The perimeter of a stop sign with 8 sides of equal length is 8n. What does the variable "n" represent?

The "n" in this expression will stand for the length of the sides.

Because we know there are 8 sides so 8xn will give us the perimeter.

A set of average city temperatures in May are normally distributed with a mean of 20.66 ^\circ \text{C}20.66

Angelina_Jolie [31]

Answer:

0.9962

Step-by-step explanation:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

$z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation, x=raw\ score$

μ = 20.66°C, σ = 2°C

For x < Singapore temperature, i.e. x < 26

$z=\frac{x-\mu}{\sigma} =\frac{26-20.66}{2}=2.67$

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962

Find the measure of angle b if angle a is 22 degrees and the whole angle is 300 degrees

Dima020 [189]

Answer:

$a = 278^{\circ}$

Step-by-step explanation:

Given

$b = 22^{\circ}$

$Whole\ Angle = 300^{\circ}$

Required

Find the measure of a

Since there is no diagram to support the question, we'll assume that:

$a + b = Whole\ Angle$

This gives:

$a + 22^{\circ} = 300^{\circ}$

Subtract 22 from both sides

$a + 22^{\circ}-22^{\circ} = 300^{\circ}-22^{\circ}$

$a = 300^{\circ}-22^{\circ}$

$a = 278^{\circ}$
