Answer:
Attachment
Step-by-step explanation:
x = 0
y = | 0 + 4 | - 1
y = 4 - 1
y = 3
y = 0
0 = | x + 4 | - 1
1 = | x + 4 |
x + 4 = 1 => x₁ = 1 - 4 => x₁ = - 3
x + 4 = - 1 => x₂ = - 1 - 4 => x₂ = - 5
The <em><u>correct answer</u></em> is:
0.0764
Explanation:
We will use a z-score to answer this. The formula for a z-score is
, where μ is the mean and σ is the standard deviation. Using our information in this problem, we have

Using a z-table, we look up the z-score 1.43. The area under the curve to the left of, or less than, this value is 0.9236. This means the probability that the time is greater than this is 1-0.9236 = 0.0764.

Answer:</h2>
Step 1: Determine <u><em>b</em></u> by using the point (-6,-2), the given slope, and the slope intercept formula, y = mx + b.

Step 2: Now that we have <u><em>b</em></u>, we can determine the equation of the line.

I didn't use <em>+ (-1)</em> because <em>b</em> is negative. Therefore you need to change the equation from <em>y = 1/6x + (-1)</em> to <em>y = 1/6x - 1</em>.
