Based on the parameters in the question, the value of probability P(A) is 0.60

The given parameters from the tree diagram are:

The probability is calculated using the following probability formula

P(A) = P(A and D) + P(A and C)

Substitute the known values in the above equation

P(A) = 0.6 * 0.7 + 0.6 * 0.3

Evaluate the products

P(A) = 0.42 + 0.18

Evaluate the sum

P(A) = 0.60

Hence, the value of the probability of A is 0.60

If a person is randomly selected, the probability provided the condition is P(Female | Suwanee) is 1/3.

Probability is used to determine the odds in favor or against a random event happening. The odds in favor or against an event happening has a probability value that lies between 0 and 1.

The higher the odds of an event happening, the closer the probability value would be to 1. If it is equally likely that the event might happen or not happen, the probability value will be 0.5.

P (Female | Suwanee) is the probability that a person is female given that the person is from Suwanee.

P (Female | Suwanee) = total number of females from Suwanee / total number of people from Suwanee

8 / 24 = 1/3

the value of x are that makes it true

It will take Plant A 5 days to be the same height as Plant B and this can be calculated through unitary method of mathematical calculation.

The unitary technique used in here involves at first determining the value of a particular single unit, that is thus followed by the value of the necessary number of units.

A single or type of a distinct unit is referred to by the word of unitary.

Therefore, the goal of this strategy is to establish values in reference to a single unit.

The unitary technique, for instance, can be used to calculate how many kilometers a car will go on one liter of gas if it travels 44 km on two liters of fuel.

Plant A initial height = 2 inches

Growth rate = 14 inches/ week

= 2 inches/ day

Plant B initial height = 12 inches

Growth rate = 1 inch/ week

After 5 days we can see that plant A will be

2 + (5 x 2) = 12 inches

this is the same height as that of Plant B.

Choose A

( A is the answer <3)

We have a randomly selected prize out of 9 objects (4 rings, 4 headsets and 1 camera).

a) We have to calculate the odds in favor of Mary winning a ring.

The odds can be expressed as the proportion (or quotient) between the probabilities of winning a ring and the probabilities of not winning a ring.

This will also be equal to the number of outcomes that will be a ring (4 elements are rings) divided by the number of outcomes that are not a ring (5 elements are not a ring):

b) Now, we have to calculate the odds against Mary winning a ring.

This will be the inverse of the previous result, as we have to divide the probability of not winning a ring by the probability of winning.

We can then write:

Answer:

a) 4 : 5

b) 5 : 4

ANSWER:

Regular pay is $383.2

Overtime rate is $14.37

Overtime pay is $114.96

Gross pay is $498.16

STEP-BY-STEP EXPLANATION:

Assuming the overtime multiplier is 1.5 and the standard work week is 40 hours. Therefore, we calculate the regular payment like this:

The overtime rate would be the value of the normal payment times the overtime multiplier, like this

Then we multiply the number of additional hours to the 40 hours allowed, that is, 8 (48 - 40), for which one gives overtime pay

Now the gross pay would be the sum of the regular payment with the overtime payment:

To do the operation, first the numerator and denominator by 100:

Now simplify

If the saving compounded monthly at an interest rate of 6%. The amount you need to deposit a month is $8,302.

Using this formula  to determine the principal amount

P = A / (1 + r/n) ^nt

Where:

P =  principal = ?

A = amount = $50,000

r = interest rate = 6%

t = time  = 30  

Now let  plug in the formula

P = $50,000 / (1 + 0.06/12) ^( 12 × 30 )

P = $50,000 / (1 + 0.005) ^ 360

P = $50,000 / (1.005)^360

P = $50,000 / 6.022575

P = $8,302

Therefore $8,302.10 is the amount deposited.

We say that two lines are perpendicular if the slope of one line is minus the multiplicative inverse of the slope of the other one; mathematically, this amounts to the following equation:

In this case, the slope of our line is 4/7. Then the slope (m) of any line perpendicular to it must satisfy

Solving this equation for m, we get

The end behaviours of the functions are

Function 1

The equation of the function is given as

f(x) = 6x⁹ - 6x⁴ - 6

Calculate f(∝) and f(-∝)

So, we have

f(∝) = 6(∝)⁹ - 6(∝)⁴ - 6

Evaluate

f(∝) = ∝ - ∝ - 6

So, we have

f(∝) = ∝

Also, we have

f(-∝) = 6(-∝)⁹ - 6(-∝)⁴ - 6

Evaluate

f(-∝) = -∝ - ∝ - 6

So, we have

f(∝) = -∝

This means that

As x ⇒ +∝, f(x) ⇒ +∝ and as x ⇒ -∝, f(x) ⇒ -∝

The equation of the function is given as

f(x) = -3x⁴ - 6x + 4x - 5

f(∝) = -∝ - ∝ - 5

So, we have

f(∝) = -∝

Also, we have

Answer: First divide everything by 3 to make it simpler. Then subtract 12 on both sides to get the equation "x+2y-12 = 0. You can then graph this.

Step-by-step explanation:

1) The area of the picture without the frame will be A.

So the area without frame is 896 square centimeters.

2) If the frame is 2 cm all around then the length and width increase by 4.

So the length becomes 32+4=36cm and the width becomes 28+4=32.

The area of big rectangle which is the frame is A'.

So the area of the frame is 1152 square centimeters.

3) The area of the margin will be the difference of the area of the frame and area of the picture, so it will be A'-A

So the area of the margin is 256 square centimeters.

Answer:

She invested an amount of $3,000 in the first accont and $27,000 in the second account

Explanation:

Here, we want to get the amount invested in each of the accounts

To get this,let us write the simple interest formula

Mathematically, we have this as:

Let the amount invested in the first account be $x, while that of the second account be $y

P represent the amounts invested

R is the rate of investment

T is the time (1 year)

The sum of these two is the $30000 she has to invest

Mathematically, we have this as:

Let us get the interests on each of the accounts

For the first account, we have the interest as:

For the second account, we have the interest as:

The sum of these two is the interest value, which is as follows:

So, we have two equations to solve simultaneously

The two equations are:

We can solve this by substitution

Let us substitute for y

Insert this into the second equation, we have this as:
