What is the difference of the lengths of BD and CE ? Use the value (pie) = 3.14, and round the answer to two decimal places.

lys-0071 [83]

Answer:

1.57 units

Step-by-step explanation:

The formula for arc length is given as:

Arc Length = $\frac{\theta}{360}*2\pi r$

Now,

Arc length of BD = $\frac{45}{360}*2(3.14)(6)=4.71$

Arc length of CE = $\frac{45}{360}*2(3.14)(8)=6.28$

The difference in CE and BD is $6.28-4.71=1.57$

Second answer choice is right.

***** CE falls in the larger circle whose radius is AB + BC = 6+2=8

BD falls in the smaller circle whose radius is AB=6

- 5

Step-by-step explanation:

Probability of a coin toss : (H, T)

With probability of 0.5 each

X : ____100 ____ - 110

P(x) :___ 0.5 ____ 0.5

Expected value ; E(X) = ΣX*p(X)

E(X) = (100 * 0.5) + (-110 * 0.5)

E(X) = 50 - 55

E(X) = - 5

Expected value = - 5
