The given probability is based on conditions of two events, hence it is called as conditional probability and it's formula according to the events is option.a  [tex]p(\frac{C}{A})=\frac{p(\frac{A}{C}).p(C)}{p(A)}[/tex]

Bayes' rule is a mathematical theorem that allows you to modify probability statements in response to new information. With this rule, you can reverse the conditional probability statement and find the probability of the first event occurring given the probability of the second event occurring by using the probability of the second event occurring given the probability of the first event occurring.The first event in this case is that the bolt is defective (event C). The second occurrence is that it was selected from the first machine (event A). As a result, given that the bolt is from the first machine, we can state the conditional probability that it is defective.

Hence, the formula is  [tex]p(\frac{C}{A})=\frac{p(\frac{A}{C}).p(C)}{p(A)}[/tex].

the probability to get two consecutive reds will be 19.75%.

What is probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

A fair spinner has 9 equal sections: 4 red, 3 blue and 2 green.

The probability of not getting two consecutive red is  1  minus the probability of getting two consecutive greens. Since the spinner is fair, the probability of getting a green on any one spin is  4/9

Since consecutive spins are independent, the probability of getting two consecutive red is (4/9)² = 16/81= 19.75%

Hence the probability to get two consecutive reds will be 19.75%.

Step-by-step explanation:

To solve for x, distribute the 3/5. This gives us 3/5x - 21/50 = -314. Add over 21/50 to the other side, allowing for 3/5x to equal -313 29/50. Divide by 3/5 on both sides and we get x equal to -522 19/30. This is the final answer as a mixed number and is also in simplest form.

Answer:

D)  The y-axis only tests whether x = 0 has been mapped to more than one y coordinate.

Step-by-step explanation:

The y-axis is a vertical line and intersects the x-axis (horizontal line) at the origin (0, 0) when both x and y are zero.

Vertical line test

A graph represents a function if and only if all vertical lines intersect the graph at most once.

Therefore, the strategy of using only the y-axis as the vertical line in the vertical line test is flawed because the y-axis only tests whether x = 0 has been mapped to more than one y-coordinate.

Vertical angles are pairs of angles that are located on opposite sides of a line and are equal in measure, the value of k is 9.

Vertical angles are pairs of angles that are located on opposite sides of a line and are equal in measure. They are formed when two lines intersect, and they are always congruent, or equal in measure.

That if one angle measures 130°, the measure of its vertical angle must also be 130°.

If the other angle has a measure of (8k + 58)°, and it is a vertical angle to the angle that measures 130°, then it must also have a measure of 130°.

We can set up the equation 130 = 8k + 58 and solve for k to find the value of k.

Subtracting 58 from both sides gives us 72 = 8k. Dividing both sides by 8 gives us k = 9.

Therefore, the value of k is 9.

A. The relationship between the number of pounds of grapes sold (x) and the total price (y) can be described by the equation y = 2.25x.

The required details for pounds in given paragraph

This equation can be derived from the data in the table by substituting the values for x and y and solving for the coefficient 2.25. For example, for x = 2 pounds of grapes, we have y = $4.50, so 4.50 = 2.25 * 2. Similarly, for x = 4 pounds of grapes, we have y = $9.00, so 9.00 = 2.25 * 4. We can use this equation to find the total price for any number of pounds of grapes sold.

B. The total price of 17 pounds of red peppers is $31.60. The 1.80 in the equation p = 1.80r represents the price per pound of red peppers. In this case, 1.80 dollars is the price per pound of red peppers, and r is the number of pounds of red peppers that are being purchased. Therefore, the total price of r pounds of red peppers is equal to 1.80 dollars per pound multiplied by the number of pounds of red peppers being purchased.

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

f(x) = x³

g(x) = (-2x)³

First, we have the transformation to be:

From f(x) = x³ to f'(x) = (−x)³

This means the function is reflected across the y-axis

So, we have the following representation

f'(x) = f(-x)

Next, we have:

From f'(x) = (−x)³ to g(x) = (−2x)³

This means the function is horizontally stretched by a factor of 1/2

$600 is the regular price of the stainless steel

Percentage simply means the number or ratio that can be expressed as a fraction of 100. In this case, when we have to calculate percent of a number, we then divide the number by the whole and multiply by 100.

Given: Sales price with discount = $479.99, savings = 20% off. This implies there is a 20% discount.

Let P represent the regular price. Thus, we can write:

P - (20% of P) = $479.99

P - 0.2P = 479.99

0.8P = 479.99

P = 479.99 / 0.8
