The probability of drawing a green marble out of the bag without looking is 1/3.

Given that, a bag contains 1 blue, 2 green, and 3 red marbles.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Total number of outcomes =1+2+3 =6

Number of favorable outcomes = 2

Now, probability of drawing green marble

= 2/6

= 1/3

Therefore, the probability of drawing a green marble out of the bag without looking is 1/3.

The output value of g( -5 ) in the function g( x ) = −23( x - 4 )2 + 3 is 417.

A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.

Given the data in the question;

To find the g( - 5 ), replace all the occurrence of x with -5 in the function and simplify.

g( x ) = −23( x - 4 )2 + 3

g( -5 ) = −23( -5 - 4 )2 + 3

g( -5 ) = −23( -9 )2 + 3

g( -5 ) = −23( -9 × 2) + 3

g( -5 ) = −23( -18) + 3

g( -5 ) = ( -23 × -18) + 3

g( -5 ) = ( 414 ) + 3

g( -5 ) = 414 + 3

g( -5 ) = 417

Therefore, the output value of g( -5 ) is 417.

Answer:

No, It does not.

Step-by-step explanation:

(3,4) means (x,y). When you insert 3 to x and 4 to y, You get this:

5(3)-9(4)=32

If you multiply 5 and 3, You get 15.

15-9(4)=32

If you multiply 9 and 4, you get 36.

15-36=32

If you subtract 15-36, you get -21.

This is why the answer is no because -21 does not equal 32

-21 ≠ 32

Step-by-step explanation:

pls trust me i just took the test

The number of combination of 3 playing cards from 52 card deck is 22100.

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

Here, total cards = 52

         cards to be selected = 3

So, total possible combination = ⁵²C₃

                                                    = (52 X 51 X 50) / (3 X 2 X 1)

                                                   = 22100

Thus, the number of combination of 3 playing cards from 52 card deck is 22100.

Yes, this is an optimal solution for the given problem. There is no alternate optimal solution, as there is only one variable having non-zero value in the last row of the table and this is for the objective function (Z) and all other variables have zero values in the last row of the table.

The solution is feasible as all variables have non-negative values. Also, the solution is not degenerate since all the variables have non-zero values. The optimal product mix and optimal profit are:X1 = 250,

X2 = 625,

X3 = 0

Optimal profit = Rs. (30 × 250 + 40 × 625 + 20 × 0)

= Rs. 40,000

Variable X3 has zero values in the final row of the simplex table, which indicates that it is non-basic and does not contribute to the optimal profit. Therefore, the optimal product mix is:X1 = 250,

X2 = 625,

X3 = 0

The optimal profit is calculated as follows: Optimal profit = (30 × 250) + (40 × 625) + (20 × 0) = Rs. 40,000

The volume of the solid obtained by rotating the region bounded by the curves y = 8x and y = 8√x about the line y = 8 is 16π/3 cubic units.

The volume of the solid obtained by rotating the region bounded by the curves y = 8x and y = 8√x about the line y = 8 is calculated using the method of cylindrical shells.

To find the volume V of the solid, we can use the method of cylindrical shells. This involves integrating the circumference of each cylindrical shell multiplied by its height over the region bounded by the curves.

First, let's find the intersection points of the curves y = 8x and y = 8√x. Setting the equations equal to each other, we get 8x = 8√x. Solving for x, we find x = 1.

Squaring both sides, we obtain y^2 = 8, so y = ±√8 = ±2√2.

Next, we set up the integral. Since we are rotating about the line y = 8, the radius of each cylindrical shell is given by r = 8 - y.

The height of each shell is dx, as we are integrating with respect to x. The limits of integration are from x = 0 to x = 1.

Thus, the integral for the volume V becomes ∫[0 to 1] 2π(8 - 8√x) dx. Evaluating this integral, we find V = 16π/3.

False. The minimum of two independent exponential random variables is not necessarily exponential.

For two independent exponential random variables X and Y, with rate parameters λ1 and λ2 respectively, the minimum of X and Y is a random variable Z with the cumulative distribution function (CDF) given by

\(F_Z(z) = 1 - e^(-(λ1+λ2)z)\).

The survival function of Z is given by

\(S_Z(z) = e^(-(λ1+λ2)z)\).

Therefore, the probability density function of Z is

\(f_Z(z) = (λ1 + λ2)e^(-(λ1+λ2)z)\).

This is not an exponential distribution because the form of the probability density function is not of the form \(f(z) = λe^(-λz)\).

To graph y = x² + 4x + 6 with 5+ points using an x/y chart, follow these steps:

Step 1: Create an x/y chart with five rows and two columns. Label the first column x and the second column y.

