Okay so the equation given to you, tells you that the slope must be 4. The line must pass through the point (4,8). so, you have to put it into point-slope form in order to find your answer. the equation for point slope form is y-y1 =m(x-x1). in the equation, y1 and x1 are given in the point (4,8), so you point slope equation will be y-8=4(x-4). then you solve the equation. hope this helps! :)

Slope intercept form is:

y = mx + b

"m" is the slope, "b" is the y-intercept (when x = 0)


I'm assuming that the equation of a line is parallel to the given line.

When lines are parallel, they have the same slope.

The given line's slope is 4, so the parallel line's slope is also 4


y = mx + b

y = 4x + b


To find b, you plug in the point (4,8) into the equation.

y = 4x + b

8 = 4(4) + b

8 = 16 + b  Subtract 16 on both sides

-8 = b


Your equation is:

y = 4x - 8

The probabilities are:

  • P(red) = 5/24
  • P(orange) =  0
  • P(blue) =  1/3
  • P(not green)= 17/24
  • P(green or black) = 11/24
  • P(not yellow)  = 1.

<h3>How to find the probabilities?</h3>

The probability of getting a particular color of marble, is given by the quotient between the number of marbles of that color and the total number of marbles.

Here we have:

  • 5 red marbles.
  • 7 green marbles.
  • 4 black marbles.
  • 8 blue marbles.

So the total number is 5 + 7 + 4 + 8 = 24.

Then:

  • P(red) = 5/24
  • P(orange) = 0/24 = 0  (because there are 0 orange marbles).
  • P(blue) = 8/24 = 1/3
  • P(not green) = (24 - 7)/24 = 17/24
  • P(green or black) = (4 + 7)/24 = 11/24
  • P(not yellow) = 24/24 = 1 (because there aren't yellow marbles).

Answer the questions about the dot and box plot.
ivanzaharov [21]

Answer:

a. 104

b. 102, 104, and 105

Step-by-step explanation:

a. There are 13 data points plotted on the dot line. The median lies between the 6th and 7th data point.

Thus, on the dot line, the 6th and 7th data points both fall on 104.

Therefore, median = 104

b. The dot plot shows the high temperatures that occurred more than one day are:

102, 104, and 105

Each face of a cube has an area of 16 inches squared what is the volume of the cube
lakkis [162]

Answer:

64 in³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( where s is the length of the side )

Given

area = 16, then

s² = 16 ( take the square root of both sides )

s = \sqrt{16} = 4 , thus

V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³
