Ashley has a box of donuts to distribute among her colleagues. There are eight chocolate donuts, twelve glazed donuts, ten jelly

donuts, two cinnamon donuts, and four rainbow sprinkled donuts in the box. Ashley predicts that when she draws a donut out of the box without looking, she will draw a glazed donut one-third of the time.
Which activity would best allow Ashley to test her prediction?

A.
Randomly select a donut from the box and see if it is a glazed donut.
B.
Randomly select a donut. Then, continue to draw another donut until twelve glazed donuts are drawn.
C.
Randomly select and replace a donut 72 times. Then, observe how close to 18 times a glazed donut is drawn.
D.
Randomly select and replace a donut 72 times. Then, observe how close to 24 times a glazed donut is drawn.

What is the midpoint to the segment below?
shtirl [24]

Step-by-step Answer:

The coordinates of the mid-point of a segment whose end-points are known is the average of the coordinates of the end-points.

Here, the end-points are: (-11,0), (9,-1)

So the x-coordinate of the mid-point is (-11+9)/2 = (-2/2) = -1, and

the y-coordinate of the mid-point is (0-1)/2 = -0.5

So the mid-point is (-1,-0.5)

Check the numbers by plotting the point on the graph!

How would you solve for x here
Alex Ar [27]

Answer:

x=-1.30068.......

Step-by-step explanation:

x( 3x^2 - 2) = -4

Distribute

3x^3 - 2x = -4

Add 4 to each side

3x^3 - 2x +4 = 0

Plot using a graphing calculator

x=-1.30068.......

Given:

Line a passes through (2, 10) and (4, 13).

Line b passes through (4, 9) and (6, 12).

Line c passes through (2, 10) and (4, 9).

To find:

Which of the lines, if any are perpendicular.

Solution:

If a line passes through two points, then the slope of line is

m=\dfrac{y_2-y_1}{x_2-x_1}

Line a passes through (2, 10) and (4, 13).  So, slope of this line is

m_a=\dfrac{13-10}{4-2}=\dfrac{3}{2}

Line b passes through (4, 9) and (6, 12).  So, slope of this line is

m_b=\dfrac{12-9}{6-4}=\dfrac{3}{2}

Line c passes through (2, 10) and (4,9).  So, slope of this line is

m_c=\dfrac{9-10}{4-2}=\dfrac{-1}{2}

Product of slopes of to perpendicular lines is -1.

m_a\cdot m_b=\dfrac{3}{2}\times \dfrac{3}{2}=\dfrac{9}{4}\neq -1

m_b\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1

m_a\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1

Therefore, any of these lines are not perpendicular to each other.

Hi, can you please solve that fast?​
Elenna [48]

Answer:

A.

Step-by-step explanation:

4 < 6t + 1 ≤ 43 (Given)

3 < 6t ≤ 42 (Subtracted 1 on both sides)

1/2 < t ≤ 7 (Divided 6 on both sides)

You are looking for an open dot on 1/2 and a shaded dot on 7 with a line between them. Therefore, the answer is A.
