The average rate of change is 1.625.
How to find the average rate of change?The average rate of change in height for chuck can be found as follows:
The average rate of change is a measure of how much the function changed per unit, on average, over that interval.
Therefore,
average rate of change = change in y / change in x
Therefore,
(10, 51)(18, 64)
average rate of change = y₂ - y₁ / x₂ - x₁
x₁ = 10
x₂ = 18
y₁ = 51
y₂ = 64
Therefore,
average rate of change = 64 - 51 / 18 - 10
average rate of change = 13 / 8
average rate of change = 1.625
Therefore, the average rate of change is 1.625.

What is probability of event?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition 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 likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other possible outcomes and the coin is fair, the odds of both the outcomes, "heads" and "tails," are equally likely to occur. As a result, the probability of either outcome is half.
According to the given value;
P(A) = 0.9
P(B) = 0.1
A and B independent;
We know that independent
P(A∩B) = P(A) · P(B)
= (0.9)*(0.1)
=0.09
P(A∩B) =0.09
hence, If P(A)=0.9, P(B)=0.1, and A and B are independent, P(A and B)=0.09

Si 14 % de un número es 160 ¿cuánto es de 10%
What is the 10% of number in which the 14% is 160
What does percentage mean?Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it. A% is a number that has neither dimensions nor a defined unit of measurement.
being that,
14% × x = 160
14/100 × x = 160
x = 160 × 100/14
x = 1142.86
The current value is 1142.86.
10% of the total number must be located.
to say,
10% x 1142.86 = 10 / 100 x 1142.86
= 114.286
Consequently, 114.286 is the value of the 10% of the number.

The number of cities in a region over time is represented by the function C(x)=2.9(1.05)^x. The approximate number of people per city is represented by the function P(x) = (1.05) (1.05) 3+5
Which function best describes T (2), the approximate population in the region?
OA. T (2) 2.9(1.05) 3²+5x
OB. T (T) (6.09)^4x+5
OC. T (1) 2.9(1.05)^4x+5
OD. T(x)= (3.045)^x + (1.05)^3x+5
The correct option is option C.
T(x) = 2.9(1.05)⁴ˣ ⁺ ⁵
Given the number of cities in a region is represented by the function:
C(x) = 2.9(1.05)ˣ
The approximate number of people per city is represented by the function P(x) = (1.05)³ˣ⁺⁵
we are asked to determine T(x), the approximate population in the region = ?
combine C(x) and P(x)
therefore, T(x) = C(x)P(x)
T(x) = 2.9(1.05)ˣ(1.05)³ˣ⁺⁵
During multiplication, when bases are same then powers are added.
T(x) = 2.9(1.05)³ˣ⁺ˣ⁺⁵
T(x) = 2.9(1.05)⁴ˣ⁺⁵
Hence we get the approximate function of T(x) as T(x) = 2.9(1.05)⁴ˣ⁺⁵

HELP!!!! Finding the initial amount and rate of change given a table for a linear function
The initial amount and rate of change given a table for a linear function are $65 and $86, respectively
How to find the initial amount and rate of change given a table for a linear function?The table of linear function represents the given parameter
On the table, we have the following points
(x, y) = (6, 476) and (10, 736)
The rate of change is calculated as
Rate = (y2 - y1)/(x2 - x1)
So, we have
Rate = (736 - 476)/(10 - 6)
Evaluate
Rate = 65
This means that the rate of change is $65
The initial amount is calculated as
y = m(x - x1) + y1
Where
m = 65
So, we have
y = 65(x - x1) + y1
Using one of the points, we have
y = 65(x - 6) + 476
Set x = 0
So, we have
y = 65(0 - 6) + 476
Evaluate
y = 86
Hence, the initial amount and rate of change given a table for a linear function are $65 and $86, respectively

much will she have to pay then?

$614.49.
$641.69.
Answer: if my math is correct i think its b
Step-by-step explanation:
The correct option is option C that is the due amount which Tina needs to pay at the end of fourth month is $ 614.4.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
It is given that Tina needs to purchase a refrigerator as replacement for $1100.
The monthly periodic rate if balance is not paid by the second month = 1.2 %
The amount she paid by the second month = $500
The due amount is :
= 1100 - 500
= $600
This amount she decided to pay by end of fourth month or after two more months.
Let's assume the amount she had to pay now at the end of fourth month is x then it given by :
= 600 + ( 600 × [tex]\frac{1.2}{100}[/tex] × 2)
= 600 + ( 12 × 1.2 )
= 600 + 14.4
= $ 614.4
Therefore , the correct option is option C that is the due amount which Tina needs to pay at the end of fourth month is $ 614.4.

point x is located at (4.8, 0.8) and divides line segment AB in ratio 2:3 select two possible sets of endpoints for segment AB
The possible endpoints are: (i) A(x, y) = (6, - 2) and B(x, y) = (3, 5), (ii) A(x, y) = (4, 4) and B(x, y) = (6, - 4).
What are the possible locations of the endpoints of a line segment?
In this problem we know the location of the midpoint and the line segment ratio. There are two posibilities according to the definition of line segment ratio:
AX / BX = 2 / 3 (1)
BX / AX = 2 / 3 (2)
And now we solve for each case:
Case 1
X(x, y) = A(x, y) + (2 / 5) · [B(x, y) - A(x, y)]
X(x, y) = (3 / 5) · A(x, y) + (2 / 5) · B(x, y)
(4.8, 0.8) = (3 / 5) · A(x, y) + (2 / 5) · B(x, y)
(4.8, 0.8) = 0.6 · A(x, y) + 0.4 · B(x, y)
(4.8, 0.8) - 0.6 · A(x, y) = 0.4 · B(x, y)
(12, 2) - 1.5 · A(x, y) = B(x, y)
B(x, y) = (12, 2) - 1.5 · A(x, y)
Now we proceed to check each choice:
A(x, y) = (6, - 2)
B(x, y) = (12, 2) - 1.5 · (6, - 2)
B(x, y) = (3, 5) TRUE
A(x, y) = (6, 2)
B(x, y) = (12, 2) - 1.5 · (6, 2)
B(x, y) = (3, - 1) FALSE
A(x, y) = (8, 1)
B(x, y) = (12, 2) - 1.5 · (8, 1)
B(x, y) = (0, 0.5) FALSE
A(x, y) = (2.4, 0.4)
B(x, y) = (12, 2) - 1.5 · (2.4, 0.4)
B(x, y) = (8.4, 1.4) FALSE
A(x, y) = (4, 4)
B(x, y) = (12, 2) - 1.5 · (4, 4)
B(x, y) = (6, - 4) TRUE
A(x, y) = (1.8, - 1.2)
B(x, y) = (12, 2) - 1.5 · (1.8, - 1.2)
B(x, y) = (9.3, 3.8) FALSE
Case 2
X(x, y) = B(x, y) + (2 / 5) · [A(x, y) - B(x, y)]
X(x, y) = (2 / 5) · A(x, y) + (3 / 5) · B(x, y)
(4.8, 0.8) = (2 / 5) · A(x, y) + (3 / 5) · B(x, y)
(4.8, 0.8) = 0.4 · A(x, y) + 0.6 · B(x, y)
(4.8, 0.8) - 0.4 · A(x, y) = 0.6 · B(x, y)
(12, 2) - 0.667 · A(x, y) = B(x, y)
B(x, y) = (12, 2) - 0.667 · A(x, y)
Now we proceed to check each choice:
A(x, y) = (6, - 2)
B(x, y) = (12, 2) - 0.667 · (6, - 2)
B(x, y) = (8, 3.334) FALSE

(a) What was the initial sum of money invested?
(b) What was the percentage rate of return per annum on the investment?
Answer- A) 59,600 ; B) 4.12% per year.
Explanation
84,200 minus 24,600 is 59,600. This means the originally cost put into the account was 59,600.
Next we have to divide the amount of interest earn into the number of years that the amount was accumulated. 24,600 divided by 10 is 2460. This means that each year 2,460 were earned in interest. 59,600 divided into 2,460 is 0.0412751678. This rounds to .0412 If we move our decimal to a percentage this leaves us with 4.12% This means that annual interest on the investment is 4.12%
