sorry man I'm tired but here's ya first set of answers

The probability that the spinner landing on a number that is a multiple of 5 or 2 is 0.6, calculated by dividing the number of favorable outcomes (9) by total outcomes (15).

To find the probability that the spinner lands on either a multiple of 5 or a multiple of 2, we first need to identify these numbers.

The multiples of 5 between 1 and 15 are 5, 10, and 15. The multiples of 2 between 1 and 15 are 2, 4, 6, 8, 10, 12, and 14.

Note that 10 is both a multiple of 2 and 5. When we combine these sets, we have 9 unique numbers out of total 15. This gives us a total of 9 favorable outcomes.

The probability is the ratio of favorable outcomes to the total number of outcomes. So, the required probability would be 9/15 or 0.6 when simplified.

The probability that the spinner lands on a multiple of 5 or a multiple of 2 is 9 out of 15, or 0.6 (60%).

The subject of this question is probability, which falls under Mathematics. To determine the probability that a spinner numbered from 1 to 15 would land on a multiple of 5 or a multiple of 2, we need to first identify the amount of numbers that meet these criteria. The multiples of 5 between 1 and 15 are 5, 10, and 15, which totals to 3 numbers. The multiples of 2 between 1 and 15 are 2, 4, 6, 8, 10, 12, and 14, which totals to 7 numbers.

However, the number 10 is a common multiple of both 5 and 2; to avoid counting it twice, we subtract 1 from our total. Therefore, there are 3 + 7 - 1 = 9 favorable outcomes. With 15 equally likely possibilities on the spinner, the probability is then 9/15 or 0.6, meaning there's a 60% chance the spinner lands on a multiple of 5 or a multiple of 2.

Final answer:

The ordered pair that must also be on the graph of y=f(x−2)−3 is (3, -1), which is the result of shifting the original point (1,2) to account for the horizontal and vertical transformations.

Explanation:

To determine the corresponding point on the graph of y=f(x−2)−3, we begin with the given point (1,2) on the graph of f(x). This point means that f(1)=2. The function y=f(x−2)−3 shifts the graph of f(x) two units to the right and three units down. Therefore, to find the x-value for the new function that will give us the y-value of 2, we add 2 to the original x-value of 1, giving us 3. Then to find the new y-value, we subtract 3 from the original y-value of 2, giving us -1. So the new point is (3, -1).

The ordered pair that must also be on the graph of y = f(x−2)−3, given that (1,2) is a point on the graph of f(x), is (-1, -1).

When you have the transformation y = f(x−2)−3, it implies two transformations are applied to the original function f(x): a shift to the right by 2 units and a downward shift by 3 units. To find the corresponding point on the transformed graph, we need to reverse these transformations.

The original point (1,2) on the graph of f(x) represents f(1) = 2. Applying the transformation x−2 shifts the x-coordinate by 2 units to the right, resulting in f(1−2) = f(-1). This gives us the x-coordinate for the transformed point on y = f(x−2)−3.

To account for the downward shift by 3 units, we subtract 3 from the y-coordinate of the original point. Hence, f(1) = 2 becomes f(1)−3 = 2−3 = -1. This provides the y-coordinate for the transformed point on y = f(x−2)−3.

Therefore, combining the x and y coordinates, the point (-1, -1) corresponds to (1,2) on the graph of f(x), satisfying the transformations of x−2 and -3 on y, hence making it a point on the graph of y = f(x−2)−3.

Final answer:

To find the number of new games rented, set up an equation using the given information. Assume all 6 games rented were new games, and solve for the number of new games.

Explanation:

To find the number of new games rented, we can set up an equation using the information given.

Let x represent the number of new games rented and y represent the number of older games rented.

We know that the total cost of renting 6 games is $22. Therefore, we can write the equation:

4x + 2y = 22

To find the number of new games rented, we want to solve for x. We can do this by substituting a value for y and solving for x.

Let's assume all 6 games rented were new games, so y = 0.

Substituting this value into the equation gives:

4x + 2(0) = 22

Simplifying, we get:

4x = 22

Dividing both sides by 4, we find that x = 5.5.

Since we can't rent a fractional number of games, the student rented 5 new games.

