A football team gained an average of 3.4 yards in 4 plays. How many total yards did the team make in 4 plays?

The standard error of the mean is approximately $115.63.

The standard error of the mean (SEM) measures the variability or uncertainty in the sample mean compared to the true population mean. It indicates the average amount that the sample mean differs from the population mean.

To calculate the standard error of the mean, we use the formula:

SEM = σ / √n

Where:

SEM: Standard error of the mean

σ: Population standard deviation

n: Sample size

Given information:

Population standard deviation (σ) = $1,850.00

Sample size (n) = 256

Plugging in the values into the formula, we can calculate the standard error of the mean:

SEM = 1850 / √256

To simplify the calculation, let's first calculate the square root of 256:

√256 = 16

Now, we can divide the population standard deviation by the square root of the sample size:

SEM = 1850 / 16

Simplifying the fraction, we have:

SEM = 115.625

Therefore, the standard error of the mean is approximately $115.63.

The area of the rectangle ABCD is approximately 29.15 square units.

To find the area of the rectangle ABCD, we can use the formula for the area of a rectangle, which is given by the product of its length and width.

Let's first find the length and width of the rectangle using the coordinates of its vertices.

Length AB = distance between points A and B

= √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(1 - (-4))² + (4 - 4)²]

= √[5² + 0²]

= √25

= 5

Width BC = distance between points B and C

= √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(-4 - 1)² + (1 - 4)²]

= √[(-5)² + (-3)²]

= √[25 + 9]

= √34

Now that we have the length and width, we can calculate the area of the rectangle.

Area = Length × Width

= 5 × √34

≈ 5 × 5.83

≈ 29.15 square units

Therefore, the area of the rectangle ABCD is approximately 29.15 square units.

The correct answer is .a. 68%

In a normal distribution, approximately 68% of the area under the curve falls within one standard deviation of the mean. This is known as the empirical rule or the 68-95-99.7 rule. Specifically, about 34% of the area lies within one standard deviation below the mean, and about 34% lies within one standard deviation above the mean. Therefore, the total area within one standard deviation is approximately 68% of the total area under the curve.

Option b (100%) is incorrect because the entire area under the curve is not within one standard deviation. Option c (95%) is incorrect because 95% of the area under the curve falls within two standard deviations, not just within one standard deviation. Option d (It depends on the values of the mean and standard deviation) is also incorrect because the percentage within one standard deviation is approximately 68% regardless of the specific values of the mean and standard deviation, as long as the distribution is approximately normal.

The original expression is equivalent to -1.63.

What is an expression?

In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, -, ×, ÷, and parentheses) that represents a mathematical quantity or relationship. Expressions are simple or complex, and they can involve one or more variables.

We can simplify the expression 0.87 – 4.5 – [5.8 + (-7.8)] by following the order of operations (PEMDAS) and performing the operations inside the brackets first:

0.87 - 4.5 - [5.8 + (-7.8)] = 0.87 - 4.5 - [-2.0]

Next, we can simplify the expression inside the second set of brackets by multiplying -1 by each term inside:

0.87 - 4.5 - [-2.0] = 0.87 - 4.5 + 2.0

Finally, we can combine like terms by adding -4.5 and 2.0:

0.87 - 4.5 + 2.0 = -1.63

Therefore, the original expression is equivalent to -1.63.

Answer:

use the app gauth-math. (the value of n is 3.)!!!!!!!!!!

Step-by-step explanation: it works for these and other equations!

The value of c that makes the equation true is c = 64, when x = 6 and y = 3.

To find the value of c that makes the equation true, we can start by simplifying both sides of the equation using exponent rules and canceling out common factors.

First, we can simplify 3√(x^3) to x√x, and 3√y to y√y, giving us:

x√x/cy^4 = x/4y(y√y)

Next, we can simplify x/4y to 1/(4√y), giving us:

x√x/cy^4 = 1/(4√y)(y√y)

We can cancel out the common factor of √y on both sides:

x√x/cy^4 = 1/(4)

Multiplying both sides by 4cy^4 gives us:

4x√x = cy^4

Now we can solve for c by isolating it on one side of the equation:

c = 4x√x/y^4

We can substitute in the values of x and y given in the problem statement (x>0 and y>0) and simplify:

c = 4x√x/y^4 = 4(x^(3/2))/y^4

c = 4(27)/81 = 4/3 = 1.33 for x = 3 and y = 3

c = 4(64)/81 = 256/81 = 3.16 for x = 4 and y = 3

c = 4(125)/81 = 500/81 = 6.17 for x = 5 and y = 3

c = 4(216)/81 = 64 for x = 6 and y = 3

If Amir is not courageous, then he will not join the indian army.

The total number of different 9-letter permutations which can be formed from 7 identical H's and 2 identical T's are 36,288.

In order to find the number of different 9-letter permutations which can be formed from 7 identical H's and 2 identical T's, we need to apply the formula for permutations with repetition, which is given as

P(n1, n2, ..., nk) = n!/(n1!n2!...nk!), where n1, n2, ..., nk are the number of times

each of the k distinct objects are repeated.

Here, we have n = 9, n1 = 7 and n2 = 2, since we have 7 H's and 2 T's. Substituting these values in the formula, we get:

P(7, 2) = 9!/(7!2!) = 36,288

Therefore, there are 36,288 different 9-letter permutations that can be formed from 7 identical H's and 2 identical T's.

:Thus, the total number of different 9-letter permutations which can be formed from 7 identical H's and 2 identical T's are 36,288.

Answer:

Problem 2) : the gradient is "-2", and the y-intercept is "3"

Problem 3)

A is  \(y=2x+2\)

B is \(y=x+2\)  

Step-by-step explanation:

Problem 2)

In the line given by the equation:   \(y=-2x+3\)

the "gradient" (also known as "slope") is the numerical coefficient that multiplies the variable "x". So in this case the gradient is "-2"

the y-intercept is the numerical term "+3" because that is the y-value result of evaluating the expression for x = 0

\(y=-2x+3\\y=-2\,(0)+3\\y=3\)

Problem 3)

Consider the two lines :

\(y=x+2\)  and  \(y=2x+2\)

notice that both have the same y-intercept (that is the numerical term "2" at the end of both expressions. That means that both lines cross the y-axis at the point y=2.

Now notice that the gradient of one of them is "1"  (for \(y=x+2\) ) that is the coefficient that multiplies the variable "x". While for the other line ( \(y=2x+2\))  the gradient is "2" and therefore steeper than the previous one.

Then, the line identified as "A" which is the one with steeper gradient, corresponds to the equation   \(y=2x+2\), and the line identified with "B" is the one with smaller gradient  \(y=x+2\)  .

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The percent of students pursuing economics is 29%.

And, the number of students pursuing economics is 2688.

Suppose the total number of students are x.

Then, the following equation can be written for the given case,

29% of x = 2668

=> 29/100 × x = 2668

=> x = 2668 × 100/29

Since these intervals overlap, one cannot say with certainty that more people clearly support Bugs Bunny over Baby Shark in the population based on the poll results. Further research or a larger sample size would be needed to determine the true support for each candidate.

In a heated election, people will vote for their all-time favorite cartoon. Before the election, a poll was taken to see the results and it showed that 34% of the people said they will vote for Bugs Bunny, and 26% said they will vote for Baby Shark.
