The points scored by the remaining players on the team is 31 points.
What is percentage?A component or fraction of a whole can be expressed as a percentage by using a number out of 100. Mathematicians frequently use comparison to represent changes in quantities over time or to compare two numbers. For instance, if a student receives an 80 percent on a test, they properly answered 80 of the 100 questions.
For performing a range of mathematical operations, such as determining the percentage rise or decrease of a quantity or computing interest rates on loans or investments, percentages can be expressed as fractions or decimals.
From the given percentages the total percent is:
Total percentage = 15% + 10% + 13% = 38%
Now, from 100 the remaining percentage is: 100% - 38% = 62%
For the remaining players the score is given as:
Remaining points = 50 * (62/100) = 31
Hence, the points scored by the remaining players on the team is 31 points.

The probability of event A occurring is 0. 65. The probability of events A and B occurring together is 0. 33. Events A and B are independent. The probability of event B is 0.68.
Probability:
The probability of an event is a number that indicates the probability of the event occurring. Expressed as a number between 0 and 1 or as a percent sign between 0% and 100%. The more likely an event is to occur, the greater its probability. The probability of an impossible event is 0; the probability of a certain event occurring is 1. The probabilities of two complementary events A and B - either A occurring or B occurring - add up to 1.
Given that:
P(A) =0.65
P(A∩B) = 0.33
And event A and B are independent.
Using the probability formula:
P(B) = 1 - P(A) + P(A∩B)
⇒ P(B) = 1 - 0.65 + 0.33
⇒ P(B) = 0.68

Over 9 days Jaison jogged ----- 10m, 6m, 6m, 7m, 5m, 7m, 5m, 8m, 9m
Find the mean distance Jaison jogged
The mean distance Jaison jogged over 9 days is 7 meters per day. This was calculated by adding up all the distances he jogged and dividing by 9.
To calculate the average distance that Jaison jogged over the 9 days, we used the formula for mean, which involves summing up all the distances he jogged and dividing by the total number of days. After adding up the distances, we found that the total distance Jaison jogged was 63 meters. Dividing this by the 9 days gives us an average distance of 7 meters per day. Therefore, Jaison jogged an average of 7 meters each day over the 9-day period.

a bin can hold 28 pounds. each toy car weighs 7 ounces. how many toy cars can the bin hold? (2 points) 64 toy cars 72 toy cars 88 toy cars 92 toy cars
A bin can hold 28 pounds. each toy car weighs 7 ounces., so the bin can hold 64 toy cars.
How to determine the number of toy carsTo determine the number of toy cars the bin can hold, we must first convert the weight limit of the bin and the weight of the toy cars to a uniform unit of measure.
We'll then divide the weight limit of the bin by the weight of one toy car. After that, we'll multiply the resulting value by the number of ounces in one pound (16).
Here's how to solve the problem:
1 pound = 16 ounces
Therefore, a bin that can hold 28 pounds can hold:28 × 16 = 448 Ounces
The weight of one toy car is 7 ounces.
Divide the weight limit of the bin (448 ounces) by the weight of one toy car (7 ounces):
448 ÷ 7 = 64
Therefore, the bin can hold 64 toy cars.

Describe p-value?The p-value in statistics is a gauge of the weight of proof opposing a null hypothesis. In the event that the null hypothesis is correct, it is the likelihood of getting a test statistic that is equally extreme or more extreme than the observed value.
The null hypothesis in hypothesis testing is a claim made about the demographic parameter under investigation. In place of the null hypothesis, a different claim is made about the demographic parameter in the alternative hypothesis. The p-value is used to assess whether the recorded data strongly support the alternative hypothesis over the null hypothesis.
The p-value, under the assumption that the null hypothesis is correct, is the likelihood of getting a result that is equally extreme or more extreme than the observed result. In this instance, the null hypothesis is that less than or equivalent to 65% of eligible voters cast ballots.
We are unable to reject the null hypothesis because the p-value (0.08), which is higher than the 1% threshold of significance, is not zero. This implies that we lack sufficient evidence to draw the conclusion that more than 65% of eligible voters cast ballots.

