Answer:

  10.8 miles

Step-by-step explanation:

The distance between (-3, -4) and (3, 5) can be found using the distance formula.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((3 -(-3))^2 +(5 -(-4))^2) = √(6^2 +9^2) = √117

  d ≈ 10.8

It is about 10.8 miles from the mall to the park.

The____of a circle centered at the origin measures the distance from the origin to any point on the circle.

A set of data has 50 observations. How many classes would you recommend?​
nignag [31]

Answer:

  • 6 classes

Step-by-step explanation:

If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.

<u>We have n = 50 and:</u>

  • 2^5 = 32 < 50
  • 2^6 = 64 > 50

As per above described 2 to k rule, we are taking k = 6.

So 6 classes should be used.
