The spinner below shows 5 equally sized slices. Kala spun the dial 500 times and got the following results. Fill in the table below. Round your answers to the nearest thousandth.
Answer:
0.382
0.4
option (a)
Step-by-step explanation:
Formula to calculate probability
a)
probability = number of times event occur / total number of trials
Experimental probability of landing on white = 191/500 = 0.382
b)
probability = favourable outcome / total outcome
Theoretical probability of landing on white = 2/5 = 0.4
c)
As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.
The student must calculate frequencies, relative frequencies, and probabilities based on the results from spinning a dial. The frequencies are the counts of outcomes, relative frequencies are these counts divided by total spins, and probabilities are based on the assumption of a fair spinner.
Explanation:The question is about filling in a table with the results from spinning a dial 500 times. This tasks involves calculating frequencies, relative frequencies, and probabilities which are fundamental concepts in probability and statistics. Since we do not have the actual results, I will explain the process of completing the table:
Determine the frequency of each outcome by counting the number of times it occurred in the 500 spins.To find the relative frequency, divide the frequency of each outcome by the total number of spins (500 in this case).Round the relative frequencies to the nearest thousandth as directed.The probability of each outcome, assuming the spinner is fair, would be 1 divided by the number of slices (1/5 for a spinner with 5 slices).Example Calculation for Frequency:If an outcome occurred 100 times in 500 spins, the frequency is 100. To calculate the relative frequency, divide 100 by 500, which equals 0.2. Round this to the nearest thousandth to get 0.200.
Remember to round all your final calculated values appropriately as per the instructions given in the question.

Find the value of x in the triangle shown below.
x =
In the triangle it has 74, 20, and x degrees
Answer:
86
Step-by-step explanation:
Angles in a triangle add up to 180 degrees
add 74 with 20 to get 94
subtract 94 from 180 to get the value of x
180-94=86
The value of x in the triangle whose two interior angle values are given as 74 degrees and 20 degrees is 86 degrees.
What is a triangle?A triangle is a closed 2-dimensional polygon with three angles and three straight sides.
According to the Triangle Angle Sum Theorem, the sum of the three interior angles in a triangle is always 180°.
Hence,
angleA + angleB + angleC = 180°
Given the data in the question;
First angle in the triangle A = 74°Second angle in the triangle B = 20°Third angle in the triangle C = xWe substitute our given values into the expression above.
angleA + angleB + angleC = 180°
74° + 20° + x = 180°
94° + x = 180°
x = 180° - 94°
x = 86°
Hence, the value of x in the triangle whose two interior angle values are given as 74 degrees and 20 degrees is 86 degrees.

Answer:
a = 20; b = 2√101
Step-by-step explanation:
The triangle at upper left and the one at lower right are similar. Ratios of corresponding sides are equal, so ...
200/a = a/2
400 = a^2
√400 = 20 = a
Then, by the Pythagorean theorem, the value of b can be found:
b = √(a^2 + 2^2) = √(400 +4) = √4·√101
b = 2√101

Given that lines b and c are parallel, select all that apply. Which pairs of angles are supplementary?
1 and 4
5 and 6
2 and 8
3 and 6
Supplementary angles, totaling 180 degrees, are demonstrated by ∠2 and ∠4, as well as ∠3 and ∠5, in the context of lines b and c, as depicted in the diagram.
Supplementary angles are pairs of angles whose measures add up to 180 degrees. In the context of lines b and c, the identified supplementary angle pairs are ∠2 and ∠4, as well as ∠3 and ∠5. These pairs satisfy the condition that the sum of their measures equals 180 degrees. Visually, this relationship is evident in the provided diagram, reinforcing the concept of supplementary angles. Specifically, the equation ∠2 + ∠4 = 180° and ∠3 + ∠5 = 180° illustrates the supplementary nature of these angle pairs. Understanding supplementary angles is crucial in geometry, as it provides a fundamental principle for evaluating the relationships between angles formed by intersecting lines. In the given scenario, the angles ∠2, ∠4, ∠3, and ∠5 exhibit supplementary properties, emphasizing their collective role in forming a straight line and contributing to the overall understanding of geometric configurations.

