Population lottery numbers: 56, 42, 19, 8, 24, 13 find the total number of samples of size 4 that can be drawn from this populat
statuscvo [17]

Answer:

The correct answer is there are 15 samples each of size 4 to choose from the population and the population mean is 27.

Step-by-step explanation:

Total number of lottery tickets = 6

Number of samples of size 4 that can be drawn from this population of 6 lottery numbers are = \left[\begin{array}{ccc}6\\4\end{array}\right] = 15.

Now the population mean is given by \frac{1}{n} × ∑ x , where n is the number of lottery tickets and ∑ x  is the sum of the lottery numbers.

Summation of the lottery ticket numbers is 162

Thus the population mean is given by \frac{162}{6} = 27.

I NEED HELP PLSS ITS LIKE 200 POINTS
zysi [14]

Answer:

y=-3/2x+3

Step-by-step explanation:

(0,3) and (2,0) tell us that the y intercept is 3 because at x = 0, y = 3.

This leaves the first and last choice only.

We can calculate the slope by 0-3 and 2-0, so -3/2 is the slope

This is about angles. Please answer someone?
NISA [10]
Actually, this is not about angles.  It's about the length of the sides in a right triangle.

In EVERY right triangle, the squares of the lengths of the short sides add up
to the square of the length of the longest side.  You're in high school math,so
I'm SURE you've heard that in class before ... possibly even just before you
were assigned this problem.

Let's say that again:  The squares of the lengths of the sides that meet at
the  right angle add up to the square of the length of the longest side.  In
the triangle in this particular problem, that means
                                                                             a² + b² = c²

You know the lengths of 'b' and 'c', so you shouldn't have any trouble finding
the length of 'a'.
