Answer:36

Step-by-step explanation: 6 sided dice = 6 possible outcomes

6×6=36

The required number of outcomes is 36 after rolling all six dice. Option B is correct.

Jane has to roll a set of six standard dice and record the results of each
trial. She wonders how many different outcomes are possible after rolling all six dice. the total number of possible outcomes for each trial to be determined.

Probability can be defined as the ratio of favorable outcomes to the total number of events for a system of the certain events.

For 1 dice, sample space = { 1  2  3  4  5  6}
total possible outcome = 6
Now 6 dice roll at once and the total outcome = 6 * 6
                                                                                = 36
Meanwhile, Jane has a total of 36 outcomes.

Thus, the required number of outcomes is 36 after rolling all six dice. Option B is correct.

Answer:

Sofia will be 19 years old

Step-by-step explanation:

First:

What know that David is 30 right now.

David=30

We also know that David is 7 years older than Mark, meaning that David-7=Mark

30-7=23        -Mark

And last we know that Mark is 4 years older than Sofia So we would do 23-4 to get Sofia age,

23-4=19        -Sofia

So in conclusion...

SOFIA: 19  

MARK: 23

DAVID: 30

Step-by-step explanation:

Answer:

y = -3x + 5

Step-by-step explanation:

Since the y-intercept occurs at the point (0,5), you can use that and the point slope equation to find the equation.

This looks like y - 5 = -3 (x - 0);

Solving for y, you get y = -3x + 5;

To graph this equation you would put one point at (0,5), then use the slope to count down three and to the left one to find other points, or you could just plug in numbers for x to find their corresponding y values and plot it like that.

Hopefully this helps- let me know if you have any questions!

Step-by-step explanation:

2+3+6+5 is 16 and since there are 4 numbers 16/4 is 4

Answer:

4

Step-by-step explanation:

To find average you must add up all of the numbers and then divide by the amount of numbers there are

2+3+6+5= 16

there are 4 numbers, so you do 16/4

16/4 = 4

Answer:

Length of the rectangle = 25 ft

Width of the rectangle = 5 ft

Step-by-step explanation:

Ratio of the width to the length is 1:5

So, let

Width = x

and length = 5x

Area of the rectangle = 125

[tex]x \times 5x = 125 \\ \\ 5 {x}^{2} = 125 \\ \\ {x}^{2} = \frac{125}{5} \\ \\ {x}^{2} = 25 \\ \\ x = \sqrt{25} \\ \\ x = 5 \: ft \\ \\ 5x = 5 \times 5 = 25 \: ft[/tex]

Length of the rectangle = 25 ft

Width of the rectangle = 5 ft

The length and the width of the rectangle are 25 ft and 5 ft respectively.

The area of a rectangle can be found by using the following formula:

Area = length * width

Let the constant be x, therefore the length is 5x and the width is x.

Area = length * width

125 = 5x*x

⇒125 = 5x²

⇒x² = 25

⇒x = √25

⇒x = 5

We can substitute the value of x to find the length and the width:

Length = 5x = 5*5 = 25 ft

Width = x = 5 ft

Thus, we have found the length and width of the rectangle to be 25 ft and 5 ft.

Answer:

Step-by-step explanation:

30/5=6

Answer:

It already is rounded to the nearest percent, 60.

Step-by-step explanation:

Answer (assuming it can be in slope-intercept form):

[tex]y =2x[/tex]  

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:

[tex]m = \frac{(8)-(2)}{(4)-(1)} \\m = \frac{8-2}{4-1} \\m = \frac{6}{3} \\m = 2[/tex]

So, the slope is 2.  

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].

Since [tex]m[/tex] represents the slope, substitute 2 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose one of the given points (it doesn't matter which one, the results will equal the same thing) and substitute its x and y values into the formula as well. (I chose (1,2), as seen below.) Then, isolate y to put the equation in slope-intercept form ([tex]y = mx + b[/tex] format) and find the following answer:

[tex]y-(2) = 2 (x-(1))\\y-2 = 2(x-1)\\y -2 = 2x-2\\y = 2x+0\\y = 2x[/tex]

Answer and Explanation:

If, on the other hand, the graph "flexes" or "flattens out" to some degree when it goes to cross the axis, then the zero is of a higher multiplicity; that is, it'll be of multiplicity three, five, or higher.

When a graph doesn't start at 0, it means that the graphs before it is not shown.

For number 4, I'd suggest Graph 3.

For number 3, I'd suggest graph 1.

For number 5, Write something along the lines of "Graph 2 does not show the car stopping slowly, it stops suddenly. Then it starts going really fast and stops suddenly again."
