You roll a 6-sided die.
What is P(5)?
Write your answer as a fraction or whole number.

Answers

Answer:

1/6

Step-by-step explanation:

there is one 5 on the die. therefore the chance of rolling a 5 is 1/6

The required probability P(5) = 1/6.

What is probability?

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

The die has only one 5 on it.

The number of favorable outcomes = 1

There are the total outcomes as {1, 2, 3, 4, 5, 6}

So the total number of outcomes = 6

Required probability P(5) = 1/6

Hence, the chance of rolling a 5 is 1/6

Four friends shared 3 orders of chicken wings. • Alex ate 5 of an order. ·8· • Chase ate 7 of an order. ·8· • Ella ate 6 of an order. ·8· How much chicken is left for the fourth friend?

Answers

Answer: 3/4

Step-by-step explanation:

Amount of chicken ordered = 3

Fraction eaten by Alex = 5/8

Fraction eaten by Chase = 7/8

Fraction eaten by Ella = 6/8

The chicken ate by the three friends will be:

= 5/8 + 7/8 + 6/8

= 18/8

= 2 2/8

= 2 1/4

Now, the chicken left for the forty friend will be:

= 3 - 2 1/4

= 3/4

What are trigonometric ratios?

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given that, MK=8 units, ∠M=40° and ∠K=50°.

We know that, sinθ=Perpendicular/Hypotenuse

Now, sin40°=KL/8

0.6427=KL/8

KL=0.6427×8

KL=5.1 units

sin50°=ML/8

0.7660=ML/8

ML=6.1 units

Therefore, the measure of KL is 5.1 unit and the measure of ML is 6.1 unit.

A game of "Doubles-Doubles" is played with two dice. If a player rolls doubles, the player earns 3 points and gets another roll. If the player rolls doubles again, the player earns 9 more points. How many points should the player lose for not rolling doubles in order to make this a fair game?

Answers

Answer:

27/35 points

Step-by-step explanation:

The probability of getting one double;

P(getting one double) = 5/36

Probability of getting two doubles is;

P(getting two doubles) = 1/36

Probability of getting no doubles is;

P(getting no doubles) = 1/36

For us to find the Number of points that the player should lose for not rolling doubles, we have;

(12/36) + (5(3 - x)/36) - (5x/6) = 0

(12/36) + (15 - 5x)/36 - 5x/6 = 0

Multiply through by 36 to get;

12 + 15 - 5x - 30x = 0

35x = 27

x = 27/35

A line with what type of slope contains the points (-2, 5) and (-2, 6)?

Answers

Answer:

undefined

Step-by-step explanation:

To find the slope

m = ( y2-y1)/(x2-x1)

   = ( 6-5)/( -2 - -2)

   = (6-5) /(-2+2)

    = 1/0

We cannot divide by zero, so the slope is undefined
