HELP ME! Look at the stem-and-leaf plot. What is the mode of the numbers?
Given:
The stem-and-leaf plot or a date set.
To find:
The mode of data set.
Solution:
From the given stem-and-leaf plot, we get the numbers of the data set.
64, 67, 70, 70, 71, 75, 76, 78, 78, 80, 82, 82, 88, 91, 93, 94, 97, 98, 100, 100, 100
Mode of a date set is the most frequent value.
In the given data set the most frequent value is 100 with frequency 3.
Therefore, the mode of data set is 100. Hence, option A is correct.

Can someone answer this please
Answer:
40
Step-by-step explanation:
The first step is to calculate x
because it's a straight line all angles must add up to 180
we can write the following equation
(3x+94)+(x+30)+(2x-4)=180
6x+120=180
6x=60
x=10
Now to solve for COD just plug in 10 for x+30
10+30=40
Kylee manages a small theme park and she has been analyzing the attendance data. Kylee finds that the number of visitors exponentially as the tempature increases, and this situation is represented by the function f(x) = 4 ^ x Kylee also finds a linear equation that no deals the number of people who leave the park early depending on the change in temperature , and it is represented by f(x) = - x + 5. The graph of the two functions is below. Find the solution to the two functions and explain what the solution represents.

Chuck has 20 feet of fencing and wishes to make a rectangular fence for his dog Rover. If he uses his house for one side of the fence what is maximum area?
Answer:
50 square feet.
Step-by-step explanation:
Let x represent the width of the fence and y represent the length of the fence.
One side of the length is already covered by the house. This leaves 2x and y. This must sum to 20. Hence:
[tex]2x+y=20[/tex]
The area of the enclosure will be given by:
[tex]A=xy[/tex]
From the first equation, we can subtract 2x from both sides:
[tex]y=20-2x[/tex]
Substitute:
[tex]A=x(20-2x)[/tex]
This is now a quadratic. Recall that the maximum value of a quadratic always occurs at its vertex. So, find the vertex of the equation. Distribute:
[tex]A=20x-2x^2[/tex]
In this case, a = -2, b = 20, and c = 0.
Hence, the vertex is:
[tex]\displaystyle x=-\frac{b}{2a}=-\frac{(20)}{2(-2)}=5[/tex]
Substitute this value back into the equation and evaluate:
[tex]A(5)=20(5)-2(5)^2=50\text{ ft}^2[/tex]
The maximum area is 50 square feet.
This occurs when the dimensions are 5 feet by 10 feet.
Without plotting these numbers, decide which inequalities are true. Check all that apply.

Suppose x and y are real numbers and x+y=2. Which of the following statements must be true about x and y? A. If one of the numbers is irrational then both are irrational. B. Both x and y must be rational. C. Both x and y must be irrational. D. One of the numbers can be irrational but not both.
Answer:
I think that it is A
The solution is : The correct option is,
(A) the sum of x and y is a rational number
What is number?A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.
here, we have.
We are given to consider that x = 1.5 and y = 3.
We are to select the statement that is true about the sum x + y.
To select the correct statement, we first find the value of the sum x + y.
We have
x+ y = 1.5 + 3 = 4.5
So, the value of the sum is 4.5. It is a real number.
We know that a real number is
(i) rational, if the digits after the decimal are either terminating or repeating,
(ii) irrational, if the digits after the decimal are neither repeating nor terminating.
The sum 4.5 has terminating digits after the decimal, so it is a rational number.
Thus, the sum of x and y is a rational number.
Option (A) is CORRECT.

Step-by-step explanation:
Given
[tex]\frac{3x}{x + 2} + \frac{4x}{x - 2} = \frac{ax^2 + bx}{x^2 + c}[/tex]
Required
Find a, b and c
[tex]\frac{3x}{x + 2} + \frac{4x}{x - 2} = \frac{ax^2 + bx}{x^2 + c}[/tex]
Take LCM
[tex]\frac{3x(x -2) + 4x(x+2)}{(x + 2)(x - 2)} = \frac{ax^2 + bx}{x^2 + c}[/tex]
Expand
[tex]\frac{3x^2 -6x + 4x^2+8x}{x^2 - 4} = \frac{ax^2 + bx}{x^2 + c}[/tex]
Collect like terms
[tex]\frac{3x^2 + 4x^2-6x+8x}{x^2 - 4} = \frac{ax^2 + bx}{x^2 + c}[/tex]
[tex]\frac{7x^2+2x}{x^2 - 4} = \frac{ax^2 + bx}{x^2 + c}[/tex]
By direct comparison:
[tex]ax^2= 7x^2 \to a = 7[/tex]
[tex]bx = 2x \to b = 2[/tex]

