what is the mode for the data set 49,47,46,40,48,41,44,49,45,42,43
Mode: the number that occurs the most in a set of data.
Although it's optional, I always like to order the numbers from least to greatest so it makes it easier to see what number repeats more than anything else.
Least to greatest - 40,41,42,43,44,45,46,47,48,49,49
The mode for this set of data is 49. The mode is 49 because 49 is the only number that occurs more than once. No other numbers in this set of data appear twice except 41.

Consider the expression 6r – r + 8(15 – r) + 23 – 6 .
Part A Is –3r + 137 equivalent to the given expression? Write your answer in the space provided .
6r -4 +8(15-r) + 23
expand brackets
6r -4 +120 -8r + 23
collect like terms
120 + 23 - 4 = 139
6r - 8r = -2r
139 - 2r
139 - 2r = -3r + 137
-137 from both sides
-2r = -3r -2
add 3r
R = -2
sub in both equations and see if you get the same value
-3r + 137
-3 (-2) + 137
6 +137 = 143
139 - 2r
139 - 2(-2)
139 + 4
143
yes they are equal
Final answer:
After simplifying the given expression by combining like terms and using the distributive property, we find that the simplified form is indeed -3r + 137, which means it is equivalent to the original expression.
Explanation:
To determine if the expression -3r + 137 is equivalent to the given expression 6r – r + 8(15 – r) + 23 – 6, we need to simplify the given expression.
Let's simplify the given expression step-by-step:
Combine like terms: 6r - r = 5r.Distribute the 8 within the parentheses: 8(15) - 8(r) = 120 - 8r.Combine the constants: 23 - 6 = 17.Add the constant from step 3 to the constant from step 2: 120 + 17 = 137.Combine the results from steps 1 and 2: 5r - 8r = -3r.Add the results from steps 4 and 5 to get the simplified expression: -3r + 137.Therefore, the simplified form of the given expression is indeed -3r + 137, which means it is equivalent to the given expression.

Can someone please tell me if my answers are correct??
Answer:
I think they are all correct but 2 and 4 might be wrong. (I don't see the shapes very well.)
I can't see that well but on #2, can't you half it? If you can, it has 1 line of Symmetry. If you can't, it has no lines of symmetry
On #4, you might be able to half it from the lower left corner and the upper right corner. If it works, there is 1 line of symmetry, if it doesn't it has none
choose the system of inequalities that best matches the graph below.
a) y<2x+2, y<x
b) y<2x, y<_x
c) y<_x-2, y>-x
D) y<2x+2, y> -x
Answer:
D) [tex]y\:<\:2x+2[/tex], [tex]y\:>\:-x[/tex]
Step-by-step explanation:
The blue boundary line has a y-intercept of 2 and a slope of 2.
It has equation : [tex]y=2x+2[/tex]
Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is
[tex]y\:<\:2x+2[/tex]
The blue boundary line passes through the origin and has slope [tex]-1[/tex].
Its equation is [tex]y=-x.[/tex]
Since the boundary line is not solid and the right half-plane is shaded, its inequality is [tex]y\:>\:-x[/tex]
The correct choice is D.
The correct choice is D: y < 2x + 2, y > -x.
The blue boundary line is represented by the equation y = 2x + 2.
Since the lower half-plane is shaded, the inequality is y < 2x + 2.
The blue boundary line also passes through the origin and has a slope of -1, which gives it the equation y = -x.
Since the right half-plane is shaded, the inequality is y > -x.
So, the correct choice is D: y < 2x + 2, y > -x.

There are 29 pencils in a basket. 7 of these pencils are green. The rest of them are yellow.
(A) what is the ratio of yellow pencinls to green pencils?
(b) what is the ratio of all pencils in the basket to yellow pencils
[tex]\huge\boxed{22:7}\ \huge\boxed{29:22}[/tex]

a fair die is cast four times. Calculate the probability of obtaining exactly two 6's
Answer:
25/216 or 0.1157
Step-by-step explanation:
The probability of getting a 6 is 1/6.
The probability of not getting a 6 is 5/6
We roll a die 4 times and want 2 sixes, and 2 not sixes.
We want a combination of 2 sixes from 4 rolls, so we can use the binomial formula to solve this...
(4C2)(1/6)²(5/6)² = 6(1/36)(25/36) = (1/6)(25/36) = 25/216 = 0.1157
The long hand way of solving this is to list the 6 ways we can roll our desired result along with their probabilities...
We could get
6, 6, not 6, not 6 (1/6)(1/6)(5/6)(5/6) = 25/1296
6, not 6, 6, not 6 (1/6)(5/6)(1/6)(5/6) = 25/1296
6, not 6, not 6, 6 (1/6)(5/6)(5/6)(1/6) = 25/1296
not 6, not 6, 6, 6 (5/6)(5/6)(1/6)(1/6) = 25/1296
not 6, 6, not 6, 6 (5/6)(1/6)(5/6)(1/6) = 25/1296
not 6, 6, 6 not 6 (5/6)(1/6)(1/6)(5/6) = 25/1296
There are 6 different way this can happen, each having a probability of 25/196. We add up the probabilities, getting 150/1296, which reduces to
25/216

