Answers
The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.
The correct answer is 4.
To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.
Given information:
- Circle C (cats): 15
- Circle D (dogs): 21
- Circle F (fish): 12
- Overlap of C and F: 2
- Overlap of F and D: 0
- Overlap of D and C: 3
- Overlap of all 3 circles: 1
- Number outside of circles: 14
To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.
From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.
To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.
Therefore, from the options given correct one is 4.

Translate to a system of equations and solve:Whitney has a collection of nickels and dimes, with a total value of $5.40. The number of nickels is two less than four times the number of dimes. How many nickels and how many dimes does she have?
Answers
Let n and d be the number of nickels and dimes, respectively. Since the total values is $5.40, we can write
\(0.05n+0.10d=5.40\)On the other hand, since the number of nickels is two less than four times the number of dimes, we have
\(n=4d-2\)Then, we have the following system of equations:
\(\begin{gathered} 0.05n+0.10d=5.40\ldots(a) \\ n=4d-2\ldots(b) \end{gathered}\)Solving by substitution method.
By substituting equation (b) into (a), we have
\(0.05(4d-2)+0.10d=5.40\)By distributing 0.05 into the parenthesis, we have
\(0.2d-0.1+0.10d=5.40\)and by combining similar terms, we have
\(0.3d-0.1=5.40\)then, we have
\(\begin{gathered} 0.3d=5.40-0.1 \\ 0.3d=5.30 \end{gathered}\)By dividing both sides by 0.3, we get
\(\begin{gathered} d=\frac{5.30}{0.3} \\ d=17.666 \end{gathered}\)D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. What is mZDEF?

Basis step: Let \(n=2\). Then

so \(2! < 2^2\).
Inductive step: Assume \(k! < k^k\). We want to show that \((k+1)! < (k+1)^{k+1}\).
Now
\((k+1)! = (k+1) \cdot k! \\\\ ~~~~~~~~~~~ < (k+1) \cdot k^k \\\\ ~~~~~~~~~~~ < (k+1) \cdot k^{k+1} \\\\ ~~~~~~~~~~~ < (k+1) \cdot (k+1)^{k+1}\)
where the first inequality follows from the induction hypothesis; the second follows from multiplying the right side by some \(k>2\); and the third from adding the remaining terms to complete the binomial expansion \((k+1)^{k+1}\), all of which are positive since they are some power of \(k>2\).

Given (21,7) and (x,
1), find all x such that the distance between these two points is 17.
Answers
Answer:
21+/-sqrt(253)=x
So one value for x is 21+sqrt(253)
and another is 21-sqrt(253)
Problem:
Given (21,7) and (x,1), find all x such that the distance between these two points is 17.
Step-by-step explanation:
Change in x is x-21
Change in y is 7-1=6
distance^2=(change in x)^2+(change in y)^2
17^2=(x-21)^2+(6)^2
289=(x-21)^2+36
Subtract 36 on both sides:
289-36=(x-21)^2
253=(x-21)^2
Take square root of both sides:
+/-sqrt(253)=x-21
Add 21 on both sides:
21+/-sqrt(253)=x
There are two values of "x" that satisfy the given condition:
\(1. \( x = 21 + \sqrt{253} \) \ 2. \( x = 21 - \sqrt{253} \)\) These are the values of "x" such that the distance between the points (21, 7) and (x, 1) is 17.
Given two points (21, 7) and (x, 1) and the distance formula:
\(Distance = \sqrt{{(x_2 - x_1)^2 + (y_2 - y_1)^2}}\)
We want to find all the values of "x" such that the distance between these two points is 17:\(\[ 17 = \sqrt{{(x - 21)^2 + (1 - 7)^2}} \]\)
Simplifying the equation: \(\[ 289 = (x - 21)^2 + 36 \]\)
Moving the constant term to the other side:\(\[ (x - 21)^2 = 253 \]\)
Taking the square root of both sides: \(\[ x - 21 = \pm \sqrt{253} \]\)
Finally, isolating \("x": \[ x = 21 \pm \sqrt{253} \]\)
So, there are two values of "x" that satisfy the given condition:
\(1. \( x = 21 + \sqrt{253} \) \ 2. \( x = 21 - \sqrt{253} \)\)
These are the values of "x" such that the distance between the points (21, 7) and (x, 1) is 17.

