If you picked a card at random, then the probability of picking a three is 1 / 4 or 25 %.

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us. When this happens, we say that there is a chance that the event will happen or not. In general, probability has many wonderful uses in games, in business to make forecasts based on likelihood, and in this emerging branch of artificial intelligence.

The probability that an event will occur is determined by the probability formula. The ratio of positive outcomes to all possible outcomes is used as the formula to determine an event's probability.

The probability that you can pick a three out of the cards given is:

= Number of cards of 3 / Number of total cards

= 1 / 4

= 25 %

Answer:

Step-by-step explanation:

Using the given equation, we can solve for t when s is equal to 22.

22 = -2.7t^2 + 40t + 6.5

Subtracting 6.5 from both sides, we get:

15.5 = -2.7t^2 + 40t

Adding 2.7t^2 to both sides, we get:

18.2t^2 = 15.5 + 40t

Subtracting 40t from both sides, we get:

18.2t^2 - 40t = 15.5

Dividing both sides by 18.2, we get:

t^2 - 2.2t = 0.855

Factoring, we get:

(t - 1)(t - 0.855) = 0

Setting each factor equal to 0 and solving, we get:

t = 1 and t = 0.855

Therefore, the ball will reach a height of 22ft after 1 second and 0.855 seconds.

Ratio:

In mathematics, ratios indicate the number of times one number contains another number. For example, if you have 8 oranges and 6 lemons in your fruit bowl, the ratio of oranges to lemons is 8 to 6 (that is, a ratio of 8:6, or 4:3). Similarly, the ratio of lemons to oranges is 6:8 (or 3:4) and the ratio of oranges to whole fruit is 8:14 (or 4:7). Ratios can be given by giving both constituent numbers written "a to b" or "a : b", or by giving only the value of their quotient a/b.

When comparing one data point (A) to another data point (B), the formula is A/B. That is, divide information A by information B. For example, if A is 5 and B is 10, the ratio is 5/10. Solve the equation. Divide data A by data B to get the ratio.

To find out how many plants are not flowers, we need to subtract the number of flowers from the total number of plants.

We know that 2/20 of the plants are flowers, and we can use this information to find out how many plants are flowers. To do this, we can multiply the total number of plants (260) by the fraction of plants that are flowers (2/20).

260 x (2/20) = 260 x 0.1 = 26

So there are 26 plants that are flowers.

To find the number of plants that are not flowers, we subtract the number of flower plants from the total number of plants:

260 - 26 = 234

So there are 234 plants that are not flowers.

4/3 is the valve of |MN| ^2 of a given tetrahedron  in which M AND N are the mid points of the edges AB and CD . is explained below:

on observing the diagram we can estimate that image of point D in the plane is given  by ABC is    [tex](2\sqrt{2} , 0 , -2 )[/tex]  and volume of tetrahedron ACBM is 4/3

AB=BC=CD=AD =a

hence a =[tex]2\sqrt{2}[/tex]  then MA =2 ; 2b^2 =4  ; therefore , b=[tex]\sqrt{2}[/tex]

Any two angles whose sum is 146 degrees must both be less than 146 degrees. This can be supported by the Triangle Sum Theorem, which states that the sum of the measure of the interior angles of a triangle is 180 degrees.

The Triangle Sum Theorem states that the sum of the measure of the interior angles of a triangle is always 180 degrees. Therefore, if two angles add up to 146 degrees, then both of those angles must be less than 146 degrees. This is because the remaining angle must make up the difference to reach the total of 180 degrees.

Therefore, any two angles whose sum is 146 degrees must both be less than 146 degrees.

The volume of the largest right circular cylinder (in cubic units) that fits in a sphere of radius 4 units is 154.7 cubic units.

First, draw a diagram. The diagram shows the cylinder inscribed in the sphere. Given that in the diagram the height, h, we can find the radius of the cylinder in terms of r using the Pythagorean Theorem.

h represents half of the total height of the cylinder. choose h instead of h² to simplify things better.

To find the volume of the cylinder, we need to multiply the area of the top by the total height of the cylinder. In other words;

V = π(radius of cylinder)²(height of cylinder)

V = π(√r²−h²)²(2h)

V = 2πh(r²−h²)

V = 2π(r²h−h³)

d/dxV(h) = 2π(r²−3h²) = 0

The 2π divides out and we are left with;

r²−3h² = 0

After some rearranging;

h² = r²/3

Take the square root of both sides.

h = r/√3

To find the volume, we need to put this into the volume equation.

V = 2πh(r²−h²) = 2π(r/√3){r²−(r/√3)²}

V = (2πr/√3)(r²−r²/3)

V = (2πr/√3){(3r²−r²)/3}

V = (2πr/√3)(2r²/3)

V = 4πr³/3√3

V = 4√3πr³/9

Now, put the value of r in the above equation, and we get

V = 4√3π(4)³/9

V = 256√3π/9

V = 154.7 cubic units

There are no two consecutive odd numbers that satisfy the given condition.

What are the consecutive numbers?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.

consecutive numbers are defined as numbers that follow each other in the natural sequence of numbers either from largest to smallest or from smallest to largest.

Let x be the smaller odd number and y be the larger odd number. Since y is larger than x, we know that y = x + 2.

The problem states that:

2y - 2x = 21

We can substitute in the value of y:

2(x + 2) - 2x = 21

Solving for x:

2x + 4 - 2x = 21

4 = 21

The distance between the tips of the hands is changing at a rate of 55 inches per minute at 9 o'clock.

To find the distance between the tips of the hands, we can use the Pythagorean theorem:

distance = $\sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10$

As the clock moves, the minute hand will rotate 360 degrees in 60 minutes, or 6 degrees per minute, and the hour hand will rotate 360 degrees in 12 hours or 0.5 degrees per minute.

To find the rate at which the distance between the tips of the hands is changing, we need to find the rate at which the angle between the hands is changing.

We can use the fact that the angle between the hands is equal to the difference in the angular velocities of the hands.

Angular velocity of the minute hand = 6 degrees/minute

Angular velocity of the hour hand = 0.5 degrees/minute

Angular velocity of the distance between the tips of the hands = 6 - 0.5 = 5.5 degrees/minute

To convert this to distance per minute, we can use the fact that the distance between the tips of the hands is equal to the length of the hour and minute hand multiplied by the sine of the angle between them.

Distance per minute = 10 * 5.5 degrees/minute = 55 inches/minute

So, the distance between the tips of the hands is changing at a rate of 55 inches per minute at 9 o'clock.

The measure of angle R, in degrees, is 150°.

A parallelogram is a quadrilateral or four-sided shape, that has opposite sides that are parallel to each other. The opposite sides of a parallelogram are equal in length, and the opposite angles are also equal in measure.

In a parallelogram, opposite angles are equal, so if the measure of angle P is five times the measure of angle Q, then the measure of angle R must also be five times the measure of angle Q.

Let's call the measure of angle Q "x". Then the measure of angle P is 5x, and the measure of angle R is 5x.

Therefore, the measure of angle R in degrees is 5x degrees.

We know,

All of the angles added together = 360°

∠5Q +∠Q+∠5Q+∠Q = 360    Solve for Q

∠12Q = 360  

⇒  ∠Q = 30°

then ∠P = ∠5Q = 5(30) = 150°