Step-by-step explanation:
Consider the expression below. Place the steps required to determine the sum of the two expressions in the correct order. 3x+6/x^2-x-6 + 2x/x^2+x-12
Answer:
1) Factor the denominator and the numerator of each fraction.
2) Simplify.
3) Find the Least common denominator (LCD).
4) Rewrite the LCD. Divide it by the denominator of the first fraction and multiply the result of the division by its numerator (The LCD is the same denominator of the second fraction, so its numerator stays the same).
5) Apply Distributive property on the numerator and on the denominator.
6) Add like terms.
Step-by-step explanation:
The steps required to determine the sum of the two expressions are:
1) Factor the denominator and the numerator of each fraction:
[tex]\frac{3x+6}{x^2-x-6}+\frac{2x}{x^2+x-12}=\frac{3(x+2)}{(x-3)(x+2)}+\frac{2x}{(x-3)(x+4)}[/tex]
2) Simplify (Remember that [tex]\frac{(x+2)}{(x+2)}=1[/tex]):
[tex]\frac{3}{(x-3)}+\frac{2x}{(x-3)(x+4)}[/tex]
3) Find the Least common denominator (LCD). In this case this is:
[tex]LCD=(x-3)(x+4)[/tex]
4) Rewrite the LCD. Divide it by the denominator of the first fraction and multiply the result of the division by its numerator. As the LCD is the same denominator of the second fraction, its numerator stays the same:
[tex]=\frac{3(x+4)+2x}{(x-3)(x+4)}[/tex]
5) Apply Distributive property on the numerator and on the denominator:
[tex]=\frac{3x+12+2x}{x^2+x-12}[/tex]

Answer:
x = 1.56 or x = -2.56
Step-by-step explanation:
From the equation;
x2 +x − 4 = 0
a = 1 , b = 1, and c = -4
x = (-b ± √(b² -4ac))/2a
= (-1 ± √(1²- 4×1×-4))/2
= ( -1 ± √(17)/2
= (-1 ± 4.12)/2
= (-1 + 4.12)/2 or (-1 - 4.12)/2
x = 1.56 or x = -2.56

rewrite the function f(x)=x^2-6x-60 by completing the square
To rewrite f(x) = x^2 - 6x - 60 by completing the square, you add and subtract (6/2)^2 within the equation and refactor to get f(x) = (x - 3)^2 - 69, with the vertex at (3, -69).
To rewrite the function f(x) = x^2 - 6x - 60 by completing the square, follow these steps:
Write the equation in the form x^2 - bx = c.Find (b/2)^2, which is the number to be added to both sides to complete the square. For our equation, (6/2)^2 = 9.Add and subtract this number inside the equation. So you have: f(x) = x^2 - 6x + 9 - 9 - 60.Rewrite the quadratic part as a binomial square: f(x) = (x - 3)^2 - 69.The function is now in the completed square form. The vertex of this parabola is at (3, -69).

A triangle has side lengths measuring 2x + 2 ft, x + 3 ft, and n ft. Which expression represents the possible values of n, in feet? Express your answer in simplest terms. x – 1 < n < 3x + 5 n = 3x + 5 n = x – 1 3x + 5 < n < x – 1
Answer:
[tex]x-1<n<3x+5.[/tex]
Step-by-step explanation:
If a, b and c are the lengths of the triangle's sides, then
[tex]a+b>c,\\ \\a+c>b,\\ \\b+c>a.[/tex]
Since
[tex]a=2x+2,\\ \\b=x+3,\\ \\z=n,[/tex]
then
[tex]2x+2+x+3>n\Rightarrow n<3x+5,\\ \\2x+2+n>x+3\Rightarrow n>1-x,\\ \\x+3+n>2x+2\Rightarrow n>x-1.[/tex]
Thus,
[tex]x-1<n<3x+5.[/tex]
Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side. The correct option is A, 3x + 5 > n > x - 1.
What is triangle inequality theorem?Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,
(a+b) > c
(b+c) > a
(c+a) > b
Given the three sides of the triangle 2x + 2 ft, x + 3 ft, and n ft. Now using the triangle inequality theorem we can write,
2x + 2 + x + 3 > n → 3x + 5 > n
2x + 2 + n > x + 3 → n > -x + 1
x + 3 + n > 2x + 2 → n > x - 1
Since x can not be a negative term therefore, we can write,
3x + 5 > n > x - 1
Hence, the correct option is A, 3x + 5 > n > x - 1.
