Of the 14 clients at Bob's salon, 7 of them have red hair. What is the probability that a randomly selected client at Bob's salon has red hair? P(red) =

Answers

Answer 1
|S|=14|E|=7

Now

[tex]\\ \rm\Rrightarrow P(E)=\dfrac{|E|}{|S|}[/tex]

[tex]\\ \rm\Rrightarrow P(E)=\dfrac{7}{14}=1/2[/tex]

Answer 2

Answer:

[tex]\mathsf{Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ outcomes}}[/tex]

Given:

Total number of outcomes = total number of clients = 14Number of ways it can occur = number of clients with red hair = 7

[tex]\implies \mathsf{Probability \ of \ red\ hair= \dfrac{7}{14}=\dfrac12=0.5}[/tex]

• A baker uses 3 tablespoon of melted butter for every kilogram of flour.
How many tablespoons of melted butter he used for 13 kilograms of
flour?

חח ך

Answers

Answer:

48.6 tablespoons

Step-by-step explanation:

If for every kg of flour 3.6 (3 3/5) tablespoons are used, then for 13.5 (13 1/2) kgs: 3.6 × 13.5 = 48.6 tablespoons are used.

From the question,

[tex]3\frac{3}{5}[/tex] tablespoons of melted butter = 1 kilogram of flour

The number of tablespoons of melted butter the baker can use for 13 kilograms of flour is calculated as

1 kilogram of flour =  [tex]3\frac{3}{5}[/tex] tablespoons of melted butter

[tex]13\frac{1}{2}[/tex] kilograms of flour = b

Cross multiply

1 kilogram of flour x b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter

b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter  /1 kilogram of flour

b = 48.6 tablespoons of melted butter

Therefore, the baker would use 48.6 tablespoons of melted butter for [tex]13\frac{1}{2}[/tex]kilograms of flour.

Use the diagram shown. Solve for x. Find the angle measures to check your work. (Edit: nevermind i got the answer)

Answers

Answer:

x = 9

m<AOB = 29°

m<BOC = 57°

m<COD = 29°

Step-by-step explanation:

Given:

m<AOB = (4x - 7)°

m<BOC = (5x + 12)°

m<COD = (2x + 11)°

The diagram shows <AOB is congruent to <COD.

Set both angles equal to each other to find x.

m<AOB = m<COD

4x - 7 = 2x + 11

Collect like terms

4x - 2x = 7 + 11

2x = 18

Divide both sides by 2

2x/2 = 18/2

x = 9

Find the measure of each angle by plugging in the value of x into each expression for each angle:

m<AOB = (4x - 7)° = 4(9) - 7 = 36 - 7 = 29°

m<BOC = (5x + 12)° = 5(9) + 12 = 45 + 12 = 57°

m<COD = (2x + 11)° = 2(9) + 11 = 18 + 11 = 29°

Answers

Answer:

Choice A describes a function

Step-by-step explanation:

Relations and Functions

A relation is a set of inputs and outputs with no restrictions. A function is a relation with one output for each input.

This means that if at least one input has more than one output, it's not a function.

Analyzing each choice:

A: It can be noted that each input (2,-2,0,-3) has only one output. Thus this set describes a function.

B: Input 1 has two outputs (5,6), thus this is not a function.

C: Input 6 has two outputs (-4,-1), thus this is not a function.

D: Input 2 has two outputs (7,2), thus this is not a function.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
