A spinner is divided into three equal parts A, B, and C. The repeated experiment of spinning the spinner twice is simulated 125 times. A table of outcomes is shown.
The probability you expect the spinner to not land on B is 0.4.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, a spinner is divided into three equal parts A, B, and C.
The repeated experiment of spinning the spinner twice is simulated 125 times.
The total number of outcomes = 125
The number of favorable outcomes = 12+18+15+17+13= 75
Probability of landing on B = 75/125
= 0.6
Probability of not landing on B
= 1-0.6
= 0.4
Therefore, the probability you expect the spinner to not land on B is 0.4.

y-intercept: 5
slope: -1
equation: y = -x + 5
Step-by-step explanation:
The y-intercept is when x is 0, and it is shown on the table as 5.
The slope can be found by doing [tex]y_1-y_2/x_1-x_2[/tex], which is 6-5/-1-0 = 1/-1 = -1.
The equation is y = mx + b, so we can write it as y = -x + 5

Write the standard form of the quadratic function that has the indicated vertex and whose graph passes through the given point. Use a graphing utility to verify your result.
Vertex:
(−4, −1);
Point:
(−2, 4)
The standard form of the quadratic function that has the indicated vertex and whose graph passes through the given point is 1/36(x +4)² - 1.
What is Quadratic function?Equation of a quadratic function in the vertex form is given by;
f(x) = a(x - h)² + k
Here, (h, k) is the vertex of the parabola representing the quadratic function;
Given;
Vertex of the quadratic function (−4, −1);
Parabola passes through a point (−2, 4);
Substitute the vertex in the quadratic function;
f(x) = a(x +4)² - 1
Because, this parabola passes through a point (7, 0),
0 = a(-2- 4)² - 1
0 = 36a - 1
a = 1/36

In the interval 0° ≤ x ≤360°, find the values of x for which tan x =0. 8645 Give your answers to the nearest degree
The inverse tangent function [tex]tan^{-1}[/tex] can be used to find the values of x for which tan x = 0.8645 in the interval 0 degrees < x < 360 degrees. The inverse tangent function gives us the angle that has a tangent equal to the input value.
The function can be expressed as:
[tex]x = tan^{-1 (0.8645)}[/tex]
Using a scientific calculator or trigonometry tables, we can find that the value of [tex]tan^{-1 (0.8645)}[/tex] is approximately 47.5 degrees.
So, in the interval 0 degrees < x < 360 degrees, there is one value of x that satisfies the equation tan x = 0.8645, and it is approximately 47.5 degrees. It's important to remember that the inverse tangent function is a one-to-one function and its range is restricted to the interval -90° < x < 90°, so the value found represents the smallest angle in the interval 0° < x < 360° that has a tangent equal to 0.8645.

what pattern would you observe if everyone in the class were to bias their results to 5 heads and 5 tails?
In a coin flip experiment, you would see a pattern of 50/50 heads and tails if every student in the class skewed their findings to show 5 heads and 5 tails.
This is due to the fact that each participant purposefully altered their results to display an equal number of heads and tails.
It is crucial to remember that this pattern does not accurately reflect the chances of either getting heads or tails in a fair coin flip. The results cannot be taken as a representative sample of a fair coin flip because everyone purposefully slanted their findings. It is crucial to conduct experiments with appropriate controls and prevent results bias in order to acquire reliable findings.

Step-by-step explanation:
A population of bacteria is increasing at a rate of 7. 5% per hour. If there were originally 275 bacteria, which
of the following equations models the population of bactera h-hours after the original 275 bacteria were
measured?
The population of bacteria after h hours is 0.075.
Bacterial growth is proliferation of bacterium into two daughter cells, in a process called binary fission. Providing no event occurs, the resulting daughter cells are genetically identical to the original cell. Hence, bacterial growth occurs. Both daughter cells from the division do not necessarily survive. However, if the surviving number exceeds unity on average, the bacterial population undergoes exponential growth.
The equation that models the population of bacteria h-hours after the original 275 bacteria were measured is given by:
P(h) = 275 × [tex](1 + 0.075)^h[/tex]
p(h)=0.075
where P(h) is the population of bacteria after h hours and 0.075 is the growth rate of 7.5% per hour.
Therefore, the population of bacteria after h hours is 0.075.

