A student is initially outside. He is given the choice with a probability of 0.4 of going to the playground, 0.3 of shopping in the mall and 0.3 of returning home. If he is in the playground, he takes 2 hrs of time and then decides to stay in the playground again or return back home. (he can continue to decide to stay in playground like a recursive process) Similarly, If he is in the mall, he takes 3 hrs of time and then decides to stay in the mall again or return back home. (he can continue to decide to stay in mall like a recursive process) For all cases, it takes 1 hr to return home. what is the expected hours the student was outside home?

We can conclude that Jeffry will reach his home in the time of 9 hours.

So, the time taken by Jeffrey to get home:

Now calculate time as follows:

Rounding off: 9 hours

Therefore, we can conclude that Jeffry will reach his home in the time of 9 hours.

Part A: The vertex, domain, and range of the function g(x) = |x-5|  is

( 5, 0 ), ( - ∞ , ∞ ) and [0, ∞ ).

Part B: The function f(x) = |x| is vertically shifted by 3 units to get the function h(x) = |x| + 3. The y - coordinate of the vertex is shifted by 3 units.

In Part A:

The given function is;

g(x) = | x - 5 |.

Now, The x - coordinate of the vertex will be:

x - 5 = 0

x = 5

Therefore, the y- coordinate of the vertex will be:

y = g(x) = | x - 5 |

y = g(7) = | 5 - 5|

y = 0

So, The vertex of the absolute function is ( 5, 0 ).

Since, All real numbers fall under the expression's domain, with the exception of cases where it is undefined. In this case, the phrase is defined even if there is no real number.

Hence, In Interval Notation the domain is;

⇒ ( - ∞ , ∞ )

And, The set of all legitimate y values is the range.

Hence, In Interval Notation the range is:

⇒ [0, ∞ )

Now, In Part B:

Function h(x) = |x| + 3 is the transformed version of the parent function

f(x) = |x|.

For the parent function f(x) = |x|, the vertex is ( 0, 0).

Since, The range of an absolute function in the form c( | ax + b | ) + k is

f(x) ≥ k.

Therefore, The range of the function f(x) = |x| is f(x) ≥ 0 and in interval notation is [ 0, ∞ ).

For the transformed function h(x) = |x| + 3.

The vertex of the function is ( 0, 3 ).

The range of function is h(x) ≥ 3 and in interval notation is [3, ∞ ).

Hence, the y coordinate of the vertex is transformed by 3 from f (x) to h(x).

So, Part A: The vertex, domain, and range of the function g(x) = |x-7|  is  

( 5, 0 ), ( - ∞ , ∞ ) and [0, ∞ ).

Part B: The function f(x) = |x| is vertically shifted by 2 units to get the function h(x) = |x| + 3. The y coordinate of the vertex is shifted by 3 units.

The number of children's tickets sold is 13750.

Let the number of children be x and the number of adults be y.

The total number of attendance at the amusement park is 25,000.

So we have an equation

x + y = 25000 ......(i)

The cost for children is $15 and the cost for adults is $35, and the total money earned by the park is $600,000.

So we have another equation,

15x + 35y = 600,000

3x + 7y = 120,000 ......(ii)

Multiplying equation (i) with 3 we get

3x + 3y = 75000

3x + 7y = 120,000

Now subtract both the equation we have,

4y = 45000

y = 11250

Now put the value of y in equation (i) we get

x + 11250 = 25000

x = 13750

Where x is the number of children's tickets sold.

Therefore the number of children's tickets sold is 13750.

Answer:

The answer should be x=2.6

Step-by-step explanation:

9x-9=3x+7

-first you should move the numbers so you can get all your x values on one side and all your regular numbers on the other like this

9x-3x=7+9

-What i basically did was i passed the 3x from the right side to the left side of the equation, since in adding the 3x originaly, when i pass it to the left side itll be subtracting. then i passed my -9 to the right side of my equation, since i was subtracting originaly ill have to now switch it to adding

-after you do this you are going to want to want to combine like terms

6x=16

-then you are going to want to devide on both sides so you can get x alone

x=2.6

The test statistic for the anova is an F test and it is said to be positively skewed which would be to the right of the F test statistic.

This is the term that is used to refer to the short form of the term that says analysis of variance.

The ANOVA is used to show the variation that would be in existence of a group of observations.

The F test is known to be positively skewed at all times. So we would have it that the P value would have to be to the right and not to the left in the ANOVA hypothesis.

Answer:

For the given system of equations 4x + 6y=24 and 2x + 3y=8, there is no solution exists.

For the given system of equation,

4x + 6y =24  ......eq 1

and 2x + 3y = 8 ..... eq2

use elimination method.

Multiply eq 2 with 2 and subtract from eq 1.

0 = 16

But 0 ≠ 16, the system of equation becomes untrue.

As, the values o f the variables x and y are getting cancelled. So, the there is no solution existed for the given system.

Also,the ratio of 4x/2x = 2 and 6y/3y = 2 is same thus, no solution is possible for the system.

Now, when the we triple each side of the first equation 4x+6y=24, we have 12x+18y=72.

The new system 12x+18y=72 and 2x+3y=8

Then, also 12x/2x = 6 and 18y/3y = 6 is also same. Then, also the system of equation does not have any solution of the system.

Thus, the system of equation does not have any solution.

The first equation is increasing at highest rate.

Which function has highest increasing rate?

We can know which function has the highest rate of increase by looking at its slope. The function with the highest slope will have the highest rate.

In equation first m = 2 and is highest among every slope.

12x - 6y = -24

-6y = -12x -24

y = 2x +4

m = 2 (increasing)

In second equation m = 1

m = (-4 + 5)/(2-1) = 1

for a straight line function , the slope is given by

m = ( y₂ -y₁)/(x₂-x₁)

m = ( -3 -3)/(2- (-1)) = -6 /3 = -2

P=Present amount=$4739

r=interest rate = 0.051

n=number of compounding periods =12
