X in an example​ of stochastic variable.

What is meant by stochastic variables?

Typically, a random (or stochastic) variable is defined as a variable that can assume more than one value due to chance.

The correct answers are: (a) stochastic variable: By stochastic variable we mean a variable (here X: the weight of students) whose values are subject to variation due to chance.

Here since X is the weight of the children sampled, hence X will vary along with change in the sampling units which gets selected by chance.

Hence X for a sample A and X value for a different sample B will be different. So the values of X vary due to chance ( chance takes part in the selecton of the sample). So X is a stochastic variable.

Root 40 to the nearest 10 is 6.3

The root of a number in math is a number that when multiplied by itself produces the original number. For example, the square root of 49 is 7 because 7×7=49.

Rounding off to the nearest 10 means that we wish to round off the last two digits of a number, that is up to the tens place of a number.

We have been given that 40 is the number whose root we have to round off so here are step-by-step instructions for how to get the square root of 40 to the nearest tenth:

Step 1: Calculate. We calculate the square root of 40 to be: √40 = 6.32455532033676.

Step 2: Reduce. 6.32.

Step 3: Round. Round 6.32 so you only have one digit after the decimal point to get the answer: 6.3.

So therefore the nearest 10 of root 40 is 6.3

By taking the difference between the total cost of the condo and the amount that he already paid, we conclude that Joe owes a total of $160,000 for the condo.

To find how much he owes on the condo, we need to find the difference between the total cost of the condo, which is $200,000, and the amount that he already paid, which is $40,000.

(Remember that difference means a subtraction)

It gives.

$200,000 - $40,000 = $160,000

In this way, we conclude that Joe owes a total of $160,000 for the condo.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Let y be the total amount and x be the number of miles.

Samir can rent a moving truck from Company A for $35 plus $0.50 per mile. Then the equation will be

Answer: $48 for 9 rides

$(30+2r) for r rides

Step-by-step explanation:

r=rides. t=total money spent

t=30+2r

t=30+2(9)

t=30+18

t=$48 for 9 rides

t=$(30+2r) for r rides

Mason has to pay $48 as total if he goes on 9 rides and he would have to pay a total of $30 + $2r if goes on r rides.

If Mason goes on 9 rides, we can calculate his total cost using the given information.

Admission cost: $30

Cost per ride: $2

Number of rides: 9

Total cost = Admission cost + (Number of rides × Cost per ride)

Total cost = $30 + (9 × $2)

Total cost = $30 + $18

Total cost = $48

Now, let's calculate how much he would have to pay if he goes on "r" rides.

Total cost = Admission cost + (Number of rides × Cost per ride)

Total cost = $30 + (r × $2)

Total cost = $30 + $2r

So, if Mason goes on 9 rides, he would have to pay a total of $48 and  if Mason goes on "r" rides, he would have to pay a total of $30 + $2r.

Solving a linear equation, we can see that each box has 15 jars.

We know that Neve has 12 full boxes of jars of slime, and 7 jars of slime, then if each box has N jars, the total number of jars that Neve has is given by the linear equation:

12*N + 7

Now we know that Neve has 187 jars in total, then we can write:

12*N + 7 = 187

We want to find the value of N, which is the number of jars in each box, so we need to solve the linear equation:

12*N + 7 = 187

12*N = 187 - 7

12*N = 180

N = 180/12 = 15

We conclude that there are 15 jars in each full box.

First do 7/100 to convert the percent to a decimal, you will get 0.07, now to get 7% of $5136 multiply .07 and 5136 to get 359.52. So she had to pay $359.52 in GST

The range in which the usage vary is from 682.77  kilowatt-hours to 2867.11  kilowatt-hours.

Given the charge of electricity charge is 6.434 cents  per​ kilowatt-hour.

Fixed customer charge = ​$7.81

Bill range = $51.74 to ​$​192.28

Since every value is in $ , we will first convert cents to dollar

per​ kilowatt-hour charge will be $6.434/100    ( as $1 = 100 cents )

per​ kilowatt-hour charge = $ 0.06434    …(1)

Lets us first find the lower range of usage

Last year's lowest bill was $51.74 (including the customer charge)

So last year lowest bill = $51.74-$7.81  = $43.93   …(2)

We know that (per KWh charge)x(no. of KWh used)=Total bill. …(3)

Substituting the values from (1) & (2) we get

(0.06434)x(no. of KWh used)=$43.93

no. of KWh used=[tex]\frac{43.93}{0.06434} = 682.77 KWh[/tex]

Similarly we will solve for maximum KWh used

Lets us find the maximum range of usage

Last year's highest bill was $192.28 (including the customer charge)

So last year highest bill = $192.28-$7.81  = $184.47   …(4)

Substituting the value of (1) & (4) in (3) we get

(0.06434)x(no. of KWh used)=$184.47

no. of KWh used=[tex]\frac{184.47}{0.06434} =2867.11 KWh[/tex]

Therefore ,  the The range in which the usage vary is from 682.77 kilowatt-hours to 2867.11  kilowatt-hours.
