Step-by-step explanation: We are told that the large cistern is completely filled shown with the larger volume. To find volume, the formula is lxwxh and if you apply that to the model, the larger cistern has a volume of 24 ft cubed which means 24 is completely filled. If we calculate the volume of the smaller cistern, it is 6. The question asks us how many cubic feet will be left when the larger cistern pours enough water to completely fill up the smaller cistern (24). So we do subtraction, 24-6= 18 meaning 18 is the number that is going to get poured from the big to the small cistern to make it 24 or, completely filled. And when we subtract the 18 from 24 (because we poured 18 from the large one to the small one to make it full), we get 6. 6 is how much is left after the larger cistern poured 18 to fill up the smaller cistern.

Answer:

The total number of fruits Halston can choose is 3 + 4 + 2 = 9.

The number of ways she can choose two fruits without restrictions is 9C2 = (98)/(21) = 36.

The number of ways she can choose two fruits where both are bananas is 2C2 = 1.

Therefore, the number of ways she can choose two fruits that are not bananas is 36 - 1 = 35.

So, the probability that Halston chooses two fruits that are not bananas is:

35/36

Therefore, the probability that Halston chooses two fruits that are not bananas is 35/36.

We will use sine function, and length of the opposite side is [tex]\frac{25\sqrt{3}}{2}$[/tex] feet.

To solve for the opposite side of the right triangle, we would use the sine function. In a right triangle, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse.

In this problem, we are given that one angle of the right triangle is 60 degrees and the hypotenuse is 25 feet. Let's label the opposite side as x and the adjacent side as y. Then we can use the sine function:

[tex]$\sin 60^\circ = \frac{x}{25}$[/tex]

Simplifying the left side, we have:

[tex]$\frac{\sqrt{3}}{2} = \frac{x}{25}$[/tex]

Multiplying both sides by 25, we get:

[tex]$x = \frac{25\sqrt{3}}{2}$[/tex]

Therefore, the length of the opposite side is [tex]\frac{25\sqrt{3}}{2}$[/tex] feet.

To solve the given equation, we can start by taking the square root of both sides of the equation:

(x – 7)^2 = 36

√((x – 7)^2) = ±√36

x – 7 = ±6

Now, we can solve for x by adding 7 to both sides of the equation for each case:

x – 7 = 6 or x – 7 = -6

x = 13 or x = 1

Therefore, the values of x that satisfy the equation are x = 13 and x = 1. The other values, x = -29 and x = 42, do not satisfy the equation.

Step-by-step explanation:

The gravitational waves would have traveled through a volume of approximately 3.244 x 10⁷⁴ cubic light-years.

The space-time continuum is subject to gravitational waves, which move at the speed of light. They are caused by the acceleration of large objects that distort space-time around them, such as neutron stars or black holes.

The bending of space-time brought on by the existence of mass and energy is what Einstein's theory of general relativity refers to as gravity rather than a force.

The radius of the sphere can be determined using the formula:

R = Distance / Time

For 1.3 billion light years we have:

R = Distance / Time = 1.239 x 10²⁵ meters

Substituting the value in the volume:

V = (4/3) x π x R³ = 3.244 x 10⁷⁴ cubic light-years (approx)

Hence, the gravitational waves would have traveled through a volume of approximately 3.244 x 10⁷⁴ cubic light-years.

Expression equivalent to 5x - 4 are 5(x - 4/5), 5x - 20/5, 10x/2 - 8/2 and 3(5x/3) - 4

To create an expression equivalent to 5x - 4, we need to use arithmetic operations such as addition, subtraction, multiplication, and division, along with numbers and variables. The goal is to manipulate the numbers and variables in a way that results in the same value as 5x - 4.

Here are some examples of how we can do this:

5(x - 4/5)

In this expression, we start with x and subtract 4/5 from it. Then we multiply the result by 5. This is equivalent to distributing the 5 to x and -4/5, which gives us 5x - 4.

5x - 20/5

Here, we simply subtract 20/5 (which simplifies to 4) from 5x. This gives us 5x - 4.

(25x - 20)/5

In this expression, we start with 25x and subtract 20 from it. Then we divide the result by 5. This is equivalent to simplifying the expression to 5x - 4.

10x/2 - 8/2

This expression might look a bit different, but it's still equivalent to 5x - 4. Here, we start with 10x and divide it by 2, which gives us 5x. Then we subtract 8/2 (which simplifies to 4) from it, giving us 5x - 4.

3(5x/3) - 4

X = 61,  Angle 57 and 123

Step-by-step explanation:

If you could provide the exact question that would be great, but from the information given what we know is that the entirety of half of a circle is 180 degrees so the angle at x-4 and the angle and 2x+1 must be equal to 180 degrees.

Therefore:

x-4  +  2x+1 = 180 degrees

X = 61,    Therefore:

x-4 -->  61 -4 = 57 degrees

2x+1 ---> 2(61) +1  = 123 degrees

So:

The angles are 57 degrees for x-4 and 123 for 2x+1 .

The total balance after four years when compounded continuously is $12,615.24.

A technique of calculating interest on a loan or investment where interest is compounded an endless number of times annually is called continuous compounding. Continuous compounding is a method of growing an investment or debt over time by continually adding interest earned over a relatively brief period of time to the principal. In financial computations where interest is earned or charged continuously, such in the bond or mortgage markets, continuous compounding is frequently utilised.

