According to the given statement;

If ​P(A)=0.9​, ​P(B)​=0.1, and A and B are​ independent, ​ P(A and​ B)=0.09

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

125 and 216 are two perfect cubes

The average rate of change is 1.625.

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.

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.

Answer:26

Step-by-step explanation:

x - .35x = 16.90

x(1 - .35) = 16.90

x(.65) = 16.90

x = 16.90/.65

x = $26

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).

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(x, y) = (6, 2)

B(x, y) = (12, 2) - 0.667 · (6, 2)

B(x, y) = (8, 0.667)             FALSE

A(x, y) = (8, 1)

B(x, y) = (12, 2) - 0.667 · (8, 1)

Answer:

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

The initial amount and rate of change given a table for a linear function are $65 and $86, respectively

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

Product of  (3a^2b^4)*(-8ab^3)

Multiplication is one of the four basic arithmetic operations, alongside addition, subtraction, and division. Multiplication essentially means the repeated addition of groups of equal sizes. While solving multiplication problems, one-digit numbers can be multiplied in a simple way by using the multiplication tables, but for larger numbers, we split the numbers into columns using their respective place values, like ones, tens, hundreds, thousands, and so on.

The multiplication formula is expressed as, Multiplicand × Multiplier = Product; where:

Multiplicand: The first number (factor).

Multiplier: The second number (factor).

Product: The final result after multiplying the multiplicand and multiplier.

Slope (m) = rise/run.

Find the slope (m) of the graph at the right.

Slope (m) = rise/run = 1 units/2 units

Slope (m) = 1/2.

Any possible equation of the line should have a slope of 1/2.

y - 2 = 1/2(x - 4), y - 2 = 1/2(x + 4), and y - 4 = 1/2(x - 2) are the only equations that has a slope of 1/2.

Using a point on the line, say (0, 3), substitute x = 0 and y = 3 into each of the three equations to check if the equation is true.

y - 2 = 1/2(x - 4)

3 - 2 = 1/2(0 - 4)

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%
