fiona asked 150 students to select their favorite fruit and then recorded the results in the bar graph below. fiona will ask another 45 students to select their favorite fruit. based on the information in the bar graph, how many more students from the next 45 are likely to select oranges rather than bananas their favorite fruit?
Answers
The number of students that are more likely to select oranges rather than bananas their favorite fruit from the next 45 is; 3.
What no. of students from the next 45 are likely to select oranges rather than bananas their favorite fruit?It follows from the task content that the number of students surveyed initially is 150 and only, 30 -20 = 10 students preferred orange to bananas.
On this note, it follows that the number of students who prefer oranges rather than bananas from the next 45 is; = (45 × 10)/150 = 3.

What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, to find the slope, we need to find the derivative at (4,3), using implicit differentiation. Hence:
[tex]2x\frac{dx}{dx} + 2y\frac{dy}{dx} = 0[/tex]
[tex]\frac{dy}{dx} = -\frac{x}{y}[/tex]
[tex]\frac{dy}{dx} = -\frac{4}{3}[/tex]
Then:
[tex]y = -\frac{4}{3}x + b[/tex]
We use point (4,3) to find b, hence:
[tex]y = -\frac{4}{3}x + b[/tex]
[tex]3 = -\frac{16}{3} + b[/tex]
[tex]b = \frac{25}{3}[/tex]
Hence, the equation is:
[tex]y = \frac{-4x + 25}{3}[/tex]

Given f (x)= x-4/x^2+13x+36, which of the following is true? f(x) is decreasing for all x > –9 f(x) is increasing for all x < –9 f(x) is increasing for all x > –4 f(x) is decreasing for all x > –4
Answers
The simplified expression of the function [tex]f (x)= \frac{x-4}{x^2+13x+36}[/tex] is
[tex]f (x)= \frac{x-4}{(x+9)(x+4)}[/tex]. f(x) is increasing for all x > –4
What is a function?A function is defined as a relation between the set of inputs having exactly one output each.
The function expression is given as:
[tex]f (x)= \frac{x-4}{x^2+13x+36}[/tex]
Expand the denominator
[tex]f (x)= \frac{x-4}{x^2+4x+9x+36}[/tex]
Factorize the denominator
[tex]f (x)= \frac{x-4}{x(x+4)+9(x+4)}[/tex]
Factor out x + 9
[tex]f (x)= \frac{x-4}{(x+9)(x+4)}[/tex]
Hence, the simplified expression of the function [tex]f (x)= \frac{x-4}{x^2+13x+36}[/tex] is
[tex]f (x)= \frac{x-4}{(x+9)(x+4)}[/tex]. f(x) is increasing for all x > –4

There is a “family” of Z distributions?
Answers
Reason:
There is only one Z distribution, which is also known as the standard normal distribution. This distribution has a mean of mu = 0 and a standard deviation of sigma = 1. So unless you consider a family to only have one member, then I'd consider the statement your teacher gave you to be false.
On the other hand, if we were talking about the student T distribution, then this is a family of function curves. The reason being is that the degrees of freedom (df) will change the shape of said curve. The value of df will depend on the sample size n. Recall that df = n-1. As n gets larger, then the T distribution curves will slowly start to look like the Z distribution. For n > 30, the difference is so very minor that it's easier to swap over to the Z distribution even if you don't know sigma.
In other words, there is a family of T distribution curves in which slowly approach to mimicking the Z distribution curve when n is large (usually n > 30).

Answer:
no

plug 6 in for x and 2 in for y, as (x, y) = (6, 2)
first equation:
y = 1 * y
2(6) + 1(2) = 10
12 + 2 = 10
14 = 10
this is false
second equation:
3(6) + 2(2) = 10
18 + 4 = 10
22 = 10
this is false
for this to be a solution, it must fit into both equations. as this fits into neither, this is not a solution
Jillian was asked to translate the expression 9 + n into words. She wrote “a number increased by nine.” Which best describes the accuracy of Jillian’s answer?
It is incorrect. The variable would come first in the expression “a number” (n) “increased by” (+) “nine” (9).
It is incorrect. The phrase “increased by” refers to the inequality symbol “greater than” (>), not addition.
It is correct. A number increased by nine (n + 9) is the same as nine increased by a number (9 + n).
It is incorrect. A number increased by nine refers to a multiplication expression (n times 9).

Which of the following statements about the expected value of a random experiment is true? A. The expected value is the value you will get after one trial. B. The expected value is the average of the values after 100 trials. C. As the number of trials gets larger, the average of the trials approaches the expected value. D. The expected value never actually equals the average of the trials. Please select the best answer from the choices provided A B C D
Answers
Answer: C. As the number of trials gets larger, the average of the trials approaches the expected value
Step-by-step explanation:
The expected value is the weighted average of the results of an experiment. As more trials go on, the actual average is more likely to get closer to the expected value. The expected value can be explained as the theoretical result after infinity trials, so as the number of trials approaches infinity, the result will approach the expected value.
