Answer:

x=135 degrees

Step-by-step explanation:

The total angles added up in a triangle is 180-degrees (ABC)

69+66+A=180

A=45

Line CD is a 180-degree line so angle x would be:

180-45 = 135 degrees

The shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

What is a normal distribution?

A normal distribution is a function on some random variables, which represent the set of all those random variables in a symmetrical bell shape about the mean value.

It shows that the probability of occurrence of some data which is distributed over a function is more at or around the mean.

It is also known as probability distribution curve.

The normal distribution has two parameters:

What is the shape of the normal distribution?

The normal distribution curve is at it's peak at the mean value. This shows that the probability of occurrence of the data or value is more concentrated or distributed about the mean. It is also symmetric about the mean. As we more further from the mean, we see that the normal distribution curve gradually decreases showing that the probability of occurrence of the data or the values decreases. The shape that this curve forms is like a bell-shaped. So the shape of normal distribution is bell shape.

Hence, the shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

Yes, the probability assignments given to the four outcomes of an experiment are valid. Probabilities are calculated subjectively, and the decision maker assigned probabilities to the four outcomes of the experiment, which is perfectly acceptable.

Probability is a numerical measure of the likelihood of an event occurring, ranging from 0 to 1.

An event that is certain to happen has a probability of 1, while an event that is impossible has a probability of 0. The probability of any other event lies somewhere between 0 and 1.

Probability assignments, which are subjectively determined probabilities, are valid as long as they meet the following criteria:

In this case, the probability assignments are valid because they meet both of the above criteria. The probabilities assigned are between 0 and 1, and when the probabilities are added together, the sum is 1.

Answer:

The answer is x = 9

We use Pythagoras theorem to form the equation and solve for x

That's

a² = b² + c²

where a is the hypotenuse

we get

(x + 6)² = 12² + x²

Expand

x² + 12x + 36 = 144 + x²

Group like terms

We have

x² - x ² + 12x = 144 - 36

12x = 108

Divide both sides by 9

That's

12x/12 = 108/12

x = 9

Hope this helps you.

Answer:

Solution,

AB=(perpendicular)=X

AC(hypotenuse)=X+6

CB(Base)=13

Using Pythagoras theorem,

\( {h}^{2} = {p}^{2} + {b}^{2} \\ {(x + 6)}^{2} = {x}^{2} + {(12)}^{2} \\ {x}^{2} + 12x + 36 = {x}^{2} + 144 \\ 12x + 36 = 144 \\ 12x = 144 - 36 \\ 12x = 108 \\ x = \frac{108}{12} \\ x = 9\)

There are 7200 ways for the senate committee to sit around a circular table.

To solve this problem, we can use the formula for circular permutations: (n-1)!/d, where n is the total number of people and d is the number of ways in which they can be distinguished. In this case, n is 11 (5 democrats + 5 republicans + 1 independent) and d is 1 (since all the members of each party sit together, they are not distinguishable from one another). Plugging these values into the formula, we get

the value of the variable newexample is -25.The given statement is a conditional (ternary) operator expression in the form:

condition ? expression1 : expression2

If the condition (50 <= 75) is true, then the value of newexample will be expression1 (50-75). If the condition is false, then the value of newexample will be expression2 (75-50).

Since 50 is indeed less than or equal to 75, the condition is true. Therefore, the value of newexample will be the result of expression1, which is 50-75.

Performing the subtraction, we get:

newexample = 50 - 75 = -25

The coordinate of point D that divides segment MJ in the ratio 7/16 is (13, 8)

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let us assume that point M is at (20, 1) and point J is at (4, 17), hence:

If point D(x, y) is 7/16 M to J, then:

x = (7/16)(4 - 20) + 20 = 13

The value of the rectangular cuboid will be 6,355.725 mm³.

Given that:

Length, L = 7.50 x 10² mm

Width, W = 102.1 mm

Height, H = 0.083 mm

A cuboid's volume is determined by multiplying its length, breadth, and height. A cuboid is a six-sided, three-dimensional geometry where the length, breadth, and height correspond to the three perpendicular sides. Add the length, breadth, and height together to obtain the volume.

The volume of the cuboid is calculated as:

V = 7.50 x 10² mm x 102.1 mm x 0.083 mm

V = 6,355.725 mm³

Answer: 20

Step-by-step explanation:

15 divided by 3 equals 5 and 15 plus 5 equals 20.

he required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Let’s assume the general solution of the given differential equation is,

y=e^{mx}

By taking the derivative of this equation, we get

\(\frac{dy}{dx} = me^{mx}\\\frac{d^2y}{dx^2} = m^2e^{mx}\\\frac{d^3y}{dx^3} = m^3e^{mx}\\\frac{d^4y}{dx^4} = m^4e^{mx}\\\)

Now substitute these values in the given differential equation.

\(\frac{d^4y}{dx^4}-2\frac{d^2y}{dx^2}-8y\\=0m^4e^{mx}-2m^2e^{mx}-8e^{mx}\\=0e^{mx}(m^4-2m^2-8)=0\)

Therefore, \(m^4-2m^2-8=0\)

\((m^2-4)(m^2+2)=0\)

Therefore, the roots are, \(m = ±\sqrt{2} and m=±2\)

By applying the formula for the general solution of a differential equation, we get

General solution is, \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

Hence, the required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Answer:

solution is (-2, 2) so x-coordinate of solution is -2

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

First, we have to write down both equations.

y = x + 4

3y = -2x + 2

Now we already have an equation that we can plug into the other equation.

= 3(x + 4) = -2x + 2

= 3x + 12 = -2x + 2

= 5x + 12 = 2

= 5x = -10

x = -2

Now we know that x = -2, and the question asks for the x-coordinate, which is -2.

Answer:

a. After 10 minutes of hiking, Kiran will have covered a distance of:

distance = rate × time

distance = 0.04 mile/min × 10 min

distance = 0.4 mile

So, his remaining distance on the trail will be:

remaining distance = total distance - covered distance

remaining distance = 1.8 mile - 0.4 mile

remaining distance = 1.4 miles

Therefore, Kiran's remaining distance on the trail after 10 minutes of hiking is 1.4 miles.

b. We can use the same formula to find out how far Kiran will have walked after a certain amount of time:

distance = rate × time

We know that Kiran walks at a rate of 0.04 mile a minute, and we want to find out how much time it will take him to cover the remaining distance of 0.2 mile. So we can rearrange the formula to solve for time:

time = distance / rate

time = 0.2 mile / 0.04 mile/min

time = 5 minutes

Therefore, Kiran will have 0.2 mile left on the trail after 5 minutes of walking.

An equivalent decimal, fraction and percent is C) 0.45, 4/5, 45%.

To understand why this is the correct choice, we need to look at how decimals, fractions, and percentages are related. Decimals are just another way of representing fractions, where the denominator is a power of 10. For example, 0.45 is the same as 45/100 or 9/20.

Percentages, on the other hand, are just a way of representing fractions with a denominator of 100. So, 45% is the same as 45/100 or 9/20.

The other options do not have equivalent representations of decimals, fractions, and percentages.

In conclusion, understanding the relationships between decimals, fractions, and percentages is essential to solving problems like these. The key is to remember that they are just different ways of representing the same value, and with a bit of practice, it becomes second nature to recognize equivalent representations.

Therefore, option C shows an equivalent decimal (0.45), fraction (4/5), and percent (45%).
