Answer:
20 + 14 = 34, there there are only 29 students, so 34 - 29 or 5 have both a dog and a cat
15 have only a dog
5 have a dog and a cat
9 have only a cat
Step-by-step explanation:
The probability that a student has a cat given that they do not have a dog is 3/5
What is probability ?Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen.
According to the question,
The number of student who do not have a dog is
25 - ( 8 + 2 ) = 15
9 have a cat { do not have a dog is a prerequisite }
So the probability that a student has a cat given that they do not have a dog = 9/15
= 3/5

If the interest of sum of money is 6 yrs in 3/8 of the principal . what is the rate of interest?
Given that,
The interest of sum of money is 6 yrs in 3/8 of the principal.
To find,
The rate of interest.
Solution,
Let P is the principal. It means interest will be :
I=3/8 P
The formula for the interest is given by :
[tex]I=\dfrac{PRT}{100}\\\\\dfrac{3}{8}P=\dfrac{PR\times 6}{100}\\\\\dfrac{3}{8}=\dfrac{6R}{100}\\\\R=\dfrac{300}{8\times 6}\\\\=6.25\%[/tex]
Hence, the rate of interest is 6.25%.

The population of Garden City in 1995 was 2,400. In 200, the population was 4,000. Write a linear equation in slope-intercept form that represents this data.
Answer:
[tex]y = 320x +2080[/tex]
Step-by-step explanation:
Given
Population in 1995 = 2400
Population in 2000 = 4000
Required
Determine the linear equation
Let the years be represented with x.
In 1995, x = 1 i.e. the first year
In 2000, x = 6
Let y represents the population
When x = 1; y = 2400
When x = 6; y = 4000
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{4000 - 2400}{6 - 1}[/tex]
[tex]m = \frac{1600}{5}[/tex]
[tex]m = 320[/tex]
Next, we calculate the line equation as follows:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 2400 = 320(x - 1)[/tex]
[tex]y - 2400 = 320x - 320[/tex]
[tex]y = 320x - 320 + 2400[/tex]
[tex]y = 320x +2080[/tex]

Lamar is considering two loans.
Loan A
Loan B
Principal
$4,500
$4,300
Interest rate
5%
6%
Time in years
3
3
Which loan will have the lowest total payback?
Step-by-step explanation:
know:
Loan A
Principal
$4500
Interest rate
5%
Time in years
3
If 100% => $4500
5% =>X
X = 5% × $4500 ÷ 100% = $225
Loan A = $4500 + $225 = $4725
Loan B
Principal
$4300
Interest
6%
Time in years
3
If 100% => $4300
6% =>X
X = 6% × $4300 ÷ 100% = $258
Loan B = $4300 + $258 = $4558
Loan B has the lowest total payback.
The Loan B has the lowest total payback than the Loan A.
How to calculate the Payback?WE can calculate the payback in both loan as;
Loan A;
Principal = $4500
Interest rate = 5%
Time in years = 3
If 100% => $4500
X = 5% × $4500 ÷ 100%
X = $225
Loan A = $4500 + $225 = $4725
Loan B;
Principal = $4300
Interest = 6%
Time in years = 3
If 100% => $4300
X = 6% × $4300 ÷ 100%
X= $258
Loan B = $4300 + $258 = $4558
Hence, the Loan B has the lowest total payback than the Loan A.

Step 1: Define
q = d / (d + n)
Step 2: Solve for d
Multiply (d + n) on both sides: q(d + n) = dDistribute q: dq + qn = dSubtract qn on both sides: dq = d - qnSubtract d on both sides: dq - d = -qnFactor GCF: d(q - 1) = -qnDivide (q - 1) on both sides: d = -qn / (q - 1)Rearrange: d = nq / -(q - 1)Distribute -1: d = nq / 1 - qIn a class of 12 boys and 8 girls, two students need to be chosen for classroom jobs.

There is a cool trick you can do. Lets take 28 and square it.
First you round the number up. 28 rounded is 30. You rounded up by 2 (30-28=2) so you minus 2 from 28.
You are left with these two numbers, 26 and 30. Add a zero to the 26.
You now have 260 and 3 (you remove 0 on the 30 since you added it to the 26)
Then you multiply by 3.
260x3=780
Then you add the square of the number you rounded up too, which is 2.
You are left with this equation.
(2^2)+780= 784
28x28=784.
This works for numbers below 100 and integers
