A family buys a studio apartment for $240,000. They pay a down payment of $60,000.
a. Their down payment is what percent of the purchase price?
b. What percent of the purchase price would a $96,000 down payment be?
Answer:
Part A: 25%
Part B: 40%
Step-by-step explanation:
Given the following questions:
$240000 for a studio apartment
$60000 as a down payment.
In order to find the answer, we use the formula to calculate the percentage for the total cost of the studio apartment and the down payment.
Part A:
[tex]\frac{c\times n}{100}[/tex]
[tex]\frac{25\times240000}{100} =25\times240000=60000[/tex]
[tex]=60000[/tex]
Part B:
[tex]\frac{c\times n}{100}[/tex]
[tex]\frac{40\times240000}{100} =40\times240000=9600000\div100=96000[/tex]
[tex]=96000[/tex]
The percent of a down payment of $60,000 for a $240,000 studio apartment is "25%." While the percent of a $96,000 dollar down payment for a $240,000 studio apartment is "40%."

Four rats are selected at random from a cage of 5 male (M) and 6 female (F) rats. If the random variable Y is concerned with the number of female rats taken out of the cage, construct the probability distribution and answer the questions below. (input up to 4 decimal places)A What is the probability that all selected rats are female?
What is the probability that only one of the selected rats is female?
c. What is the probability that at least two of the selected rats is female?
What is the mean of the probability distribution?
E. What is the standard deviation of the probability distribution?
Using the hypergeometric distribution, it is found that the distribution is:
P(X = 0) = 0.0152
P(X = 1) = 0.1818
P(X = 2) = 0.4545
P(X = 3) = 0.3030
P(X = 4) = 0.0455
Hence:
A) There is a 0.0455 = 4.55% probability that all selected rats are female.
B) There is a 0.1818 = 18.18% probability that only one of the selected rats is female.
C) There is a 0.803 = 80.3% probability that at least two of the selected rats is female.
D) The mean of the probability distribution is of 2.18.
E) The standard deviation of the probability distribution is of 0.833.
The rats are chosen without replacement, hence the hypergeometric distribution is used to solve this question.
What is the hypergeometric distribution formula?The formula is:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.In this problem:
There is a total of 11 rats, hence N = 11.6 of the rats are female, hence k = 6.4 rats are taken, hence n = 4.The distribution is the probability of each outcome, hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,11,4,6) = \frac{C_{6,0}C_{5,4}}{C_{11,4}} = 0.0152[/tex]
[tex]P(X = 1) = h(1,11,4,6) = \frac{C_{6,1}C_{5,3}}{C_{11,4}} = 0.1818[/tex]
[tex]P(X = 2) = h(2,11,4,6) = \frac{C_{6,2}C_{5,2}}{C_{11,4}} = 0.4545[/tex]
[tex]P(X = 3) = h(3,11,4,6) = \frac{C_{6,3}C_{5,1}}{C_{11,4}} = 0.3030[/tex]
[tex]P(X = 4) = h(4,11,4,6) = \frac{C_{6,4}C_{5,0}}{C_{11,4}} = 0.0455[/tex]
Item a:
P(X = 4) = 0.0455, hence:
There is a 0.0455 = 4.55% probability that all selected rats are female.
Item b:
P(X = 1) = 0.1818, hence:
There is a 0.1818 = 18.18% probability that only one of the selected rats is female.
Item c:
[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.4545 + 0.3030 + 0.0455 = 0.803[/tex]
There is a 0.803 = 80.3% probability that at least two of the selected rats is female.
Item d:
The mean of the hypergeometric distribution is:
[tex]\mu = \frac{nk}{N}[/tex]
Hence:
[tex]\mu = \frac{4(6)}{11} = 2.18[/tex]
The mean of the probability distribution is of 2.18.
Item e:
The standard deviation of the hypergeometric distribution is:
[tex]\sigma = \sqrt{\frac{nk(N-k)(N-n)}{N^2(N-1)}}[/tex]
Hence:
[tex]\sigma = \sqrt{\frac{4(6)(11-6)(11-4)}{11^2(11-1)}} = 0.833[/tex]
The standard deviation of the probability distribution is of 0.833.

The functions f(x) and g(x) are defined below.
f(x) = -20x + 11
g(x) = -19x + 3
Using a table of values, determine the solution to the equation f(x) = g(x).
A. x = -149
B. x = 14
C. x = 8
D. x = -8
Answer:
x = 8
Explanation:
f(x) = g(x)
Given:
f(x) = -20x + 11g(x) = -19x + 3solve:
-20x + 11 = -19x + 3
-20x + 19x = 3 - 11
-x = -8
x = 8

Hi can someone plss help me turn this equation into standard form (I don't really know how)
Answer:
2x - 4y = 8
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
4y = 2x - 8 ( subtract 2x from both sides )
- 2x + 4y = - 8 ( multiply through by - 1 )
2x - 4y = 8 ← in standard form
The angle of depression of a boat from three quarters of a vertical pole is 35º. If the boat is 120 m from the foot of the pole, calculate the height of the pole.
Answer:
112 m
Step-by-step explanation:
The angle of depression from the pole position is the same as the angle of elevation from the boat position. So, the problem statement gives us an angle and horizontal and vertical legs of a right triangle. The relation between them is given by the tangent function.
Tan = Opposite/Adjacent
If we let (3/4h) represent the length of the side opposite the given angle, and 120 m the side adjacent, we have ...
tan(35°) = (3/4h)/(120 m)
Multiplying by the inverse of the coefficient of h, we get ...
h = (160 m)tan(35°) ≈ 112 m
The height of the pole is about 112 meters.
Harry Potter is trying to figure out how many potions he needs to learn to get an A in Severus Snape’s class. Every time he makes 4 potions, his grade goes up by one letter. He can earn an F, D, C, B, or A. If he has has a D in the class, how many more potions does Harry need to make to get an A?
Answer:
Harry needs to make 12 potions to get an A.
Step-by-step explanation:
He currently has a D
+ 4 = C
+ 4 = B
+ 4 = A
4 + 4 + 4 = 12 potions
So, Harry needs to make 12 potions to get an A in his potions class.

The average marks obtained by three students is 15. If two students obtained 12 and 18 marks respectively, find the marks obtained by the third student.
Answer:
15 marks
Step-by-step explanation:
If the average mark obtained by 3 students is 15, then the total marks are
⇒ 3 x 15 = 45
Let x be the marks obtained by the third student.
If two students obtained 12 and 18 marks, then
⇒ 12 + 18 + x = 45
⇒ 30 + x = 45
⇒ x = 45 - 30
⇒ x = 15
Solution:
We can clearly say that "mean" has been used.
Mean is the average of a group of numbers.In this case, we are given three numbers, 12, x, and 18.
=> 12 + 18 + x/3 = 15=> 30 + x = 3 x 15=> 30 + x = 45=> x = 45 - 30=> x = 15The marks obtained by the third student is 15 marks.

Jayden needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 3.75 hours and charged him $60 for parts. The total was $528.75. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Answer:
$125 and hour - (528.75 - 60) / 3.75
Step-by-step explanation:
Since the total includes the $60 for the parts, we have to subtract 60 from 528.75. Once we've found the difference (468.75), we can divide by the amount of hours (3.75). That leaves us with the answer, $125.
