Answer: B. 95.0

Step-by-step explanation:

In statistics , the famous empirical rule says that " if the data is normally distributed then 68% of the observations will be contained within \pm1 standard deviations from the arithmetic mean, 95% of the observations will be contained within \pm2 standard deviations from the arithmetic mean and 99.7% of the observations will be contained within \pm3 standard deviations from the arithmetic mean".

Hence, B is the correct answer.

Prove that the sum of two odd numbers is an even number
Maru [420]
Let a and b be odd number.
Because they are odd, by definition:
a = 2n + 1 
b = 2m + 1
If we add them up:
a + b = 2n + 1 + 2m + 1
         = 2n + 2m + 2
         = 2(n + m + 2)
         = 2k where k = n + m + 2

therefore a + b is always even.

ABCD is a parallelogram. Find the measure of ZB.
Korolek [52]

Answer:

121°

Step-by-step explanation:

<B = 9x - 5°

<D = 10x - 19°

<B = <D ( being opposite angles of parallelogram)

9x - 5° = 10x - 19°

10x - 9x = 19° - 5°

x = 14°

Now

<B = 9x - 5°

= 9 * 14° - 5

= 121°
