27 - x = 2(15 - x)
Simplify the equation and solve for the value of x.
27 - x = 30 - 2x
x = 3
Therefore, 3 years ago, Cynthia was twice as old as Abigail.

Note:
When solving for k, round to four
decimal places.
A country's population in 1995 was 23 million.
In 2001 it was 25 million. Estimate
the population in 2013 using the exponential
growth formula. Round your answer to the
nearest million.
P=Aekt
Enter the correct answer
A country's population in 1995 was 23 million. In 2001 it was 25 million, the population in 2013 using the exponential growth formula in 2013 will be around 30 million.
For this problem, we have the final population P, the starting population A, and the time passed t.
We still need to determine the value of the growth factor k.
This can be done using the information for the years 1995 and 2001.
In this case, A will be 23 million (the population in 1995), P will be 25 million (the population in 2001), and t will be 6 years (the number of years between 1995 and2001):
[tex]P=Ae^{kt}[/tex]
[tex]25=23e^{k 6}[/tex]
[tex]e^{6k} =\frac{25}{23}[/tex]
[tex]k = \frac{ln(25) - ln(23)}{6}[/tex]
k = 0.013897
Now, let's use this information to determine P in 2013.
A will still be 23 million, but t will be 18 years.
[tex]P= 23e^{0.013897*18} \\P= 23e^{0.250146} \\P=23 * 1.28421\\P=29.5368\\[/tex]
Therefore, the population in 2013 using the exponential growth formula in 2013 will be around 30 million.
