Need help with a math question

Mathematics
1 answer:
CaHeK987 [17]3 years ago
6 0

<u>Answer:</u>

57%

<u>Step-by-step explanation:</u>

We are given the results of survey of one thousand families to determine the distribution of families by their size.

We are to find the probability (to the near percent) that a given family has 3, 4 or 5 people.

Frequency of families with 3, 4 or 5 people = 200 + 245 + 125 = 570

Total frequency = 1000

P (families with 3, 4 or 5 people) = (570 / 1000) × 100 = 57%

In what ways can horizontal, vertical, and oblique asymptotes be identified?
antiseptic1488 [7]
A horizontal asymptote y = a is a horizontal line which a curve approaches as x approaches positive or negative infinity. If the limit of a curve as x approaches either positive or negative infinity is a, then y=a is a horizontal asymptote.

A vertical asymptote x = b is a vertical line that a curve approaches but never crosses. The value b is not in the domain of the curve. More precisely if the limit of a curve as x approaches b is either positive or negative infinity then x=b is a vertical asymptote.

An oblique asymptote is a diagonal line (a line whose slope is either positive or negative) that a curve approaches. For a rational function R(x) = P(x) / Q (x) an oblique asymptote y = my + b is obtained by dividing P(x) by Q (x). Doing so will yield a quotient and remainder. If we set the quotient equal to y that gives the equation of the oblique asymptote.

Anestetic [448]

A word problem is used to solve problems in mathematics without the explicit use of equations initially.

<h3>What is a Word Problem?</h3>

This refers to the use of words to generate an equation that can be solved by mathematical means.

Hence, we can see that because the question is incomplete, we can infer that there is a relationship that exists between Dr. White, Dr. Black, Dr. Brown, and a woman that does not have brown hair, and equality would be used to solve it.

Write the equation of the line that passes through the point (6,-2) and is parallel to the line y=1/3x+8
Dahasolnce [82]

If a line is parallel to another it has the same slope. Since the equation y = 1/3x +8 is parallel to the line we are trying to find, our second line will have the slope of 1/3x as well

This is the equation of a line:

y = mx + b

m = slope = 1/3x

b = y intercept = unknown

We have to find b to make this equation complete. How do we do this?

First plug what you know into the equation: y = 1/3x + b

Second we must solve for b. To do this plug a point that passes through the line (in this case they said (6, -2) passes through the line) into the x and y of the equation:

-2 = 1/3(6) + b

Now solve for b!

-2 = 6/3 + b

-2 = 2 + b

- 2 - 2 = b

-4 = b

The equation parallel to y=1/3x + 8 and passes through point (6, -2) is y = 1/3x - 4

The image below is the two line one a coordinate plane. As you can see, they are parallel to each other

Hope this helped!
