Step-by-step explanation:

The unknown side length will be 14 cm if the longest side of an isosceles obtuse triangle measures 20 centimeters option third 14 is correct.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

The question is incomplete.

The complete question is:

The longest side of an isosceles obtuse triangle measures 20 centimeters. The other two side lengths are congruent but unknown. What is the greatest possible whole-number value of the congruent side lengths?

9 cm

10 cm

14 cm

15 cm

We have:

The longest side of an isosceles obtuse triangle measures 20 centimeters.

Let's assume the unknown side length is x:

In the isosceles obtuse triangle, two sides are congruent.

As we know the sum of the two sides in a triangle is greater than the third side length:

x + x > 20

2x > 20

x > 10

a² + b² < c²

14 will satisfy the above two inequaility.

Thus, the unknown side length will be 14 cm if the longest side of an isosceles obtuse triangle measures 20 centimeters option third 14 is correct.

Step-by-step explanation:

The probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.

Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes.

Probability is a measure of how likely an event is going to happen.

Given is to find the probability that a point randomly chosen in the large triangle is also in Region A.

We can find the area of region A as -

Area{A} = A{Rectangle} + A{Right triangle}

Area{A} = (Length x Breadth) + (1/2 x base x height)

Area{A} = (5 x 2) + (1/2 x 1 x 2)

Area{A} = 10 + 1

Area{A} = 11 square units

Total area of the region {A + B} as -

Total Area{A + B} = 11 + (1/2 x 10 x 5)

Total Area{A + B} = 11 + 25

Total Area{A + B} = 36 square units

The probability that a point randomly chosen in the large triangle is also in Region A will be -

P{A} = (Area{A}/Total Area{A + B})

P(A) = 11/36

Therefore, the probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.

Answer:

i think A is answer you should to do

Answer: The answer is option C: $17,925.00.

Step-by-step explanation: Using the simple interest formula:

I = Prt

where I is the interest, P is the principal, r is the interest rate, and t is the time in years.

We can find the interest earned over the 6 years:

I = P * r * t = $15,000 * 0.0325 * 6 = $2,925

Adding the interest to the principal, we get the balance at the end of the 6 years:

Balance = Principal + Interest = $15,000 + $2,925 = $17,925

Therefore, the answer is option C: $17,925.00.

The three true statements about the two triangles are:
- Î"xyz is similar to Î"x'y'z'
- Angle xzy is congruent to Angle y'z'x'.
- The length of yx is twice the length of y'x'

1. Î"xyz ~ Î"x'y'z': The two triangles are similar because the reflection preserves the shape and the dilation with a scale factor of one-half changes the size proportionally.
2. Angle xzy ≅ Angle y'z'x':

Since the triangles are similar, their corresponding angles are congruent.

The reflection and dilation transformations do not affect the angle measures.
3. yx = 2y'x':

Due to the dilation with a scale factor of one-half, the corresponding side lengths of the triangles have a ratio of 2:1. So, the length of yx is twice the length of y'x'.

Answer:

70

Step-by-step explanation:

ok, so since you want to find out what the profit is, first you take the times you won and multiply the amount you got for winning so 50*2=100. now that you have 100 you take the money you spent and multiply it by the number of times you played the game so 20*3=30. now that you have those you have everything you need to finish the question. you take the amount you spent per play (30) and subtract it from what you won (100). 100-30=70

Answer: The Profit is $40

Step-by-step explanation:

It costs $20 per turn so if you win you get $30

So $30+$30 = $60 (Because you won twice)

The subtract the $20 you lost $60-$20 = $40

So you earned $40!

The random variables X and Y, representing the sum of dice values and the number of times an odd number appears, respectively, are not independent.

The outcome of one variable affects the outcome of the other. To prove this, consider the case when k = 1, where we roll a single fair die. In this scenario, X can take values from 1 to 6, and Y can take values from 0 to 1. If X = 1, then Y must be 1 because there is only one odd number, 1, in the possible outcomes. Similarly, if X is any other value from 2 to 6, Y must be 0 because there are no odd numbers in these outcomes. This dependency between X and Y demonstrates that they are not independent.

To further explain, let's consider the probabilities. For X and Y to be independent, the joint probability distribution should be equal to the product of the marginal probabilities. However, in this case, the probabilities of X and Y are not independent. The probability of X = 1 is 1/6, and the probability of Y = 1 given X = 1 is 1. On the other hand, the probability of X = 1 is 1/6, but the probability of Y = 0 given X = 1 is 0. Therefore, the joint probability distribution of X and Y does not match the product of the marginal probabilities, confirming their dependence.

