Abox contains 30 radio chips of which 10 are defective. if 7 chips are picked at random out of the box randomly, what is the probability that at least 8 are defective?

needs to show all work.

Answer the chace is 50%

Step-by-step explanation:

because if you  defined it then simplify it u get 50

Answer my question first

if one ratio is given find all other find sin30+cos30?

b

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