Ms.Call is renting a truck for a day. The two choices she has are Company A and Company B.
Company A charges $35 per day plus $0.45 per mile
Company B charges $60 per day plus $0.25 per mile.
What is the minimum number of miles that Ms.Call would need to drive in order to make renting from Company B a better deal.
Answer:
125 miles
Step-by-step explanation:
Write formulas for the amount of $ that would be due each of the two companies and set these equal to one another prior to solving for the number of days:
A: $35 + ($0.45/mile)x
B: $60 + ($0.25/mile)x
Then $35 + ($0.45/mile)x = $60 + ($0.25/mile)x, or
($0.20/mile)x = $25
$25
dividing both sides by $0.20 yields x = ------------------- = 125 miles
$0.20/mile
The charges made by the two companies would become equal after the 125th mile. After that, Company B would become cheaper.
Ms. Call would need to drive at least 125 miles for the rental from Company B to be more cost-effective.
Explanation:To find out when Company B becomes a better deal, we need to set up an equality and solve it for the number of miles. We can create the equation as follows:
Company A cost = Company B cost.
So, $35 + $0.45x = $60 + $0.25x.
Here x represents the number of miles driven. If we simplify this equation, we have:
$0.20x = $25.
Thus, solving for x: x = 25/0.20 = 125
So, Ms. Call would need to drive at least 125 miles in order for Company B to be a better deal.

Write an equation for that graph,where y depends on x.
____
To create an equation for a graph where y depends on x, identify the type of relationship presented by the graph. For a linear relationship, use the formula y = mx + b, where 'm' is the slope and 'b' is the y-intercept. Determine the slope using two points on the line and then solve for 'b' using the slope and one of the points.
Explanation:Creating an equation for a graph where y depends on x is a common task in algebra. It's essential to identify the type of relation presented by the graph, which may include linear, quadratic, exponential, or logarithmic relationships. Let's assume, for example, that the graph represents a simple linear relationship.
In this case, you would use the formula for a line, which is y = mx + b. 'm' represents the slope of the line, and 'b' stands for the y-intercept.
To find the slope 'm', you can choose two points on the line and calculate the change in y divided by the change in x. Once the slope is determined, plug one of the points' coordinates into the equation and solve for 'b', the y-intercept. This will give you the equation for the line.

The equation for that graph, where y depends on x can be expressed in slope-intercept form as: y = -2x + 6.
What is the equation of a linear graph?To find the equation of the line, you can use the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. First, find the slope (m) using any two given points on the graph, i.e. (0, 6) and (4, -2):
[tex]\[ m = \frac{{\text{{change in }} y}}{{\text{{change in }} x}} = \frac{{-2 - 6}}{{4 - 0}} = \frac{{-8}}{{4}} = -2 \][/tex]
Now, substitute one of the points (e.g., (0, 6)) and the slope into the equation:
y = mx + b
6 = -2(0) + b
b = 6
So, the equation of the line is y = -2x + 6.

Step-by-step explanation:
If the graph of the function [tex]y=kf(x) +d[/tex] represents the transformations made to the graph of [tex]y= f(x)[/tex] then, by definition:
If [tex]0 <k <1[/tex] then the graph is compressed vertically by a factor k.
If [tex]|k| > 1[/tex] then the graph is stretched vertically by a factor k
If [tex]k <0[/tex] then the graph is reflected on the x axis.
If [tex]d> 0[/tex] the graph moves vertically upwards d units.
If [tex]d <0[/tex] the graph moves vertically down d units.
In this problem we have the function [tex]y = cosx[/tex]
And we know that The graph of [tex]y = cosx[/tex] is transformed with a vertical compression by a factor of 1/2 and a translation 3 units up
therefore it is true that [tex]0 <k <1[/tex] and [tex]k=\frac{1}{2}[/tex] and [tex]d =3> 0[/tex]
