P is the centroid of triangle ABC. AE = 21, CD = 14, and BF = 11. What is the length of AP?
Rus_ich [418]

Answer

AP=14

Step by Step Explanation

1) Due to the Centroids Theorem we can say that:

AP=2/3AE

AP=2/3*21

∴AP=14

2) Finally, AE =AP+AE

21=14+7 ⇒21=21 True

AP =2PE verifies the Theorem too.

So, the size is 14 .

AP=14\:u

Current research indicates that the distribution of the life expectancies of a certain protozoan is normal with a mean of 43 day
Sunny_sXe [5.5K]

Answer: 0.0688

Step-by-step explanation:

Given : Current research indicates that the distribution of the life expectancies of a certain protozoan is normal with a mean of 43 days and a standard deviation of 10.1 days.

i.e. \mu=43  and \sigma= 10.1

Let x represents the  life expectancies of a certain protozoan.

Sample size : n= 25

The probability that a simple random sample of 25 protozoa will have a mean life expectancy of 46 or more days. :-

P(x\geq46)=1-P(x

=1-0.9312=0.0688   [using z-value table]

Hence, the required probability = 0.0688
