Given the function f(x)=x^2-8x+13f(x)=x, determine the average rate of change of the function over the interval −1≤x≤6.
Answers
Given:
Consider the given function is:
[tex]f(x)=x^2-8x+13[/tex]
To find:
The average rate of change of the function over the interval [tex]-1\leq x\leq 6[/tex].
Solution:
The average rate of change of the function f(x) over the interval [a,b] is:
[tex]m=\dfrac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
We have,
[tex]f(x)=x^2-8x+13[/tex]
At [tex]x=-1[/tex],
[tex]f(-1)=(-1)^2-8(-1)+13[/tex]
[tex]f(-1)=1+8+13[/tex]
[tex]f(-1)=22[/tex]
At [tex]x=6[/tex],
[tex]f(6)=(6)^2-8(6)+13[/tex]
[tex]f(6)=36-48+13[/tex]
[tex]f(6)=1[/tex]
Now, the average rate of change of the function f(x) over the interval [tex]-1\leq x\leq 6[/tex] is:
[tex]m=\dfrac{f(6)-f(-1)}{6-(-1)}[/tex]
[tex]m=\dfrac{1-22}{7}[/tex]
[tex]m=\dfrac{-21}{7}[/tex]
[tex]m=-3[/tex]
Therefore, the average rate of change of the function f(x) over the interval [tex]-1\leq x\leq 6[/tex] is -3.

D. The distributions for both towns are symmetric.
Answers
Answer:
The answer is B.
Step-by-step explanation:
As you can see, box plot A is symmetrical so that applies to answers A and B. However, box B is very skewed to the right which makes it positively skewed so answer B is the only one that matches the correct description of the two box and whisker plots.
We can conclude that the distribution for town A is symmetric, but the distribution for town B is positively skewed.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
The distribution for town A is symmetric, but the distribution for town B is positively skewed.
We can determine the skewness of the distributions by comparing the position of the median with respect to the quartiles.
In town A,
The median (30) is located at the center of the box, and the first and third quartiles (20 and 40, respectively are equidistant from the median.
This indicates a symmetric distribution.
In town B,
The first and third quartiles (20 and 30, respectively) are closer to the median (25) on the left-hand side of the box than on the right-hand side. This indicates a positively skewed distribution.
Therefore,
We can conclude that the distribution for town A is symmetric, but the distribution for town B is positively skewed.

The critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
The t-distribution with 8 degrees of freedom has probability 0.10 to the right of t.
That is, df = 8,
α = 0.10 by using these values, the critical value of t is obtained.
From the t-distribution table:
The critical value is 1.3968.
The critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.
Therefore, the critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.

Jenny is throwing a surprise birthday party for her best friend Katie. She has decided to make Katie’s favorite dish, meat loaf. There will be a total of 40 people at the party. Answer the following questions:
• The recipe says it serves 8 people. By what number should Jenny multiply each ingredient to make enough meat loaf for everyone? 5
• The recipe calls for 1 1/2 lbs. of ground beef. How much ground beef will Jenny need to make enough meat loaf for everyone?
• Jenny will be serving milk with the meal. She plans on using 8 oz. glasses. How many gallons of milk does she need to make sure everyone gets one glass of milk?
Answers
Answer:
The answer is below
Step-by-step explanation:
a) The recipe for the meat loaf used by Jenny can serve a total of 8 people. Since there are 40 people in total to serve, the number of each ingredient needed is:
Number of each ingredient = total number of people / number of people served by one recipe
Number of each ingredient = 40 / 8 = 5
b) Since each recipe contains 1 1/2 lb (1.5 lbs) of ground beef, the total amount of ground beef needed to feed everyone is:
Total amount of ground beef = 1.5 lbs * 5 = 7.5 lbs
c) Since one serving would require 8 oz of milk. To serve everyone, the amount of milk needed is:
Amount of milk = 40 people * 8 oz = 320 oz
128 oz = 1 gallon
Amount of milk = 320 oz * 1 gallon / 128 oz = 2.5 gallon
The quantity of the recipe needed for a given number of people is found
by a multiple of the recipe for 8 people.
First question: The number with which to multiply the ingredient is 5.Second question: The amount of ground beef needed is 7.5 lbs.Third question: The number of gallons of milk needed is 2 gallons.Reasons:
The total number of people at the party = 40 people
The number of people the recipe serves = 8 people/recipe
First question:
The number Jenny should multiply the ingredient to make enough for everyone is [tex]\mathbf{\dfrac{40 \ people}{8 \, people \, per \, recipe}} = 5 \times Recipe[/tex]
Therefore;
To make enough meat loaf for everyone, Jenny should multiply each ingredient by 5.
Second question:
The amount of ground beef required = [tex]1\frac{1}{2}[/tex] lbs.
Amount of ground beef required for everyone = 5 × [tex]\mathbf{1\frac{1}{2}}[/tex] lbs = 7.5 lbs.
Third question:
The volume of each glass of milk Jenny is serving = 8 oz.
The number of glasses of milk Jenny need = 40 glasses
The volume of the 40 glasses = 40 × 8 oz. = 320 oz.
Volume of one gallon (imperial) = 160 fluid ounce = 160 oz.
Therefore;
320 oz = 2 × 160 oz. = 2 × 1 gallon = 2 gallons
The number of gallons of milk Jenny needs to make sure everyone gets
one glass of milk is 2 gallons of milk.

El interior de un tanque que contiene agua, tiene una presión manométrica de 300 kPa. ¿Qué profundidad tiene el tanque de agua?
Answers
Respuesta:
30,6 metros
Explicación paso a paso:
Dado :
Presión = 300 Kpa
Usando la fórmula que relaciona la presión y la profundidad:
Presión = profundidad * aceleración debida a la gravedad * densidad del agua
Densidad del agua = 1000 kg / m³
Presión = 300Kpa = 300 * 10 ^ 3 Pa
300 * 10 ^ 3 Pa = profundidad * 9,8 * 1000
300000 = profundidad * 9800
Profundidad = 300000/9800
Profundidad = 30,612
Profundidad = 30,6 m

Step-by-step explanation:
Area of the shaded portion = Area of semicircle - Area of the right triangle
Area of semicircle = πr²/2
Area of semicircle = 3.14(6)²/2
Area of semicircle = 3.14 * 18
Area of semicircle = 56.52
Area of triangle = 1/2 * base * height
Get the height using the SOH CAH TOA identity

H = 12sin60
H = 12(0.8660)
H = 10.39
Get the base
12² = b²+10.39²
144 = b²+108
b² = 144 - 108
b² = 36
b = 6
Area of triangle = 1/2 * 6 * 10.39
Area of triangle = 3 * 10.39
Area of triangle = 31.17
Area of shaded portion = 56.52 - 31.17
Area of shaded portion = 25.35