7.86, 7.87, 7.99, 8.03
The median of the lower half is:

which grows at the fastest rate for increasing values of x
\(f(x)=4*2^x\\h(x)=9x^2+25\\\\g(x)=15x+6\)
Answers
The function that grows at the fastest rate for increasing values of x is f(x) = 4×2ˣ.
We can see this by comparing the growth rates of the three functions for larger and larger values of x.
As x gets larger, the exponential function f(x) grows much faster than the other two functions, which are both polynomial functions.
if we plug in x = 10, we get:
f(10) = 4×2¹⁰ = 4×1024 = 4096
h(10) = 9×10² + 25 = 925
g(10) = 15×10 + 6 = 156
As we can see, f(10) is much larger than h(10) and g(10), indicating that f(x) grows at a much faster rate than the other two functions.

hay 1230 personas, entre hombres y mujeres. Si se sabe que el número de mujeres, supera en 150 al número de hombres. ¿Cuántos hombres están habitando la mini ciudad?
Answers
There are 540 men living in the mini city.
x + (x + 150) = 1230
Simplifying this equation, we get:
2x + 150 = 1230
Subtracting 150 from both sides, we get:
2x = 1080
Dividing both sides by 2, we get:
x = 540
Therefore, there are 540 men living in the mini city.
To check our answer, we can substitute x = 540 into our original equation:
540 + (540 + 150) = 1230
690 = 1230
This is false, so there must be an error in our calculation. We can double-check our work by trying a different approach.
We know that the number of women exceeds the number of men by 150, so we can represent the number of women as (x + 150). We also know that the total number of people is 1230, so we can set up an equation:
x + (x + 150) = 1230
Simplifying this equation, we get:
2x + 150 = 1230
Subtracting 150 from both sides, we get:
2x = 1080
Dividing both sides by 2, we get:
x = 540

The length of BD is √40.
The slope of BD is 1/3
The slope of AB is 1/3.
Answers
Answer:
Option (2)
Step-by-step explanation:
ABCD is a parallelogram having vertices A(0,7) and C(2, 1).
Therefore, length of diagonal AC = \(\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
= \(\sqrt{(0-2)^2+(7-1)^2}\)
= \(\sqrt{40}\)
Since, diagonals of a rectangle measure the same and bisect each other,
Length of other diagonal BD will also measure \(\sqrt{40}\).

A bag contains 4 white,5 blacks and 2 blue balls. 3 balls are drawn one after the other without replacement from the bag .what is the probability that they are of different color
Answers
Answer:
24/99
Step-by-step explanation:
From the question given above, the following data were obtained:
White (W) balls = 4
Black (B) balls = 5
Blue (Bl) balls = 2
Probability that they are of different color =?
Next, we shall determine the total number of balls in the bag. This can be obtained as follow:
White (W) balls = 4
Black (B) balls = 5
Blue (Bl) balls = 2
TOTAL = 4 + 5 + 2 = 11 balls
Next, we shall determine the possible outcome of draw. This can be obtained as follow.
The possible outcome could be:
WBLB or WBBL or BBLW or BWBL or BLBW or BLWB
Next we shall determine the probability of each of outcomes.
Since the ball is drawn without replacement, it means the total number of ball will reduce after each draw.
White (W) balls = 4
Black (B) balls = 5
Blue (Bl) balls = 2
TOTAL = 11
P(WBLB) = 4/11 × 2/10 × 5/9 = 40/990
P(WBLB) = 4/99
P(WBBL) = 4/11 × 5/10 × 2/9 = 40/990
P(WBBL) = 4/99
P(BBLW) = 5/11 × 2/10 × 4/9 = 40/990
P(BBLW) = 4/99
P(BWBL) = 5/11 × 4/10 × 2/9 = 40/990
P(BWBL) = 4/99
P(BLBW) = 2/11 × 5/10 × 4/9 = 40/990
P(BLBW) = 4/99
P(BLWB) = 2/11 × 4/10 × 5/9 = 40/990
P(BLWB) = 4/99
Finally, we shall determine the probability that they are of different color. This can be obtained as follow:
P(WBLB) = 4/99
P(WBBL) = 4/99
P(BBLW) = 4/99
P(BWBL) = 4/99
P(BLBW) = 4/99
P(BLWB) = 4/99
Probability that they are of different color =?
Probability that they are of different color = P(WBLB) + P(WBBL) + P(BBLW) + P(BWBL) + P(BLBW) + P(BLWB)
= 4/99 + 4/99 + 4/99 + 4/99 + 4/99 + 4/99
= (4 + 4 + 4 + 4 + 4 + 4)/99
= 24/99
Thus, the probability that they are of different color is 24/99
