Imagine that you are doing an exhaustive study on the children in all of the daycares in your school district. You are particularly interested in how much time children spend in active play on weekends. You find that for this population of 2,431 children, the average number of minutes spent in active play on weekends is μ = 65.87, with a standard deviation of σ = 87.08. You select a random sample of 25 children of daycare age in this same school district. In this sample, you find that the average number of minutes the children spend in active play on weekends is M = 59.28, with a standard deviation of s = 95.79.

The difference between M and mu is due to the sampling error is ______.

Answer:

x=−3 and y=−1

Step-by-step explanation:

Substitute y=4x+11y=4x+11 into 2x-5y=-12x−5y=−1

-18x-55=-1−18x−55=−1

Solve for x in -18x-55=-1−18x−55=−1.

x=-3

Substitute x=-3x=−3 into y=4x+11y=4x+11.

y=-1

Answer:

28

Step-by-step explanation:

2x-5(4x+11)=-1

2x-20x+55=-1

-22x+55=-1

-22x+55-55=-1-55

-22x/-22=-56/-22

x=28

Answer:

360 × 30

= (360 × 3) × 10

= 1080 × 10

= 10800

Step-by-step explanation:

For the first two blanks, we will have to find a pair of factors of 30 that will make this the easiest to solve. Lets pair up all of the factors of 30.

1, 30

2, 15

3, 10

5, 6

So now we have found all of the factors of 30. We can eliminate 1 and 30, since we will just end up with 360 × 30 in the second line. We could use 2 and 15, but we will end up with _____ × 15 in the second line, which would be more difficult to solve for than the other two options. Now, you should use any one of the final two pairs of factors. I would use 3 and 10, since I find it much easier to multiply something by 3 and 10 than 5 and 6.

Lets put 3 in the first blank and 10 in the second blank. We will end up with:

(360 × 3) × 10

Now 360 × 3 would be 1080. So the second line would be:

1080 × 10

1080 × 10 would equal 10800. So the final line and the final blank would be:

10800

So in order, the lines would be:

= (360 × 3) × 10

= 1080 × 10

= 10800

Answer:

the origin

Step-by-step explanation:

A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin.

The distribution of set A is a normal distribution

The data in set A is given as:

1 3 3 2 4 0 4 3 3 5 2

Represent the dataset as a plot, as follows

0

1

2 2

3 3 3 3

4 4

5

Notice that the plot above increase from 0, then reaches a maximum at 3, and then decreases from 3 to 5

This implies that it follows a bell curve.

When a distribution follows a bell curve, such data is a normal distribution.

Hence, the distribution is a normal distribution

Answer:

[tex]\displaystyle y=14\cdot x[/tex]

Step-by-step explanation:

Directly Proportion

It's said that y varies directly proportional as x, if:

[tex]y=k\cdot x[/tex]

Where k is a constant of proportionality.

We know that y=7 when x=1/2.

Using the above condition, we can find the value of k:

[tex]\displaystyle 7=k\cdot \frac{1}{2}[/tex]

Solving for k:

k=14

Thus, the equation is:

Answer:

$675

Step-by-step explanation:

You multiply 15 and 100 answer for that is 1500 then you multiply 21.75 and 100 answer for that is 2175 finally you subtract 1500 from 2175 witch gives you the final answer of 675

Total profit from the sale of 100 shares is equals to $675.

" Profit is the amount of money or revenue which we earned when  selling price of a product is more than its cost price."

Formula used

Profit = Selling price - Cost price

According to the question,

Cost price  of 1 share = $15

Therefore,

Cost price of 100 shares = 15 × 100

                                         = $1500

Selling price of 1 share = $21.75

Selling price of 100 shares = 21.75 ×100

                                            = $2175

Selling price > Cost price

Therefore , Profit

Substitute the value in the formula we get,

Profit = 2175 - 1500

         = $675

Hence, total profit from the sale of 100 shares is equals to $675.

Answer:

negative

Step-by-step explanation:

okay so look at the rise and the run of this line (that is given). slope is defined as rise divided by run. the "rise" is the change in y values, while the "run" is the change in x values. the rise in this problem is -4, as shown on the graph. the run is 3, as also shown there. therefore, the slope is -4/3. the type of slope this is is negative slope because the slope is clearly negative.

Answer:

-4/3

Step-by-step explanation:

(-1 -  3)/(1 - -2)

use the slope formula (y2 - y1)/(x2 - x1)

This is a fraction with a square root.

Fractions:

Are Not Whole (square root cancels this)

Are Rational BUT since this has a square root, it is not.

Are not natural

Are not integers (Whole numbers that ARE NOT fractions)

So basically from what I have learned, square root cancels literally everything.

Slope: 3

y = 3x - 4

Answer:

n=-8

Step-by-step explanation:

6.4n + 10= 4.4n -6

Subtract 4.4n on both sides

You then have 2n+10=-6

Subtract 10 on both sides You then have 2n=-16

Divide both sides by 2

n= -8

Hoped that helped

Answer:  n= -8

Step-by-step explanation:

Get all the n's on one side, all the regular numbers on the other  

Add or subtract from both sides

6.4n -4.4n +10  =  4.4n -4.4n -6   So 4.4n -4.4n = 0, "cancels' on right

2.0n  +10 -10 = -6 -10     10's cancel on the left.  -6-10 .=-16 on right

2n = -16    (.0 is not needed in 2.0)  Divide both sides by 2

n = -8  

Answer:

slope: 4

y-intercept: 2

Step-by-step explanation:

We are given an equation, y = 4x + 2, and we are asked to find the slope and y-intercept of the line. Looking carefully, we can see that the equation is given to us in slope-intercept form.

Slope-intercept form is:

y = mx + b

where m is the slope and b is the by-intercept.

Knowing this, we can find that 4 is the slope of the line and 2 is the y-intercept.

I hope you find my answer and explanation to be helpful. Happy studying.

You can subtract 2y from both sides of the first equation and then plug that (x = 7 -2y) into the second one to get:

14 - 4y  + y = 5 -->

14 - 3y = 5 -->

-3y = -11 -->

y = 11/3 -->

x = 2/3
