The expected number is 1, that means that if you randomly pick one ball and replace it with a blue ball, then you have a greater than 50/50 chance of eliminating all the red balls.

The expected number of blue balls needed to eliminate all red balls is calculated using the formula[tex]n = (x-1)/(y-1)[/tex]. In this scenario, x = 3 (the total number of balls in the box) and y = 2 (the number of red balls). Therefore, n = (3-1)/(2-1), which equals 1. So, the expected number of blue balls needed to eliminate all red balls is 1.

To illustrate this, imagine a box with 3 balls: 2 red and 1 blue. If you randomly pick one ball and replace it with a blue ball, then you have a 50/50 chance of eliminating all the red balls. If the ball you pick is red, then you need to pick another ball and replace it with a blue ball to get rid of the remaining red ball. This means that you need a total of 2 blue balls to get rid of all the red balls. However, since the expected number is 1, that means that if you randomly pick one ball and replace it with a blue ball, then you have a greater than 50/50 chance of eliminating all the red balls.

The correct initial value problem is: y'' + (9.81/0.75) y = 0, y(0) = -0.36, y'(0) = -0.45.

Here's how you can set up the initial value problem

Let y(t) be the displacement of the mass from its spring-mass equilibrium position at time t. Then, the force acting on the mass is given by Hooke's Law:

F = -ky

where k is the spring constant.

Since the mass is at rest at its equilibrium position, the force acting on it is balanced by the force of gravity.

mg = ky_eq

where y_eq is the equilibrium position of the spring-mass system.

Substituting F = -ky into the equation and solving for k, we get:

k = mg/y_eq

Substituting k and the values given, we get:

y'' + (9.81/0.75) y = 0

where y'' is the second derivative of y with respect to time.

When the mass is displaced 36 cm upward from its spring-mass equilibrium and then given a sharp downward tap, the initial conditions are:

y(0) = -0.36 m

y'(0) = -0.45 m/s (note that the velocity is downward, so it's negative)

Therefore, the initial value problem that models this experiment is:

y'' + (9.81/0.75) y = 0

y(0) = -0.36

y'(0) = -0.45

The mass of the water is 7880.1 grams.

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass.

Mathematically -

Q = mcΔT

where -

{Q} = heat energy

{m} = mass

{c} = specific heat capacity

{ΔT} =change in temperature

Given is the water in a container changes its temperature from 12°C to 38°C, when 205 calories are transferred to it.

Specific heat capacity of water = 4.186 J/g°C

205 calories = 857720 Joules

We can write -

Q = mcΔT

857720 = m x 4.186 x (38 - 12)

857720 = 108.836 x m

m = 857720/108.836

m = 7880.1 grams

Therefore, the mass of the water is 7880.1 grams.

Step-by-step explanation:

the function

Kendal(x) = y = 90

is just a flat line (that's why people call it a flat rate). it does not matter how many hours it takes, it costs the same.

the function

Mona(x) = 10x + 70

as we know, $10 per hour, plus $70 for the material, which is the same cost no matter how many hours it takes.

the solution, when both cost the same, means again both functions are equal at that point :

90 = 10x + 70

20 = 10x

x = 20/10 = 2 hours

after 2 hours both cost the same : $90.

the graphic should look like the attached picture.

the flat line is at y = 90. that means it is a horizontal line that goes through the y gridline marker 90.

just draw the line along the y 90 gridline from left to right.

Mona's graph goes through the solution point (2, 90) and the point for x = 0 : (0, 70) because y = 10×0 + 70 = 70.

for (0, 70) you go from 0 the y-axis straight up to the gridline marker 70 and mark the point there.

for (2, 90) you go on the x-axis from 0 to the right to the gridline marker 2. from there you go straight up to the y gridline 90. and you mark the point there.

and both lines intersect at (2, 90), which is the solution.

can you see and understand it now how that works ?

The cost is $90

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

The function for Kendal(x) is:- y = 90

The function for Mona(x) :- 10x + 70

$10 per hour, plus $70 for the material

The solution, when both cost the same, means again both functions are equal at that point :

20 = 10x

x = 20/10 = 2 hours

after 2 hours both cost the same : $90.

The solution to the system of equations is x = -8, y = 9.

To solve the system of equations by elimination, we must manipulate the two equations so that when the equations are added or subtracted, one of the variables is eliminated.