The compound interest is given as:

[tex]A = Pe^{(rt)}[/tex]

Substituting the values:

[tex]A = 12000 * e^{(0.0125 * 4)}\\A = 12000 * e^{(0.05)}[/tex]

f(x) = (x+3)^2 + 5

Step-by-step explanation:

Hope this is right :)

The sum of the two functions  f(x) + g(x)  is  (x+2)/(x^2 - 9) + 11/(x^2 + 3x)

(a) To find f(x) + g(x), we simply add the two functions together:

f(x) + g(x) = (x+2)/(x^2 - 9) + 11/(x^2 + 3x)

(b) To determine the excluded values, we need to look for values of x that make the denominators of the two functions equal to zero. The denominators are:

x^2 - 9 and x^2 + 3x

Setting these equal to zero and solving for x, we get:

x^2 - 9 = 0 => x = ±3

x^2 + 3x = 0 => x(x+3) = 0 => x = 0 or x = -3

Therefore, the excluded values are x = ±3 and x = 0.

(c) To classify the type of discontinuity at each of the excluded values, we need to examine the behavior of the function as x approaches these values.

At x = ±3, the denominators of both functions become zero, which means that the function is undefined at these values. This creates a vertical asymptote, which is a type of infinite discontinuity.

At x = 0, the denominator of g(x) becomes zero, but the denominator of f(x) does not. This creates a removable discontinuity, because we can define f(0) separately to make the function continuous at this point. Specifically, we can set f(0) = 2/(-9) = -2/9 to remove the discontinuity.

To assess the reasonableness of Cameron's statement that he spent about $215 on a gaming system and video games, we can use mental math to estimate the total cost.

We know that he spent $130 on a gaming system and $80 on video games. If we round $80 up to $100 and add it to $130, we get:

$130 + $100 = $230

So based on this estimate, it seems like Cameron's statement of spending about $215 is not entirely accurate. However, it is close to the actual total cost, which is within 10% of the estimated total.

Therefore, we can say that while Cameron's statement may not be entirely precise, it is reasonably close to the actual total cost and can be considered reasonable.

The probability of rolling an even number on a single die is 1/2, or 50%. This can be calculated by considering the possible outcomes of rolling the die.

There are six possible outcomes, and three of these are even numbers (2, 4, and 6). Therefore, there is a 3/6, or 1/2, chance of rolling an even number. In terms of probability, this can be expressed as a fraction, percentage, or decimal. As a fraction, the probability of rolling an even number on a single die is 3/6, or 1/2. As a percentage, the probability of rolling an even number on a single die is 50%. As a decimal, the probability of rolling an even number on a single die is 0.5. No matter how it is expressed, the probability of rolling an even number on a single die is 1/2, or 50%.

The probability that a randomly selected car will get through the restaurant's drive-through in less than 101 seconds is  -1.3

What is normal distribution ?

Normal distribution, also known as Gaussian distribution or bell curve, is a continuous probability distribution that is commonly used in statistical analysis to model real-world phenomena. A normal distribution is characterized by its mean (μ) and standard deviation (σ), and is symmetrical around its mean. The bell-shaped curve of a normal distribution is determined by the empirical rule, also known as the 68-95-99.7 rule, which states that approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. Many natural phenomena, such as human height and weight, tend to follow a normal distribution, and this makes normal distribution a useful tool in statistical analysis and modeling.

According to the question:
(a) To find the probability that a randomly selected car will get through the restaurant's drive-through in less than 101 seconds, we need to standardize the value using the formula:

z = (x - μ) / σ

where x is the value we are interested in, μ is the mean drive-through time, σ is the standard deviation, and z is the corresponding z-score.

Plugging in the values given, we get:

z = (101 - 137.5) / 27 = -1.3

Using a standard normal distribution table or a calculator, we find that the probability of getting a z-score less than -1.35 is 0.0885. Therefore, the probability that a randomly selected car will get through the restaurant's drive-through in less than 101 seconds is:

P(X < 101) = P(Z < -1.35) = 0.0885 (rounded to four decimal places).

(b) To find the probability that a randomly selected car will spend more than 176 seconds in the restaurant's drive-through, we again need to standardize the value:

z = (176 - 137.5) / 27 = 1.42

Using a standard normal distribution table or a calculator, we find that the probability of getting a z-score greater than 1.42 is 0.0788. Therefore, the probability that a randomly selected car will spend more than 176 seconds in the restaurant's drive-through is:

P(X > 176) = P(Z > 1.42) = 0.0788 (rounded to four decimal places).

(c) To find the proportion of cars that spend between 2 and 3 minutes (120 and 180 seconds) in the restaurant's drive-through, we need to standardize the values of the lower and upper limits:

z1 = (120 - 137.5) / 27 = -0.65

z2 = (180 - 137.5) / 27 = 1.57

Using a standard normal distribution table or a calculator, we find the area between these two z-scores to be 0.6591. Therefore, the proportion of cars that spend between 2 and 3 minutes in the restaurant's drive-through is:

P(120 < X < 180) = P(-0.65 < Z < 1.57) = 0.6591 (rounded to four decimal places).

(d) To find the probability that a car spends more than 3 minutes (180 seconds) in the restaurant's drive-through, we standardize the value:

z = (180 - 137.5) / 27 = 1.57

Using a standard normal distribution table or a calculator, we find that the probability of getting a z-score greater than 1.57 is 0.0582. Since this probability is less than 0.05, it would be considered unusual for a car to spend more than 3 minutes in the restaurant's drive-through.
