Answer:

Step-by-step explanation:

opposite sides of a parallelogram are equal . So,

NM = OL

2x + 5 = x + 10

2x - x = 10 - 5

x = 5

substitute the value of x

NM = 2x + 5

=2*5 + 5

=15

for NO also substitute 5 inplace of x

Answer:

m=-3/2

Step-by-step explanation:

To find slope we can use the formula y2-y1/x2-x1

Let's plug in our points

-1-2/1--1 which is -3/2

Our slope is -3/2

Answer:

m=-3/2

Step-by-step explanation:

In order to solve this problem, you must use the slope formula.

Slope formula:

\(\sf{\dfrac{Y_2-Y_1}{X_2-X_1}=\dfrac{RISE}{RUN} }\)

y2=(-1)

y1=2

x2=1

x1=(-1)

Rewrite the problem down.

Solve.

\(\sf{\dfrac{-1-2}{1-(-1)}=\dfrac{-1-2}{1+1}=\dfrac{-3}{2}=\boxed{\sf{-\dfrac{3}{2} }} }\)

Therefore, the slope is -3/2, which is our answer.

Answer:

$5,000,0000= total sales

Step-by-step explanation:

Giving the following information:

Commission rate= 4%

First, we need to calculate the total commission earned:

Commission= 350,000 - 125,000 - 25,000

Commission= $200,000

Now, using the following formulas, we can determine the total sales:

Commission= total sales*commission rate

200,000= total sales*0.04

200,000/0.04= total sales

$5,000,0000= total sales

Identifying Eigenvalues and Eigenvectors, A should be a n x n matrix. By resolving the det(λI−A)=0 problem, first determine the eigenvalues of A. Find the fundamental solutions to (λI−A)X=0 to determine the fundamental eigenvectors X≠0 for each.

In linear algebra, a nonzero vector is said to have an eigenvector, or characteristic vector, when a linear transformation is applied to it; this characteristic vector only changes by a scalar amount. The scaling factor for the eigenvector is known as the associated eigenvalue, frequently represented by the symbol. Linear transformations are made intelligible by the usage of eigenvectors. Eigenvectors can be thought of as a non-directional stretching or compressing of an X-Y line chart. In mathematics, eigenvalues are regarded as the factor by which a transformation is stretched, whereas eigenvectors are the real non-zero eigenvalues that point in the direction stretched by the transformation. The direction of the transformation is negative if the eigenvalue is negative.

The average speed for the first part of the trip is 60 miles.

Given:

1st leg DATA:

distance = 120 miles ;

rate = x mph ;

time = d/r = 120/x hrs

2nd leg DATA:

distance = 220 miles ;

rate = x-5 mph ;

time = 220/(x-5) hrs

hence the equation we frame is:

Equation:

120/x + 220/(x-5) = 6

120(x-5) + 220x = 6x(x-5)

120x - 600 + 220x = 6x² - 30x

-6x² + 340x + 30x - 600 =0

-6x² + 370x - 600 = 0

-3x² - 185x + 300 = 0

(3x-5)(x-60)

3x = 5 or x-60=0

x = 5/3 or x = 60

hence x-5 = 60-5

= 55 miles per hour.

Hence we get the answer as 60 miles.

If income growth is higher in the United States, the dollar would appreciate and the British pound would depreciate.

If inflation is higher in Britain, the dollar would appreciate and the British pound would depreciate.

If real interest rate is higher in the United States, the dollar would appreciate and the British pound would depreciate.

Exchange rate is the relative value of two or more currencies. When a currency appreciates, it means that one unit of that currency is buying more units of another currency. When a currency depreciates, it means that one unit of that currency is buying less units of another currency.

If income growth is higher in the United States, it indicates that the economy is growing. As a result the dollar would appreciate in value.

Inflation is when there is a persistent rise in the general price levels. Inflation decreases the purchasing power of currency. Thus, if inflation is higher in Britain, the British pound would depreciate.

