Answer:

The complement of spinning any number less than 3, is spinning a number equal to or greater than 3.

Explanation:

The complement of a subset is the subset of elements that are not in the given subset.

You must know which numbers the spinner has.

Assuming the spinner has the numbers 1, 2, 3, 4, the complement of spinning any number less than 3, is spinning a number that is not less than 3.

Then, that is spinning a number that is equal to or greater than 3.

The numbers that are equal to or greater than four, for a spinner that has the numbers 1, 2, 3, and 4 are 3 and 4.

Thus, the complement of spinning any number less than 3 is spinning a three or a four.

The correlation analysis assumes that the measurements have a bivariate normal distribution in the population. Select all of the

RoseWind [281]

Answer:

A. True

B. True

C. False

D. False

E. False

F. False

G. True

Step-by-step explanation:

Select all of the features that define a bivariate normal distribution.

(this means that we select only those that are properties of the bivariate normal distribution)

A. Bell-shaped probability distribution in two dimensions rather than one

TRUE because any combination of the two is still normal Z(x,y)=aX+bY

B. A relationship between X and Y that is not linear

TRUE The contours of the distribution are ellipses.

C. The presence of outliers

FALSE possible, but not always.

D. Either X or Y has a decidedly skewed distribution

FALSE normal distributions are symmetric

E. A relationship between X and Y that is linear

FALSE see answer to B

F. A cloud of points that is funnel shaped (wider at one end than the other)

FALSE normal distributions are symmetric

G. The frequency distributions of X andY separately are normal

TRUE For example, in Z(x,y)=aX+bY, putting a or b=0 means that X and Y separately are normal.

If the question is how many students are girls, than it's ten(10).

Use the remainder theorem to find P(−2) for P(x) = 2x^4+2x^3−2x-4

Law Incorporation [45]

Answer:P(2) = 2(2)³ - 2(2)²- 3

= 16 - 8 - 3

= 5

Remainder or value of P(2) = 5

Quotient = (2x³- 2x² - 3)/ x-2 = 2x² + 2x + 4

Juno is taking a taxi. The table represents a linear function and shows the amount she owed after various numbers of miles trave

Gennadij [26K]

(B) - Yes, because the amount owed changes by 2.25 every time the miles change by 1.

Starting at 1 mile the price is 2.5 dollars.

Mile 2 is 4.75 dollars. What is the difference between 4.75 and 2.5? 2.25

Mile 3 is 7 dollars. What is the difference between 7 and 4.75? 2.25

Mile 4 is 9.25 dollars. What is the difference between 9.25 and 7? 2.25

Mule 5 is 11.5 dollars. What is the difference between 11.5 and 9.25? 2.25

The change is always 2.25 dollars.

The change is 2.25 dollars per mile.

One way to solve for this is (11.5 - 2.5)/(5-1)=2.25

This is (y2-y1)/(x2-x1). By picking 2 points, (x1,y1) and (x2,y2) you can solve for the slope (rate of change) between them.
