The statement made by Diego is correct.

In order to determine the number of groups of 5/6 that are in 1, 1 would be divided by 5/6.

1 ÷ 5/6

= 1 x 6/5 = 6/5

6/5 is called an improper fraction because the numerator is greater than the denominator.

6/5 can also be rewritten as a mixed fraction. If it is rewritten as a mixed fraction, it becomes 1 1/5.

The value of the angle is 120°.

The corresponding angle of a given angle refers to the angle in a congruent position in another figure. For example, if two lines intersect, the angle formed at one vertex of the intersection is called a vertex angle. The corresponding angle in the other figure is the angle in a congruent position, meaning that it has the same measure.

We are given two lines to be parallel

Hence the angle adjacent to x is 40°

Now Sum of All three angle is 180° (Angles in linear pair)

Hence we have

40 + x + 20 = 180°

x = 120°

Hence the measure of angle x is 120°

The side RT of the triangle is 13 m.

Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.

The sine law is a mathematical formula used in trigonometry to relate the sides and angles of a triangle. The sine law states that:

a/sin(A) = b/sin(B) = c/sin(C)

where:

a, b, and c are the lengths of the sides of the triangle

A, B, and C are the angles opposite those sides

Using sine law:

RT/sin 34° = ST/sin 109°

RT/sin 34° = 22/sin 109°

RT = (22 * sin 34°)/(sin 109°)

RT = 13 m

Step-by-step explanation:

f(x)=-3x²-4x+15

if (-3,-2) is substitute

x=-3 x=-2 is substitute in above given equation we get real zero.

The federal loan at 2.8% is approximately 11000, and the private bank loan at 4.8 percent is around 39000 (which is 50000 - 11000).

Let's use f and p to denote the amounts of Josie's federal and private bank loans, respectively.

We know that the total amount of loans is 50000, so:

f + p = 50000

We also know that the interest on federal loans at 2.8% and the interest on private bank loans at 4.8% add up to 1600 per year. The interest on the federal loans is 0.028f and the interest on the private bank loans is 0.048p, so:

0.028f + 0.048p = 1600

We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for p:

p = 50000 - f

Substituting this into the second equation, we get:

[tex]0.028f + 0.048(50000 - f) = 1600[/tex]

Simplifying and solving for [tex]f[/tex], we get:

[tex]f = \frac{1600 - 0.048 \cdot 50000}{0.02} \approx 11000[/tex]

Therefore, the federal loan at 2.8% is approximately 11000, and the private bank loan at 4.8% is approximately 39000 (which is 50000 - 11000).

Answer:

a. The probability that a married couple watches the show can be calculated by multiplying the probabilities that each spouse watches the show:

P(Married couple watches the show) = P(Husband watches the show) * P(Wife watches the show) = 0.4 * 0.5 = 0.2

Step-by-step explanation:

b. The probability that a wife watches the show, given that her husband does, can be calculated using Bayes' theorem:

P(Wife watches the show | Husband watches the show) = P(Husband watches the show | Wife watches the show) * P(Wife watches the show) / P(Husband watches the show)

P(Wife watches the show | Husband watches the show) = 0.7 * 0.5 / 0.4 = 0.875

c. The probability that at least one member of a married couple will watch the show can be calculated as the sum of the probabilities that either the husband or the wife watches the show:

P(At least one member of a married couple watches the show) = P(Husband watches the show) + P(Wife watches the show) - P(Married couple watches the show) = 0.4 + 0.5 - 0.2 = 0.7

The input is 8, the output of the function f(x) would be -5.

What is the function?

Function is a relationship or expression involving one or more variables.  It has a set of input and outputs.

Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences. The modern definition of function was first given in 1837 by the German mathematician Peter Dirichlet

To find the output of the function f(x) when x is 8, we substitute x = 8 into the function and simplify:

f(x) = 8/x - 6

f(8) = 8/8 - 6

f(8) = 1 - 6

f(8) = -5

Hence, if the input is 8, the output of the function f(x) would be -5.

Answer: a) Mean and standard deviation of the sampling distribution:

The mean of the sampling distribution, also known as the expected value or the population mean, is equal to the proportion of U.S. residents who receive a jury summons each year, which is 15%. So, the mean of the sampling distribution is:

µ = 0.15

The standard deviation of the sampling distribution, also known as the standard error, can be calculated using the formula:

σ = √(p(1 - p) / n)

where p is the population proportion of U.S. residents who receive a jury summons each year (0.15), and n is the sample size (500).

