Can you wiggle your ears? Use the students in your statistics class (or a group of friends) to estimate the percentage of people

who can wiggle their ears. How can your result be thought of as an estimate for the probability that a person chosen at random can wiggle his or her ears? Comment: National statistics indicate that about 13% of Americans can wiggle their ears (Source: Bernice Kanner, Are You Normal?, St. Martin's Press, New York). The resulting relative frequency can be used as an estimate of the true probability of all Americans who can wiggle their ears. The resulting relative frequency can be used as an estimate of the true probability of all Americans who cannot wiggle their ears. The resulting relative frequency is the true probability of all Americans who can wiggle their ears. The resulting relative frequency cannot be used as an estimate of the true probability of all Americans who can wiggle their ears.

Factorize -pq -pr +mq +mr​
trapecia [35]

Answer:

(q + r) (m - p)

Explanation:

  • -pq - pr + mq + mr​
  • Factor out common term 'p'

= -p(q + r) + mq + mr

  • Factor out common term 'm'

= -p(q + r) + m(q + r)

  • Factor out common term '(q + r)'

= (q + r) (-p + m)

  • (q + r) (m - p)

- PNW

Midpoints of segment with endpoints. (-4,2) and (2,4)
sashaice [31]

Well! See ,If the endpoints are (x1,y1) & (x2,y2) then mid-point is given by (x1+x2)/2,

(y1+y2)/2

Here in this question endpoints given for the line segment are (-4,2) , (2,4) so we have to find mid-point for x and y co-ordinates by applying above rule.

So, the mid-point we get is (-4+2)/2 , (2+4)/2.

i.e. (-1,3) which lies in 2nd Co-ordinate!

Hope it helps!!

Suppose that events a and b are mutually exclusive with p(a) = ½ and p(b) = ⅓.
irina1246 [14]
No, a & b are not independent if they're mutually exclusive.

Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.