The value of lim f(x)g(x) as x approaches infinity is 0.
L'Hopital's rule is a mathematical tool used to evaluate limits of functions that are in an indeterminate form.
To find the limit of f(x)g(x) as x approaches infinity, we can use L'Hopital's rule since it is an indeterminate form of infinity times zero. We have:
lim x→[infinity] f(x)g(x) = lim x→[infinity] [(3x + 2e^(-3x))(1/x + 4)]
= lim x→[infinity] [(3 + 2e^(-3x)/x)/(1/x + 4)^(-1)]
Applying L'Hopital's rule to the fraction in the numerator, we get:
lim x→[infinity] [(2e^(-3x)(-3)/x^2)/(1/x + 4)^(-1)]
= lim x→[infinity] [(6e^(-3x)/x^2)/(1/x + 4)]
= lim x→[infinity] [(6e^(-3x)/(x + 4x^2))]

How are quadratic equations solved, and what are they?A polynomial equation of degree two is a quadratic equation, indicating that the variable's maximum exponent is 2. There are various ways to solve a quadratic equation, including factoring, completing the square, and applying the quadratic formula. Finding two quadratic expression factors that multiply to produce the constant term c and add to produce the linear term b's coefficient is known as factoring. The quadratic expression is completed by adding and removing a constant component to create a perfect square trinomial that can be factored or solved by calculating the square root.
In the given figure connect the points QF and QG using a line segment, thus forming two right angled triangle.
The perpendicular segment QA divides the base into two equal parts. Thus, the base of the triangle is 8.
Using the Pythagorean theorem we have:
(QF)² = (8)² + (4x + 3)²
QG² = 8² + (7x - 6)²
In the figure QF = QG = r thus:
(8)² + (4x + 3)² = 8² + (7x - 6)²
Expanding using the algebraic identity:
16x² + 24x + 9 = 49x² - 84x + 36
33x² - 108x + 27 = 0
3(11x² - 36x + 9) = 0
Using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
Substitute the values a = 11, b = -36, and c = 9:
x = (-(-36) ± √((-36)² - 4(11)(9))) / 2(11)
x = (36 ± √(1296 - 396)) / 22
x = (36 ± √900) / 22
x = (36 ± 30) / 22
x = (36 + 30) / 22 = 3
x = (36 - 30) / 22 = 3/11
x = 3 and x = 3/11.

given the following limit lim(x;y)!(0;0) xy x y , show that the function f (x; y) does not have a limit as (x; y) ! (0; 0).
To show that a function does not have a limit as (x, y) approaches (0, 0), we need to examine the limit along different paths .
How can we show that a function does not have a limit as (x, y) approaches (0, 0)?
To show that the function f(x, y) does not have a limit as (x; y) ! (0; 0), we need to examine the limit lim
(x;y)!(0;0) xy x y .
Convert the given limit into a more recognizable form. The given limit is
lim(x, y) -> (0, 0) (xy / (x + y)).
Analyze the limit along different paths. Let's examine the limit along two distinct paths - the
x-axis (y = 0)
and
the y-axis (x = 0).
For the x-axis (y = 0), the limit becomes
lim(x, 0) -> (0, 0) (x * 0 / (x + 0))
= lim(x, 0) -> (0, 0) (0) = 0.
For the y-axis (x = 0), the limit becomes
lim(0, y) -> (0, 0) (0 * y / (0 + y))
= lim(0, y) -> (0, 0) (0) = 0.
Compare the results of the two paths. Both limits along the x-axis and y-axis are equal to 0. However, this is not enough to conclude that the function f(x, y) has a limit as (x; y) ! (0; 0).
Examine another path, such as the line y = x. In this case, the limit becomes
lim(x, x) -> (0, 0) (x * x / (x + x))
= lim(x, x) -> (0, 0) (x^2 / 2x)
= lim(x, x) -> (0, 0) (x / 2)
= 0 / 2 = 0.
Consider another path, like
y = -x.
For this path, the limit becomes
lim(x, -x) -> (0, 0) (x * -x / (x - x))
which is undefined, since the denominator is zero.
Since we have found a path
(y = -x)
where the limit is undefined, we can conclude that the function f(x, y) does not have a limit as (x; y) ! (0; 0).

A statue casts a shadow that is 16 feet long. A nearby maple tree casts a shadow that is 10 feet long. If the statue is 20 feet tall, how tall is the maple tree, to the nearest tenth of a foot?
We can solve this problem by using proportions. 20/16 = x/10 => x = 12.5 Therefore, the height of the maple tree is approximately 12.5 feet, to the nearest tenth of a foot.
what is proportions ?
proportions are statements that two ratios or fractions are equal. A ratio is a comparison of two quantities, typically expressed as the quotient of one quantity divided by the other. For example, if we have 5 apples and 3 oranges, the ratio of apples to oranges is 5/3.
what is height ?
Height typically refers to the measurement of how tall or high something is, usually from its base to its top. In geometry, height is often used to refer to the perpendicular distance
In the given question ,
Let x be the height of the maple tree in feet. Then we have:
(height of statue) / (length of statue's shadow) = (height of maple tree) / (length of maple tree's shadow)
Substituting the given values, we get:
20/16 = x/10
on solving this equation, we can cross-multiply to get:
16x = 200 => x = 12.5
Therefore, the height of the maple tree is approximately 12.5 feet, to the nearest tenth of a foot.