σ = √(0.15 * (1 - 0.15) / 500)

σ ≈ 0.03

So, the standard deviation of the sampling distribution is approximately equal to 0.03.

b) Interpretation of the standard deviation:

The standard deviation measures the spread of the sampling distribution, or how much the sample proportions deviate from the population proportion. A smaller standard deviation indicates that the sample proportions are more likely to be close to the population proportion, while a larger standard deviation indicates that the sample proportions are more likely to be further from the population proportion.

In this case, the standard deviation of 0.03 indicates that the sample proportions are expected to be within 0.03 of the population proportion (0.15) about 68% of the time.

c) Justification for the approximate normality of the sampling distribution:

According to the central limit theorem, the distribution of the sample proportions will be approximately normal as long as the sample size is large enough. In this case, with a sample size of 500, we can assume that the sampling distribution is approximately normal.

Answer:

The solution to the equation 20 = m ÷ -5 is m = -100

To see this, we can multiply both sides of the equation by -5 to isolate the variable m:

20 × -5 = m ÷ -5 × -5

Expanding the right side of the equation:

20 × -5 = m × 1

Combining like terms:

-100 = m

And the solution is:

m = -100

Verification:

To verify the solution, we can plug in the value of m back into the original equation and see if it is true:

20 = -100 ÷ -5

Expanding -100 ÷ -5:

20 = 20

Since 20 = 20 is a true statement, we have verified that the solution m = -100 is correct.

The solution set for the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex] is (-4, -3) ∪ (-3, ∞).

What is inequality?

An inequality is a mathematical statement that describes a relationship between two values or expressions, where one is greater than, less than, or not equal to the other.

To solve the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex], we can use the concept of interval notation and test each interval to see if it satisfies the inequality. Here are the steps:

Find the critical points of the expression, which are the values that make the expression equal to zero. In this case, the critical points are -5, -4, and -3.

Use these critical points to divide the number line into four intervals: (-∞, -5), (-5, -4), (-4, -3), and (-3, ∞).

Test a value in each interval to see if the inequality is true or false. We can use the sign of the expression to determine this:

For x < -5, all three factors are negative, so the product is negative. Therefore, this interval does not satisfy the inequality.

For -5 < x < -4, the first factor is positive and the other two factors are negative. The product is therefore negative. This interval does not satisfy the inequality.

For -4 < x < -3, the first and third factors are positive and the second factor is negative. The product is therefore positive. This interval satisfies the inequality.

For x > -3, all three factors are positive, so the product is positive. Therefore, this interval satisfies the inequality.

Write the solution set using interval notation. We have found that the solution set is (-4, -3) union ( -3, ∞).

Therefore, the solution set for the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex] is (-4, -3) ∪ (-3, ∞).

The proof of congruence by SAS, then 2 corresponding sides and the corresponding included angles of both triangles are equal.

Angles who are of same measurement are called congruent.

Suppose that two angles ∠A and ∠B are of same measure, then

[tex]m\angle A = m\angle B[/tex]is the notation to say that they are of same measurement, where the small m shows that its the measurement of the angles they're preceding.

The SAS postulate , Two sides and the included angle of one triangle are identical to the corresponding two sides and the included angle of another triangle.

In the triangle, the angles mCAD and mACB are congruent.

m∠CAD ≅ m∠ACB

Since m∠CAD and m∠ACB are congruent, AD and BC must also be congruent.

As a result, the SAS Congruence postulate is proven.

We can simplify the expression as follows:

tan(x) + cot(x)/sec(x) = tan(x) + 1/tan(x) / 1/cos(x) = tan(x) + cos(x) / tan(x) * cos(x) = tan(x) + cos^2(x) / tan(x)

Using the identity: tan(x)^2 + 1 = sec^2(x), we can simplify further:

tan(x) + cos^2(x) / tan(x) = tan(x) + cos^2(x) / (sqrt(sec^2(x) - 1)) = tan(x) + cos^2(x) / sqrt(tan^2(x) + 1 - 1) = tan(x) + cos^2(x) / sqrt(tan^2(x))

Using the identity sin^2(x) + cos^2(x) = 1, we can simplify further:

[tex]tan(x) + cos^2(x) / \sqrt(tan^2(x)) = tan(x) + (1 - sin^2(x)) / \sqrt(tan^2(x)) = tan(x) + \sqrt(1 - sin^2(x)) / \sqrt(tan^2(x)) = sin(x) * (1 / \sqrt(1 - sin^2(x)) + \sqrt(tan^2(x)) / \sqrt(1 - sin^2(x)))[/tex]
