A line segment with one end at A (-3,2) has midpoint M (2,-3). Find the coordinate of the other end point B.
(A.) B (-1,-1)
(B.) B (5,-5)
(C.) B (1,-4)
(D.) B (7,-8)
Answer:
D
Step-by-step explanation:
since all x coordinates are distinct, lets just find the x coordinate (multiple choice question)
Midpoint formula:
given two points, (x1, y1) and (x2, y2)
the midpoint is ((x1+x2)/2, (y1+y2)/2)
-3+x2 = 2*2
x2 = 7

Which of the following sampling methods would be most likely to result in nonresponse bias? O A. Handing out a questionnaire to seniors only 0 B. Obtaining an alphabetical list of all students and surveying every 10th student O C. Setting up a booth in the lunchroom where students can give their thoughts D. Handing out a questionnaire to students leaving campus at lunchtime
Answer:
C. Setting up a booth in the lunchroom where students can give their thoughts
Step-by-step explanation:
Sampling is the process by which some part of the entire population is selected and researched. This selected population helps in estimating the researches for the entire population. There are various methods used for the process of sampling.
For the given case, the sampling method to be adopted is to view each students' opinion on the issue. For this process, setting up a booth can prove helpful as the opinion of every student can be viewed with no biases. Also, every student is free to provide their opinion with any fear.
In which step was the addition property of equality applied? A. step 2 B. step 3 C. step 4 D. The addition property of equality was not applied to solve this equation.
Answer:
Step 2
Step-by-step explanation:
The addition property of equality was applied in step 2. The '- 9' value had to be 'undone', so '9' was added to each side of the equation, which would be an application of the addition property of equality, to yield step 3.
Hope this helps.
The correct option is A. Step 2.
Given the image in question as we saw in step 2, 9 has been added to both sides of the equation,right hand side and left hand side.
Hence in step 2 the addition property of equality applied.
So, the correct option is A. step 2.

How many ways can six of the letters of the word ALGORITHM be selected and written in a row if the first three letters must be THM
Answer: 120 ways
Step-by-step explanation: The word ALGORITHM has 9 letters. We want them to be written in a row, which means, order of the letters are important, so, use Permutation.
Permutation is calculated by:
P(n,r) = [tex]\frac{n!}{(n-r)!}[/tex]
We want to use 6 of the 9 letters with first 3 being THM. So, n = 6 and r = 3:
Permutation will be:
P(6,3) = [tex]\frac{6!}{(6-3)!}[/tex]
P(6,3) = [tex]\frac{6.5.4.3!}{3!}[/tex]
P(6,3) = 120
There are 120 ways six letters of ALGORITHM be written in a row with first three letters THM.

Answer:
a). $8.30
b).$18.70
c). $10.40
d). 1.04
Step-by-step explanation:
Average price of the ticket of a basketball game can be represented by the function,
p(x) = 0.03x² + 0.56x + 6.35
Where 'x' is the number of years or duration.
a). P(3) = 0.03(3)² + 0.56(3) + 6.35
= 0.27 + 1.68 + 6.35
= $8.30
b). P(13) = 0.03(13)² + 0.56(13) + 6.35
= 5.07 + 7.28 + 6.35
= $18.70
c). P(13) - P(3) = 18.70 - 8.30
= $10.40
d). [tex]\frac{P(13)-P(3)}{13-3}[/tex] = [tex]\frac{10.40}{10}[/tex]

Tony rounded each of the numbers 1,143 and 1,149 to the nearest hundred. Which choice correctly compares the rounded numbers?
The rounding off should be 1100.
What is rounding off?Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
Rounding Numbers to the Nearest HundredRounding numbers to the nearest hundred means we need to check the digit to the right of the hundreds place, that is, the tens place. For example, when 7456 is rounded to the nearest hundred, it becomes 7500.
Given numbers are 1143 and 1149.
According to the given numbers both the numbers rounded off nearest hundred.
The number 143 and 149 lies between 100 to 200.
So, the round off will be 100.

