Determine the probability of rolling a number that is not even.


a. Which outcome or outcomes make up the event of rolling a number that is not even?


b. Calculate the probability of rolling a number that is not even.

Answers

Answer 1

Answer:

[tex]\frac{1}{2}[/tex] or 0.5 or 50%

Step-by-step explanation:

P(not even) = P(odd) = P(1) or P(3) or P(5) = P(1) + P(3) + P(5)

= [tex]\frac{1}{6}[/tex]+ [tex]\frac{1}{6}[/tex]+[tex]\frac{1}{6}[/tex] = [tex]\frac{3}{6}[/tex]= [tex]\frac{1}{2}[/tex]

Alternatively

P(not even) = 1 -P(even) = 1 - [P(2) or P(4) or P(6)]

= 1 - [ [tex]\frac{1}{6}[/tex]+ [tex]\frac{1}{6}[/tex]+[tex]\frac{1}{6}[/tex]] = 1 - [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

find x using
dialations

Answers

Answer:

x = 14.4

Step-by-step explanation:

Using dilations, the following equation can be written to show the relationship between the two similar triangles:

x/4 = (6.5 + 2.5)/2.5

x/4 = 9/2.5

Cross multiply

x*2.5 = 9*4

2.5x = 36

2.5x/2.5 = 36/2.5

x = 14.4

Write the equation based on the picture and calculate the mass of the unknown package.

Answers

Answer:

Step-by-step explanation:

5x + 2 = 4 x + 7

x = 5

Answer:

5x + 4 = 4x + 7

x = 3

Step-by-step explanation:

Let's call the mass of the unknown package "x". The equation is:

2+2 + x+x+x+x+x = x+x+x+x + 2+5

5x + 4 = 4x + 7

Now let's solve for x

5x + 4 = 4x + 7

x + 4 = 7

x = 3

A clothing manufacturer offers 2 different styles of jeans, relaxed fit and regular fit, in 5 different colours. How many combinations of a style and a colour are possible?

Answers

Answer:

10 combinations

Step-by-step explanation:

We can solve the above question using the Fundamental Counting Principle.

This states that:

If an event has x possible outcomes and a other event has y possible outcomes, then there are x and y total possible outcomes for the two events together.

We are told in the above question that:

Styles of jeans = 2

Number of colors = 5

Hence,the number of combinations of a style and a colour that are possible is calculated as:

5 × 2 = 10 combinations

Write a quadratic function in standard form whose graph satisfies the given conditions.
passes through
0, 0 , 2, 4 , and 4, 0

Answers

Answer:

y = -x² + 4x

Step-by-step explanation:

The standard form:

y = ax² + bx + c

Pairs given:

(0, 0), (2, 4), (4, 0)

Substitute values of x and y and work out the values of a, b and c.

1. Point (0, 0)

0 = a(0)² + b(0) + c  ⇒ c = 0

2. Point (2, 4)

4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a

3. Point (4, 0)

0 = a(4)² + b(4) ⇒ 16a + 4b = 0

Substitute b and solve for a:

16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1

Find b:

b = 2 - 2(-1) = 2 + 2 = 4

The function is:

y = -x² + 4x
