Mathematics
1 answer:
sergiy2304 [10]2 years ago
4 0

Answer:

30  

Step-by-step explanation:

Each digit in a whole number has a place value, based on its position from the decimal point.

The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.  

Numbers to the left of the decimal point increase in place value in the order: ones, tens, hundreds, etc.

The value of a digit is the digit multiplied by its place value.

So, the digit 3 in 731.8 has a value of 30.

A collection of numerical information, such as the scores on a test, is referred to as simple random sampling.True / False.
Nimfa-mama [501]

Answer:

False. See explanation below.

Step-by-step explanation:

False

A simple random sample "is a subset of a statistical population in which each member of the subset has an equal probability of being chosen"

In other words that means in order to apply a random sampling we need to ensure that we have the same probability of inclusion for every possible element of the population of interest.

And for this case a collection of any numerical information is not referred as random sampling since we don't know if these scores are representative of the population of interest.

And we don't know if this information is obtained using any sampling frame or sampling methodology.

Please help it’s the last question
Mrac [35]

Answer:

y= -\frac{5}{6}x - 1 is the answer

Step-by-step explanation:

Equation of the line: y = 6/5x + 1

                        = 5y = 6x + 5

                        = 6x - 5y + 5

Equation of the perpendicular line: bx - ay + k = 0

                                                       = -5x -6y + k = 0

Equation passes through (6,-6),

-5(6) -6(-6) + k = 0

-30 + 36 + k = 0

6 + k = 0

k = -6

Substituting,

-5x -6y + k = 0

-5x -6y -6 = 0

-6y = 5x + 6

y= -\frac{5}{6}x - 1 (Slope-Intercept form)

How do you find the exterior angle of a polygon?
trasher [3.6K]

The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.

The measure of each interior angle of an equiangular n-gon is.

If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.
