Here, we are given;

P(A)=0.6

P(B)=0.42

P(B/A)=0.63

We have to find;

Now,

This is the formula for finding conditional probability.

From here,we can see that we have values of P(B/A) and P(A) and we can easily find P(Aand B) from here.

Since P(A)>0 so we can use this formula.

Therefore,

The interest for the first payment is $30.00

Interest is how much is paid for the use of money.

Therefore, you  take a $4,500 loan to pay for trip to the Amazon rainforest to photograph wild animals.

The  loan's interest rate is 8% for 1 year.

Therefore, the interest for the first payment can be calculated as follows:

Interest for the first payment = 8% of 4500 × 1 / 12

Interest for the first payment = 8 / 100 × 4500 × 1 / 12

Interest for the first payment = 8 × 45 × 1 / 12

Interest for the first payment = 360 / 12

Interest for the first payment = $30

Therefore,

interest = $30

Answer:

y = 7

eight grade math comes back to haunt me

Using the given information, the fraction is 3/8

From the question, we are to determine the fraction

Let the numerator of the fraction be x and the denominator be y

From the given information,

"if the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2, the result is 2"

That is,

4x/(y -2) = 2

and

" If the numerator of the fraction is increased by 15 and 2 is subtracted from the double of the denominator, the result is 9/7"

That is,

(x + 15)/(2y - 2) = 9/7

From the first equation,

4x/(y -2) = 2

4x = 2(y-2)

4x = 2y - 4

4x + 4 = 2y

y = 2x + 2 ----------- (3)

From the second equation,

(x + 15)/(2y - 2) = 9/7

7(x + 15) = 9(2y - 2)

7x + 105 = 18y - 18

Substitute equation (3)

7x + 105 = 18(2x + 2) - 18

7x + 105 = 36x + 36 - 18

105 - 36 + 18 = 36x - 7x

87 = 29x

x = 87/29

x = 3

Substitute the value of x into equation (3)

y = 2x + 2

y = 2(3) + 2

y = 6 + 2

y = 8

Thus, the number is 3/8

Answer:

Step-by-step explanation:

3=1/3^27

Step-by-step explanation:

3 is the answer , you can do it with a calculator

We know that the equation of a line is given by

y = mx + b, where m and b are numbers:

m is the slope of the line and b is the y intercept.

In this case we have the equation:

6 - 2y = - 6

We clear y so we can identify m and b

6 - 2y = -6​

6 = -6​ + 2y

6 + 6​ = 2y

12 = 2y

12/2 = y

6 = y

In this case

y = 6

Then m=0 and b = 6

Answer:

96

Step-by-step explanation:

If Y is directly proportional (or in this case varies directly) then whatever you do to one value you do to the other.

So in this case, when Y = 8 and X = 4 that means that Y is double of X (cause 8 is double 4).

So when X = 48 all you need to do is double X which will give you 96.

The equation have infinitely many solution when n is equal to -15.41.

A linear equation in one variable is an equation which has a maximum of one variable of order 1. It is of the form ax + b = 0, where x is the variable. This equation has only one solution.

Given equation is;

24( mx + n ) = 3x + 17

where; m and n are real numbers.

Part 1.  If m = 14 and n = 13 then

Putting the value of m and n in the equation we get;

= 24( 14.x + 13 ) = 3x + 17

=  336x + 312 = 3x + 17

=  336x - 3x = 17- 312

=  333x = -295

x = 0.886

Hence,  x = 0.886  the equation having one solution .

part 2.  if m = 18 then to find n .

put m = 18 in the given equation;

= 24(18.(0.886) + n ) = 3(0.886) + 17

= 24(15.94) + 24n = 2.658 + 17

= 382.56 + 24n = 19.658

= 24n = 19.658 - 382.56

n = -15.41

The complete question is;

PART A: Rosie writes the equation 24(mx+n)=3x+17, where m and n are real numbers.

If m=14 and n=13, does the equation have one solution, infinitely many solutions, or no solutions? Explain your answer.

A. P( 2∪3∪6 ) = 1/2

B. P( 1∪2∪3∪4∪5 ) = 9/16

The probability of an occurrence e can be written as P (e), and its equation is as follows:

P (e) = Number of favorable outcomes / Total number of outcomes

This can only be used with a straightforward event.

