Step-by-step explanation:

Answer:

m<FED=60, m<DEN=120

Step-by-step explanation:

m<FED=60

This is because <GEN and <FED are vertical angles.

Vertical angles are always congruent.

Vertical angles are formed by a pair of intersecting lines, and are the angles directly across from one another.

m<DEN=120

This is because <DEN and <GEN are supplementary.

Supplementary angles add up to 180 degrees.

We know this because a straight line is always 180 degrees.

So:

m<DEN+m<GEN=180

m<DEN+60=180

m<DEN=120

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Answer:

Answer:

(1,0)

Step-by-step explanation:

Hi there!

We're given the equation of the line as 2y+3x=3, and we want to find the x intercept of the line.

The x intercept is the coordinate point at which the line passes through the x axis. Therefore, the value of y at the x intercept will be 0.

So we can substitute 0 as y in 2y+3x=3; we'll only have x left if we do this to solve for the x intercept.

2(0)+3x=3

multiply

3x=3

divide both sides by 3

x=1

so the x intercept is 1; as a point it's (1,0)

Statistical power is a measure of the ability to reject the null hypothesis when it is false. It represents the probability of correctly identifying a true effect or relationship in a statistical hypothesis test.

A high statistical power indicates a greater likelihood of detecting a significant result if the null hypothesis is indeed incorrect. The power of a statistical test depends on several factors, including the sample size, the effect size (the magnitude of the true effect or difference), the chosen significance level (often denoted as α), and the variability or noise in the data. Increasing the sample size or effect size generally increases the statistical power, while a lower significance level or higher variability decreases it.

Power analysis is commonly used to determine an appropriate sample size for a study, ensuring that it is adequately powered to detect the desired effect. A higher power is desirable as it reduces the chances of a Type II error (failing to reject the null hypothesis when it is false) and increases the chances of correctly detecting real effects or relationships.

Answer:

5 years

Step-by-step explanation:

A = $4,635.00

I = A - P = $135.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 0.6%/100 = 0.006 per year.

Solving our equation:

A = 4500(1 + (0.006 × 5)) = 4635

A = $4,635.00

The total amount accrued, principal plus interest, from simple interest on a principal of $4,500.00 at a rate of 0.6% per year for 5 years is $4,635.00.

The probability that the project will take 224 days or longer is 0.1587.

This is a question on the normal probability distribution.

To expiate this, standardize the 95 days.

The standardized score is calculated by subtracting the value from the mean and dividing it by the standard deviation.

z = (x - xbar) ÷ σ

x = 224 days

xbar = mean = 214 days

σ = standard deviation = √(variance) = √100 = 10

z = (224 - 214) ÷ 10 = 1

To calculate the probability that the project will be finished in 95 days or less, P(x ≥ 224) = P(z ≥ (1))

For these probabilities, use data from the normal probability table.

P(x ≥ 224) = P(z ≥ (1)) = 1 - 0.8413 = 0.1587

The height of the prism \(\approx 2.9\)

The whole volume of the prism is

\(\text{Volume} = \text{Area of base}\times \text{Height}\)

Here, the volume is 38 cu. in.

From the question, the area and the height are related as follows;

\(\text{Height} = \text{Area} - 10 \implies \text{Height + 10} =\text{Area}\)

Substituting this into the formula for the volume, we get

\(\text{Volume}=(\text{Height} +10)\times \text{Height}=38\\\\\text{Height}^2 + 10\times\text{Height}=38\\\\\text{Height}^2 + 10\times\text{Height}-38=0\)

If the above quadratic equation is solved for the height, we get

\(\text{Height}\approx 2.9\)

Answer:

Given:

Sample size, n = 6965

Sample proportion p' = \( \frac{1330}{6965} = 0.19 \)

Let's claim that the return rate is less than​ 20%, ie, P = 0.2

Significance level = 0.01

The null and alternative hypotheses:

H0 : P = 0.2

H1 : P < 0.2

Option A is correct

_____________________________

For the test statistic, Z, let's use the formula:

\( Z = \frac{p'- P}{\sqrt{\frac{P(1-P)}{n}}} \)

\( = \frac{0.19 - 0.2}{\sqrt{\frac{0.2(1 - 0.2)}{6965}}} = -1.887 \)

Z = -1.887 ≈ -1.89

___________________________

The p-value.

This is a left tailed test.

Using z table,

P-value = P(Z ≤ -1.89) = 0.029

The pvalue is 0.029

Decision:

Because the pvalue, 0.029 is greater than level of significance, 0.01, we fail to reject null hypothesis, H0.

Conclusion:

There is not enough sufficient evidence to conclude that the return rate is less than 20%

Step-by-step explanation:

Answer:

For the equation 2 = 2, it is not possible to make this equation false by using the Properties of Equality. This is because the equation is already true, and any manipulation of the equation using the Properties of Equality would not change this fact. Therefore, this equation has one solution.

For the equation 2 ≠ 3, it is not possible to make both sides equal by using the Properties of Equality. This is because the equation is stating that the two sides are not equal, and any manipulation of the equation using the Properties of Equality would not change this fact. Therefore, this equation has no solutions.

Step-by-step explanation:

First of all you need to find out the surface of the front.

So you need to do 29cm + 29cm = 58cm.

You then have to do 22cm + 22cm = 44cm

So if you add those two numbers up you will get the front surface which is 102cm.

Next, you need to find the surface of the side.

So you need to do 20cm + 21cm = 41cm

After that, you need to find the back surface.

So you need to add 22cm +22cm = 44cm

Then you have to do 21cm + 21cm = 42cm

Add those two together to get 86cm

Then, you need to do the bottom of the shape.

So you need to add 22cm + 22cm (again) = 44cm

You then need to do 20cm + 20cm = 40cm

Add those together to get 84cm

Finally, you need to add 84cm + 86cm + 102cm + 41cm = 313cm

So your answer is:

Confounding variables are any other variable that also has an effect on your dependent variable.

What is a confounding variable?

A confounding variable, also called a confounder or confounding factor, is a third variable in a study examining a potential cause-and-effect relationship.

A confounding variable is related to both the supposed cause and the supposed effect of the study. It can be difficult to separate the true effect of the independent variable from the effect of the confounding variable.

In your research design, it's important to identify potential confounding variables and plan how you will reduce their impact.

For example, if you are researching whether drinking both sample lead to taste test, then drinking both sample  is your independent variable and taste test is your dependent variable. Confounding variables are any other variable that also has an effect on your dependent variable.

Vector subtraction is done by arranging head to tail.

Vector subtraction is the process of finding the vector that results from taking away one vector from another. To perform vector subtraction, we arrange the vectors head to tail, with the tail of one vector touching the head of the other vector. We then draw a new vector from the tail of the first vector to the head of the second vector. The resulting vector is the difference between the two vectors. This can be mathematically represented as:

a - b = a + (-b)

where "a" and "b" are vectors, and (-b) is the additive inverse of b, which is the vector with the same magnitude as b but opposite in direction.
