Write the equation of the line passing through the points (6,16) and (9,25).
First find the slope!

Answers

Answer:

y = 3x - 2

Step-by-step explanation:

Find the slope using rise over run (y2 - y1) / (x2 - x1), where (x1, y1 ) and (x2, y2) are points on the line.

Plug in the 2 points:

(y2 - y1) / (x2 - x1)

(25 - 16) / (9 - 6)

9 / 3

= 3

So, the slope is 3. Plug this and a point into y = mx + b to find b:

y = mx + b

16 = 3(6) + b

16 = 18 + b

-2 = b

Then, plug in b and the slope into the equation:

y = mx + b

y = 3x - 2 is the equation of the line

What is the least common denominator of 3/5 and 2/15?

Answers

Answer:

15

Step-by-step explanation:

3/5 = 9/15

2/15 = 2/15

The least common denominator of 3/5 and 2/15 is 15

The least common denominator is the least product value of the given fractions

To do that, we will find the greatest value between the denominators of each fraction

Given the fractions 3/5 and 2/15, we can see that the two integers at the nominator are 5 and 15.

Since 5 can go in 15 without remainder, we do not need to multiply both integers again. The least common denominator will be the greatest value between 5 and 15 and that is 15.

Hence the least common denominator of 3/5 and 2/15 is 15

Answer:

  equations: q+n = 103; 0.05n +0.25q = 8.75

  solution: q=18; n=85

Step-by-step explanation:

Write one equation for the number of coins:

  q+n=103.

Write another equation for the value of the coins:

  0.05n +0.25q = 8.75.

It is often convenient to substitute for the lower value, here, using n = 103-q. This results in an equation for q with positive coefficients.

  0.05(103 -q) +0.25q = 8.75

  5.15 +0.20q = 8.75

  0.20q = 3.60

  q = 18

  n = 103 -18

  n = 85

Sample A has a mean of M = 6. Sample B has a mean of M = 10. When the two samples are combined, the mean of the combined group is M = 9. Which of the following is the most accurate description for the two sample sizes?


The samples are the same size.

Sample A is much bigger than Sample B.

There is not enough information provided to determine this.

Sample B is much bigger than Sample A.

Answers

Answer:

Sample B is much bigger than Sample A

Step-by-step explanation:

It is because when seeing sample B alone we can see it has a larger mean than of Sample A. Mean is greater when the values we are using are of bigger value. Since Sample B has bigger values in it so it also a has bigger mean compared to Sample A which has a smaller mean (smaller values in it)

Which equation represents the line that passes through points (1, –5) and (3, –17)?​

Answers

Answer:

y=-6x+1

Step-by-step explanation:

If you have a line that passes through the points (1, -5) and (3, -17), the equation of this line will be y=-6x+1. For verification, -6+1=-5, so the first point is true, and -18+1=-17, so the second point is true as well.

Answers

Answer:

54.6 cm

Step-by-step explanation:

Hi there !

T30° => AD = AC/2 = 20cm/2 = 10 cm

T.Phytagoras

CD = √AC² - AD²

= √20² - 10²

= √400-100

= √300

= 10√3

= 10×1.73

= 17.3 cm

P = 2AD + 2CD

= 2×10cm + 2×17.3cm

= 20cm + 34.6cm

= 54.6 cm

Good luck !

Brett made a scale drawing of a rectangular room in his house.
The actual length of the room is 12 4/5 ft. The scale used to make the
drawing was 1/4 in. = 1 ft. What is the length, in inches, of the room
on the drawing?

Answers

Answer:

Step-by-step explanation:

Length of the room = 12 4/5 ft = 12.8 ft

Scale is 0.25 inches = 1 ft.

This means that every 1ft is shown as 1/4 inch on the map.

To find what 12 4/5ft on the map, you would multiply 12.8 by 0.25.

12.8 x 0.25 = 3.2 inches

x = -8

Step-by-step explanation:

using what's given, you can make the following equation:

3 + 22 + 2x - x = 17

25 + x = 17

x = 17 - 25

x = -8

Answer:

Step-by-step explanation:

3 + 2x + 22= x + 17

2x + 25 = x + 17

x + 25 = 17

x = -8

3 + 2(-8) + 22 = -8 + 17

Step-by-step explanation:

second one - for this one you would do 90 +30 = 120

then take this from 180 to get 60  . so if you can see  that  the shape is an f but that's if you take away the sides with the right angles . the corresponding angle rule (you can see an F shape) means that the angle that i just worked out is the same as angle c so angle c=60

third one - for this one do  70+30  then take this answer away from 180

that angle x

the rule for angle y is the vertically opposite angle rule   - angle s that are vertically opposite are the same  angle y= angle x - same angle

During the 2004 senatorial campaign in a large southwestern state, illegal immigration was a major issue. One of the candidates argued that illegal immigrants made use of educational and social services without having to pay property taxes. The other candidate pointed out that the cost of new homes in their state was 20–30% less than the national average due to the low wages received by the large number of illegal immigrants working on new home construction. A random sample of 5,500 registered voters was asked the question, "Are illegal immigrants generally a benefit or a liability to the state’s economy?" The results were as follows: 3,500 people responded "liability," 1,500 people responded "benefit," and 500 people responded "uncertain."
a. What is the population of interest?
b. What is the population from which the sample was selected?
c. Does the sample adequately represent the population?
d. If a second random sample of 5,000 registered voters was selected, would the results be nearly the same as the results obtained from the initial sample of 5,000 voters? Explain your answer.

Answers

Answer:

a

   The population of interest is the registered voters , this is because  it is the population from which the sample size is selected from.

b

The  population is the registered voters of the  large southwestern state

c

Well this does not adequately represent the population because this sample where selected from only the registered voters of the  large southwestern state  and not the whole country

d

   Yes the result will be nearly the same because

   Both samples are selected from the same population    The size of the  sample selected is sufficiently large to approximate      the population

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  5,500

Considering question a

 What is the population of interest

   The population of interest is the registered voters , this is because  it is the population from which the sample size is selected from.

Considering question b

What is the population from which the sample was selected    

  The  population is the registered voters of the  large southwestern state  

Considering question c

    Does the sample adequately represent the population

Well this does not adequately represent the population because this sample where selected from only the registered voters of the  large southwestern state  and not the whole country

Considering question d

   Yes the result will be nearly the same because

   Both samples are selected from the same population    The size of the  sample selected is sufficiently large to approximate      the population

Each person is represented by one line in the text file. The line starts with their ID number and after that, has the person's name. The lines are sorted by ID number in ascending order. There are n lines in this file. You write a search function that returns the name of a person whose ID number is given The simplest way to do that would be to program a loop that goes through each line and compares the ID number in the line against the given ID number. If there is a match, then it returns the name in that line. This is very inefficient, because the worst-case scenario is that this program needs to go through almost everyone the person we are looking for could be last. using the fact that he tli s sored wil greany speed up the processbus to use a birarysearch alkrhm We go to the middle line of the file first and compare the ID found there (P) to the given ID (Q). (f the number of lines is even, we go above or below the arithmetic middle.) if P=Q then our algorithm terminates . we have found the person we are looking for. If P is less than Q, that means that the person we are looking for is in the second half of the file. We now repeat our algorithm on the second half of the file. If P is greater than Q, that means that the person we are looking for is in the first half of the file. We now repeat our algorithm on the first half of the file.
