The football team has a total of jerseys 20 There are 14 ​medium-sized jerseys. What percent of the jerseys are​ medium-sized jerseys?

Answer:

y ≈ 5.2

Step-by-step explanation:

∠ F = 180° - (42 + 48)° ← sum of angles in a triangle

∠ F = 180° - 90° = 90°

Thus Δ DEF is right at F

Using the sine ratio in the right triangle

sin48° = \(\frac{opposite}{hypotenuse}\) = \(\frac{DF}{DE}\) = \(\frac{y}{7}\) ( multiply both sides by 7 )

7 × sin48° = y , then

y ≈ 5.2 ( to the nearest tenth )

Answer:

no because 1+2<7. To form a triangle any two lengths have to be greater than third one

A function that satisfies the condition of having its square plus the square of its derivative equal to 1 is given by f(x) = sin(x).

The function f(x) = sin(x) has the property that its square, sin^2(x), is equal to 1 when added to the square of its derivative, \($\frac{d}{dx}\sin(x))^2 = \cos^2(x)$\).

This can be seen by directly evaluating the expression: \(sin^{2}(x) + cos^{2}(x) = 1\), which is a fundamental identity in trigonometry.

The sine function is periodic with a period of 2π, and its derivative, cosine function, also has the same period. This means that for any x, the function sin(x) and its derivative cos(x) will satisfy the given condition.

Geometrically, the sine function represents the y-coordinate of a point on the unit circle as the corresponding angle is varied. Its derivative, the cosine function, represents the rate of change of this y-coordinate with respect to the angle. The squares of the sine and cosine functions add up to 1, which is the square of the radius of the unit circle. This property is fundamental in trigonometry.

The compound formed between Ag and Se is Ag₂Se.

To determine the formula of the compound, we need to consider the charges of the individual ions. Ag is the symbol for silver, which commonly forms a 1+ cation (Ag⁺). Se is the symbol for selenium, which commonly forms a 2- anion (Se²⁻).

To combine the two ions in a neutral compound, we need to find the ratio that balances their charges. Since Ag has a 1+ charge and Se has a 2- charge, we need two Ag⁺ ions to balance the charge of one Se²⁻ ion.

Therefore, the formula for the compound is Ag₂Se.

Step-by-step explanation:

The expressions for (f + g)(x), (f - g)(x), fg(x), and f/g(x) are:

(f + g)(x) = 8x + 4

(f - g)(x) = 2x² + 8x - 4

fg(x) = -x⁴ - 4x² + 32x

f/g(x) = (x² + 8x) / (4 - x²), x ≠ 2, x ≠ -2

To find (f + g)(x), we need to add the functions f(x) and g(x):

1. (f + g)(x) = f(x) + g(x)

           = (x² + 8x) + (4 - x²)

           = x² + 8x + 4 - x²

           = 8x + 4

So, (f + g)(x) = 8x + 4.

To find (f - g)(x), we need to subtract the function g(x) from f(x):

2. (f - g)(x) = f(x) - g(x)

           = (x² + 8x) - (4 - x²)

           = x² + 8x - 4 + x²

           = 2x² + 8x - 4

So, (f - g)(x) = 2x² + 8x - 4.

3. To find fg(x), we need to multiply the functions f(x) and g(x):

fg(x) = f(x). g(x)

     = (x² + 8x) * (4 - x²)

     = 4x² - x⁴ + 32x - 8x²

     = -x⁴ - 4x² + 32x

So, fg(x) = -x⁴ - 4x² + 32x.

4.To find f/g(x), we need to divide the function f(x) by g(x):

f/g(x) = f(x) / g(x)

      = (x² + 8x) / (4 - x²)

We solve the equation g(x) = 0:

4 - x² = 0

x² = 4

x = ±2

So, x = 2 and x = -2 are the values for which g(x) equals zero, and thus we cannot divide by g(x) at those points.

Therefore, we can define f/g(x) as:

f/g(x) = (x² + 8x) / (4 - x²), x ≠ 2, x ≠ -2

Answer:

65

Step-by-step explanation:

115 + x = 180

x = 180 - 115

x = 65

Answer:

65°

Step-by-step explanation:

A right-angle equals 90°. Two right angles would be a line like shown in the picture.

So, 90 + 90 = 180.

Since we know the whole amount of the 2 angles combined is 180, all we have to do is subtract 115 from 180 to find the missing value.

180 - 115 = 65

Therefore, 65° equals x.

The reflection of the graph of g(x) = log x about the x-axis is the graph of f(x) = log x.

