Total students = 16

1. Total 9th graders = 3

Probability of being 9th grader = 3/16

2. Total that like comedy = 6

Probability = 6/16 = 3/8

3. 3 like action so 16-3 = 13 do not.

Probability = 13/16

4. 1 10th grader likes comedy out of 5 10th graders

Probability = 1/5

5. 0 out of 3 12th graders like comedy.

Probability = 0

6. 0 like action out of 3

Probability = 3/3 = 1

7. Yes the probabilities are different.

Answer:

1. P) 3/16

2. P)  6/16  or 3/8

3. P)  13/16   as  1- 3/16 = 13/16

4. P)  2/3

5. P) 1/5  

6. P) 3/3 = 1

7. Yes as such grades do not represent the no of people shown on the table

Which statement is TRUE concerning the slope of the line formed by the hypotenuse of each triangle? A) The slope formed by ΔABC
guajiro [1.7K]

Answer:

<em>A. The slope formed by ΔABC has a value that is 1/2 the slope formed by ΔCDE</em>

Step-by-step explanation:

Find the diagram attached.

Slope is the change in y coordinates tom that of x coordinate of a line.

Slope = Δy/Δx

Slope = y2-y1/x2-x1

For ΔABC,

A(-3, 6) and C = (-1, 3)

Slope = 3-6/-1-(-3)

Slope = -3/-1+3

Slope = -3/2

Slope of line AC is -3/2

For ΔCDE,

C = (-1, 3) and E = (3, -3)

Slope = -3-3/3-1

Slope = -6/2

Slope = -3

Slope of line CE is -3

From the calculation above, it can be seen that Slope of ΔABC = 1/2(slope of ΔCDE)

-3/2 = 1/2 (-3)

-3/2 = -3/2

<em>Hence the correct option is A. The slope formed by ΔABC has a value that is 1/2 the slope formed by ΔCDE</em>

Assume that when adults with smartphones are randomly​ selected,41 ​% use them in meetings or classes. If 5 adult smartphone use
kotegsom [21]

Answer:

0.345

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

n = 5, r = 2, p = 0.41, and q = 0.59.

P = ₅C₂ (0.41)² (0.59)⁵⁻²

P = 0.345
