If you had a right triangle with legs measuring 40 yards and 100 yards long,
tia_tia [17]

9514 1404 393

Answer:

  (c) 108 yd

Step-by-step explanation:

For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...

  c² = a² +b²

Solving for c, we have ...

  c = √(a² +b²)

  c = √(40² +100²) = √(1600 +10000) = √11600

  c ≈ 107.70 . . . . yards

The length of the hypotenuse is about 108 yards.

What is the margin of error for a sample statistic for a population with a standard deviation of 7.75?
3241004551 [841]

Answer:

Margin of Error  = 1.96 \times 7.75 = 15.19

Step-by-step explanation:

i) Margin of Error of a population with a standard deviation of 7.75?

ii) Let us assume a two tailed test with a 95% confidence interval

iii) Z_{\frac{\alpha }{2} }  = Z_{\frac{\ 0.05 }{2} } = Z_{0.025} = 1.96

iv) therefore Margin of Error  = 1.96 \times 7.75 = 15.19