ANSWER IF YOU LOVE YOUR LORD!!!! Which graph represents the solution to: 2k+8<5k-1?
Answer:
Third graph
Step-by-step explanation:
First, find the solution to the equation of inequality given.
2k + 8 < 5k - 1
Subtract 5k from both sides
2k + 8 - 5k < 5k - 1 - 5k
-3k + 8 < -1
Subtract 8 from both sides
-3k + 8 - 8 < -1 - 8
-3k < -9
Divide both sides by -3. (Note: < will change to > when dividing both sides with negative number)
[tex] \frac{-3k}{-3} [/tex] > [tex] \frac{-9}{-3} [/tex]
k > 3
The graph that will represent this solution will show that all values of k are greater than 3. 3 is not included as a solution. The "o" on top of the 3 on the number line won't be shaded to indicate that 3 is not included. And also, the arrow will point from 3 towards our right.
Therefore, the 3rd graph is the answer.

Answer:
4.0
Step-by-step explanation:
when rounded the nine adds to the whole number making it 4
Rounding 3.99408317124 to nearest tenth becomes 4.
Why we round numbers ?We round numbers as it is easy to remember and also rounding a number to a certain place retains approximate value to that pace.
According to the given question we have to round 3.99408317124 to nearest tenth.
We know to round a number to a certain place we have to check the
digit that is one place lesser.
Now we have to round 3.99408317124 to tens place so we'll look at the digit at ones' place which is 9 and is greater than 5 so we'll add one to it this will make it 0 and 1 will carry over.

Find the inverse of the exponential function f(x)=10^x
Answer: [tex]y=\frac{ln(x)}{ln(10)}[/tex]
Step-by-step explanation:
To find the inverse of the function, you first replace the y with x and x with y. Then you solve for y.
[tex]y=10^x[/tex] [replace y with x and x with y]
[tex]x=10^y[/tex] [find natural log of both sides to get y alone]
[tex]ln(x)=ln(10)^y[/tex] [divide ln(10) on both sides]
[tex]\frac{ln(x)}{ln(10)} =y[/tex]
Now that we have found y after switching y with x and x with y, we know that the inverse is [tex]y=\frac{ln(x)}{ln(10)}[/tex].

A, B and C together can finish a piece of work in 4 days, A alone can do it in 12 days and B alone in 18 days. How many days will be taken by C to do it alone?
Answer:
9 days
Step-by-step explanation:
Let x = days taken by C to do it alone
In one day, A can do: 1/12 (part of the whole work)
In one day, B can do: 1/18 (part of the whole work)
In one day, C can do: 1/x (part of the whole work)
In one day,together A, B and C can do: 1/4 (part of the whole work)
we have this equation:
1/x + 1/12 + 1/18 = 1/4
--> 1/x = 1/4 - 1/12 - 1/18 = 1/9
--> x = 9 (days)

Phillip deposited $7,775 into a savings account 14 years ago. The account has an interest rate of 4.5% and the balance is currently $14,398.87. How often does the interest compound? (2 points)
daily
monthly
quarterly
annually
Answer:
annually
Step-by-step explanation:
Compound interest formula:
A = P(1 + r/n)^(nt)
amount of interest = balance - principal
Try daily:
A = 7775(1 + 0.045/365)^(365 * 14)
A = 14,597.88
This is too much money, so it was compounded less than daily.
Try monthly:
A = 7775(1 + 0.045/12)^(12 * 14)
A = 14,581.23
This is too much money, so it was compounded less than monthly.
Try quarterly:
A = 7775(1 + 0.045/4)^(4 * 14)
A = 14,547.16
This is too much money, so it was compounded less than quarterly.
Try annually:
A = 7775(1 + 0.045/1)^(1 * 14)
A = 14,398.87
This is the correct amount, so it was compounded annually.
Answer: annually

find the sum and difference of the greatest and the least six digit number formed by the digits 2,0,4,7,6,5 using each digit only once
Answer:
See below
Step-by-step explanation:
The greatest number formed by those numbers is: 765420
The least number formed by those number is: 204567
The sum is: 765420 + 204567 = 969987
The difference is: 765420 - 204567 = 560853
Answer: Hi!
First we need to form the biggest and smallest number out of these digits. To do this it's pretty simple - just order the numbers from greatest to least for the greatest number, and from least to greatest for the least number! (However, for the least number, we will have to put the zero in front of 2, the second least number, because we can't put 0 in front of 2 and still be actually using it in the number.)
Greatest: 765420
Least: 204567
Now we add the numbers together:
765420 + 204567 = 969987
Now we subtract the numbers:
765420 - 204567 = 560853
These are your answers!
