Answer:

1/16

Step-by-step explanation:

first we find the probability of picking a 2 and then a 5 , then we multiply the two probabilities

probability of picking a 2 on the first time is 1/4 as there is 1 2 and 4 total cards.

the probability of picking a 5 is also 1/4 as there is 1 5 and 4 total cards

so the probability of picking a 2 and then a 5 would be 1/4 * 1/4 = 1/16

Find the sum of the interior angle measures of the green polygon,
Radda [10]

Answer:

The sum of interior angles of given polygon is 900°

Step-by-step explanation:

A regular polygon is a n-sided figure with n sides and the length of all sides is same.

In the diagram, we have a polygon with 7 sides.

The formula given is used to calculate the sum of interior angles of a polygon

Sum\ of\ interior\ angles = (n-2)*180

Here n is the number of sides of polygon

In the given polygon

n = 7

So,

Sum = (7-2)*180 = 5*180 = 900

Hence,

The sum of interior angles of given polygon is 900°

Evaluate this problem
sammy [17]
-5x-2y=2....(1)
6x-2y=24.....(2)
multiply (2) by -1,
-6x+2y=-24....(3)
add (1)+(3)
-5x-2y-6x+2y=2-24
-11x=-22
-11x/11=-22/11
x=2
plugging in the value of x in (1) 
-5(2)-2y=2
-10-2y=2
addind 10 to both sides
-2y=12
deviding both sides by -2
y=-6
so (x,y)=(2,-6)
