A sail is in the form of a right triangle that is three times as high as it is wide. The sail is made from 24 square meters of material. WHAT IS ITS HEIGHT??? Remember...a=1/2bh

Answers

The area of a triangle as stated above is calculated through the equation, A = ab/2 where a and b are altitude and base, respectively. From the condition given above, a = 3b. The area is therefore,
                              A = 24 m² = (3b)(b) / 2
The value of b is equal to 4 which gives height equal to 12 m.

Answer:

0.9773,10.57%,,51.31, 56.69

Step-by-step explanation:

Given that in a certain population of herring, Pomolobus Aestivalis, the lengths of the individual fish are normally distributed. The mean length of a fish is 54 mm and the standard deviation is 4mm.

Let X represent the length of fish caught

X is N(54, 4)

a.)  the probability that the first fish capture is less than 62mm long

b.)  percentage of the fish are longer than 59 mm

=59)\\=100(0.10565)\\=10.57%" alt="100*P(X>59)\\=100(0.10565)\\=10.57%" align="absmiddle" class="latex-formula">%

c.)  the 25th Percentile value

=51.31

d) 75th percentile value

=56.69

d.) What is the 70th Percentile value?
