The mean of the following data values is 32. 19, 23, 35, 41, 42A. True B. False
Remember that mean of a set is another name for the average of that set. To find the mean of a data set, add all the values together and divide by the number of values in the set.
Thus, if we have the following set of values: 19, 23, 35, 41, 42, the mean would be:
[tex]\frac{19\text{ + 23 + 35 + 41 + 42}}{5}=\frac{160}{5}=32[/tex]The correct answer:

A spinner with 5 equally sized slices has 2 yellow slices, 2 red slices, and 1 blue slice. Yolanda spun the dial 40 times and got the following results. Answer the following. Round your answer to the nearest thousandth
Given: A spinner with 5 equally sized slices has 2 yellow slices, 2 red slices, and 1 blue slice.
Yolanda spun the dial 40 times and got Yellow 13 times, Red 13 times and Blue 14 times.
Required:
(a) Experimental probability of landing on Blue or Red
(b) Theoretical probability of landing on Blue or Red
(c) What happens when number of spins increases.
Explanation:
(a) Experimental probability =
[tex]Experimental\text{ Probability = }\frac{Number\text{ of trials in which the event occurs}}{total\text{ number of trials}}[/tex]Here, the event is landing on blue or red.
Number of trials in which Blue or Red occurs is 14+13=27
Total number of trials is 40.
So experimental probability is
[tex]\frac{27}{40}=0.675[/tex]Hence, experimental probability is 0.675.
(b) Theoretical probability is
[tex]Theoretical\text{ Probability = }\frac{Favorable\text{ Outcome}}{total\text{ outcome}}[/tex]Here, favorable outcomes for red and blue = 2+1 = 3.
And total possible outcomes = 5
So theoretical probability is
[tex]\frac{3}{5}=0.6[/tex]Hence, theoretical probability is 0.6.
(c) Now, as the number of spins will increase, number of trials will increase and experimental probability will become more and more precise. Hence, it will come closer to theoretical property. So both probabilities will become closer and closer though they might not be equal.
Final Answer:
(a) 0.675
(b) 0.600
(c) Option 1

if Samantha has 37 green apples and give 4 to her sister and 3 to her bestfriend. How many apples does Samantha have left?
The number of apples that has been left with Samantha is 30 apples which is calculated using subtraction.
Total number of apples that Samantha has = 37 apples
Apples that she gave to her sister = 4 apples
Apples that she gave to her bestfriend = 3 apples
Total apples that she gave will be calculated by using addition.
Total apples that she gave = 4 + 3 = 7 apples
Now, the apples left with her will be calculated using subtraction.
Apples left with her = 37 - 7 = 30 apples.
Therefore, we get that, the number of apples that has been left with Samantha is 30 apples which is calculated using subtraction.

which of the binomials below is a factor of this trinomial? x^2+14x+40A. x-9B. x+10C. x+14D. x^2 + 40
Given the following trinomial expression:
[tex]x^2+14x+40[/tex]To factor the trinomial, we need two numbers:
The product of them = 40
The sum of them = 14
The factors of 40 will be as follows:
40 = 1 x 40 ⇒ sum = 41
40 = 2 x 20 ⇒ sum = 22
40 = 4 x 10 ⇒ sum = 14
40 = 5 x 8 ⇒ sum = 13
so, the numbers will be 4 and 10
The factoring of the expression will be as follows:
[tex]x^2+14x+40=(x+4)(x+10)[/tex]So, the answer will be B. x+10
C. Two angles are supplementary. One angle measures 2° less than 3 times the other. What are the measures of the two angles?
C.
if x one of the angles, then, the other angle is 3x - 2. Due to these angles are supplementary, you can write:
x + 3x - 2 = 180
by solving for x you obtain:
x + 3x - 2 = 180 simplify like terms left side
4x - 2 = 180 add 2 both sides and divide by 4 both sides
4x = 180 - 2
4x = 178
x = 178/4
x = 44.5
the other angle is then:
3x - 2 = 3(44.5) - 2 = 131.5
Hence, the two angles are 44.5° and 131.5°

A. What is the area, in square meters, of 6 triangles? If you get stuck, draw a diagram.
The area of the 6 required triangles is 1/3m².
What are triangles?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane. The seven different kinds of triangles that can be found in nature—equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene—must be studied and built.So, one square meter is equal to one huge square.
The larger square has now been divided into nine smaller squares.9 tiny square meters of space equals 1 square meter of space.So, using the unitary method, we can discover a single little square.1 tiny square is equal to 1/9 square meter.Each little square now has two similar triangles on each side of it.Now,
One triangle's surface area equals half that of a small square, or (1/2) (1/9) = 1/18 square meters.Using the unitary approach once more, determine the area of 6 triangles.The area of 6 triangles is equal to the 6 * area of 1 triangle, which is:6 * (1/18) = 1/3 square meter.Therefore, the area of the 6 required triangles is 1/3m².

Based on the question, the vertical asymptote is x = -4 and x = 3. This means the denominator cannot have these x-values or else, the function becomes undefined. Hence, from these x-values, we can say that the factors of the denominator are:
[tex](x+4)(x-3)[/tex]Multiplying the factors, we get:
[tex]\begin{gathered} \Rightarrow x^2-3x+4x-12 \\ \Rightarrow x^2+x-12 \end{gathered}[/tex]So, the denominator of our rational function must be x² + x - 12 in order to have those vertical asymptotes.
Another given information is that our x-intercepts are at x = -2 and x = 5. This means that the numerator must be zero at these x-values. Hence, we can say that some factors of the numerator are:
[tex](x+2)(x-5)[/tex]Multiplying these two factors, we get:
[tex]\begin{gathered} \Rightarrow x^2-5x+2x-10 \\ \Rightarrow x^2-3x-10 \end{gathered}[/tex]This means x² - 3x - 10 should be part of our numerator.
Another given information is that the horizontal asymptote is at y = 4. This means that the ratio between the leading coefficients of the numerator and denominator is 4. (since both have the same degree)
So, in order to have a ratio of 4, we will multiply our numerator by 4.
[tex]4(x^2-3x-10)\Rightarrow4x^2-12x-40[/tex]Therefore, our numerator must be 4x² - 12x - 40. And as mentioned above, the denominator must be x² + x - 12. So, the rational function is:
[tex]y=\frac{4x^2-12x-40}{x^2+x-12}[/tex]
