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.

a.) what is the probability that the first fish capture is less than 62mm long?
b.) what percentage of the fish are longer than 59 mm?
c.) what is the 25th percentile value?
d.) what is the 70th percentile value?

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

=%

c.)  the 25th Percentile value

=51.31

d) 75th percentile value

=56.69

d.) What is the 70th Percentile value?

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
