Jose is training for a marathon. if he ran 160.2 miles in january, 163.2 miles in february, 157.8 miles in march, and 159 miles in april, how can we use clustering to estimate how far he ran in those 6 months?

I think it's 960.

Step-by-step explanation:

Add up all of the numbers:

(160.2+163.2+157.8+159) = 640.2

Find the average by diving 640.2 by how many numbers there are:

640.2 ÷ 4 = 160.05

Round that average^^:

160.05 >>> 160

Multiply by how many numbers there will be:

In this case, your job is to estimate how far Jose ran in 6 months, not just those 4. So instead of multiplying the average (160) by 4, you'd multiply it by 6.

160 x 6= 960

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