The probability distribution for a random variable x is given in the table

Probability- .17 .13 .33 .16 .11 .10
Find the probability that -2 < or equal to X < or equal to 2
Answer:
[tex]P(-2 \le x \le 2) =0.60[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{ccccccc}x & {-5} & {-3} & {-2} & {0} & {2} & {3} \ \\ P(x) & {0.17} & {0.13} & {0.33} & {0.16} & {0.11} & {0.10} \ \end{array}[/tex]
Required
[tex]P(-2 \le x \le 2)[/tex]
From the distribution, the above is equivalent to:
[tex]P(-2 \le x \le 2) =P(x = -2) +P(x = 0)+P(x = 2)[/tex]
We have:
[tex]P(x = -2) = 0.33[/tex]
[tex]P(x = 0)=0.16[/tex]
[tex]P(x = 2) = 0.11[/tex]
So:
[tex]P(-2 \le x \le 2) =P(x = -2) +P(x = 0)+P(x = 2)[/tex]
[tex]P(-2 \le x \le 2) = 0.33 + 0.16 +0.11[/tex]
[tex]P(-2 \le x \le 2) =0.60[/tex]

A boy pulls a wagon a distance of 1.2 km. An applied force of 22N is directed at an angle of 25 degrees above the horizontal. How much work is done?
Answer: 23.92 kJ
Step-by-step explanation:
Given
Distance moved by wagon is [tex]d=1.2\ km[/tex]
Force [tex]F=22\ N[/tex] directed at an angle of [tex]25^{\circ}[/tex] above the horizontal
Only the horizontal component of the force that is, [tex]22\cos 25^{\circ}[/tex]the wagon will cause the wagon to move, while the other force is perpendicular to the wagon and thus produce zero displacements.
Work done is
[tex]W=F\cdot s\\W=22\times 1.2\times 10^3\times \cos 25\\W=23.92\ kJ[/tex]
thus, 23.92 kJ of work is done on the wagon.
I NEED HELP ON THIS PROBLEM PLS
Answer:
only A
Step-by-step explanation:
A is correct because if a number is less than 7, the number under the square root will be negative, and that will yield an imaginary (or non-real number)
B is incorrect because even if you choose a number less than 7, the result will still yield a real number
C is incorrect due to the same logic as B
D is incorrect because you can take the cube root of a negative number without it being non-real.

The terminal ray of an angle passes through the point (16,–12). What is the value of sine for this angle?
Answer:
-3/5
Step-by-step explanation:
Given :-
The terminal ray of an angle passes through the point (16,–12).And we need to find the value of sine for this angle. Therefore we can say that , Base = 16 units and Perpendicular = 12 units . So Using Pyhthagoras Theorem , we can find hypontenuse.
Using Pythagoras Theorem :-
[tex]:\implies[/tex] h² = p² + b²
[tex]:\implies[/tex] h² = 16² + 12²
[tex]:\implies[/tex] h² = 256 + 144
[tex]:\implies[/tex] h² = 400
[tex]:\implies[/tex] h = 20 u
Therefore the sine will be :-
[tex]:\implies[/tex] sinθ = p/h
[tex]:\implies[/tex] sinθ = 12/20
[tex]:\implies[/tex] sinθ = 3/5
And it is in third quadrant so , sine will be negative .[tex]:\implies[/tex] sinθ = -3/5
Therefore the value of sine is -3/5.

Q7. What is the equation of the system of equations below? Explain how
you arrived at your answer
W
18x + 15-y-0
5y - 90x + 12
Answer: 18x -15 -y =0
Step-by-step explanation:
because linear equations in two variables are always in the format of ax+by+c=0
where a,b and c are constant terms
in this case a = 18; ax= 18x
b= -1 , by= -y
c= 15
Answer:
90x + 75 = 90x + 12, they don't intersect
Step-by-step explanation:
18x + 15 - y = 0
5y = 90x + 12
1. We will be using substitution, to do so, bring y to the other side in the first eqaution.
18x + 15 - y = 0
18x + 15 = y
2. Now plug in 18x+15 into the second equation
5(18x + 15) = 90x + 12
3. Distribute and solve for x
90x + 75 = 90x + 12
Because the slopes are the same (90x) this means that the system does not have an intersect.

Answer: [tex]m=\frac{-30}{79},\ y=5.40[/tex]
Step-by-step explanation:
Given
Points are [tex]\left(6\frac{1}{3},3\right),\ \left(19\frac{1}{2},-2\right)[/tex]
Convert mixed numeral to fraction
[tex]\left(6\frac{1}{3},3\right)\Rightarrow \left(\dfrac{19}{3},3\right)\\\\\left(19\frac{1}{2},-2\right)\Rightarrow \left(\dfrac{39}{2},-2\right)[/tex]
Slope of the line is
[tex]\Rightarrow m=\dfrac{3-(-2)}{\dfrac{19}{3}-\dfrac{39}{2}}\\\\\Rightarrow m=\dfrac{5}{\dfrac{38-117}{6}}\\\\\Rightarrow m=\dfrac{-30}{79}[/tex]
Equation of line
[tex]\Rightarrow \dfrac{y-3}{x-\dfrac{19}{3}}=\dfrac{-30}{79}\\\\\text{for y-intercept, put x=0}\\\\\Rightarrow \dfrac{y-3}{0-\dfrac{19}{3}}=\dfrac{-30}{79}\\\\\Rightarrow y-3=\dfrac{190}{79}\\\\\Rightarrow y=3+2.40\\\Rightarrow y=5.40[/tex]
