Determine if JK and LM parallel, perpendicular, or neither .

Digiron [165]

Answer:

3 - Perpendicular.

4 - Parallel.

Step-by-step explanation:

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$JK = \frac{1-(-7)}{-4-(-10)} = \frac{8}{6} = \frac{4}{3}$

$LM = \frac{-2-2}{-6-(-3)} = \frac{-4}{3}$

Perpendicular, because two lines are considered perpendicular if their slopes are opposite reciprocals.

$JK = \frac{-2-(-2)}{3-11} = \frac{0}{-8} = 0$

$LM = \frac{-2-(-7)}{1-1} = \frac{5}{0} = 0$

The Orchard Cafe has found that about 15% of the diners who make reservations don't show up. If 77 reservations have been made,

taurus [48]

Answer:

65 dinners are expected to show up

The standard deviation of the distribution is 3.13

Step-by-step explanation:

Given

Proportion = 15%

Population = 77

Required

Expected Number that'll show up

Standard Deviation

If 15% won't show up; then

100% - 15% = 85% will show up

Expected Number, E(x) of Dinner is calculated as thus;

$E(x) = np$

Where $p = 85\%$ (calculated above)

and $n = 77$

Convert p to decimal

$p = 0.85$

So;

$E(x) = 0.85 * 77$

$E(x) = 65.45$

$E(x) = 65$

65 dinners are expected to show up

Calculating Standard Deviation, SD

Standard Deviation is calculated as;

$SD = \sqrt{np(1-p)}$

Substitute 0.85 for p and 77 for n

$SD = \sqrt{77 * 0.85 * (1-0.85)}$

$SD = \sqrt{77 * 0.85 * 0.15}$

$SD = \sqrt{9.8175}$

$SD = 3.13328900678$

$SD = 3.13$ (Approximated)

The standard deviation of the distribution is 3.13

A bag contains hair ribbons for a spirit rally.The bag contains 3 black ribbons and 12 green ribbons.Lila selects a ribbon at ra

djverab [1.8K]

3 black ribbons and 12 green ribbons
so P(Lila selects a black ribbon)=3/(3+12)
=1/5
2 black ribbons and 12 green ribbons left
P(Jessica selects a green ribbon)=12/(12+2)
=6/7

so P(Lila selects a black ribbon and Jessica selects a green ribbon)
=1/5*6/7
=6/35
