alisha [4.7K]

Step-by-step explanation:

<u>YELLOW TRIANGLE:</u>

<u>\sin(30)  =  \frac{x}{12}  \\ x = 12 \sin(30)  = 6</u>

<u>PURPLE TRIANGLE:</u>

Since one of the angle is 45°, x = BC = 6

To prove:

\tan(45)  =  \frac{bc}{x}  \\ bc = x \tan(45)  = 6 \tan(45)  = 6

<u>PINK TRIANGLE:</u>

<u>\tan(60)  =  \frac{bc}{y}  \\ y =  \frac{bc}{ \tan(60) }  \\  =  \frac{6}{ \tan(60) }  \\  = 2 \sqrt{3}</u>

kirill115 [55]

Answer:

(-5/6)x - 1

Step-by-step explanation:

the equation is given by: y = mx + b

m = slope

b = y intercept

m = -5/6

y intercept = -1

f(x) = (-5/6)x - 1

Timothy creates a game in which the player rolls 4 dice. What is the probability in this game of having exactly two dice or more
devlian [24]

Answer:

B. 0.132

Step-by-step explanation:

For each time the dice is thrown, there are only two possible outcomes. Either it lands on a five, or it does not. The probability of a throw landing on a five is independent of other throws. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Timothy creates a game in which the player rolls 4 dice.

This means that n = 4

The dice can land in 6 numbers, one of which is 5.

This means that p = \frac{1}{6}

What is the probability in this game of having exactly two dice or more land on a five?

P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4)

In which

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{4,2}.(\frac{1}{6})^{2}.(\frac{5}{6})^{2} = 0.116

P(X = 3) = C_{4,2}.(\frac{1}{6})^{3}.(\frac{5}{6})^{1} = 0.015

P(X = 4) = C_{4,4}.(\frac{1}{6})^{4}.(\frac{5}{6})^{0} = 0.001

P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.116 + 0.015 + 0.001 = 0.132

So the correct answer is:

B. 0.132

The perimeter of a rectangular garden is 110ft. The length is 5 ft greater than the width. Find the length and width.
tigry1 [53]

P = perimeter

L = length

W = width

Formula for the perimeter of a rectangle = L + L + W + W  or  P = 2L + 2W

You know:

P = 110ft

L = W + 5  [length is 5ft greater than the width]

So plug this into the formula:

P = 2L + 2W             Substitute/plug in (W + 5) for L

110 = 2(W + 5) + 2W           Distribute/multiply 2 into (W + 5)

110 = (2)W + (2)5 + 2W

110 = 2W + 10 + 2W       Combine like terms (2W + 2W)

110 = 4W + 10       Subtract 10 on both sides

110 - 10 = 4W + 10 - 10

100 = 4W     Divide 4 on both sides to get "W" by itself

\frac{100}{4}=\frac{4W}{4}

25 = W        Now that you know the width, plug it into the equation for length

L = W + 5       Plug in 25 for W

L = 25 + 5

L = 30

L = 30 ft

W = 25 ft

PROOF

P = 2L + 2W

110 = 2(30) + 2(25)

110 = 60 + 50

110 = 110
