3 --------------------------- 18 ------------------- 0.144
4 --------------------------- 29 ------------------- 0.232
5 --------------------------- 37 ------------------- 0.296
6 --------------------------- 6 ------------------- 0.048
Step-by-step explanation:
Required: Complete the table
The table is divided into 3:
1. Result of Roll
2. Frequency (F)
3. Experimental Probability (P)
The relationship between (2) and (3) is:
[tex]P = \frac{F}{N}[/tex]
Where
N = Number of Rolls
N = 125
For Roll of Result = 2
Frequency = 13
The probability is calculated as thus:
[tex]P = \frac{13}{125}[/tex]
[tex]P = 0.104[/tex]
For Roll of Result = 3
Probability = 0.144
The Frequency is calculated as thus:
[tex]0.144 = \frac{F}{125}[/tex]
[tex]F = 0.144 * 125[/tex]
[tex]F = 18[/tex]
For Roll of Result = 4
Frequency = 29
The probability is calculated as thus:
[tex]P = \frac{29}{125}[/tex]
[tex]P = 0.232[/tex]
For Roll of Result = 5
Probability = 0.296
The Frequency is calculated as thus:
[tex]0.296 = \frac{F}{125}[/tex]
[tex]F = 0.296* 125[/tex]
[tex]F = 37[/tex]
For Roll of Result = 6
Frequency = 6
The probability is calculated as thus:
[tex]P = \frac{6}{125}[/tex]
[tex]P = 0.048[/tex]
For Roll of Result = 1.
To get the frequency; we subtract the sum of frequencies of roll of results 2 to 6 from the total number of rolls.
In other words:
Frequency of 1 = Total Rolls - (Frequency of 2 + Frequency of 3 + Frequency of 4 + Frequency of 5 + Frequency of 6)
Frequency of 1 = 125 - (13 + 18 + 29 + 37 +6)
Frequency of 1 = 125 - 103
Frequency of 1 = 22
The probability is calculated as thus:
[tex]P = \frac{F}{N}[/tex]
[tex]P = \frac{22}{125}[/tex]
[tex]P = 0.176[/tex]

Find three consecutive odd integers such that the sum of the smallest number and
twice the middle number is 10 more than the largest number.
Answer:
As the first number is 5, the second will be 7, and the third will be 9.
Step-by-step explanation:
First, let's break down what the information is telling us.
"three consecutive odd integers" means each number is 2 away from each other. So if we were to assign the variable x as the first number, the second would be x + 2 and the third would be x + 4
"sum of the smallest number and twice the middle number" refers to adding the first number and 2 times the second number. So we would write:
x + 2(x + 2)
"is 10 more than the largest number" connects the second part to an equation. This is saying the third number plus 10. So for this, we would write:
(x + 4) + 10
Now we join the information that we have written mathematically into an equation. Since we have an equation, we can solve for the first number, and hence the second and third numbers.
x + 2(x + 2) = (x + 4) + 10
x + 2x + 4 = x + 14
3x + 4 = x + 14
2x = 10
x = 5
As the first number is 5, the second will be 7, and the third will be 9.
The key idea for solving this question is to define a variable and connect it to an equation using the information provided. Try to think about how much information is needed and how many variables need to be defined.
The straight line L has equation y = 2x - 5
Find an equation of the straight line perpendicular to L which passes through (-2, 3).
Answer:
slope of perpendicular line - m = -1/2
passing through (-2,3)
thus,
y-3 = -1/2 (x+2)
or y = -1/2x +2
An equation of the straight line perpendicular to [tex]\boldsymbol{y=2x-5}[/tex] which passes through [tex]\boldsymbol{(-2,3)}[/tex] is [tex]\boldsymbol{x+2y-4=0}[/tex]
An equation of a straight line is [tex]\boldsymbol{y=2x-5}[/tex]
Compare this equation with the form [tex]\boldsymbol{y=mx+b}[/tex] where [tex]\boldsymbol{m,b}[/tex] denote slope and [tex]\boldsymbol{y-}[/tex]intercept respectively.
So,
[tex]\boldsymbol{m=2}[/tex]
As the slopes of two perpendicular lines are negative reciprocals of each other, slope of a required line is equal to [tex]n=\frac{-1}{2}[/tex]
Take [tex](x_1,y_1)=(-2,3)[/tex]
Equation of the required line is [tex]\boldsymbol{y-y_1=n(x-x_1)}[/tex]
[tex]y-3=\frac{-1}{2}(x+2)[/tex]
[tex]2y-6=-1(x+2)[/tex]
[tex]x+2y-4=0[/tex]

