What is the equation of a line l that has an x-intercept of (5, 0) and is perpendicular to another line m that has a slope -5?

Paul [167]

Answer:

$y=\frac{1}{5}x+5$

Step-by-step explanation:

Slope of a perpendicular line is the "negative reciprocal" of the slope of the original line (i.e $m=-5$ )

∴ $m=-\frac{1}{-5}=\frac{1}{5}$

the slope-intercept form: $y=mx+c$

with

$m=\frac{1}{5}$

and $c=5$

$y=\frac{1}{5}x+5$

ValentinkaMS [17]

Answer: They are wrong

Step-by-step explanation: x is given a value in the problem. Since x equals 4, We plug x into the equation.

y = 2(4) + 1

Y is actually equal to 9 minutes, not twelve.

A sensitive measuring device is calibrated so that errors in the measurements it provides are normally distributed with mean 0 a

Artemon [7]

Answer: 0.9660

Step-by-step explanation:

Given: Mean : $\mu =0$

Variance : $\sigma^2=2.00$

⇒ Standard deviation : $\sigma = \sqrt{2}$

The formula to calculate z is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x= -3

$z=\dfrac{-3-0}{\sqrt{2}}=-2.12132034356\approx-2.12$

The P Value = $P(z$

For x= 3

The P Value = $P(z$

$\text{Now, }P(-3$

Hence, the probability that a given error will be between -3 and 3=0.9660
