can someone tell me what to write please

There were 13 small boxes shipped and 6 large boxes shipped.

Let's denote the number of small boxes as 's' and the number of large boxes as 'l'.

According to the given information, the volume of each small box is 6 cubic feet, so the total volume of all small boxes can be calculated as 6s cubic feet.

Similarly, the volume of each large box is 13 cubic feet, so the total volume of all large boxes can be calculated as 13l cubic feet.

We are also given that the combined volume of all the boxes is 156 cubic feet, so we can write the equation:

6s + 13l = 156 ...(1)

Additionally, we know that a total of 19 boxes were shipped, so we can write another equation:

s + l = 19 ...(2)

Now, we have a system of equations (equation 1 and equation 2) that we can solve simultaneously to find the values of 's' and 'l'.

To solve this system of equations, we can use substitution or elimination method. Let's use the substitution method here.

From equation 2, we can rewrite it as s = 19 - l.

Substituting this value of s into equation 1, we get:

6(19 - l) + 13l = 156

Simplifying the equation:

114 - 6l + 13l = 156

Combining like terms:

7l = 42

Dividing both sides by 7:

l = 6

Now, we can substitute this value of l back into equation 2 to find the value of s:

s + 6 = 19

s = 13

The number of small boxes shipped is 13, and the number of large boxes shipped is 6.

There were 13 small boxes shipped and 6 large boxes shipped.

The probability that the card will be a spade or a club 50%

Probability in math is referred as  how likely an event is to occur, or how likely it is that a proposition is true.

Here we have given that a card is drawn from a standard deck of 52 playing cards.

And we need to find  the probability that the card will be a spade or a club and we have to express your answer as a fraction or a decimal number rounded to four decimal places.

While we looking into the given question, we have identified the the total number of cards is 52.

And the number of spade cards = 13 and the number of club cards = 13

Therefore, the total number of spade and club cards

=> 13 + 13

=> 26

Therefore, the probability of getting a spade or  a club from a single draw is,

=> 26/52

When we simplified this one, then we get,

=> 0.5

The value of x is 29 cm.

To find the value of x, we can use the formula for the volume of a prism, which is V = A * h, where V is the volume, A is the area of the cross-section, and h is the height. In this case, we are given that the volume is 2465 cm^3 and the area of the cross-section is 85 cm^2. We need to solve for the height, h.

Using the formula, we have 2465 = 85 * h. To solve for h, we divide both sides of the equation by 85, giving us h = 2465 / 85 = 29 cm.

Step-by-step explanation:

Use the equation x = -b/2a => x = -12/6 = -2.

The expression is equivalent to "\(z^4 * (z + 6)^2 + (z + 6)\)".

To clarify, I understand the expression as: "z * (z + 6) * z * (z + 6) * z + (z + 6)". Let's break down the expression and simplify it step by step:

Distribute the multiplication:

z * (z + 6) * z * (z + 6) * z + (z + 6)

becomes

z * z * z * (z + 6) * (z + 6) * z + (z + 6)

Combine like terms:

z * z * z simplifies to \(z^3\)

(z + 6) * (z + 6) simplifies to (z + 6)^2

The expression now becomes:

\(z^3 * (z + 6)^2 * z + (z + 6)\)

Multiply \(z^3\) and z:

 \(z^3 * z\) simplifies to \(z^4\)

The expression becomes:

  \(z^4 * (z + 6)^2 + (z + 6)\)

So, an equivalent expression to "z (z + 6)z (z + 6)z + (z + 6)" is "\(z^4 * (z + 6)^2 + (z + 6)\)".

Uh where are the other expressions?

Step-by-step explanation:

Country B is more efficient than Country A when it comes to producing cars and tanks.

Country A takes twice as long to produce a car (30 minutes) than Country B (12 minutes). However, Country A takes 20 minutes to produce a tank while Country B takes 10 minutes, cutting the amount of time in half.

We can measure the efficiency of each country by calculating the number of cars and tanks each country can produce in an hour. We can do this using the following formula:

Cars per hour = (60 minutes/minutes to produce car)

Tanks per hour = (60 minutes/minutes to produce tank)

For Country A, the number of cars produced in an hour is (60 minutes/30 minutes) = 2 cars per hour and the number of tanks produced in an hour is (60 minutes/20 minutes) = 3 tanks per hour.

For Country B, the number of cars produced in an hour is (60 minutes/12 minutes) = 5 cars per hour and the number of tanks produced in an hour is (60 minutes/10 minutes) = 6 tanks per hour.

Therefore, Country B is more efficient than Country A when it comes to producing cars and tanks.

Quantity of gasoline that Jonathan use cutting the grass is 24,000 milliliters

To calculate the amount of gasoline Jonathan used cutting the grass, we need to find the difference between the initial amount of gasoline and the amount of gasoline left in the tank after mowing the grass.

The initial amount of gasoline is 45 liters, and the amount of gasoline left in the tank is 21 liters

So, the amount of gasoline Jonathan used is

45 - 21 = 24 liters

However, we are asked to express the amount of gasoline used in milliliters. To do this, we can use a conversion factor that relates liters to milliliters.

There are 1000 milliliters in one liter, so we can multiply the amount of gasoline used in liters by 1000 to get the equivalent amount in milliliters.

Therefore, the amount of gasoline Jonathan used cutting the grass is

24 liters x 1000 ml/liter = 24,000 milliliters

The maximum height of the projectile is 56.53 meters.

The height of a projectile at time t is represented by the function h (t)= −4.9 t² +18t + 40, where h(t) is the height in meters and t is the time in seconds.

This is a quadratic function of the form h(t) = at² + bt + c, where a = -4.9, b = 18, and c = 40.

To find the maximum height of the projectile, we need to find the vertex of the parabolic graph of the function h(t).

The vertex of the parabola is at the point (t, h(t)) where t = -b/2a. Substituting the values of a and b, we get t = -18/(2(-4.9)) = 1.8367 seconds.

To find the maximum height, we need to substitute t = 1.8367 seconds into the function h(t). h(1.8367) = -4.9(1.8367)^2 + 18(1.8367) + 40 = 56.53 meters.

Answer:

A

Step-by-step explanation:

Geometry

The answer is A, due to 3 and 2 being vertical.

The height of a rider on the London Eye Ferris wheel in London can be modeled by the function h(t) = A * cos(B * t), where t represents time in minutes. The Ferris wheel stands 135 meters tall with a diameter of 120 meters. It takes half an hour (30 minutes) to complete one revolution.

1. At t = 0 minutes, the rider is not at the bottom of the wheel but at the midpoint of the wheel's diameter, so the rider's height is equal to the radius of the wheel, which is half of its diameter. Therefore, the rider's height at t = 0 minutes is 120/2 = 60 meters.

2. To determine the time it takes for the rider to reach the top, we need to find the period of the cosine function. The period (T) is the time it takes for one complete cycle of the function. In this case, the period is equal to the time it takes for the Ferris wheel to make a full revolution, which is 30 minutes. So, the rider reaches the top after half of the period, which is T/2 = 30/2 = 15 minutes. At that time, the rider's height is equal to the sum of the radius of the wheel and its height, which is 60 + 135 = 195 meters.

3. The period of the cosine function is T = 30 minutes.

4. The vertical shift of the function represents the average height of the rider throughout one complete cycle. In this case, the average height is the sum of the radius and the height of the Ferris wheel divided by 2, which is (60 + 135)/2 = 97.5 meters. Therefore, the vertical shift of the function is 97.5 meters. The amplitude of the function is half of the vertical distance between the maximum and minimum values, which is (135 - 60)/2 = 37.5 meters.

5. The equation of the cosine function is h(t) = 97.5 + 37.5 * cos((2π/30) * t). To find the rider's height at t = 21 minutes, we substitute t = 21 into the equation: h(21) = 97.5 + 37.5 * cos((2π/30) * 21) ≈ 185.11 meters.

In summary, the rider's height at t = 0 minutes is 60 meters. It takes 15 minutes for the rider to reach the top, at which point their height is 195 meters. The period of the function is 30 minutes. The vertical shift is 97.5 meters, and the amplitude is 37.5 meters. Using the cosine function, the rider's height at t = 21 minutes is approximately 185.11 meters.

What is confidence level?

A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. The 95% confidence level is the most popular, however other levels, such as 90% or 99%, are occasionally used when computing confidence intervals.

Given,

Here at 95% CI, the z value is 1.96

a) sample n = 200, p = 0.52

Now, we find the margin of error and we get

Margin of error = z×√(p(1-p)/n)

Now, substitute values of p, n, and z and we get

= 1.96×√(0.52(1-0.52)/200)

= 0.069

b) n = 800 , p = 0.52

Margin of error = z×√(p(1-p)/n)

Now, we substitute values of n, p, and z and we get

= 1.96×√(0.52(1-0.52)/800)

= 0.035

c) n = 800 , p = 0.1

First,  we find the margin of error and we get

Margin of error = z×√(p(1-p)/n)

Now, we substitute values and we get

= 1.96×√(0.1(1-0.1)/800)

= 0.021

d) n = 800 , p = 0.7

Margin of error = z×√(p(1-p)/n)

Now, we substitute values and we get

= 1.96×√(0.7(1-0.7)/800)

= 0.032

e) n = 1200 , p = 0.60

First, we find the margin of error and we get

Margin of error = z×√(p(1-p)/n)

After substituting values we get

= 1.96×√(0.6(1-0.6)/1200)

= 0.028

Hence,

The margin of error is:

a) 0.069

b) 0.035

Answer:

The mean of the random variable Y is (17/2) kilowatt hours.

Step-by-step explanation:

To find the expected value of Y, we can use the formula provided in the theorem:

E(Y) = E(51X^2 + 40X)

Using linearity of expectation, we can break this down into two separate expected values:

E(Y) = 51E(X^2) + 40E(X)

The given probability density function is, f(x) = (1/4)x, 0 ≤ x ≤ 2.

The expected value of a continuous random variable is calculated using the formula shown below, where E(x) is the expected value of x, and f(x) is the probability density function of x.

E(x) = ∫xf(x)dx

The expected value of the random variable X can be calculated as follows:

E(X) = ∫0² (1/4)x dx = (1/8) [x²]₀² = 1

E(X²) = ∫0² (1/4)x² dx = (1/12) [x³]₀² = (1/6)

Now we can substitute these values into our original equation:

E(Y) = E(51X² + 40X) = 51E(X²) + 40E(X) = 51(1/6) + 40(1) = (17/2) kilowatt hours.

Therefore, the mean of the random variable Y is (17/2) kilowatt hours.
