2/221 is the probability that a 2-card hand has two queens, two kings, or one of each.

Now, calculate the probability as follows:

Then, it can be either KK or QQ.

So required probability = 2king or 2 queen

Therefore, the probability that a 2-card hand (drawn from a standard deck of 52) has two queens, two kings, or one of each is 2/221.

Answer:

[2 , ∞)  

Step-by-step explanation:

y = sqrt( x-2)

The domain is the values that x can take

Since we have a square root

Domain: [2 , ∞)  since the square root must be greater than or equal to zero

The range is the values that y can take

The square root starts at 0 and increases

Range [0,∞)

The inverse swaps the domain and range

Range: [2 , ∞)

When you add -1/4 to itself four times, you get: -1
When you multiply -1/4 by 4, you also get: -1.
Yes, both the results are same which is: -1.

To answer your question, let's break it down into two parts:

1. What do you get if you add -1/4 to itself four times?
To find the answer, you simply add -1/4 four times:
(-1/4) + (-1/4) + (-1/4) + (-1/4) = -1

2. What is -1/4 × 4?
To multiply -1/4 by 4, you perform the multiplication:
(-1/4) × 4 = -1

In conclusion, when you add -1/4 to itself four times, you get -1, and when you multiply -1/4 by 4, you also get -1.

The approximate amount of paint needed =  438.03 cm²

The correct answer is an option (D)

We know that the formula for the surface area of the cylinder is :

A = 2πrh + 2πr²

Here, the diameter of the can is 9 sm

So, the radius of the can would be,

r = d/2

r = 9/2

r = 4.5 cm

And the height of the can is h = 11 cm

Since the can is cylindrical, we use above formula of surface area of the cylinder to find the amount of paint needed.

Using above formula,

A = 2πrh + 2πr²

A = 2π(4.5)(11) + 2π(4.5)²

A = 311.02 + 127.01

A = 438.03 cm²

Therefore, the correct answer is an option (D)

The probability the mean age at heart attack after using cocaine is greater than 42 is 0.9192. Hence, the correct option is D. 0.9192.

The standard deviation of the age of people who suffered heart attacks soon after using cocaine was 10 years. In a random sample of size 49, what is the probability the mean age at heart attack after using cocaine is greater than 42?We are given the following details:

The mean age of people in the study who suffered heart attacks soon after using cocaine was only 44.

Standard deviation = 10

Sample size = 49

Now we need to find the z-score using the formula:

z = (x - μ) / (σ / √n)

wherez is the z-score

x is the value to be standardized

μ is the mean

σ is the standard deviation

n is the sample size.

Substitute the values in the formula as given,

z = (42 - 44) / (10 / √49)z = -2 / (10/7)

z = -1.4

Probability of z > -1.4 can be found using the standard normal distribution table or calculator.

P(z > -1.4) = 0.9192

Therefore, the probability the mean age at heart attack after using cocaine is greater than 42 is 0.9192. Hence, the correct option is D. 0.9192.

The type of variables recorded

Number of people in party- Discrete;

mess price per person-continuous

The number of people in a party is generally recorded as a separate variable. separate variables are characterized by distinct, separate values that can only take on whole figures or specific orders.

In this case, the number of people in a party can only be whole figures(e.g., 1, 2, 3,etc.), making it a separate variable.

On the other hand, the average price of the mess per person is recorded as a continuous variable. continuous variables can take on a range of numerical values, including fragments or numbers.

In the environment of mess prices, the average price can vary continuously, similar as$10.50, $15.75, etc., allowing for horizonless possible values.

Thus, the mess price per person is a continuous variable.

Answer:

Height of the tree = 6 meters.

Step-by-step explanation:

P.S - The exact question is -

The graph is as follows :

Here Base = 8 m , Hypotenuse = 10 m

As, we know that By Pythagoras theorem,

( Hypotenuse )² = ( Base )² + ( Perpendicular )²

⇒(10)² = (8)² +  ( Perpendicular )²

Let the height of the tree = x

∴ we get

(10)² = (8)² +  ( x )²

⇒100 = 64 + x²

⇒100 - 64 = x²

⇒36 = x²

⇒x = √36

⇒x = 6

∴ we get

Height of the tree = 6 meters.

What is a radian?

The standard unit of angular measurement used in many branches of mathematics is the radian, indicated by the symbol rad. It is the unit of angle in the International System of Units. Previously, the unit was a SI supplementary unit.

Here, we have

Radius = 32

The car has swept out 1.8 radians since it started moving.

1 radian = 57.3°c

Since the car revolve around 1.8 radian

1.8×57.3 = 103.14°c

Using the formula

©/360×2πr

103.14/360×(2×22/7×32) = 57.57m

Average velocity of the car as calculated from the given data is 6m/s.

The average velocity is calculated by dividing the total distance travelled by the whole time that has passed. Given the velocity as a function of time, you may integrate the velocity function from t = 4 to t = 8 to determine the total distance travelled.

The opposite of taking a derivative is to integrate; in other words, the function I get when I take a derivative is 2t1/2 + 1. Assuming you are aware of how to do that If not, you can input the aforementioned integral into your TI-84 to obtain the result.

The integral turns out to be

(4/3)t^3/2 + 4t so x(t)

= (4/3)t3/2 + 4t and x(8) - x(4)

= (4/3)(8)3/2 + 4(8) - [(4/3)(4)3/2 + 4(4)]

= 24 meters

The distance travelled in total was 24 meter and it took 4 seconds (8-4) to do it, so the average velocity is 24 /4 = 6 m/s.

(a) i) The price of the television on the first day of the sale is £360

    ii) The price of the television on the third day of the sale is £288

(a)

i) On the first day of the sale, the price of the television is reduced by 20% of £450, which is:

20/100 × £450 = £90

So the price of the television on the first day of the sale is:

£450 - £90 = £360

ii) On the third day of the sale, the price of the television is reduced by 20% of the price on the second day of the sale. To find the price on the second day, we need to calculate the reduction on the first day and subtract it from the original price:

Reduction on first day = 20/100 × £450 = £90

Price on second day = £450 - £90 = £360

On the second day of the sale, the price of the television is reduced by 20% of £360, which is:

20/100 × £360 = £72

- 2x +2y = 8 ( subtract 2y from both sides )

- 2x = - 2y + 8 ( divide through by - 2 )

x = y - 4

substitute x = y - 4 into (1)

3(y - 4) - 9y = 9

3y - 12 - 9y = 9

- 6y - 12 = 9 ( add 12 to both sides )

- 6y = 21 ( divide both sides by - 6 )