Let's first review the graph of g(x) = log x to see how this works. The collection of all points (x, y) in the coordinate plane where y = log x is known as the graph of g(x).

The point (1, 0) is where the graph of g(x) passes. It is an ascending curve with a positive infinity as it approaches positive infinity as x approaches infinity.

Let's now examine the f(x) = log x graph. The collection of all (x, y) coordinate plane points where y = log x exists is the graph of f(x).

The logarithm property that states: log a (1/b) = log a to determine the relationship between the graphs of f(x) and g(x) (b) To rewrite f(x) as follows using this property: f(x) = log x = log (1/x)

This demonstrates that the negative logarithm of x, or the logarithm of 1/x, is what f(x) is. As a result, the graph of f(x) and g(x) are identical, with the f(x) graph being reflected about the x-axis.

The graph of f(x) = log x is a mirror of the graph of g(x) = log x about the x-axis, which is the answer to the question.

The probability that the gambler has strictly more than $32 after playing the game five times is 68.75%.

Probability is a branch of mathematics that deals with the likelihood of an event occurring. In this problem, we are dealing with a gambler who is playing a game with equal probability of doubling or reducing their stake to half.

The gambler's initial stake is $32. Let us consider the possible outcomes after one play of the game. The stake can either double to $64 or reduce to $16, each with equal probability. If the stake doubles, the gambler has more than their initial stake. If the stake is reduced to half, the gambler has less than their initial stake.

Now, let us consider the possible outcomes after two plays of the game. There are four possible outcomes:

(1) the stake doubles twice and the gambler has

=> $64 * 2 = $128,

(2) the stake doubles then reduces to half and the gambler has

=> $32 * 2 * 0.5 = $32,

(3) the stake reduces to half then doubles and the gambler has

=> $32 * 0.5 * 2 = $32,

(4) the stake reduces to half twice and the gambler has

=> $32 * 0.5 * 0.5 = $8.

We can represent these outcomes using a tree diagram. Each branch represents a possible outcome, and the probability of that outcome is written next to the branch.

After five plays of the game, there are 32 possible outcomes.

We can calculate the probability of the gambler having more than their initial stake by adding up the probabilities of all the outcomes where the gambler has more than $32. This turns out to be 0.6875 or 68.75%.

When the area under the standard normal curve from 0 to z is 0.3508 and z is positive, the value of z is approximately 1.04 which can be found by using the z-table.

To find the value of z when the area under the standard normal curve from 0 to z is 0.3508 and z is positive, you can use the z-table or a standard normal distribution table.

1. Since the area from 0 to z is 0.3508, you need to find the total area to the left of z, which is the sum of the area from the left tail to the mean (0.5) and the area from the mean to z (0.3508). So, the total area to the left of z = 0.5 + 0.3508 = 0.8508.

2. Look up the closest value to 0.8508 in the standard normal distribution table (also known as the z-table), which shows the cumulative probability (area) for a given z-score.

3. Locate the row and column that corresponds to the value closest to 0.8508. In this case, the closest value is 0.8508 itself, located at the intersection of the row with 1.0 and the column with 0.04.

4. Combine the row and column values to find the corresponding z-score. In this case, the z-score is 1.04.

The test results fail to reject the null hypothesis, indicating that recent winners do not appear to be significantly different from those in the 1920s and 1930s.

To determine if recent Miss America winners have a significantly different BMI compared to winners from the 1920s and 1930s, a one-sample t-test can be conducted. Using the given sample, the sample mean BMI is calculated to be 18.5.

The null hypothesis is that the population mean BMI of recent winners is equal to 19.2. The alternative hypothesis is that the population mean BMI of recent winners is different from 19.2.

Assuming a significance level of 0.05 and using a two-tailed test, the calculated t-value is -2.08 and the corresponding p-value is 0.057.

Since the p-value is greater than the significance level, we fail to reject the null hypothesis. This suggests that there is not enough evidence to conclude that recent Miss America winners have significantly different BMI compared to winners from the 1920s and 1930s.

Using the Normal Z-distribution and the values from the Z-table, We can calculate that 12.5% can be expected to score between 70 and 90 according to the value of mean and standard deviation provided.

As opposed to methods for gathering statistical data, mathematical statistics is the application of probability theory, a subfield of mathematics, to statistics. Because it integrates math ideas to create an analysis of a data set that may be used to comprehend a relationship in the data, statistics has earned a reputation for being an extremely challenging course, especially when studied in college.

A unique type of normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution, or z-distribution. By transforming the values of any normal distribution into z scores, it is possible to standardize it. Z scores provide the number of standard deviations from the mean that each value falls within.

mean =100

standard deviation =60
