y= 3x - 5 y=-3x + 7 y - 3x = -12 y + 1/3x=8​

Answers

Answer:

line 1 and 3

Step-by-step explanation:

hello!

Parallel lines have the same slope.

So if we're asked to identify a pair of parallel lines, we can just take a look at the slope (the number before x)

The first one is y=3x-5. Okay.

The second one is y=-3x+7. So the second line isn't parallel to the first line.

The third line is y-3x=12, or y=3x+12.

So the 3rd line is parallel to the 1st line :)

A counselor determined that 60% of the senior class had taken a precalculus course and that 15% of the senior class had taken both a precalculus course and a statistics course?
What percentage of seniors who took a precalculus course also took a statistics course?

Answers

Using conditional probability, it is found that 25% of seniors who took a precalculus course also took a statistics course.

What is Conditional Probability?

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which:

P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.

In this problem, the events are:

Event A: Senior student took a precalculus course.Event B: Senior student took a statistics course.

The probabilities given are [tex]P(A) = 0.6, P(A \cap B) = 0.15[/tex].

The desired probability is P(B|A), hence:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.15}{0.6} = 0.25[/tex]

0.25 = 25% of seniors who took a precalculus course also took a statistics course.

Is (10, 8) a solution to this system of equations?
2x - 5y = -20
X + 9y = 14
A
O a. Yes
b. No

Answers

Answer: No, there isn't anything showing that it is.

No

Step-by-step explanation:

Substitute value of x (10) & y (8) in both equation

x + 9y =14

10 + 9 x 8 = 82

(doesn't give us the output of 14)

2x - 5y = -20

2 x 10 - 5 x 8 = - 20

(this does, but both have to work)

Solution is at (-4.8,2.1):

2x +18y =28

2x - 5y = -20

(minus)

(18 - - 5 & 28 - - 20 those minus becomes a + )

23y = 48

÷23

y= 48/23

(2.1 to 1d.p)

Substitute y to find x

2x - 5y = -20

2x - 5 x 48/23 = - 20

2x - 240/23 = - 20

+240/23

2x = -220/23

÷2

x = - 110/23

X= -4.8 to 1d.p

(-110/23, 48/23)

Answers

The question refers to the speed of sound waves. The expression that shows the waves from the fastest to the slowest is option A. See attached for full question

What are sound waves?

A sound wave is the rhythm of disruption induced by the flow of energy as it propagates away from the source of the sound across a medium.

Why is option A the correct answer?

Option A - is the correct answer because the temperature of a medium ( which may be air, water, or solid matter) affects the speed at which waves of sound travel through it.

The faster sound waves flow through a medium, the higher its temperature. This is why Wave X will pass through the fastest at 33°C, followed by Wave W at 15°C, etc.

The lengths of a particular snake are approximately normally distributed with a given mean mu = 15 in. and standard deviation sigma = 0.8 in. what percentage of the snakes are longer than 16.6 in.?

Answers

The percentage of the snakes is longer than 16.6 in. with a mean of 15 in. and a standard deviation of 0.8 in. is 2.275%.

What is a normal distribution?

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The lengths of a particular snake are approximately normally distributed with a given mean = 15 in. and standard deviation = 0.8 in.

Then the percentage of the snakes is longer than 16.6 in. will be

[tex]z = \dfrac{ x - \mu }{ \sigma }\\\\z = \dfrac{16.6-15}{0.8}\\\\z = 2[/tex]

Then we have

[tex]\rm P(x > 16.6) = P(z > 2) = 0.02275 \ or \ 2.275 \%[/tex]

The elongation α
of a planet is the angle formed by the planet, earth, and sun. it is known that the distance from the sun to venus is 0.723au
(see exercise 65 in section 6.2 ). at a certain time the elongation of venus is found to be 39.4∘.
find the possible distances from the earth to venus at that time in astronomical units (au).

Answers

The distance from the earth to venus is an illustration of the sine ratio

The distance from the earth to venus at that time is 1.12 au

How to determine the possibe distance?

See attachment for the diagram that illustrates the complete question.

Start by calculating the angle V using the following sine ratio

SE/sin(V) = VS/sin(E)

This gives

1/sin(V) = 0.723/sin(39.4)

Take the inverse of both sides

sin(V)/1 = sin(39.4)/0.723

Evaluate the quotient

sin(V) = 0.8779

Take the arcsin of both sides

V = 61.4

Calculate the measure of angle S

<S + <V + <E = 180

This gives

<S  = - <V - <E + 180

Substitute known values

<S  = -61.4 - 39.4 + 180

<S  = 79.2

The distance (VE) is then calculated using the following sine ratio

VE/sin(S) = VS/sin(E)

This gives

VE/sin(79.2) = 0.723/sin(39.4)

Multiply bot sides by sin(79.2)

VE = sin(79.2) * 0.723/sin(39.4)

Evaluate the product

VE = 1.12

Hence, the distance from the earth to venus at that time is 1.12 au
