Step-by-step explanation:
since the roller coaster takes always 8 people at a time, this problem is simply to find how often 8 fits into 346 and how many people are remaining (when we cannot fill all 8 places anymore at the end).
that is what division is for.
346 / 8 = 43 and remainder 2
as 8×43 = 344, plus 2 is then 346.
so, the remainder (2 people) will be on the last ride.
To find the number of people on the last ride of the roller coaster, divide the total number of people waiting in line by the number of people the roller coaster can fit at a time.
Explanation:To find the number of people on the last ride of the roller coaster, we need to divide the total number of people waiting in line by the number of people the roller coaster can fit at a time. In this case, we have 346 people waiting and the roller coaster can fit 8 people at a time. Dividing 346 by 8 gives us 43 with a remainder of 2. This means that there will be 43 full rides, and on the last ride, there will be 2 people left.

What is a Rectangle ?A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.
Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.
The rectangle's characteristics are listed below:
There are four vertices and four sides.Every vertex has an angle of 90 degrees.Equal and parallel sides are on the opposing sides.Intersect each other diagonallyThe perimeter is equal to double the length plus width of the object.the product of its length and width determines its area.It has four right angles and is a parallelogram.All inner angles added together equal 360 degrees.Dimension of the yard is
width = 40 ft
length = 53ft
Dimension of the yard without the walkway is
Width =40 - 4*2 = 40 - 8 = 32 ft
Length = 53 - 4*2 = 53 - 8 = 45 ft
Area of the yard = Width * Length = 40 * 53 = 2120 sq. ft
Area of the yard wtihout the walk = 32 * 45 = 1440 sq. ft

which of the three methods of assigning probabilities is used when we are dealing with sampling (as a method of determining probabilities)? no need to explain.
Random sampling methods of assigning probabilities is used when we are dealing with sampling.
Random sampling is a method of assigning probabilities used when dealing with samples of a population. It involves randomly selecting a sample from the population and then using that sample to estimate the probabilities of different outcomes. This is done by calculating the proportion of the sample that falls into each category. For example, if you are trying to determine the probability of a certain outcome, you would randomly select a sample from the population and then count how many of the individuals in the sample fall into that category. The probability of the outcome would then be calculated by dividing the number of individuals in that category by the total number of individuals in the sample.

an agriculturalist working with australian pine trees wanted to investigate the relationship between the age and the height of the australian pine. a random sample of australian pine trees was selected, and the age, in years, and the height, in meters, was recorded for each tree in the sample. based on the recorded data, the agriculturalist created the following regression equation to predict the height, in meters, of the australian pine based on the age, in years, of the tree. Predicted height = 0.29 + 0.48(age) Which of the following is the best interpretation of the slope of the regression line?
The height increases by 0.48 meters each year.
The available regression equation is: Predict height= 0.29 + 0.48 (age).
Here, the predict height is dependent variable and the age is in-dependent variable.
Intercept = 0.29
Slope = 0.48
The given regression equation indicates the y on x model and the intercept coefficients of the regression equation is 0.29 and the slope is 0.48.
The height increases, an average, by 0.48 m per year.
Because co-efficient of slope variable indicate the positive sign and we increase 1 year in age then automatically height increased is 0.48 m.
The height increases, on average, by 0.48 meter each year.

The equation of the line is y = -3x + 2.
What is the slope of a line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are represented by Δy and Δx, respectively.
As a result, m = change in y/change in x = Δy/Δx is the formula for the change in y-coordinate with respect to the change in x-coordinate.
where "m" represents a line's slope.
Given that, the line passes through the point (-1,5) with slope of -3.
The equation of line passes through (x₁, y₁) with slope m is
y - y₁ = m(x - x₁)
Putting x₁ = -1, y₁ = 5 and m = -3.
y - 5 = -3(x - (-1))
y - 5 = -3x - 3

Step-by-step explanation:
The length of the side of a triangle must be less than the sum of the lengths of the other two sides of a triangle.
Therefore:
12+14>x
x<26
However, the following must also be true:
x+12>14 (The sum of x and 14 will always be greater than 12 because 14>12, so we don’t need to include that in the inequality)
So, x>2.
This means that the answer is 2<x<26

Determine the Input
A number went into this machine and 50 came out.
What number went in?
To determine the input number, we can use the following steps:
Calculate the change in the input number as a percentage of the input number. In this case, the input number decreased by 15%, so the change is -0.15 * input number.
Add the change to the output number to find the input number. In this case, the output number is 50, so the input number is 50 + (-0.15 * input number).
Solve for the input number. In this case, we can solve for the input number by rearranging the equation and solving for x:
input number = 50 / (1 - 0.15)
input number = 50 / 0.85
input number = 58.82
Therefore, the input number is 58.82.
Note that this process can also be used to determine the output number given the input number and the percentage change. For example, if the input number is 100 and it increases by 85%, the output number would be:
output number = 100 * (1 + 0.85)
output number = 100 * 1.85
output number = 185
Answer:
[tex]x \times \frac{85}{100} \times \frac{185}{100} = 50[/tex]

The probability sum of the dice is 2/11.
Let A be the event that the sum of dots is 5, then
A={(1,4), (2,3), (3,2), (4,1)}
n(A)=4
And, B is the event that one die shows a "one"
B={(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (3,1), (4,1), (5,1), (6,1)}
n(B)=11
The Event that some of the dots are five and one of the die shows "one".
A intersection B = {(1,4), (4,1)}
Since n(A) = 36 (thirty-six possible samples of two dice)
P(A)=4/36
P(B)=11/36
P(A intersection B)=2/36

Lucy wants to plant 218 flowers in her garden. If there are 32 flowers in a box, how many boxes of flowers will Lucy need to order?
Answer:
Step-by-step explanation:
She could order 7 boxes. if each box has 32 flowers, then you would multiply 6 by 32 which is 192. If you subtract 218 from 192 you get 26. meaning that if she orders 6 boxes of 32 flowers then she would only have 192 flowers and there would be 26 flowers remaining, so then it's better for her to order 7 boxes it's better to have more than what she wants instead of having less than what she wants... that way she is able to plant 218 flowers even if there are some left.