When an object is dropped vertically from a platform, its height after t
t
seconds can be estimated with the formula shown.
h=h0−16t2
h=h0-16t2
h is the height of the object in feet.
h0 is the initial height of the object in feet.
t is the time in seconds after the drop.
Which equation and solution tells how long it takes the object to reach a height of 96 feet if its initial height is 208
The quadratic equation that we need to solve is:
96 = 208 - 16t^2
And the solution is t = √7
Which equation is the correct one?
We know that the height equation is the quadratic equation below:
h = h0 - 16t^2
If the initial height is 208, then we can write:
h = 208 - 16t^2
Now we can find how long takes to reach a height of 96 feet, then we can write:
96 = 208 - 16t^2
That is the equation we need to solve.
Solving that for t we will get:
96= 208 - 16t^2
16t^2 = 208 - 96
16t^2 = 112
t^2 =112/167
t = √7

The discount amount based on 35% discount offered on $89.95 is $31.5.
The discount amount can be calculated by the formula -
Final amount = original price - discount percentage × original price
The method of solving this formula will be to first multiply followed by subtraction according to PEMDAS rule.
Now, keep the values in formula
Final amount = 89.95 - 35/100 × 89.95
Performing multiplication and division on Right Hand Side of the equation
Final amount = 89.95 - 31.48
Now performing subtraction on Right Hand Side of the equation
Final amount = $58.47
Here we see that that the discount amount is $31.48
Round to nearest penny = $31.5

2. Seth’s father is thinking of buying his son a six-month movie pass for $40. With the pass, matinees cost $1.00. If matinees are normally $3.50 each, how many times must Seth attend in order for it to benefit his father to buy the pass?
Answer: The savings per movie with the pass is $3.50 - $1.00 = $2.50. For the pass to benefit Seth's father, Seth must attend enough movies such that the total savings is equal to or greater than $40.
Let's call x the number of times Seth must attend for the pass to benefit his father. Then:
$2.50x >= $40
Solving for x:
$2.50x/$2.50 >= $40/$2.50
x >= 16
So Seth must attend at least 16 movies in order for the pass to benefit his father.

The cumulative frequency and relative cumulative frequency for students who earned a score of 20 or lower on the quiz is 29; 58%. (option d)
Cumulative frequency refers to the running total of frequencies, or the sum of frequencies up to a certain point. In this case, the cumulative frequency is the number of students who scored 20 or lower on the quiz.
Relative cumulative frequency, on the other hand, expresses the cumulative frequency as a percentage of the total number of students in the sample. To find the relative cumulative frequency, we divide the cumulative frequency by the total number of students and multiply by 100.
Therefore, for students who scored 20 or lower on the quiz, the cumulative frequency is 29 and the relative cumulative frequency is 58% (29/50 * 100).

The value of z is found by dividing y by x, which results in z =[tex]-\frac{16}{63}$[/tex]
To solve for z, we can use the equation [tex]$x\cdot z = y$[/tex]. We know that [tex]$x = \frac{7}{8}$[/tex] and [tex]$y = -\frac{2}{9}$[/tex],
Therefore, we can enter these values into the equation as substitutes:
[tex]$\frac{7}{8} \cdot z = -\frac{2}{9}$[/tex]
Next, In order to separate z, we must divide both sides of the equation by [tex]$\frac{7}{8}$[/tex]:
[tex]$z = \frac{-\frac{2}{9}}{\frac{7}{8}}$[/tex]
To divide by[tex]$\frac{7}{8}$[/tex], The fraction can be rotated, then multiplied by its reciprocal, which is [tex]$\frac{8}{7}$[/tex]
[tex]$z = \frac{-\frac{2}{9}}{\frac{7}{8}} \cdot \frac{8}{7}$[/tex]
The fraction on the right can be made simpler as follows:
