Answer:

8 cherries

Step-by-step explanation:

Let r represent the number of cherries Rua was given

24 - r - 5 = 1.5r - 1

Simplify and solve for r.

19 - r = 1.5r - 1

-2.5r = -20

r = 8

So Liz gave Rua 8 cherries at the start.

Inferences can be made for these types of plants, and the conclusion can be drawn that the fertilizer will help these types of plants grow taller.

A scientific experiment known as a randomised controlled trial (RCT) includes randomly allocating participants or subjects to various groups, often a treatment group and a control group. The intervention or therapy under test is administered to the treatment group while being withheld from the control group. Researchers can isolate the impact of the intervention on the desired outcome and reduce the impacts of confounding variables by randomly allocating individuals to these groups. To evaluate the effectiveness of therapies and treatments, RCTs are often employed in the medical, psychological, and other domains.

In the given experiment, the fertiliser appeared to be helpful in boosting plant development for this specific type of seedling since the plants that got it grew noticeably taller than the ones that did not.

Hence, option 4 is correct.

According to the solution we have come to find that, The equation of the circle with radius 8 and center (-2,9) is [tex](x + 2)^2 + (y - 9)^2 = 64.[/tex]

What is radius?

Radius is a straight line segment that joins the center of a circle to any point on its circumference. It is half of the diameter of the circle. The length of the radius is denoted by the letter "r".

The equation of a circle with center (a,b) and radius r is given by:

[tex](x - a)^2 + (y - b)^2 = r^2[/tex]

Substituting the given values, we have:

[tex](x - (-2))^2 + (y - 9)^2 = 8^2[/tex]

The probability that the part can be assembled in 7 minutes or less is 0.2592.

To solve the problem, we need to use the cumulative distribution function (CDF) of the exponential distribution. The CDF gives the probability that the random variable X (in this case, the time required to assemble the part) is less than or equal to a certain value x.

The CDF of the exponential distribution is given by:

F(x) = [tex]1 - e^{(-λx)}[/tex]

where λ is the rate parameter of the exponential distribution, which is equal to 1/mean. In this case, the mean is 14 minutes, so λ = 1/14.

To find the probability that the part can be assembled in 7 minutes or less, we plug x = 7 and λ = 1/14 into the CDF formula: F(7) = [tex]1 - e^{(-(1/14)*7)} \approx 0.2592[/tex]

So, there is a chance of about 25.92% (rounded to four decimal places) that the part can be assembled in 7 minutes or less.

The distance around the equator is 40,820 km, when the Earth's diameter is approximately 13000km. The distance around the Earth is the circumference.

The Earth is nearly a perfect sphere, but not quite. Astronomers utilized the diameter of the Earth as their primary measuring tool to gauge the extent of the solar system during the 18th and 19th centuries. Today's astronomers typically don't need to be aware of the Earth's size for their regular research tasks.

Nonetheless, the Earth's diameter continues to be the starting point for us, the inhabitants of this planet, in our quest to comprehend the cosmic distance scale. Eratosthenes measured the polar radius, and the number he obtained using the conversion of 0.15 km/stadium sits halfway between the polar and equatorial values.

the price per ticket that will give maximum revenue is $6.5, and the maximum revenue in dollars per ticket is $2.925.

As given,If club members charge $3 admission to a classic car show, 1000 people will attend, and for each $1 increase in price, 100 fewer people will attend.

We need to determine the price that will give the maximum revenue for the show and the maximum revenue in dollars per ticket.

Let the number of $1 increases in price be x. Then the number of people attending will be (1000 - 100x), and the price per ticket will be $(3 + x).The total revenue will be:

Revenue = Price × Quantity= $(3 + x) × (1000 - 100x)= $3000 - $100(x^2 + 7x)

The revenue function is quadratic, with the coefficient of the x^2 term being negative. Hence the graph of the function is a parabola which opens downwards, with a maximum at the vertex of the parabola.To find the value of x that will give maximum revenue, we first find the x-coordinate of the vertex.

For a quadratic function of the form f(x) = ax^2 + bx + c, the x-coordinate of the vertex is given by x = -b / (2a).In this case, a = -100, and b = -100(7) = -700. Therefore, the x-coordinate of the vertex is:x = -b / (2a)= 7/2= 3.5

Therefore, the value of x that will give maximum revenue is 3.5. Substituting this value of x in the revenue function, we get:Revenue = $3000 - $100(x^2 + 7x)= $3000 - $100(3.5^2 + 7(3.5))= $2925

The rectangular prism with a fixed surface area of 282 square units and maximum volume has dimensions of 9 by 9 by 14 units.

To find the dimensions of the rectangular prism with a fixed surface area of 282 square units and maximum volume, we need to use the fact that the volume of a rectangular prism is given by V = lwh and the surface area is given by SA = 2lw + 2lh + 2wh. Since we want to maximize the volume, we can use the surface area formula to solve for one of the dimensions in terms of the other two, and then substitute into the volume formula to obtain a function of two variables.

We can then take the derivative of this function and set it equal to zero to find the maximum volume. Solving this equation, we obtain l = w = 9 and h = 14, which gives the desired dimensions.

Therefore, the rectangular prism with a fixed surface area of 282 square units and maximum volume has dimensions of 9 by 9 by 14 units.

What is Semicircle?

