Can anyone tell me what number (a) is on this question?

A study shows that the lengths of the careers of professional football players are nearly normally distributed with a mean of 5.2 years and a standard deviation of 1.9 years. (For each answer, enter a number.)

(a) What percent of professional football players have a career of more than 8 years? (Round your answer to one decimal place.)

%

Using technology,

normalcdf(lower = 8,upper = 9999, mean = 5.2, sd = 1.9) =

0.0703

About 7% of professional football players have a career of more than 8 years.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
