the mean is 6 because you have to add all the numbers and divide by 5

The answer is 6.

Explanation:
Since the question is asking for the number of suspensions, we'll only look at the left part of the chart.
The formula for mean is all the numbers added up in the set divided by the amount of numbers.
So, in this problem, we add up 4,5,6,7 and 8 which equals 30, and divide by 5 to get 6.

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?

Mel: (2, 50) and (5, 35)

Victor: (1, 60) and (4, 50)

Mel’s rate of change is____.That means that her height in the air decreases _____ feet every second.

Victor’s rate of change is _____ . That means that his height in the air decreases _____ feet every second.

Answers

The first thing you should do for this case is to find both slopes by applying the following equation:
 m = ((y2) - (y1)) / ((x2) - (x1))
 Mel: (2, 50) and (5, 35)
 m1 = ((35) - (50)) / ((5) - (2))
 m1 = -5 feet / s
 Victor: (1, 60) and (4, 50)
 m2 = ((50) - (60)) / ((4) - (1))
 m2 = -3.333333333 feet / s
 
 answer:
 Mel was descending at a faster rate
 Mel's rate of change is negative. That means that your height in the air decreases 5 feet every second.
 Victor's rate of change is negative. That means that his height in the air decreases 3.33 feet every second.

The height of Mel in the air is decreasing at a faster rate than victor's height in the air.

Mel's rate of change is -5 feet per second. That means that her height in the air decreases 5 feet every second. Victor's rate of change is -3.33 feet per second. That means that his height in air decreases 3.33 feet every second.

Given information:

Mel slides down water-slide A and Victor slides down water-slide B.

After 1 second, height achieved by [tex]\rm{Mel}= 50\; \text{Ft}[/tex]

After 5 seconds, the height remained is 35 feet.

In another case,

The height achieved by Victor after 1 second is 60 feet.The height remained after 4 second is 50 feet.

Now, the expression is used for evaluating the slope of the equation are formulated below:

[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

Where, [tex]m[/tex] is the slope and [tex]x[/tex] and [tex]y[/tex] are respective coordinates.

Hence, for Mel's case, apply the formula of slope and solve it further:

[tex]\begin{aligned}m_1&=\dfrac{35-50}{5-2} \\m_1&=-5 \end{aligned}[/tex]

So, the rate of change of Mel's height is 5 feet per second.

And for victor's case, slope will be:

[tex]m_2=\dfrac{50-60}{4-1} \\\\m_2=-3.33[/tex]

The rate of change of victor's height is 3.33 feet per second.

Mel's rate of change is -5 feet per second. That means that her height in the air decreases 5 feet every second.Victor's rate of change is -3.33 feet per second. That means that his height in air decreases 3.33 feet every second.

Which expression is equivalent to 15x+50

Answers

Final answer:

The equivalent expression to 15x+50, by factoring out the greatest common divisor, is 5(3x+10).

Explanation:

The question is asking for an equivalent expression to the linear algebraic expression 15x+50. By examining the coefficient and constant term, we note that both terms are divisible by 5. Therefore, we can factor out 5 to simplify the expression. The steps for simplification are as follows:

Find the greatest common divisor (GCD) of the coefficients, which in this case is 5.

Divide each term by the GCD.

Express the factored form using the distributive property.

By applying these steps:

The GCD of 15 and 50 is 5.

Dividing each term by 5 gives us 3x + 10.

Thus, we can write the expression as 5(3x + 10), which is equivalent to the original expression 15x + 50.

What is the y-intercept of the continuous function in the table?

Answers

Final answer:

The y-intercept of a function is where the graph crosses the y-axis, represented by 'b' in the equation y = mx + b. If a table doesn't show x as zero, one can use the line of best fit by inserting the median x and y values and the slope into the formula b = y - mx to calculate the y-intercept.

Explanation:

The y-intercept of a continuous function can be understood as the point where the function's graph crosses the y-axis. It is typically represented by the variable b in the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. In the context of the problem provided, if the student is examining a table of values representing a linear relationship, they should look for the value of y when x equals zero to determine the y-intercept directly.

However, if the data does not include an x-value of zero, they could use the line of best fit to calculate the y-intercept by plugging the median x and y values, along with the determined slope, into the formula b = y - mx, where y and x are the medians. For example, if given a slope (m) of 0.09, sum of median x values as 1264, and sum of median y values as 219.5, the y-intercept (b) would be calculated as b = 219.5 - 0.09(1264), which simplifies to approximately 35.25.