A simplified model for the concentration (micrograms/milliliter) of a certain slow-reacting antibiotic in the bloodstream t hours after injection into muscle tissue is given by
f(t) = t2 ·e−t/16, t ≥ 0.
When will there be maximum concentration?
In the units given, how much is the maximum concentration?
When will the concentration dip below a level of 20.0?
Estimate from a graph when the concentration function changes concavity
Answer:
A) T = 24
b) 77.953
c) t > 63.78 , t < 5.6
d) (7.029,27.5) and (40.97,55.23)

x + 3y = 5
-x + 6y = 4
Solve the system of equations.
A) x = 1, y = 2
B) x = 2, y = 1
C) x = 1, y = 1
D) x = 0, y = 2
Answer = B) x = 2, y = 1
As, x + 3y = 5 = 2 + 3(1) = 5, so 2 + 3 = 5
-x + 6y = 4
-2 + 6(1) = 4
-2 + 6 = 4
So, answer = (B)
For each statement, select the correct null hypothesis, H0, and alternative hypothesis, Ha, in symbolic form.1. A certain type of hummingbird is known to have an average weight of 4.55 g. A researcher wonders if hummingbirds (of this same type) living in the Grand Canyon differ in weight from the population as a whole. The researcher finds a sample of 30 such hummingbirds from the Grand Canyon and calculates their average weight to be 3.75 g.A. H0:x¯=4.55, Ha:x¯<4.55.B. H0:μ=3.75, Ha:μ≠3.75.C.

According to the Merck Veterinary Manual, the average resting heart rate for a certain type of sheep dog is 115 beats per minute (bpm). A Montana farmer notices his aging sheep dog has been acting more lethargic than usual and wonders if her heart rate is slowing.

Answer:
F.) H0:μ=4.55, Ha:μ≠4.55
A.) H0:μ=115, Ha:μ<115
H0:μ=69 , Ha:μ>69
Step-by-step explanation:
The null and alternative hypothesis are used in hypothesis testing.
Generally, both hypothesis negatives each other, with the alternative being the opposite of the null hypothesis.
1)the mean value of the population is 4.55 ; the researcher aims to test if the mean value differs from thus value, hence, Alternative ; μ ≠ 4.55
2.) The mean resting heart rate is said to be 115 ; this is the null claim. The reaesrch aims to test if heart rate slows down with age. Hence, the alternative will be to show that mean rate lesser Than 115 as claimed (μ < 115)
3.) Theean height of the population is claimed to be 69. Researcher aims to test if some people within the population have mean height abive this said height. (μ > 69)

Joe puts his trading card collection in a folder Each page of the folder holds 9 cards. He has 1,356 trading cards Complete the statement to tell the number of pages
Joe completely fills and the number of trading cards he has left over
If he has 1,356 cards and each page he has holds 9 cards, we don't know how many pages he has, so that will be x
1,356/9x -----1,356 (# of cards) divided by 9 (cards each page holds) times x (# of pages)
Divide 9x by 9 to get x by itself -----9x/9=x
Then, what you do to one side you must do to another so divide 1,356 by 9 -----1,356/9=150.667
He needs 150 pages and has .667 left over.
If zeina has seven times as many books as ali if zeina gave ali 15 books they would eash have the same number of books how many books did each have
Answer:
Zeina had 35 books and Ali had 5 books
Step-by-step explanation:
Equations
We know Zeina has seven times as many books as Ali. If we call
x = Number of books Ali has
Then Zeina has
7x = Number of books Zeina has
We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:
x + 15 = 7x - 15
Adding 15:
x + 15 +15 = 7x
Subtracting x:
15 +15 = 7x - x
Operating:
30 = 6x
Dividing by 6:
x = 30 / 6
x =5
7x = 35
Thus Zeina had 35 books and Ali had 5 books
