<h3>Given</h3>
- Mean grade μ = 86,
- Standard deviation σ = 4,
- Grade limit x = 84.
<h3>To find </h3>
- Probability of that a randomly selected grade is less than 84 or P(x < 84).
<h3>Solution</h3>
Find z-score using relevant equation:
Substitute values and calculate:
Using the z-score table find the corresponding P- value.
- P(x < 84) = 0.30854 or approximately 31%
Answer:
5 and 1/2 quarts
Step-by-step explanation:
A quart is 2 pints
One half subtracted by one fourth is one fourth.
1/2 - 1/4 = 1/4
6.9 as a fraction or mixed number
6.9 = 6 9/10
This is also the same as 69/10
There would be 868 steps. since there is 245 MORE steps in castle be than in castle a, you would have to add 623 to 245
