Step-by-step explanation:

The measure of angle 2 is 58 degrees

The figure that completes the question is added as an attachment

The given parameters are:

Both angles add up to 90 degrees.

So, we have:

3x - 4 + 4x + 10 = 90

Evaluate the like terms

7x = 84

Divide both sides by 7

x =12

Substitute x =12 in Angle 2 = 4x + 10

Angle 2 = 4 * 12 + 10

Evaluate the expression

Angle 2 = 58

Hence, the measure of angle 2 is 58 degrees

The distribution of x is a continuous probability distribution. This could include distributions such as the normal distribution, the exponential distribution, the gamma distribution, and others.

1. A random variable is a variable whose values can be randomly selected from a given set.

2. A cumulative distribution function (CDF) is a function that gives the probability that a random variable takes on a value less than or equal to a given value.

3. A strictly increasing CDF means that for any two values of the random variable, if one value is greater than the other, then the probability of the larger value is greater than the probability of the smaller value.

4. A continuous CDF means that the CDF does not have any jumps or discontinuities.

5. Therefore, the distribution of the random variable x is a continuous probability distribution, which could include distributions such as the normal distribution, the exponential distribution, the gamma distribution, and others.

The x-intercepts are the points at which the graph cuts the x-axis.

They are

2. The meaning of the x-intercepts in this problem are the points where the plane takes off and lands on the ground.

The plane takes of at x = 2.5 s and lands at x = 7.5 s

The probability distribution for X is given below:

Probability of no even number, (X = 0)= 1/2

Probability of one even number, (X = 1) = 1/2

Probability of two even numbers, (X = 2) = 1/8

The probability distribution for X is found as follows:

The probability that an even number is not selected i.e. X = O

P(X = 0) =  (2/4 * 2/4) + (2/4 * 2/4)

P(X = 0) = 1/2

The probability that an even number is selected once i.e. X = 1

P(X = 1) =  (2/4 * 2/4) + (2/4 * 2/4)

P(X = 1) = 1/2

The probability that an even number is selected twice i.e. X = 2

The bunch of roses costs $12/$3 = 4 times as much as a single rose.

What is arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term.

The bunch of roses costs 4 times as much as a single rose.

To see why, we can divide the cost of the bunch of roses by the number of roses it contains. If a bunch of roses costs $12 and contains, say, 4 roses, then each rose in the bunch costs $3. On the other hand, a single rose costs $3 on its own.

Therefore, the bunch of roses costs $12/$3 = 4 times as much as a single rose.

let the required cost be Rs x

Here , the quantities of sugar and their cost are direct proportion

So, 10 : 15 = 8: x

\( \: \frac{10}{15} = \frac{880}{x} \\ x = \frac{880 \times 15}{10} \\ x = Rs1320\)

•°• 50 : 75. = x : 21

\( \frac{50}{75} = \frac{x}{21} \\ x = \frac{50 \times 21}{75} \\ x = 14 \: days \\ \)

Hence, the provisions last for 14 days for75 students

No, because (6, 4) is below the line.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, An inequality Y > - (1/2)x + 7.

Answer:

See graph attached

Step-by-step explanation:

Our life is simple because the equation \(y=2x+2\) is already put in slope-intercept form.

This form is called slope-intercept because it states exactly what it's called: The number multiplied by \(x\) (the constant of proportionality, in this case, 2) is the slope - and the y-intercept is what is being added to the equation (in this case, also 2, since there is a +2 at the end.)

With this info, we can start graphing.

We know that the y-intercept is 2, meaning one point will be (0,2).

We also know that the slope is 2, meaning every time x increases by 1, y will increase by 2. So the next point is (1, 4), the next is (2, 6), and so on.

Hope this helped!

The function F(x)=0.2F(x)=0.2 is not an exponential decay function. It is a constant function where the output value is always equal to 0.2, regardless of the input value xx.

An exponential decay function is typically in the form f(x)=a⋅bxf(x)=a⋅bx, where aa and bb are constants and bb is a value between 0 and 1. As xx increases, the exponential decay function decreases exponentially.

For example, an exponential decay function could be f(x)=0.2⋅(0.5)xf(x)=0.2⋅(0.5)x, where the base 0.50.5 represents the decay factor. As xx increases, the value of the function decreases rapidly.

In summary, an exponential decay function follows the pattern of decreasing values as xx increases, while the function F(x)=0.2F(x)=0.2 represents a constant value regardless of the input xx.
