There are 10 yellow, 6 green, 9 orange, and 5 res cards in a stack of cards turned face down. once a card is selected, it is not

Vika [28.1K]

Answer:

10+6+9+5= 40

So there are

$\frac{10}{40}$ are yellow cards $\frac{6}{40}$ are green cards $\frac{9}{40}$ are orange cards $\frac{5}{40}$ red cards

now we have to get the percentages

$\frac{10}{40}$ = $\frac{25}{100}$

$\frac{6}{40}$ = $\frac{15}{100}$

$\frac{9}{40}$ = $\frac{22.5}{100}$

$\frac{5}{40}$ = $\frac{12.5}{100}$

so the probability of getting...

yellow is 25%

green is 15%

orange is 22.5%

red is 12.5%

ABCDEFGHI is a regular 9-sided polygon.

Igoryamba

Answer:

angle BEF = 100 degrees

Step-by-step explanation:

For a regular 9-sided polygon (nonagon),

each exterior angle = 360/9=40 degrees

each interior angle = 180-40 = 140 degrees.

Referring to diagram, in the trapezoid (trapezium) BCDE, the base angles are 180-140 = 40 degrees.

Therefore angle DEB = 40 degrees

that leaves BEF = 140-40 = 100 degrees
