Step-by-step explanation:
Step 1) Add 4 to both sides:
Although the graph is not given in the option, so I would consider it from a different graph with the same question. The graph that represents the area of each rectangle in terms of the change in the length and width is the one with coordinate points located on the grid. The coordinate points on the form of (x,y) are represented as:
1. (0,40)
2. (1,45)
3. (2,47)
4. (8,25)
Hence,The graph with these coordinate points will be representing the situation.
1. (0,40)
2. (1,45)
3. (2,47)
4. (8,25)
Hence,The graph with these coordinate points will be representing the situation.
Answer:
The probability that the stock will sell for $85 or less in a year's time is 0.10.
Step-by-step explanation:
Let <em>X</em> = stock's price during the next year.
The random variable <em>X</em> follows a normal distribution with mean, <em>μ</em> = $100 + $10 = $110 and standard deviation, <em>σ</em> = $20.
To compute the probability of a normally distributed random variable we first need to compute the <em>z</em>-score for the given value of the random variable.
The formula to compute the <em>z</em>-score is:
Compute the probability that the stock will sell for $85 or less in a year's time as follows:
Apply continuity correction:
P (X ≤ 85) = P (X < 85 - 0.50)
= P (X < 84.50)
*Use a <em>z</em>-table for the probability.
Thus, the probability that the stock will sell for $85 or less in a year's time is 0.10.
