There are 10 sweets in a box. There are n jelly beans and the rest are cola bottles. Colin takes 2 sweets out of the box at random. Write an expression for the probability of getting 2 jelly beans. Give your expression as a single fraction and simplify fully.

Answers

Answer 1

The probability expression is n/10 * (n - 1)/9 and the single fraction is n(n - 1)/90

How to determine the probability expression?

We understand that there are 10 sweets in the box

Such that

Jelly beans = n

This means that

The rest = 10 - Jelly beans

So, we have

The rest = 10 - n

The probability of 2 jelly bean sweet is represented as

P(2 jelly bean sweets) = P(First jelly bean sweets) * P(Second jelly bean sweets)

This gives

P(2 jelly bean sweets) = n/10 * (n - 1)/9

Solving further, we have

P(2 jelly bean sweets) = n(n - 1)/90

Hence, the probability is n(n - 1)/90

An experiment consists of spinning the spinner once.​ ​ a). What is the probability of landing on a 2. ​ ​ b). What is the probability of landing on a 1?​ ​ c). Is landing in each section of the spinner equally likely to occur? Explain.​

Answers

Answer:

1/4 ; 3/8

Step-by-step explanation:

Probability of landing on 2 :

Required outcome = Number of 2's on spinner = 2

Total possible outcomes = Number of congruent spaces on spinner = 8

P(landing on a 2) = 2 / 8 = 1/4

Probability of landing on 1 :

Required outcome = Number of 1's on spinner = 3

Total possible outcomes = Number of congruent spaces on spinner = 8

P(landing on a 1) = 3 / 8

Landing in each section of the spinner is equally likely to occur as the spinner are divided into congruent spaces. However, landing on the labels of the spinner isn't equally likely as each label take up uneven number of congruent spaces on the spinner.

Graph h(x) = -|x- 6| + 3.

Answers

Answer: Shift the graph to the right by 6, and up by 3.

Step-by-step explanation: If a number is in parentheses or absolute value lines, use the inverse sign. If it’s outside of the parentheses, move it like normal.

To graph the function h(x) = -|x - 6| + 3, we can follow a step-by-step approach:

Step 1: Determine the key points:

Identify the vertex: The vertex of the absolute value function y = |x| is at (0, 0). In this case, since we have y = -|x - 6| + 3, the vertex is obtained by shifting the vertex (0, 0) horizontally by 6 units to the right and vertically up by 3 units. Therefore, the vertex is at (6, 3).

Find additional points: Choose some x-values on both sides of the vertex to determine corresponding y-values. Let's choose x = 0, 3, 6, and 9.

Step 2: Calculate the y-values:

For x = 0: h(0) = -|0 - 6| + 3 = -|-6| + 3 = -6 + 3 = -3.

For x = 3: h(3) = -|3 - 6| + 3 = -|-3| + 3 = -3 + 3 = 0.

For x = 6: h(6) = -|6 - 6| + 3 = -|0| + 3 = -0 + 3 = 3.

For x = 9: h(9) = -|9 - 6| + 3 = -|3| + 3 = -3 + 3 = 0.

Step 3: Plot the points:

Plot the points (0, -3), (3, 0), (6, 3), and (9, 0) on a coordinate plane.

Step 4: Draw the graph:

Connect the plotted points smoothly. Since we have an absolute value function with a negative sign, the graph will be an upside-down V-shape, opening downwards, with the vertex at (6, 3).

Here's a visual representation of the graph of h(x) = -|x - 6| + 3:

Yesenia has a 13 ft ladder that she placed against a
wall. How far up the wall will the ladder reach when the
base of the ladder is 5 ft from the wall?

Answers

Answer:

12 ft

Step-by-step explanation:

Using formula (pythagorean theorem)

a² + b² = c²

Where :

13 = c

and 5 = a

5² + b² = 13²

25 + b² = 169

169 - 25 = b²

144 = b²

Sq root b = 12

It will reach up 12 ft.

Now, subtract -3 from -10.

Subtracting a negative number is the same as adding a positive number, so add 3 to -10.

-10 + 3

= -7

Put together 8a and -7