If a circle is cut into half along the diameter, that half-circle is called a semicircle. The two halves are of equal measure. A semicircle can also be referred to as a half-disk and it represents a circular paper plate folded into halves. There is one line of symmetry in the semicircle that is considered as the reflection symmetry. Since the semicircle is the half of a circle which is 360°, hence the arc of the semicircle always measures 180°.

To find out how much Diana paid, we need to first calculate the total cost of the pizza, the chicken wings, the salad, the drinks, and the tip, and then divide that total by 2, since Diana is paying for half.

The total cost of the pizza, chicken wings, salad, and drinks is:

$13.02 (pizza) + $12.99 (chicken wings) + $6.25 (salad) + $3.25 (Diana's drink) + $3.25 (Carrie's drink) = $38.76

Adding the tip of $10.00 to this total gives:

$38.76 + $10.00 = $48.76

Half of this total is:

$48.76 / 2 = $24.38

Therefore, Diana paid $24.38 for her food, half the cost of the pizza, and half the tip.

Diana paid $19.65, which includes $9.02 for her share of the pizza, $5.00 for her share of the tip, $12.99 for chicken wings and $3.25 for a drink. Below is the working on the sketchpad.What is shown on the sketchpad?It is shown on the sketchpad below how Diana paid for her lunch at the restaurant.

The items that she paid for are indicated in the table below the sketchpad.What is the calculation for the amount Diana paid for lunch?Diana's share of the pizza is half of $13.02, which is $6.51. Adding $6.51 to the cost of the chicken wings and a drink gives a total of $22.75 for the cost of the lunch.

After adding the tip to the total cost of the lunch, we have $32.75 ($22.75 + $10.00 tip). To find the amount Diana paid, we need to find half of the total cost of the lunch and half of the tip.The following calculation shows the amount Diana paid:Her share of the cost of the lunch was $11.37 (($6.51 + $12.99 + $3.25)/2).Her share of the tip was $5.00/2, which is $2.50.The amount Diana paid for her food, plus her share of the cost of the pizza and tip is therefore $13.87 ($11.37 + $2.50).

The total possible outcomes are 36 and the probability of rolling a 5 and a 6 is 2.78 approximately.

What is dice?

Dice are small objects with different numbers of dots or pips on each side used in games of chance or strategy. Most commonly, dice are cubes with each of the six faces marked with a different number of pips from one to six. When rolled, the number that appears on the top face of the die is used to determine the outcome of the game or the action of the player.

Dice are used in a wide variety of games, including board games, tabletop games, role-playing games, and gambling games. They can also be used for randomization in decision-making or statistical analysis. Some games use dice with more or less than six sides, with various shapes and markings, or even electronic versions that simulate rolling.

When rolling two six-sided dice, the total number of possible outcomes is 6 x 6 = 36, as there are 6 possible outcomes for each die.

To determine the probability of rolling a 5 and a 6, we first need to determine the number of ways this outcome can occur. There is only one way to roll a 5 and a 6, which is to have one die show a 5 and the other die show a 6.

So, the probability of rolling a 5 and a 6 is

P(rolling a 5 and a 6) = number of ways to roll a 5 and a 6 / total number of possible outcomes

= 1 / 36

Therefore, the probability of rolling a 5 and a 6 is 1/36, or approximately 0.0278, or about 2.78%.

79 hours will it take for one person to harvest the entire strawberry patch.

The same property is expressed using a unit conversion but in a distinct unit of measurement. For instance, time can be stated in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other length unit instead of miles.

Finding the strawberry patch's area in square meters and dividing it by the amount that one person can harvest in an hour will give us the total number of hours needed to solve this issue.

The strawberry patch's measurements must first be changed from decameters (dam) to meters.

1 decameter (dam) = 10 meter

Strawberry patch length in meters = 1.7 dam * 10 m/dam = 17 m.

The strawberry patch width in meters = 1.4 dam x 10 m/dam = 14 m.

The strawberry patch's area is therefore:

Area of strawberry patch = length × width = 17 m × 14 m = 238 m²

We must now determine how long it will take one individual to pick 3 m² of strawberries, in hours. We can calculate this by dividing the patch's overall area by the area that a single individual can select in an hour:

= a number of hours needed to harvest the complete patch.

The total harvesting time is  = 79.33 hours nearly equal to 79

Therefore, it would take one person 79 hours to gather the complete strawberry patch.

This value of x doesn't satisfy the Equation we set up earlier (59 + 2x = 360). So, we must conclude that this value of x is incorrect, and the value we found earlier (x = 150.5) is the correct one.

Let's start with the given information: we have two arc measures and an angle measure. We know that the sum of the arc measures is equal to the total circumference of the circle, which is 360 degrees. So, we can set up an equation:

59 + 2x = 360

Solving for x, we get:

2x = 301

x = 150.5

So, the value of x that makes one arc measure 2x and the other arc measure 59, and the angle measure 15, is 150.5.

Now, let's think about why this makes sense. The sum of the arc measures is equal to the total circumference of the circle, which means that the angle formed by those two arcs must be half of the central angle that intercepts them. In other words, the angle formed by the 59-degree arc and the 2x-degree arc is (59 + 2x)/2. We also know that the angle formed by the 15-degree angle and the same arc is equal to half of the angle formed by the two arcs. So:

(59 + 2x)/2 = (180 - 15)/2

59 + 2x = 165

2x = 106

x = 53

However, this value of x doesn't satisfy the equation we set up earlier (59 + 2x = 360). So, we must conclude that this value of x is incorrect, and the value we found earlier (x = 150.5) is the correct one.