If the correlation between two variables is .496, 75.4%. much of the variance has not been accounted for.

What is variable?

In the context of statistics and mathematics, a variable is a characteristic or quantity that can vary or take different values.

The correlation coefficient, which ranges from -1 to 1, measures the strength and direction of the linear relationship between two variables. If the correlation between two variables is 0.496, it indicates a moderate positive correlation.

The coefficient of determination, also known as R-squared, represents the proportion of the variance in one variable that can be explained by the other variable. In this case, if the correlation is 0.496, then the coefficient of determination is \((0.496)^2 = 0.246.\)

Therefore, 24.6% of the variance has been accounted for by the correlation, and the remaining 75.4% of the variance has not been accounted for.

The mass of the decoration is 200 kg and for each passenger car is 550 kg

From the question, we have the following parameters that can be used in our computation:

These can be represented as

(6, 3500) and (4, 2400)

The slope of the above points represent the mass of each passenger car

This is calculated as

Slope = Difference in mass/Difference in number of cars

So, we have

Slope = (3500 - 2400)/(6 - 4)

Evaluate

Slope = 550

When there are no passenger cars in the train, we have

(0, Mass of decoration)

Using the slope formula, we have

Slope = (Mass of decoration - 3500)/(0 - 6)

So, we have

Slope = (Mass of decoration - 3500)/(-6)

This gives

(Mass of decoration - 3500)/(-6) = 550

Cross multiply

Mass of decoration - 3500 = -3300

Add 3500 to both sides

Mass of decoration = 200

Hence, the mass of decoration is 200 kg

The answer is (B) 1/e.

To find the absolute maximum value of f(x) = ln(x)/x, we need to find the critical points and endpoints of the function and then evaluate f(x) at these points to determine the maximum value.

First, we find the derivative of f(x):

f'(x) = (1/\(x^2\)) * (xln(x) - 1)

Setting f'(x) = 0, we get:

xln(x) - 1 = 0

Solving for x, we get:

x = 1/e

Since f(x) is only defined for x > 0, the only critical point is x = 1/e.

Next, we evaluate f(x) at the critical point and at the endpoints of the domain of the function:

f(1/e) = ln(1/e)/(1/e) = -1/e

f(0+) = lim(x→0+) ln(x)/x = lim(x→0+) (1/x) / 1 = ∞

f(∞) = lim(x→∞) ln(x)/x = lim(x→∞) (1/x) / (1/x) = 1

Since f(x) approaches infinity as x approaches 0+, and f(x) approaches 1 as x approaches infinity, the absolute maximum value of f(x) occurs at x = 1/e, and the maximum value is f(1/e) = -1/e.

Therefore, the answer is (B) 1/e.

(C) Regression analysis is the statistical method commonly used to estimate the level and trend in a time series by modeling the relationship between the data and independent variables.

Regression analysis is the statistical method used to estimate the level and trend in a time series. Time series data represents observations taken at different points in time and is commonly used to analyze trends and patterns over time.

Regression analysis allows us to model the relationship between a dependent variable (in this case, the time series data) and one or more independent variables (such as time or other relevant factors). By using regression analysis, we can identify the underlying trend in the time series and estimate its level.

The regression model captures the relationship between the dependent variable (the time series) and the independent variable(s) by fitting a line or curve that best represents the data. This line or curve helps to identify the overall trend and level of the time series.

While moving average, simulation method, covariance analysis, and correlation analysis are useful techniques in analyzing time series data, they are not specifically designed to estimate the level and trend in a time series. Therefore, (C) regression analysis is the most appropriate method for estimating the level and trend in a time series.

Answer:

5 hours

Step-by-step explanation:

737mi / 11hr = 67mph

335mi / 67mph = 5hr

==================================================

Here are two ways to solve

Method 1

First determine her speed if she goes 737 miles in 11 hours.

distance = rate*time

d = r*t

737 = r*11

737 = 11r

11r = 737

r = 737/11

r = 67

Her speed is 67 mph. Use this to find how long it would take if she drove 335 miles.

d = r*t

d/r = t

t = d/r

t = 335/67

t = 5 hours is the time it takes to drive 335 miles assuming Martina drives at the same speed.

---------------------------------------------------------------------

Method 2

We can use a proportion to solve

(distance 1)/(time 1) = (distance 2)/(time 2)

(737 miles)/(11 hours) = (335 miles)/(x hours)

737/11 = 335/x

737*x = 335*11 .... cross multiply

737x = 3685

x = 3685/737 ..... divide both sides by 737

x = 5

We get the same answer of 5 hours.
