Convert 36 4/9 to an improper fraction. Use this rule: a b/c = ac + b/c

-36 × 9 + 4/9 - (-10 2/9) - 18 2/9

Simplify 36 × 9 to 324

- 324 + 4/9 - (-10 2/9) - 18 2/9

Simplify 324 + 4 to 328

- 328/9 - (-10 2/9) - 18 2/9

Convert 10 2/9 to an improper fraction. Use this rule: a b/c = ac + b/c.

-328/9 - (- 10 × 9 + 2/9) - 18 2/9

Simplify 10 × 9 to 90

-328/9 - (- 90 + 2/9) - 18 2/9

Simplify 90 + 2 to 92

- 328/9 - (-92/9) - 18 2/9

Convert 18 2/9 to an improper fraction. Use this rule: a b/c = ac + b/c.

-328/9 - (- 92/9) - 18 × 9 + 2/9

Simplify 18 × 9 to 162

-328/9 - (- 92/2) - 162 + 2/9

Simplify 162 + 2 to 164

-328/9 - (- 92/9) - 164/9

Simplify brackets

-328/9 + 92/9 - 164/9

Join the denominators

-328 + 92 - 164/9

Simplify

-400/9

Convert to a mixed fraction

-44\frac{4}{9}

If students’ scores were normally distributed and the mean was 200 with a standard deviation of 40, then what is the probability
Sonja [21]

Answer:

  84%

Step-by-step explanation:

The empirical rule tells you that 68% of the standard normal distribution is within 1 standard deviation of the mean. The distribution is symmetrical, so the amount in the lower tail is (1 -68%)/2 = 16%.

Since the number you're interested in, 240, is one standard deviation above the mean (200 +40), the percentage of interest is the sum of the area of the central part of the distribution along with the lower tail:

  68% + 16% = 84%.