By the power to power property of exponent,

That is,

[tex](a^m)^n=a^{m.n}[/tex]

Answer:

x = [tex]\frac{1}{12}[/tex] y²

Step-by-step explanation:

Any point (x, y ) on the parabola is equidistant from the focus and the directrix

Using the distance formula, then

[tex]\sqrt{(x-3)^2+(y-0)^2}[/tex] = | x + 3 |

Squaring both sides

(x - 3)² + y² = (x + 3)² ← expanding both sides

x² - 6x + 9 + y² = x² + 6x + 9 ← subtract x² + 6x + 9 from both sides

- 12x + y² = 0 ( subtract y² from both sides )

- 12x = - y² ( divide both sides by - 12 )

x = [tex]\frac{1}{12}[/tex] y²

Answer:

y²-12x = 0

Step-by-step explanation:

The formula for calculating the equation of a parabola is y² = 4ax

and x = a

To find the equation of the parabola with focus (3, 0) and directrix x = –3,

The point given (x,y) = (3,0) and x = -3

From the data given, it can be seen that a = -3 by simply comparing x = a with x = -3

Similarly, x = 3 from the given point.

Substituting the value of x = -3 in the formula for equation of a parabola gives;

y² = 4(-3)x

y²= -12x

y²-12x = 0

Answer:

Discount = $1,464  New Price =$16,836

Step-by-step explanation:

The initial price is given as $18,300.

The price is reduced by a discount of 8%.

Discount = 8% of 18300

                = 8/100 =0.08 x 18300 =$1,464.

New price = $18,300 -$1,464

                  = $ 16,836

This can also be worked out as follows:

After the discount of 8%, the new price is 92% of the initial price.

92% = .92 x  $18300 = $16,836

Answer:

Discount = $1,464  New Price =$16,836

Now, to find a, set the measures of the interior angles equal to 180.

(a + 15) + 7a + 7a = 180

Solve for a.

a + 15 + 7a + 7a = 180

15 + 15a = 180

15a = 165

a = 11

Find the angle measures by plugging 11 for a.

a + 15

(11) + 15

26

7a

7(11)

77

Check your work by adding the angles measures.

77 + 77 + 26 = 180

a = 11

Each base angle measures 77 degrees and the vertex angle measures 26 degrees.

Final answer:

To find the unknown angles in the isosceles triangle, we set up an equation using the fact that the sum of angles in a triangle is 180°, which gives a value of 11° for 'a.' Consequently, the vertex angle is 26°, and each base angle is 77°.

Explanation:

The question involves finding the unknown angle measures in an isosceles triangle when given the vertex angle and one of the base angles as algebraic expressions. Since we are dealing with an isosceles triangle, two base angles are equal, and the sum of all angles in a triangle is 180°. The vertex angle is given as (a+15)° and one of the base angles as 7a°. According to the properties of an isosceles triangle, the other base angle is also 7a°. Therefore, we can set up the equation:

(a+15)° + 7a° + 7a° = 180°

Combining like terms, we get:

15° + 15a° = 180°

Subtracting 15° from both sides:

15a° = 165°

Dividing by 15:

a = 11°

Now we can find each angle:

Vertex angle = a + 15° = 11° + 15° = 26°

Each base angle = 7a° = 7(11°) = 77°

The measures of the angles are therefore 26° (vertex angle) and 77° (each base angle).

Answer: Hello there!

initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.

You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)

Now we want to know the probability that she gets a red marble on the second pick.

Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)

this is 6/15.

now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.

if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.

Then the correct answer is C.

The probability that she gets a red marble on her second pick is 2/5.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that she gets a red marble on her second pick = [number of red marbles / (total number of marbles - 1)]

6 / 15 = 2/5

Step-by-step explanation:

a. The possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.

b. Rounded measurement in meters is 0.023 meters

a. To determine which measurements could be the actual measurement of the rainfall, we need to consider how rounding works.

When rounding to the nearest tenth of a centimeter, any measurement with a hundredth digit of 5 or greater rounds up, and any measurement with a hundredth digit less than 5 rounds down.

Given that the rounded measurement is 2.3 cm, let's evaluate the measurements:

2.251 cm: Rounds down to 2.3 cm

2.349 cm: Rounds up to 2.3 cm

2.352 cm: Rounds up to 2.4 cm

2.295 cm: Rounds down to 2.3 cm

So, the possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.

b. To convert the rounded measurement to meters, we need to divide it by 100, since there are 100 centimeters in a meter.

Rounded measurement: 2.3 cm

Conversion to meters: 2.3 cm / 100 = 0.023 meters
