For v = -4, 0, and 8 are not solutions of the equation 1 - 7v = - 69. The solution of the equation is v = 10.
Consider the equation,
1 - 7v = - 69
For the value of v = - 4,
1 - 7v = - 69
1 - 7 × - 4 = - 69
1 + 28 ≠ - 69
29 ≠ - 69
Hence, v = - 4 is not a solution.
For v = 10,
1 - 7v = - 69
1 - 7 × 10 = - 69
1 - 70 = - 69
- 69 = - 69
Therefore, v = 10 is a solution.
For the value of v = 0,
1 - 7v = - 69
1 - 7 × 0 = - 69
1 ≠ - 69
Hence, v = 0 is not a solution.
For the value of v = 8,
1 - 7v = - 69
1 - 7 × 8 = - 69
1 - 64 ≠ - 69
- 63 ≠ - 69
Hence, v = 8 is not a solution.

In a large population, 56% of the people have been vaccinated. If 5 people are randomly selected, what is the probability that at least one of them has been vaccinated?
Answers
The likelihood that someone has received a vaccination equals one minus the likelihood that no one has. The likelihood that a randomly chosen individual in a large population IS NOT immunized = 1 - 0.54 = 0.46.
The likelihood that the three randomly chosen individuals are not all immunized is 0.463, hence the likelihood that at least one of them has been immunized is 1 - 0.463.
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Answers
The correct responses for the arithmetic and exponential sequence and function are;
1. First part; 32 pennies
Second part; Approximately 50 days
2. 24.6 gallons
3,738.5 minutes
3. $67.2
Approximately 24 months
4. 1106.14 gallons
66.56 minutes
The difference is 1 is an arithmetic sequence while 3 is an exponential function
What is a an arithmetic sequence?An arithmetic sequence is a group of numbers in which the difference between subsequent terms is a constant
1. The given parameters are;
The initial amount Savannah placed in the piggy bank = 5 pennies
The amount given to Savannah each day = 3 pennies
Required;
First part;
The amount Savannah will have after 10 days
Solution;
The mathematical model for the situation is an arithmetic sequence or progression
The equation for an arithmetic progression is;
[tex]a_n = a_1 + (n - 1) \times d[/tex]
Where;
[tex]a_n[/tex] = The amount after n days
[tex]a_1 [/tex] = The first amount Savannah placed in the piggy bank = 5 pennies
n = The number of days
d = The common difference between the amount present in consecutive days = 3 pennies
The amount after 10 days is therefore;
[tex]a_{10} = 5 + (10 - 1) \times 3=32[/tex]
The money after 10 days is 32 pennies
Second part;
The number of days it would take for there to be $1.50 in the piggy bank.
Solution;
100 pennies = $1.00
Therefore;
$1.50 = 150 pennies
Which gives;
150 = 5 + (n - 1) × 3
(n - 1) × 3 = 150 - 5 = 145
(n - 1) × 3 = 145
n - 1 = 145 ÷ 3
n = 145 ÷ 3 + 1 ≈ 49.3 ≈ 50
It will take approximately 50 days for the amount in the piggy bank to be $1.50
2. The volume of the pool = 1,500 gallons
The initial amount of water in the pool = 5 gallons
The rate at which water enters the pool = 2 gallons in 5 minutes
Required;
First part
The volume of water in the pool after 50 minutes
Solution;
2 gallons in 5 minutes = (2/5) gallons/minute = 0.4 gallons/minute
Therefore;
[tex]a_{50} = 5 + (50 - 1) \times 0.4 =24.6[/tex]
After 50 minutes, 24.6 gallons will be in the pool
Second part;
The time it will take to fill the pool is given by the equation;
[tex]1500 = 5 + (n - 1) \times 0.4[/tex]
number
Which gives;
n = 3738.5
It will take 3,738.5 minutes to fill the pool
3. The formula for finding the amount in the account is the compound interest formula;
[tex]\displaystyle{A = P\cdot (1 + r)^n }[/tex]
Where;
A = The amount in the account after n months
P = The initial amount in the account = $50.0
r = The interest rate = 3.0%
n = The number of periods (months)
After 10 months, we have;
[tex]\displaystyle{A = 50 \times (1 + 0.03)^{10} \approx 67.2 }[/tex]
The amount in the account after 10 months is therefore, approximately $67.2
Second part;
Double the initial amount is 2×$50 = $100
Which gives;
[tex]100 = \displaystyle{50 \times (1 + 0.03)^{n} \approx 67.2 } [/tex]
Which gives;
n ≈ 23.45
Therefore it will take approximately 23.45 months or approximately 24 months for the amount to double
4. Using the exponential function formula, we have;
Number of 5 minutes in 50 minutes = 10
[tex] \displaystyle{1500 \times (1 - 0.03)^{10} \approx 1106.14} [/tex]
The water remaining after 50 minutes is approximately 1106.14 gallons
The time it takes for there to be less than 1,000 gallons in the pool is given as follows;
[tex] \displaystyle{ 1000= 1500 \times (1 - 0.03)^{n}} [/tex]
Which gives;
n = 13.3
Therefore;
The water in the pool will be less than 1000 gallons after 13.3, 5 minute periods or 13.3 × 5 minutes≈ 66.56 minutes

