The coordinate of point P is (7/2, -13)
Midpoint of coordinatesThe formula for calculating the midpoint of coordinates is expressed as shown below:
M(x, y) = {(mx₁+nx₂)/2, (my₁+ny₂)/2}
Given the coordinate points A(-4, 2) and B(3, -6) divided in the ratio 2:5, then;
M(x, y) = {(2(-4)+5(3))/2, (2(2)+5(-6))/2}
M(x, y) = {-8+15)/2, (4-30)/2}
M(x, y) = {7/2, (-26)/2}
M(x, y) = (7/2, -13)
Hence the coordinate of point P is (7/2, -13)

Suppose a video store charges nonmembers $4 to rent each video. A store membership costs $21, and members pay only $2.50 to rent each video. For what number of videos is the cost the same?
Answers
Answer:
14 videos
Step-by-step explanation:
4n=21+2.5n
1.5n=21
n=21/1.5
n=14
Answer:
14 Videos
Step-by-step explanation:
Let x be the number of videos rentable.
From the information given from the question, we know that:
Case A: Non-members
Cost to rent videos = $4x
Case B: Members
Cost to rent videos = $(21 + 2.5x)
So given from the question, we can use:
4x = 21 + 2.5x to solve for x.
[tex]4x = 21 + 2.5x \\ 4x - 2.5x = 21 + 2.5x - 2.5x \\ 1.5x = 21 \\ x = \frac{21}{1.5} \\ = 14[/tex]

To subtract two fractions we need to have them have the same division by, which means the lower part of the fraction needs to be the same. To do that we would need to find a common denominator between 3 and 5, a number that can be both divided by 3 and 5. To figure common denominator for 5 and other nimbery just multiply the other number by 5: 3*5=15. so now we need to multiply both fractions by a number to get lower part to 15, so 4*3/5*3=12/15 and 1*5/3*5=5/15. Now we have 6 12/15 - 2 5/15 = 4 7/15.
A bag 2 contains 2 red marbles, 2 green marbles, and 4 blue marbles.
If we choose a marble, then another marble without putting the first one back in the bag, what
is the probability that the first marble will be red and the second will be green?
Answers
The value of the probability is 0.0714.
According to the statement
We have to find that the students' favorite color was red.
So, For this purpose, we know that the
Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
From the given information:
A bag 2 contains 2 red marbles, 2 green marbles, and 4 blue marbles.If we choose a marble, then another marble without putting the first one back in the bag.
Then
A bag contains 2+2+4=8 marbles in total.
We have to search out the probability of the subsequent events:
1. we've to settle on a red marble from the bag that contains 8 marbles in total, 2 of them are red
2. we've to decide on a green marble from the bag that contains 7 marbles in total, 2 of them are green.
The probability of the primary event to happens is:
P(one) = 2/8 = 1/4.
The probability of the second event to happen is:
P(two) = 2/7
The probability of both events to happen is:
P = P(one) * P(two)
P = 1/4 * 2/7
P = 1/14
P = 0.0714.
So, The value of the probability is 0.0714.

Difference in math is the result of one of the important mathematical operations, which is obtained by subtracting two numbers. It tells us by how much a number differs from the other. The aim of finding the difference in math is to tell how many numbers lie between the two given numbers.
Set difference is a generalization of the idea of the complement of a set and as such is sometimes called the relative complement of T with respect to S. The symmetric difference between two sets S and T is the union of S – T and T – S.
Based on the conditions, formulate :
Let us assume,
The difference between value = x
We can write,
x = 9493 - 2324
Calculate the sum or difference,
x = 7169.

Suppose that 27 slips of paper numbered 1 to 27, inclusive, are put into a hat. Then one is drawn out at random. Find the probability of getting slip 12 and even numbers and prime numbers
Answers
The probability of getting-
slip 12 = 1/27even numbers = 13/27, andprime numbers = 1/3.What is meant by probability?Probability is the measure of how likely an event is to occur. Many events are impossible to predict to absolute certainty. We can only predict the possibility of an event occurring, i.e. how likely it is to occur, using it.
The formula for probability is;
Probability(event) = favourable outcome/ total outcome
Now, as per the given question;
There are 27 papers put in a hat numbering from 1 to 27.
The sample space will be;
s = {1,,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27}
The total outcome is 27.
The total number of 12 digit in the sample space is 1.
Thus, the probability for getting slip 12 is;
Probability(slip 12) = 1/27
The sample space for even number are;
s = {2,4,6,8,10,12,14,16,18,20,22,24,26}
Now, there are total number of even digits in the sample space is 13.
Thus, the probability for getting even number is;
Probability(even) = 13/27.
The sample space for prime number are;
s = {2,3,5,7,11,13,17,19,23}
Noe, the total number of prime digits in the sample space is 9.
Thus, the probability for getting prime number is;
Probability(prime) = 9/27 = 1/3
Therefore, the probability for getting the prime number is 1/3.

A bank charges 12% Simple interest p.a on cash loans to its clients.tito has asked for R10000loan amount and has promised to repay the the loan over 4years
Calculate the interest which Tito has to pay on loan ?
Determine the total amount to be paid back
Determine the monthly repayment amount
Answers
If Tito took a loan of $10000 from a bank to be repaid within 4 years, at 12% Simple interest per annum, then, he will have to pay overall $4800 as interest to the bank over 4 years and a total payment of $14800 at the end of the 4th year to repay and close off the loan.
As per the question statement, a bank charges 12% Simple interest per annum on cash loans to its clients and Tito took a loan of $10000 from the same bank to be repaid within 4 years.
We are required to calculate the overall interest Tito has to pay to bank if he repays and closes the loan at the end of 4th year, and also to calculate the total payment required to repay and close off the loan at the end of the 4th year.
To solve this question, we need to know the formula to calculate the interest amount in case of simple interest which goes as
Interest (I) [tex]=(\frac{P*R*T}{100} )[/tex]
where, "P" = Principle amount of Loan,
"R" = Rate of simple interest charged on the principle per annum, and
"T" = Time period within which, the loan is to be repaid.
Here, (P = 10000), (R = 12%) and (T = 4). Then, the overall interest Tito will have to pay at the end of 4th year = [tex](\frac{10000*12*4}{100}) = (100*12*4)=(48*100)=4800[/tex]
And total amount to be paid to repay and close of the loan at the end of 4th year will be = $[4800 + 10000] = $14800.

How to determine the cost of the labor per hour?
Here we know that they charged a total of $249.75, and the cost in parts was $181, then the cost in labor is:
$249.75 - $181 = $68.75
And we know that they worked for 2.75 hours, the cost per hour is given by the quotient between the cost in labor and the number of hours, then we can get:
$68.75/2.75 = $25
