Screen measures 30 cm wide n 22 cm high what is the diagonal measure of the screen

1 answer:

8 0

I think you'd use the pythagoran theorem for this (a squared + b squared = c squared). So 30 squared plus 22 squared equals the diagonal measure squared. This is 900 + 484 = c squared. That's 1384. The square root of that is 37.

A survey of students' favorite sports was taken from a random sample of

White raven [17]

Answer:

129

Step-by-step explanation:

Considering the survey to be representative, you can simply multiply the share of students p preferring “Track & Field” with the whole school population at the same time to estimate the number of such students in the whole school.

First we need to find the relative share p of such answers in the study by dividing it by the sum of answers, assuming that the table is complete for that random sample:

p = 4/(8 + 5 + 4) = 4/17

Then for the whole school we get 550 p ≈ 129.4

Paul [167]

First term: a(1) = 4; common ratio: r = 2

Then:

a(n) = 4(2)^(n-1)

Check: Predict the 4th term using this formula:

a(4) = 4(2)^3 = 4(8) = 32 (correct)
