Answer:

x = 2

Step-by-step explanation:

The 2 coordinate points have the same x- coordinate of 2

This indicates that the line passing through them is vertical with equation

x = c

Where c is the value of the x- coordinates the line passes through, thus

x = 2 ← equation of line

135% of what number is 108?

Allisa [31]

Answer:

N = 80

Step-by-step explanation:

of means multiply and is means equals

135% * N = 108

Change to decimal form

1.35 * N = 108

Divide each side by 1.35

1.35 * N/ 1.35 = 108/1.35

N = 80

Answer:

$x = 10 \\ y = 14$

Step-by-step explanation:

$\tan(45) = \frac{o}{x}$

$\tan(45) = \frac{10}{x }$

$a = \tan(45) \times 10$

$x = 10$

$\sin(45) = \frac{opp}{hyp} \\ \sin(45) = \frac{10}{y} \\ y = \frac{10}{ \sin(45) } \\ y = 14$

Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in "acid rain".

Aneli [31]

Using the normal distribution, it is found that 0.2119 = 21.19% of rainy days have rainfall with pH below 5.0.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

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

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:

$\mu = 5.43, \sigma = 0.54$

The proportion of rainy days have rainfall with pH below 5.0 is the <u>p-value of Z when X = 5</u>, hence:

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

$Z = \frac{5 - 5.43}{0.54}$

Z = -0.8

Z = -0.8 has a p-value of 0.2119.

0.2119 = 21.19% of rainy days have rainfall with pH below 5.0.
