Census data from a city of 80,000 residents produced the income distribution shown here:
110
60
Income (thousand dollars)
Suppose that we were to take random samples of 5 residents from this population and calculate the sample
mean income of the residents in each sample.
What will be the shape of the sampling distribution of the sample mean?

Answers

Answer 1

Answer:

Skewed to the right

Look at dis \/

The shape of the sampling distribution of the sample mean will match the shape of the parent population since the sample size is small (n=5<30), although it will be closer to normal than the parent population is.

Combine and simplify the following radical expression.
(2^3 square root 12) (3^3 square root 2)

Answers

432[tex]\sqrt{6}[/tex]

Step-by-step explanation:

Given: ([tex]2^{3}[/tex][tex]\sqrt{12}[/tex])([tex]3^{3}[/tex][tex]\sqrt{2}[/tex])

 = (8[tex]\sqrt{4*3}[/tex])(27[tex]\sqrt{2}[/tex])

 = (8*2[tex]\sqrt{3}[/tex])(27[tex]\sqrt{2}[/tex])

 = (16[tex]\sqrt{3}[/tex])(27[tex]\sqrt{2}[/tex])

So that;

16 x 27 x [tex]\sqrt{3}[/tex] x [tex]\sqrt{2}[/tex]

 = 432[tex]\sqrt{6}[/tex]

Thus the radical expression given can be simplified as 432[tex]\sqrt{6}[/tex]

Why or why not?

Answers

Answer:

No.

Step-by-step explanation:

Well at first glance it might seem so but there are two points particularly that can tell you that these points cannot be within a function.

The points (3,2) and (3,-2) will yield an undefined slope (a straight vertical line). There is no possibility that the other points can be in this line (as their y - values are different) and there is no possibilty that this is a function at all according to the vertical line test (the test is that if you draw a vertical line that there shouldn't be more than one point on it).

How many sides does a polygon have if the sum of its interior angle measures is
7380°?

Answers

43

if so, use the formula for sum of interior angles in a polygon to solve. 7380 = (n - 2)(180), where n is the number of sides. The number of sides of the polygon is 43.

There are 43 sides in a polygon,  if the sum of its interior angle measures is 7380°.

What is Polygon?

A Polygon is a closed figure made up of line segments (not curves) in a two-dimensional plane.

We have to find the number of sides in a polygon.

The sum of its interior angle measures is 7380°

The sum of the interior angles of a polygon can be calculated using the formula S = (n - 2) x 180°

where n is the number of sides of the polygon

7380 = (n-2)×180

We have to solve for n

Divide both sides by 180

7380/180=n-2

41=n-2

Add 2 on both sides

43 = n

Hence, there are 43 sides in a polygon,  if the sum of its interior angle measures is 7380°.

The sides of a quadrilateral always add up to 360°.

Missing angle = 360-115-97-68 = 80°

Answer:

D. 80°

Step-by-step explanation:

A quadrilateral always add up to 360°

To find the missing value we first have to add the given number up:

115 + 97 + 68 = 280°

Now we minus our value from 360° :

360° - 280° = 80°