This calculation would be necessary if the student is working with data that does not directly provide a scenario where x = 0, such as exam scores or years in a dataset stating from year 1. It's important to note that in some real-world applications, a y-intercept may not be meaningful if the x-value cannot be zero, like in the case of time-based data where the year 0 does not exist.

The y-intercept of the continuous function is (-2). This means that the graph of the function intersects the y-axis at the point (0,-2).

The y-intercept of a continuous function represents the point where the graph of the function intersects the y-axis. In other words, it is the value of y when x is equal to zero.

Looking at the given points:

(0,-6), (-2, 0), (-6, 0), (0,-2), and 0

We can determine the y-intercepts by identifying the points where x is equal to zero.

Let's go through the points one by one:

1. (0,-6): This point does not have a y-intercept because the x-coordinate is not zero.

2. (-2, 0): This point also does not have a y-intercept because the x-coordinate is not zero.

3. (-6, 0): Again, this point does not have a y-intercept because the x-coordinate is not zero.

4. (0,-2): Finally, this point does have a y-intercept because the x-coordinate is zero. Therefore, the y-intercept is -2.

5. 0: This is not a point, but simply the value of zero. It does not have a y-intercept because it does not represent a point on the graph.

To summarize, the y-intercept of the continuous function is (-2). This means that the graph of the function intersects the y-axis at the point (0,-2).

The good estimate of the volume of the cone is 56.70 cubic inches whose radius is 1.9 inches and height of the wooden cone is 15 inches.

What is a cone?

It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.

Yadira made a wooden cone with a radius of 1.9 inches and a height of 15 inches therefore,

The radius of the wooden cone r = 1.9 inches

The height of the wooden cone h = 15 inches

We know the volume of a cone is given by:

[tex]\rm V = \pi r^2 \frac{h}{3}[/tex]

Put the values of the r and h, we get:

   [tex]\rm V = \pi( 1.9^2) \frac{15}{3}[/tex]

V = 3.61×5×π

V = 56.70 cubic inches

Thus, the good estimate of the volume of the cone is 56.70 cubic inches whose radius is 1.9 inches and height of the wooden cone is 15 inches.

dining room furniture with a cash price of $1,900 at $100.00 down and $90.00 per month for 24 months a. $ b. $ c.

Answers

The total cost is $2,260.

The question involves calculating the total cost of purchasing dining room furniture with an initial down payment and subsequent monthly payments. First, we account for the down payment: $1,900 (cash price) - $100 (down payment) = $1,800 remaining balance. This balance will be paid over 24 months at $90 per month, thus 24 * $90 = $2,160. The total cost of the furniture, including the down payment, would then be the sum of the down payment and the total of the monthly payments: $100 + $2,160 = $2,260.

The total cost of the dining room furniture with this payment plan is $2,260.00.

The total cost for the dining room furniture with the given payment plan.

1. Down Payment: $100.00

2. Monthly Installments: $90.00 for 24 months

Calculate the total cost of the furniture before any payments are made:

[tex]\[ \text{Cash Price} = \$1,900 \][/tex]

The total amount paid through monthly installments:

[tex]\[ \text{Monthly Installment} = \$90.00 \times 24 \text{ months} = \$2,160.00 \][/tex]

Finally, let's add the down payment to the total amount paid through installments to find the overall cost:

[tex]\[ \text{Total Cost} = \$100.00 + \$2,160.00 = \$2,260.00 \][/tex]

When solving this system of equations by elimination, which could be the resulting equation when a variable has been eliminated?

Answers

-3x = -3 because you would multiply one of the equations by -1 to eliminate y.

When using elimination to solve the system of equations, subtracting the first equation from the second eliminates the y variable, resulting in the equation 3x = 3, which simplifies to x = 1.

When solving the system of equations by elimination, we align the equations vertically and subtract or add them to eliminate one of the variables. Let's consider the given system:

3x - y = 7
6x - y = 10

By subtracting the first equation from the second, we eliminate variable y. The subtraction works as follows:

(6x - y) - (3x - y) = (10) - (7)

Which simplifies to:

3x = 3

From this resulting equation, we can easily solve for x:

x = 3 / 3
x = 1

This is the first part of the solution. After finding the value of x, we substitute back into either of the original equations to solve for y.