Step 2: Choose five values for x. You can choose any values you want as long as you plug them into the equation in the next step. In this example, we will use -3, -2, -1, 0, and 1. Write these values in the first column of your chart.

Step 3: Plug each value of x into the equation y = x² + 4x + 6 to find the corresponding value of y. Write these values in the second column of your chart. To make it simpler, here are the calculations for each point:When x = -3: y = (-3)² + 4(-3) + 6 = 3When x = -2: y = (-2)² + 4(-2) + 6 = 2When x = -1: y = (-1)² + 4(-1) + 6 = 1When x = 0: y = (0)² + 4(0) + 6 = 6When x = 1: y = (1)² + 4(1) + 6 = 11

Step 4: Plot each point on the x/y chart. The x value goes on the horizontal axis (x-axis) and the y value goes on the vertical axis (y-axis). Once you have plotted all five points, connect them with a smooth curve to create the graph of y = x² + 4x + 6. The graph is shown in the figure below.

Answer:

You can have 2, 1/4 pieces. The answer is 2.

Step-by-step explanation:

There are 2,300 possible 5-topping pizzas that can be made with 14 different toppings and no double-orders of toppings allowed.

If the pizza parlor offers 14 different toppings and no double-orders of toppings are allowed, the number of 5-topping pizzas possible can be calculated using the combination formula:

nCr = n! / (r! × (n-r)!)

where n is the total number of items to choose from (14 toppings in this case) and r is the number of items to be selected (5 toppings for a pizza).

Therefore, the number of 5-topping pizzas possible can be calculated as:

14C5 = 14! / (5! × (14-5)!)

= (14 × 13 × 12 × 11 × 10) / (5 × 4 × 3 × 2 × 1)

= 2002

Therefore, there are 2002 possible 5-topping pizzas that can be ordered from the pizza parlor.

To calculate the number of 5-topping pizzas possible when there are 14 different toppings available and no double-orders of toppings are allowed, we can use the formula for combinations, which is:

n C r = n! / (r! × (n-r)!)

where n is the total number of items, r is the number of items being selected, and ! denotes the factorial operation.

In this case, we have:

n = 14 (the total number of toppings)

r = 5 (the number of toppings being selected)

Plugging these values into the formula, we get:

14 C 5 = 14! / (5! × (14-5)!)

= (14 × 13 × 12 × 11 × 10) / (5 × 4 × 3 × 2 × 1)

= 2,300

To calculate the number of possible 5-topping pizzas, we need to use the combination formula since the order of the toppings doesn't matter. The formula is:

n C r = n! / (r! × (n-r)!)

where n is the total number of items to choose from, r is the number of items to choose, and "!" denotes the factorial function (i.e., the product of all positive integers up to that number).

In this case, n = 14 (the total number of toppings) and r = 5 (the number of toppings to choose).

So, the number of possible 5-topping pizzas is:

14 C 5 = 14! / (5! × (14-5)!)

= (14 × 13 × 12 × 11 × 10) / (5 × 4 × 3 × 2 × 1)

= 2,002,200

Therefore, there are 2,300 possible 5-topping pizzas that can be made with 14 different toppings and no double-orders of toppings allowed.

In order to lengthen the spring from its natural length to 0.9 feet beyond it, 4.608 feet-pounds of labor must be done.

Given data;

A force of 6 pounds is required to hold a spring stretched 0.5 feet beyond its natural length.

The force required = force in spring

6 = 0.5 * k

Where k is spring constant.

∴ k = 6/0.5 = 12 pound/feet

Energy stored in the spring = (k * 2) / 2, if the spring is stretched by a distance 'x'

Conserving energy, we get energy stored in the spring = work done in stretching the spring

∴Work done = 0.6 * (12) * (0.9)²

                     = 4.608 feet-pound

Hence, 4.608 feet-pound work is done in stretching the spring from its natural length to 0.9 feet beyond its natural length.

The population and may need to be approximated using other methods such as t-distribution or bootstrapping.

Population is a group of individuals of the same species living in the same area at the same time. It is a term used in biology, sociology and other fields of study.

Without knowing the specific characteristics of the population, it is difficult to determine the exact distribution of the sample mean of a simple random sample of size 15 drawn from that population.

However, if the population is approximately normally distributed or if the sample size is large enough (usually considered to be n > 30), the sample mean will follow a normal distribution. This is known as the Central Limit Theorem.
Hence, If the population is not normally distributed and the sample size is small, the distribution of the sample mean will depend on the specific characteristics of the population and may need to be approximated using other methods such as the t-distribution or bootstrapping.
