The mean age of 5 people in a room is 25 years.
A person enters the room.
The mean age is now 27.
What is the age of the person who entered the room?
Answer:
37 years
Step-by-step explanation:
If the mean age of 5 people in that room was 25 years,
∴ Sum₍₅₎= (25×5)years
= 125 years
When a person enters that room, the mean age was now 27.
∴ Sum₍₆₎=(27×6) years
= 162 years
∴ The age of the person who entered the room = Sum₍₆₎ - Sum₍₅₎
= (162-125) years
= 37 years
∴ The age of the person who entered the room is 37 years.
Hope this helps!!!

Enter the value of 7.(2+18) -14
Answer:
we are going to use BODMAS
7.(2+18) -14
is also 7×(2+18) -14
since B representing bracket comes first,
we add the numbers in the bracket.
2+18=20
7×(20) -14
then M representing multiplication comes next do we multiply.
7×20=140
140-14=126
that's it!
C-12.1 Binomial coefficients are a family of positive integers that have a number of useful properties and they can be defined in several ways. One way to define them is as an indexed recursive function, C(n, k), where the "C" stands for "choice" or "combinations." In this case, the definition is as follows: C(n, 0) = 1, C(n, n)=1, and, for 0
Answer:
Step-by-step explanation:
a)
If we implement the combinations recursively without memoization, then the running time would be exponential in n.
Time Complexity:
If we implement this equation literally, as a recursive program, then the running
time of our algorithm without using memoization, T(n), as a function of n, has the following behavior:
T(0) = 1
T(1) = 1
T(n) = T(n − 1) + T(n − 2).
But this implies that
T(n) ≥ 2T(n − 2) = 2^(n/2).
b)
But if we store the combinations in an array, C[][], then we can instead calculate the combinations, C(n,k), iteratively, as follows:
C[0,0] = 0
C[1,1] = 1
for i = 2 to n do
C[n,k] = C[n-1, i−1] + C[n-1,k]
This algorithm clearly runs in O(n) time, and it illustrates the way memoization
can lead to improved performance when subproblems overlap and we use table
lookups to avoid repeating recursive calls.

If the cake you want regularly costs $9, how much would you save with the discount?
Step-by-step explanation:
The offer is 25% sale on cupcakes
Single cake costs = 9
25% = 0.25
After discount the price of cake = 9 x 0.25 = 2.25
Aloysius and Benjamin have $150 altogether. Aloysius' mother gives him another $40 and Benjamin spends $ 10 on a book. Benjamin then has $10 more than Aloysius . How much money does each of them have at first?
Answer:
Aloy has $55 initially
Benjamin has $95 initially
Step-by-step explanation:
In this question, given the order in which the money flowed in the question, we want to know how much each of the two had initially.
let what Aloys have be x and what Benjamin has be y.
Together, they had 150
x + y = 150 ••••••••(i)
Aloys mother gave him 40, new money is x + 40, Benjamin spent 10, new money is y-10
the new difference is 10
Thus;
(x + 40)-(y-10) = 10
x + 40 -y + 10 = 10
x+ 40 = y
substitute this into the first equation
x + 40 + x = 150
2x + 40 = 150
2x = 150-40
2x = 110
x = 110/2
x = $55
y = x + 40 = 55 + 40 = $95

Answer:
P(red) = .3
P(yellow) = .3
75 cubes in the box
Step-by-step explanation:
The probability has to add to 1
Since the number of red cubes equals the number of yellow cubes the probability has to be the same
.4 + x+x = 1
.4 +2x = 1
2x = 1-.4
2x = .6
Divide by 2
x = .6/2
x = .3
P(red) = .3
P(yellow) = .3
We know that
P(blue) = .4 = number of blue cubes/ total number of cubes
.4 = 30/total
total = 30/.4
total = 75

Answer:
RC1. 5
RC2. 8
RC3. a
RC4. 3
Step-by-step explanation:
So basically what you need to start with is the fact that the second triangle is 2 times larger than the first.
so,
8 = 8
C = 10
A = 6
---------------------------------------------------------------------
the next important part is that the opposite sides of the fraction, when multiplied are equal to each other.
( for example 1/2 = 2/4, because 1*4 = 4 and 2*2 = 4)
RC1. a/3 = C/_
substitute
6/3 = 10/_
3 * 10 = 30
6 * _ =30
30/6 = 5.
Rc2. 4c = 5_
4*10 = 5*_
40/5 = 8
RC3. 3c = 5*_
3*10 = 5*_
30/5 = 6
RC4. 4a = 8*_
4 * 6 = 8*_
24/8 = 3

Create a data set of six values that meet the following criteria...
Mean: 6
Range: 7
Mode: 3
Median 6
Answer: A = {2, 6 ,6 , 6 , 7 ,9}
Step-by-step explanation:
As the mode is 3, we must have a number that repeats 3 times.
As the median is 6, the number in the middle must be 6
then with this we can construct a set with 3 times the number 6.
Now, knowing that the range is 7. the difference between the larger number and the smaller number is 7, so suppose the larger number is 9 and the smaller number is 2 (9 - 2 = 7)
Then the numbers in our set are:
2 6 6 6 9
lets find the last one.
We know that the mean is 6, then we have
6 = (1/6)*( 2 + 6 + 6 + 6 + 9 + x) = (1/6)(29 + x)
6*6 = 29 + x
36 - 29 = x
x = 7
Then our set is:
A = {2, 6 ,6 , 6 , 7 ,9}
Where the number in the middle is 6, the mean is 6, the mode is 3 and the range is 7
What is 24% as a growth and decay factor
Answer:
When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1. In general if r represents the growth or decay factor as a decimal then: b = 1 - r Decay Factor. b = 1 + r Growth Factor. A decay of 20% is a decay factor of 1 - 0.20 = 0.
Step-by-step explanation:
The growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.
What is the growth and decay factor?It is defined as the factor that represents the increase and decreases in value by that factor. For the growth add one as a decimal and for the decay subtract one as a decimal.
For the growth factor:
F(g) = 1+r
Here r = 24% = 0.24
F(g) = 1+0.24 = 1.24
For the decay factor:
F(d) = 1-r
Here r = 24% = 0.24
F(d) = 1-0.24 = 0.76
Thus, the growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.

Find the approximate area of /CDE. A. 48.3 square units B. 59.8 square units C. 64.6 square units D. 75 square units
Triangle:
Line CE =15
Line ED =12
Line CD =10
Answer:
B
Step-by-step explanation:
To calculate the area of this triangle we can use the Heron’s formula
Mathematically we have the Heron’s formula as;
A = √s(s-a)(s-b)(s-c)
where s = (a + b + c)/2
Thus, s = (15 + 12+ 10)/2 = 18.5
a = 15, b = 12 and c = 10
Plugging these values into the equation, we have
√18.5(18.5-15)(18.5-12)(18.5-10)
= √18.5(3.5)(6.5)(8.5)
= √ 3,577.4375
A = 59.8116
which is approximately 59.8 square units

PLEASE HELP!! Due very soon!!! - The graph below represents the height of a football pass, in feet, x seconds after the ball is thrown. Which of the following best describes the interpretation of f(2)? (Attached are the multiple choice answers)
Answer:
The ball is 7 feet above the ground 2 seconds after it is thrown.
Step-by-step explanation:
As per the given statement, we are given a graph of function [tex]f(x)[/tex] where 'x' is time (in seconds) in the current scenario.
Time is plotted on x axis and height of football is plotted on y axis.
[tex]f(x)[/tex] is the height of football according to change in time.
Following are the few things that can be observed from the given curve:
1. Initial Height of football is ~4.8 feet i.e. at 0 seconds of time.
2. Football reaches a maximum height of ~7.2 feet at 1.5 seconds.
3. After 1.5 seconds, the height of football starts decreasing.
Here f(2) means, the height of ball at 2 seconds of time.
It is clearly visible from the given graph that height is 7 feet at 2 seconds.
Please refer to the attached answer image. Height at 2 seconds is marked as point P.
Hence, The ball is 7 feet above the ground 2 seconds after it is thrown.
