Triangles A B C and X Y Z are shown. Which would prove that ΔABC ~ ΔXYZ? Select two options. StartFraction B A Over Y X = StartF

sergejj [24]

Answer: Answer is 3

BC 6

------ = ------

XY 3

Step-by-step explanation:

The statements below can be used to prove that the triangles are similar.

On a coordinate plane, right triangles A B C and X Y Z are shown. Y Z is 3 units long and B C is 6 units long.

A B Over X Y = 4 Over 2

A C Over X Z = 52 Over 13

△ABC ~ △XYZ by the SSS similarity theorem.

Which mathematical statement is missing?

1. Y Z Over B C = 6 Over 3

2. ∠B ≅ ∠Y

3. B C Over Y Z = 6 Over 3

4. ∠B ≅ ∠Z

Answer:

x=-3/7 and y=_23/7

Step-by-step explanation:

y=-4x-5 and y=3x-2

using comparison method

-4x-5=3x-2

-4x-3x=-2+5

-7x=3

x=3/-7

substituting the value of x

y=3x-2

=3×(-3/7)-2

=-9/7-2

=-9-14/7

=-23/7

Answer:

<h3>☘ QUESTION☘</h3>

What is the slope of the line?

-3x+5y=2x+3y

<h3>☘ ANSWER☘</h3>

-3x+5y=2x+3y → 2y = 5x → y = (5/2)x.

There are infinitely many ordered pairs that satisfy -3x+5y=2x+3y.

According to national data, 5.1% of burglaries are cleared with arrests. A new detective is assigned to six different burglaries

blagie [28]

Answer:

26.95% probability that at least one of them is cleared with an arrest

Step-by-step explanation:

For each burglary, there are only two possible outcomes. Either it is cleared, or it is not. The probability of a burglary being cleared is independent of other burglaries. 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.

5.1% of burglaries are cleared with arrests.

This means that $p = 0.051$

A new detective is assigned to six different burglaries.

This means that $n = 6$

What is the probability that at least one of them is cleared with an arrest?

Either none are cleared, or at least one is. The sum of the probabilities of these events is 100% = 1. So

$P(X = 0) + P(X \geq 1) = 1$

We want $P(X \geq 1)$

Then

$P(X \geq 1) = 1 - P(X = 0)$

In which

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

$P(X = 0) = C_{6,0}.(0.051)^{0}.(0.949)^{6} = 0.7305$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.7305 = 0.2695$

26.95% probability that at least one of them is cleared with an arrest
