First of all: subtract 3 from 3x then from 2y then divide

Given the point (-1, 8), answer the questions below: After that point was translated 5 units right and 4 units up, the coordinat

Rom4ik [11]

a) x=4 is 5 units to the right of x=-1.

y=12 is 4 units up from y=8.

Your point (-1, 8) is translated to (4, 12).

___

b) If the parent function f(x) = x is translated so it goes through (4, 12), the translated function can be written ...

... g(x) = f(x-4) +12 = (x -4) +12

... g(x) = x +8

Answer:

$P(X > 0) = 0.9222$

Step-by-step explanation:

For each name, there are only two outcomes. Either the name is authentic, or it is not. So, we can solve this problem using the binomial probability distribution.

Binomial probability distribution

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

$P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}$

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

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

And $\pi$ is the probability of X happening.

In this problem.

5 names are selected, so $n = 5$

A success is a name being non-authentic. 40% of the names are non-authentic, so $\pi = 0.40$ .

We have to find $P(X > 0)$

Either the number of non-authentic names is 0, or is greater than 0. The sum of these probabilities is decimal 1. So:

$P(X = 0) + P(X > 0) = 1$

$P(X > 0) = 1 - P(X = 0)$

$P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}$

$P(X = 0) = C_{5,0}*(0.40)^{0}*(0.6)^{5} = 0.0778$

$P(X > 0) = 1 - P(X = 0) = 1-0.0778 = 0.9222$

Question 28: Please help, which pairs of angles could she have used?

TiliK225 [7]

The answer is A because opposite angles are the same. Therefore, 1 and 2 are congruent because their angle sizes are exactly the same.
