Suppose the x-axis of a density graph represents someone's age in years. If the area under the density graph from 10 years to 70 years is 0.85, what is the
probability of someone's age being anywhere from 10 years to 70 years?

A. 77%
B. 93%
C. 61%
D. 85%

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

Find the dimensions of the circle. area = 64π in.² r= in.

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
