The median is 65
$60 + 70 = 130 \\ 130 \div 2 = 65$
the 2nd and third quartile is 65
$50 + 60 + 70 + 80 = 260 \\ 260 \div 4 = 65$

#19 The distance between the points (4, 1) and (9, 1) is

kirill115 [55]

Hello!

Given the two points, $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ , and to find the distance between these two points is found by using the formula:

$d = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}$

$(x_{1}, y_{1})$ is assigned to one the points, in this case, is (4, 1).

$(x_{2}, y_{2})$ is assigned to other point, which is (9, 1).

Then, plug in these values into the formula and solve.

$d = \sqrt{(9-4)^{2}-(1-1)^{2}}$

$d = \sqrt{5^{2}-0^{2}}$

$d = \sqrt{25}$

$d = 5$

Therefore, the distance between the two points is 5.

What is the sign of the product (3)(-3)(-2)(4)? (5 points) Select one: a. Positive, because the products (3)(-3) and (-2)(4) are

Gnesinka [82]

Answer: a. Positive, because the products (3)(-3) and (-2)(4) are negative, and the product of two negative numbers is positive

Step-by-step explanation: It is also possible to rearrange the factors.

(3)(4) = 12 a positive number.

(-3)(-2) = 6, a positive number. Again "a negative times a negative is a positive" --Jaime Escalante, Stand and Deliver

Now you have two positive numbers: 12×6 = 72

The product is positive either way.