If real interest rate is higher in the United States, more investors would want to invest in the US. This would increase the demand for the dollar. As a result, the US dollar would appreciate in value.

a) is the graph of inverse sine function.

The inverse of the sine function, also known as the arcsine function, returns the angle's value when the sine function's opposite side and hypotenuse ratio are equal. It produces the angle's value.

When the opposing side and hypotenuse of a right triangle are known, the angles can be determined using the inverse sine function. That is, angle = sin-1. The inverse sine function, which is represented as sin-1 or arcsine, is one of the inverse trigonometric functions that calculates the inverse of the sine function. Each restricted domain inverse of a trigonometric function, such as cosine, tangent, cosecant, or cotangent, exists. The trigonometric ratios from the right-angle triangle are utilized to compute the angles using the inverse function formulas.

a) The median would be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean.

b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers.

a) The median is expected to be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean. The mean is calculated by adding all the values together and dividing by the number of values, and if there are any values that are much lower or higher than the rest, this will affect the mean significantly. The median, however, is the midpoint of the values, so outliers have less of an influence on it.

b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers. The median is the midpoint of the values, which means that if there are any values that are much lower or higher than the rest, it will not affect the median as much as it does the mean. This makes the median more accurate in representing the life expectancy of countries, as it is not skewed by outliers. Furthermore, the median is generally more reliable when dealing with skewed distributions, which is often the case with life expectancy data.

Step-by-step explanation:

Finding an equation of a tangent line to that function requires that we find the derivative of the function at that point. Since this is an absolute value function with its cusp at (2, 5), the function is not differentiable here.

The missing word is "modulus". The statement should read: Twelve is congruent to 60 (modulus 8) because both 12 and 60 have 4 as a remainder when divided by 8.

The modulus function, also known as the modulo operation or mod function, is a mathematical operation that returns the remainder when one integer is divided by another. The modulo operation is a quick and efficient way to find the remainder of a division. For example, if we want to know the remainder when 23 is divided by 5, we can simply compute 23 % 5, which equals 3. The symbol "%" is often used to represent the modulo operation in computer programming, while "mod" is used in mathematical notation to indicate congruence. In either case, the statement means that 12 and 60 leave the same remainder when divided by 8.

Based on the information provided, a correlation coefficient of r = .52 and a reported p < .05 indicates that there is a statistically significant positive relationship between the two variables being studied.

The p-value of less than .05 suggests that the observed correlation is unlikely to be due to chance, and the positive r- value of .52 shows a moderate strength in the relationship. The p-value in this context indicates the statistical significance of the correlation coefficient. When it is stated that "p < .05," it means that the p-value associated with the correlation coefficient is less than 0.05. This is typically used as a threshold to determine statistical significance.

In statistical hypothesis testing, the p-value represents the probability of obtaining a correlation coefficient as extreme as the observed value (or more extreme) if there were no true correlation in the population. Therefore, a p-value less than 0.05 suggests that the observed correlation coefficient is statistically significant.

In other words, the p-value being less than 0.05 indicates that the correlation observed in the study is unlikely to have occurred by chance alone. It provides evidence to support the existence of a relationship between the variables being studied.

Answer:

This is not possible. Perpendicular lines are opposite but there are no opposites of 0

Step-by-step explanation:

The function has an average rate of change f is 1/2 over the interval

The possible graph that completes the question is added as an attachment

The interval is given as

-3 ≤ x ≤ 9

This can be rewritten as

x = -3 to x = 9

This can also be represented as

(a, b) = [-3, 9]

From the attached graph, we have

f(-3) = -1.5

Also, we have

f(9) = 0.5

The estimate (to one decimal place) of the average rate of change f is calculated as

Rate = [f(b) - f(a)]/[b - a]

This gives

Rate = [f(9) - f(-3)]/[9 + 3]

So, we have

Rate = [0.5 + 1.5]/[9 + 3]

Evaluate

Rate = 2/12

Simplify

Rate  = 1/6

Hence, the average rate of change f is 1/6