One method is to multiply one or both equations by a constant, resulting in opposite coefficients for one of the variables. In this case, we can multiply the first equation by 4 and the second equation by -5, yielding the following y coefficients:

code :

(4)(5x + 4y = -4) => 20x + 16y = -16 (-5)

(4x + 4y = 4) => -20x - 20y = -20

We can now combine the two equations to eliminate y:

code :

20x + 16y = -16 \s-20x - 20y = -20 \s———————

0x - 4y = -36

When we simplify the result, we get:

code :

-4y = -36 y = 9

Now we can plug y = 9 back into one of the original equations to find x. Let's look at the first equation:

code :

5x+4y = -4 5x+4(9) = -4 5x+36 = -4 5x = -40 x = -8

If we represent the first number as "x", then the second number can be represented as "2x-3".

For example, if the first number is 5, then the second number would be 2(5)-3 = 7.

Alternatively, if the first number is 10, then the second number would be 2(10)-3 = 17.

In general, we can say that the second number is equal to twice the first number minus 3.

The matching parts of vectors a and c to find a + c. For instance, (1, -2, 4) + (2, 3, -1) = (3, 1, 3).

The equations and calculations to determine the vectors a and c's sum are as follows:

Assume that vector an is shown as (a1, a2, a3) and that vector c is shown as (c1, c2, c3).

Then, by adding each of their respective components, it is possible to determine the vectors a and c's sum, denoted as a + c:

A plus C equals (A+C1, A+C2, A+C3, etc.)

For instance, if a = (2, 3, -1) and c = (1, -2, 4), we can use the following formula to get their sum:

a + c = (2 + 1, 3 - 2, -1 + 4) = (3, 1, 3) (3, 1, 3)

Andre's number is 43.

Generally, Let's call the tens digit of Andre's number "t" and the ones digit "o".

We know that Andre can make the number in 8 different ways. This means that there are 8 different combinations of t and o that can make up the number.

One of these ways has 1 more ten than ones, which means that the number is 10 more than the sum of the digits. In other words:

t + o + 10 = 10t + o + 1

Simplifying this equation, we get:

9t = 9o + 9

Dividing both sides by 9, we get:

t = o + 1

This means that the tens digit is 1 more than the ones digit, which narrows down our possibilities.

Since the number is a 2-digit number, the tens digit must be between 1 and 9 (inclusive), and the ones digit must be between 0 and 9 (inclusive). We also know that the tens digit is 1 more than the ones digit.

Using these constraints, we can create a table of all the possible combinations of t and o that satisfy these conditions:( table attached below)

Out of these 8 numbers, only one of them can be made in a way where there is 1 more ten than ones. Looking at the table, we can see that the number is 43, since it is the only number where the tens digit is 1 more than the ones digit, and it can be made by combining the digits in a way where there is 1 more ten than ones (i.e., 3 tens and 4 ones).

b. To find g(1)-f(-3), we first need to find g(1) and f(-3) separately.

g(1) = 2(1) - 5 = -3

f(-3) = (-3)² - 3(-3) = 9 + 9 = 18

Then, we can substitute these values into the expression:

The marginal cost function is the derivative of the cost function, which is C'(a) = 50.

The marginal revenue function is the derivative of the revenue function, which is R'(a) = -0.5(3/8 - 110).

A one-sample t-test can be used to determine whether the sample mean of M=115 is a particularly improbable outcome given the population parameters.

The test's null hypothesis is that the new treatment has no impact on extraversion, in which case the population mean remains at or above 100. The alternative theory is that the new treatment has an impact on extraversion, causing the population mean to deviate from the reference value of 100.

Using the following method, we can determine the test's t-statistic:

(M - ) / (s / sqrt(n)) t

Where M denotes the sample mean, denotes the population mean, s denotes the population standard deviation, and n denotes the sample number.

By entering the numbers we have:

t = (115 - 100) / (30 / sqrt(4)) = 3.33

The measure has n-1 = 3 degrees of freedom. We can use a calculator to determine the critical t-value, which is roughly 3.182, using a two-tailed t-test with alpha = 0.05 and 3 degrees of freedom.

The sample mean is a particularly improbable result based on the population parameters for the personality test because the calculated t-value of 3.33 is higher than the critical t-value of 3.182, and we can therefore reject the null hypothesis.

The measure of arc AD by using the property that "if two chords intersect in the interior of the circle, then the measure of each angle is half the sum of the arcs intercepted by the angles and its vertical angle".

Thus, applying the above theorem:

93° = 1 /2 (arcBC + arcAD)

Here, measure of angle E is 93°.

93° = 1 / 2( 161 + AD)

93 = 161 / 2 + AD / 2

93 = 161/ 2 +  AD/2

solving further ( multiplying equation by 2 on both sides)