The probability will also be influenced by other factors, whether they are imposed or a result of the event's inherent characteristics.

Using a six-sided die,

A) First, in order to gather as much information as possible from the question, we concentrate on the probabilities provided P(1∪4∪5)=1/2 and P(2∪3∪5)=1/2 and we need to use P(5)=7/16.

It's crucial to remember that while using a dice, receiving two values on the same roll is impossible. Due to this and the likelihood of certain circumstances:

P(1∪4∪5) = P(1) + P(4) + P(5) - P(1∩4)(= 0) - P(4∩5)(= 0) - P(1∩5)(= 0) + P(1∩4∩5)(= 0)

P(1∪4∪5)=P(1) + P(4) + P(5)

1/2 = P(1) + P(4) + 7/16

P(1)+P(4)=1/16

If we do the same with P(2∪3∪5), we get:

P(2) + P(3) = 1/16

Now that we have this new knowledge, we can determine P(6):

P(6) = 1 - P(1∪2∪3∪4∪5)

P(6) = 1 - [P(1) + P(2) + P(3) + P(4) + P(5)] -- (There is no chance that two of these will occur simultaneously.)

P(6) = 1 - (1/16 + 1/16 + 7/16)

P(6) = 1 - 9/16

P(6) = 7/16

And with it, we can find P(2∪3∪6):

P(2∪3∪6) = P(2) + P(3) + P(6)

P(2∪3∪6) = 1/16 + 7/16

P(2∪3∪6) = 8/16 = 1/2

B) Keep in mind that the probability you need to know if you wish to roll anything other than a 6 is P(1∪2∪3∪4∪5)" but we found that in part A

P(1∪2∪3∪4∪5) = 9/16

Uniform line movement.

The uniform rectilinear movement is the movement that maintains a variation of the distance with respect to time always constant, since the acceleration is zero.

If we know that Wilson travels 53.7 miles in 1.6 hours, we determine the average speed from the following equation:

Speed = distance / time

Speed = 53.7 miles / 1.6 hours

Speed = 33.5625 miles/hour

V = 33.6 miles/hour

The average speed that Wilson travels is: V = 33.6 miles/hour.

The average rate for the entire walk of hiker is 3.75 miles per hour by the concept of average speed.

The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. An object's average speed during a certain period of time is equal to its distance traveled over that period divided by its duration. Speed and velocity are distinct concepts.

The whole distance traveled divided by the total time results in the average rate for the entire walk, expressed in miles per hour.

Given that:

Distance A = 12.8 miles

Distance B = 17.2 miles

Total distance = Distance A + Distance B

Total distance= 12.8 + 17.2

Total distance= 30 miles

Time A = 9:00 a.m. to noon = 3 hours

Time B = 1:00 p.m. to 6:00 p.m. = 5 hours

Total time = Time A + Time B

Total time= 3 + 5

Total time= 8 hours

Average rate = Total distance/Total time

Average rate= 30 miles/8 hours

Average rate= 3.75 miles per hour

Therefore, the average rate for the entire walk of hiker is 3.75 miles per hour.

At time 1.75 seconds the ball is in the 51 feet high.

What is substitution method?

Find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The height of the football could be describe by the model,

h = - 16t² + 56t + 2   ..... (i)

Where, h describes the height of the ball in feet.

and t is the time in seconds after the ball was kicked.

Now,

At height 51 feet, the time is calculated as;

Substitute h = 51 in equation (i), we get;

h = - 16t² + 56t + 2  

51 = - 16t² + 56t + 2  

16t² - 56t - 2 + 51 = 0

16t² - 56t + 49 = 0

Solve for t by using quadratic formula;

t = - (-56) ± √(-56)² - 4 × 16 × 49 / 2 × 16

t = 56 ± √3,136 - 3,136 / 32

t = 56 ± 0 / 32

t = 56 / 32

t = 1.75 seconds

Thus, At time 1.75 seconds the ball is in the 51 feet high.

Also the number of burritos sold= 42.

So the total amount earned on selling these burritos= 42× 6 = $ 252

And as it is given that total money she needs to earn is $ 330 .

so required money= $ 330- $ 252

=$ 78
