One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?
Answer:
One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?
Step-by-step explanation:
Let us suppose two years ago my brother's age was x years
Then, my age was 3x
Three years from now, my brother's age will be (x +2+3) = (x+5) years
And my age will be (3x+2+3) = (3x+5) years
But it is given that i will be twice as old as my brother.
So, 2(x+5)= (3x+5)
or, x= 5 years
So my brother's present age is 5+2= 7 years
And my age is 5*3+2= 17 years
The age of the older brother is 13 and the age of the younger brother is 5.
Two simultaneous equations can be determined from this question:
y = 3x - 2 equation 1
y = 2x + 3 equation 2
Where:
y = older brother's age
x = younger brother's age
Equate equation 1 and equation 2
3x - 2 = 2x + 3
Combine similar terms
3x - 2x = 3 + 2
x = 5
Substitute for x in equation 1
3(5) - 2
15 - 2
y =13

A storage pod has a rectangular floor that measures 21 feet by 9 feet and a flat ceiling that is 7 feet above the floor. Find the area of the floor and the volume of the pod.
Answer:
area: 189 ft²volume: 1323 ft³Step-by-step explanation:
The area of the rectangular floor is the product of its length and width:
A = LW = (21 ft)(9 ft) = 189 ft²
The volume of the pod is the product of that floor area and the height:
V = Bh = (189 ft²)(7 ft) = 1323 ft³
The area of the floor is 189 ft²; the volume of the pod is 1323 ft³.
A distribution is negatively skewed. Which is the most probable order for the three measures of central tendency
Options :
a mean - 40, median - 50, mode - 60
b. mean-60, median - 50, mode - 40
c. mean - 40, median-60, mode - 50
d. mean - 50, median - 50, mode - 50
Answer: mean - 40, median - 50, mode - 60
Step-by-step explanation: A negatively skewed distribution is characterized by it long tail being positioned to the left(negative direction) with its peak positioned to the right (positive direction) of the distribution. On a general note, the mean is always positioned towards the left or negative side if the peak, with the median coming next and usually positioned to the right of the mean and the mode positioned to the right side of the median.
Hence, for a negatively skewed distribution, the mean has the least value followed by the median, with the mode boasting the highest.
That is : mean < median < mode

g The false positive rate, P(+|N), for a test is given as 0.04. What is the specificity for this test?
Answer:
Step-by-step explanation:
Let us consider a data of prevalent diseases.
If the false positive rate is P(Test + | N) = 0.04
Therefore, sensitivity is defined as the probability of a positive test result given the presence of the disease. This can be written as: P (positive test | disease present).
Specificity is defined as the probability of a negative test result given absence of disease, that is, P (negativetest | diseaseabsent). PPV is defined as the probability of the presence of disease given a positive test result, ie, P (disease present | positivetest).

You own 24 CDs. You want to randomly arrange 7 of them in a CD rack. What is the probability that the rack ends up in alphabetical order
Answer:
the probability that the rack ends up in alphabetical order is 0.0001984
Step-by-step explanation:
Given that:
You own 24 CDs. You want to randomly arrange 7 of them in a CD rack.
Th probability that the rack ends up in alphabetical order can be determined by taking note of the permutations and combinations.
From above; all possible permutations of size 7 we can derive from 24 is
24P7
Similarly,we are meant to estimate all the possible ways a unique set of 7 things can be gotten from a total of 24
i.e
24 C7
∴
The probability = [tex]\dfrac{^{24}{C}_7}{^{24}{P}_7}[/tex]
= [tex]\dfrac{\dfrac{24!}{7!(24-7)!} }{ \dfrac{24!}{(24-7)!} }[/tex]
=[tex]\dfrac{\dfrac{24!}{7!(17)!} }{ \dfrac{24!}{(17)!} }[/tex]
= [tex]\dfrac{346104}{ 1.74436416 \times 10^9}[/tex]
= 0.0001984
the probability that the rack ends up in alphabetical order is 0.0001984
The probability that the rack ends up in alphabetical order is 0.0001984
The total number of CD is given as:
[tex]\mathbf{n = 24}[/tex]
The number of CDs to select is given as:
[tex]\mathbf{r = 7}[/tex]
The number of arrangement of 7CDs in 24 is represented as 24P7
So, we have:
[tex]\mathbf{^{24}P_7 = \frac{24!}{(24 - 7)!}}[/tex]
[tex]\mathbf{^{24}P_7 = \frac{24!}{17!}}[/tex]
Simplify
[tex]\mathbf{^{24}P_7 =1744364160}[/tex]
The number of selecting 7 CDs from 24 is represented as 24C7
So, we have:
[tex]\mathbf{^{24}C_7 = \frac{24!}{(24 - 7)!7!}}[/tex]
[tex]\mathbf{^{24}C_7 = \frac{24!}{17!!7}}[/tex]
Simplify
[tex]\mathbf{^{24}C_7 =346104}[/tex]
So, the probability is:
[tex]\mathbf{Pr = \frac{346104}{1744364160}}[/tex]

The product of two whole numbers is 936 and the sum is 62. What are the two numbers
Answer:
26 and 36.
Step-by-step explanation:
Let the two whole numbers be a and b. Thus, the product of them is 936 while their sum is 62. In equations, this is:
[tex]ab=936\\a+b=62[/tex]
This is a system of equations. To solve, subtract either a or b from the second equation and substitute it into the first.
For instance, subtract b from both sides in the second equation:
[tex]a+b=62\\a=62-b[/tex]
Substitute this into the first equation:
[tex](62-b)(b)=936[/tex]
Distribute:
[tex]62b-b^2=936[/tex]
Rearrange:
[tex]-b^2+62b=936[/tex]
Divide everything by -1 to make the leading coefficient positive:
[tex]b^2-62b=-936[/tex]
Add 936 to both sides:
[tex]b^2-62b+936=0[/tex]
This is now a quadratic. Solve for b.
To do so, we can factor.
After a bit of testing, we can see that -36 and -26 are possible. Thus:
[tex](b-26)(b-36)=0[/tex]
For for b:
[tex]b=26\text{ or } b=36[/tex]
Thus, b is 26 or 36.
Now, plug these back into the isolated equation to solve for a:
[tex]a=62-b\\a=62-(26) \text{ or } a=62-(36)\\a=36\text{ or } a=26[/tex]
It doesn't really matter which one we choose since they're the same.
Thus, the answer is 26 and 36.

If there are 17.5 grams of sugar in 225 grams of an aqueous sugar solution, the percent-mass sugar is ______ and the percent-mass water is ______ . Express both answers to the correct number of significant figures.
Answer:
7.77%(m/m) ; 92.22%(m/m)
Step-by-step explanation:
Given that:
17.5 grams of sugar in 225 grams of an aqueous sugar solution
Percentage by mass of A in a solution (mass percent) = (mass of A / total mass of solution) × 100
Hence,
Percentage by mass of sugar:
= (mass of sugar / total mass of solution) * 100
= (17.5 / 225) × 100
= 0.0777777 × 100 = 7.77%(m/m)
Mass of water(solvent) = (225 - 17.5)g = 207.5g
= (207.5 / 225) × 100
= 0.922222 × 100 = 92.22%(m/m)
List the new coordinate of point J' when the figure is reflected over the y-axis.
Answer: (-4, -3)
Step-by-step explanation:
The original coordinate of J is (4, -3)
Since it is reflex over y-axis, the y value remains.
For the x value, it is originally 4 units away from the y-axis positively, thus, after reflexing, it will be 4 units away from the y-axis negatively.
