What is the equation of the line that is

Mathematics
1 answer:
Fantom [35]3 years ago
3 0

Answer:

y = m_{AB}(X-2)-1

Step-by-step explanation:

When two lines are parallel means that their slopes are equal. Therefore the line AB will have same slope to a parallel second line, m_{AB} = m_{2}.

To obtain the slope from the line AB, we need two points, so the general equation will be:

m_{AB} = \frac{y_{B} -y_{A}  }{x_{B}-x_{A}  }

The typical equation of a line is written as y = mx + b

The second line will pass through point (2, -1), so we can substitute:

y2 = mX2 + b

-1 = -1=m_{AB} (2)+b(2) + b

then the interception is b=-m_{AB} -1

Now to obtain a general equation for the second parallel line will be:

y =  m_{AB} X + b

y =  m_{AB} X - m_{AB}(2)-1

Finally we get:

y =  m_{AB} (x-2)-1

What is the mean in 74,75,80,76,75,81,78?
Alina [70]

Answer:

77

Step-by-step explanation:

Add the numbers together, then divide them to how much numbers are there.

74 + 75 + 80 + 76 + 75 + 81 + 78 = 539

Since there are 7 numbers, you divide 539 by 7.

539/7 = 77

Ksenya-84 [330]

Both the sample can be used to make inferences about the population.

The correct option is D.

Given

Jason and Yolanda both drew a simple random sample from a non-normally distributed population of 25,000.

Jason’s sample consisted of 0.24% of the population, while Yolanda’s sample consisted of 0.32% of the population.

<h3>Percentage;</h3>

A percentage is a number or ratio that can be expressed as a fraction of 100.

According to the question

Total number of population = 25000

Percent of a sample of Jason = 0.24%

Percent of the sample of Yolanda's = 0.32%

So, the number of the population according to Jason's sample is given by;

=\dfrac{0.24}{100}\times 25000\\\\=0.24 \times 250\\\\=60

The number of the population according to Yolanda's sample is given by;

=\dfrac{0.32}{100}\times 25000\\\\=0.32 \times 250\\\\=80

Hence, Both the sample can be used to make inferences about the population

Andy has a collection of movie dvds. in andys collection 3/5 of the dvds are action 1/4 of the dvds are comedy. andy said that 4
Lerok [7]
If 3/5 are action and 1/4 are comedy then:

(3/5)+(1/4) are action or comedy

To add/subtract fractions you need a common denominator...

(3/5)*(4/4)+(1/4)(5/5)

(12/20)+(5/20)

17/20

So 17/20 (85%) of his collection are action or comedy not 4/9...
