Hi there! :)

Answer:

\huge\boxed{y = 4x - 2}

Given line with an equation of y = 4x + 3

Parallel lines contain equivalent slopes, so a parallel line to the given equation would contain a slope of m = 4.

Plug in the coordinates of the point given, along with the slope into the equation y = mx + b where:

m = slope

y = y-coordinate of point

x = x-coordinate of point

Solve for the 'b' value, or y-intercept:

y = mx + b

6 = 4(2) + b

6 = 8 + b

b = -2

Rewrite the equation as slope-intercept form:

y = 4x - 2

The length of time, M hours that a phone battery will work before it needs recharging is normally distributed with a mean of 90
salantis [7]

Answer:

The interquartile range is between 83.25 hours and 96.75 hours

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 90, \sigma = 10

Find the interquartile range for this distribution.

That is, the middle 50%, from the 25th to the 75th percentile.

25th percentile:

X when Z has a pvalue of 0.25. So X when Z = -0.675

Z = \frac{X - \mu}{\sigma}

-0.675 = \frac{X - 90}{10}

X - 90 = -0.675*10

X = 83.25

75th percentile:

X when Z has a pvalue of 0.75. So X when Z = 0.675

Z = \frac{X - \mu}{\sigma}

0.675 = \frac{X - 90}{10}

X - 90 = 0.675*10

X = 96.75

The interquartile range is between 83.25 hours and 96.75 hours
