Answer:
honestly for division of fractions the only sentence you need to know is...
"mine is not to question why, but to invert and multiply"...
fractional division can be done with "an inverse multiplication:
5/6 ÷ 1/6 can be changed to 5/6 * 6/1 = 30/6 = 5
3/5 ÷1/10 can be changed to 3/5 * 10/1 = 30/5 = 6

Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

Given that n = 49, μ = 260 mg/dL, σ = 35 mg/dL
a) For x < 210:

From the normal distribution table, P(x < 210) = P(z < -10) = 0.0001
b) For x > 205:

For x < 215:

P(205 < x < 215) = P(-11 < z < -9) = P(z < -9) - P(z < -11) = 0.0001 - 0.00001 = 0.00009
c) For x < 200:

From the normal distribution table, P(x < 200) = P(z < -12) = 0.00001
d) For x > 222:

From the normal distribution table, P(x > 200) = 1 - P(z < -12) = 1 - 0.0001 = 0.9999
