A wildlife preserve features a crocodile with a documented age of 24 years, believed to be one of the oldest crocodiles in capti
zysi [14]

Answer:

0.0104

Step-by-step explanation:

Given that, the lifespans of crocodiles have an approximately Normal distribution, with a mean of 18 years and a standard deviation of 2.6 years.

So, mean, \mu=18

and standard deviation, \sigma=2.6

The z-score, for any arbitrary life span of  x year, is given by

z=\frac{x-\mu}{\sigma}

By using the given values, we have

z=\frac{x-18}{2.6} \cdots(i)

The z-score for x=24, by using equation (i), is

z=\frac{24-18}{2.6}=\frac{6}{2.6}=2.31

From the table, the area to the left side of z=2.31 =0.98956

But, the proportion of crocodiles have lifespans of at least 24 years

= Area to the right side of the z=2.31

=1- (Area to the left side of the z=2.31)

=1-0.98956

=0.01044

So, the proportion of crocodiles that have lifespans of at least 24 years is 0.0104.

Hence, option (a) is correct.

weqwewe [10]

Answer:

The reflexive property of congruence allow us to say that RST = RST .

Option (C) is correct .

Step-by-step explanation:

Definition of Reflexive Property of congurence

The meaning of  Congruence is  figure has the same size and shape. If you were comparing something to itself, then it definitely have the same size and shape this is called Reflexive Property of congurence .

By using Reflexive property of congurence .

RST = RST

Therefore reflexive property of congruence allow us to say  that RST = RST .

Option (C) is correct .
