Answer:
4
Step-by-step explanation:
If the slope is 0, the line is horizontal and the y-coordinate is 4 for all x values.
Thus the missing y-coordinate is 4.
The number will be itself when multiplied by 1.
The sum of twice and half the original number is 1, so the number is
2n +0.5n = 1
2.5n = 1
n = 1/2.5 = 0.4
The original number is 2/5.
Using the normal distribution, it is found that the lengths for which a bolt will be destroyed are given by:
A. A bolt will be destroyed if the length is less than 11.8 cm or greater than 12.2 cm.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The bounds within 4 standard deviations of the mean are , hence:
X - 12 = -4 x 0.05
X = 11.8
X - 12 = 4 x 0.05
X = 12.2
Hence:
A. A bolt will be destroyed if the length is less than 11.8 cm or greater than 12.2 cm.

Answer:
The correct answer is c)
D: all real numbers
R: y ≤ 4
Step-by-step explanation:
We know this because a vertex is either a maximum or a minimum for the y value. Since the x-intercepts would be below the vertex, we know that the vertex must be a maximum.
Also, all parabolas will have a domain of all real numbers.
