A regular polygon has interior angles that are all equivalent. Because the interior angles of a polygon must add up to 360 degrees and since 55 cannot evenly go into 360, it is not possible for all the interior angles to be 55 degrees.

Line BC has an equation of a line Y equals 2X +3 and F has an equation of a line Y equals -1/2 x+4 these two equations represent

Masja [62]

Answer:

Lines BC and F represent perpendicular lines

Step-by-step explanation:

we have

Line BC

$y=2x+3$

the slope of the line BC is $m=2$

Line F

$y=-(1/2)x+4$

the slope of the line F is $m=-1/2$

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

$m1*m2=-1$

we have

$m1=2$ -----> slope line BC

$m2=-1/2$ -----> slope line F

Find the product of their slopes

$(2)(-1/2)=-1$

therefore

Lines BC and F represent perpendicular lines

The ages of people entering a pie eating contest are normally distributed with a mean of 35 years and a standard deviation of 8.

ELEN [110]

Answer:

The ages of people entering a pie eating contest are normally distributed with a mean of 35 years and a standard deviation of 8.2 years.

What is the age of a pie eating contestant with a z-score of −2.1 ?

[ Age - 35 ] / [ 8.2] = -2.1 multiply both sides by 8.2

Age - 35 = -17.22 add 35 to both sides

Age ≈ 17.8 years

I am doing the test right now !!! ;P

Graph 3x +4y=12 please

earnstyle [38]

To help us to graph the 3x + 4y = 12, we can isolate y

$\begin{gathered} 3x+4y=12 \\ \\ 4y=12-3x \\ \\ y=\frac{12}{4}-\frac{3}{4}x \\ \\ y=3-\frac{3}{4}x \end{gathered}$

Therefore it's a line with equation

$y=3-\frac{3}{4}x$

We have y = 3 when x = 0, and x = 4 when y = 0, therefore
