Answer:

  • Translation (x, y) → (x + 5, y + 7)

Step-by-step explanation:

<u>It seems the translation:</u>

  • (x, y) → (x + 5, y + 7)

R(-4, -1) → R'(-4 +5 = 1, -1 +7 = 6)

S(-6, 3) → S'(-6 + 5 = -1, 3+7 = 10)

Can an equation be true or false? Explain.
Aleks04 [339]

The answer to whether an equation can be true or false is; Yes

<h3>Equations</h3>

Yes an equation can be true or false. This is because for example if we have the equation;

3x + 5 < 12

For this equation to hold true, only certain values of x can be possible which we will call as possible solutions. Whereas any values outside of the possible range of x will make the equation to be false.

Find an equation for the line with the given properties. Express your answer using either the general form or the slope -interce
Nastasia [14]

Answer:

y=3x-4

Step-by-step explanation:

We have been given that the slope of line is 3 and point (2,2) is on the line. We are asked to write the equation of the line passing through the given point in slope-intercept form.

The slope-intercept form of equation is in form y=mx+b, where,

m = slope of line.

b = The y-intercept.

Upon substituting our given slope and coordinates of given point in slope-intercept form, we will get:

2=3(2)+b

2=6+b

2-6=6-6+b

-4=b

Now, we will substitute m=3 and b=-4 in slope-intercept form as:

y=3x+(-4)

y=3x-4

Therefore, our required equation would be y=3x-4.

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