The sum of three mixed numbers is 24 4/5. Two of the number are 8 2/3 and 6 5/6. What is the third number?
Answers
The numerical value of the third number in an improper and mixed fraction form is 93/10 and 9 3/10 respectively.
What is the value of the third number?Given the data in the question;
Let 'x' represent the third number
Sum of the three numbers = 24 4/5First number = 8 2/3Second number = 6 5/6Third number = xFirst, convert the numbers form mixed fractions to improper fractions
Sum of the three numbers = 24 4/5 = ( 24×5 + 4 )/5 = 124/5
First number = 8 2/3 = ( 8×3 + 2 )/3 = 26/3
Second number = 6 5/6 = ( 6×6 + 5 )/2 = 41/6
Now, to determine the third value, equate the sum of the three numbers to the total and solve for x
26/3 + 41/6 + x = 124/5
( 156 + 123 )/18 + x = 124/5
( 279 )/18 + x = 124/5
31/2 + x = 124/5
x = 124/5 - 31/2
x = ( 248 - 155 )/10
x = ( 93 )/10
x = 93/10
x = 9 3/10
Therefore, the value of the third number is 93/10 or 9 3/10.

Richard and teo have a combine age of 19 Richard is 4 years older than twice teo age how old are Richard and teo
Answers
r + t = 19
2t + 4 = r
(2t + 4) + t = 19
Let’s remove the parenthesis and combine like terms:
2t + 4 + t = 19
→ 3t + 4 = 19
Now we can subtract 4 from both sides:
3t + 4 = 19
→ 3t = 15
Finally, division of 3 on both sides will evaluate Teo’s age:
3t = 15
→ t = 5
We can plug in Teo’s age for t and solve for Richard’s age now:
(2t + 4) + t = 19
→ 2(5) + 4 + 5 = 19
10 + 4 + 5 = 19
Richard is 14 because 19 - 5 = 14.
Answer Recap: Richard’s age is 14, and Teo’s age is 5.

Answers
Answer:
104 ;108;112;116;120;124;128;132;136 ;140;144;148
Answer:
104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148
Step-by-step explanation:
A multiple of 4 can generally be defined as divisible by 4.
We can define an equation for it: [tex]4n[/tex] where n is an integer.
From here we can see that if n=25, we have a number of 100 which indeed is a multiple of 4 since dividing it by 4 results in 25 which makes sense since 100 is the result of 4 * 25.
Now starting from 100 (excluding 100 since between 100 and 150), or n=25, we can increase the value of the number by 4, or n by 1 which is doing the same thing.
So start at 100, then 100+4 = 104, then 104+4=108 and so on... until you reach a number greater than or equal to 150, and if it is 150 make sure to exclude it since it says between 100 and 150 which implies it's excluding the end points.
This gives us a result of: 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148

What are algebraic expressions?Algebraic expressions are simply described as arithmetic expressions that are made up of arithmetic terms, constants, variables, factors and coefficients.
These expressions are also made up of arithmetic operations which includes;
ParenthesesBracketDivisionMultiplicationAdditionSubtraction, etcBased on the information given, we have;
x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 + x + 7 = 124
Now, collect like terms, we get;
8x + 28 = 124
8x = 124 - 28
Subtract like terms
8x = 96
To determine the value of x, make it the subject by dividing both sides by 8, we have;
8x/8 = 96/8
x = 12
Then,
x = 12
x + 1 = 13
x + 2 = 14
x + 3 = 15
x + 4 = 16
x + 5 = 17
x + 6 = 18

A scientist is determining the mass of 22000 molecules of oxygen. How many significant digits should be in the solution?
Answers
Based on the mass of the molecules of oxygen that the scientist determined, the number of significant digits in the solution is 2.
How to count significant digits?When counting the significant figures in a number, the first rule is that any digit that isn't a zero would be considered a significant digit.
Zeros that are trailing in a number however, and are not considered decimals, are not counted as significant digits. This means that both the 2 number 2s in the figure will be significant figures.
The three zeros are trailing but not decimals so they are not considered significant. This means that in the mass of oxygen according to the scientist, has only 2 significant figures.

Answers
Answer:
Yes, this is an arithmetic sequence.
The difference is -3, so a(n+1) = a(n) - 3
The 21st term is -53, calculated as follows:
a(21) = 7 + (21 - 1)(-3) = -53
The next three terms are -5, -8, and -11.
