If h + 12 = 22, then h = 10.
This uses the subtraction property of equality, because if 12 is subtracted from both sides, we get the result of h = 10.
There is some inforrmation that is missing in this question. It should read:
<span><span>A container holds 50 electronic components, of which 10 are defective. If 6 components are drawn at random from the container, the probability that at least 4 are not defective is . If 8 components are drawn at random from the container, the probability that exactly 3 of them are defective is .

</span><u>Explanation</u>
The probability is a chance of an event happening. It is calculated as;
probability = (Number of favourable outcome)/(Number of available outcome)
Part 1
6 are chosen at random. If 4 are not defective, then 2 are defective.
P(at least 4 are not defective) = 4/40 </span>× 2/10
= 1/10 ×1/5
= 1/50
= 0.02
Part 2
8 are chosen at random. If 3 are defective, the 5 are not defective.
P(3 are defective) = 3/40 × 5/10
= 15/400
= 3/80
= 0.0375
Answer:
-1.3125
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3.1-(-3.2))/(-2.4-2.4)
m=(3.1+3.2)/-4.8
m=6.3/-4.8
m=-1.3125
Answer:
There is a one in six chance that a randomly selected radio plays country music.
Step-by-step explanation:
There is a 3/18 chance but that can be simplified if you divide both sides by 3 to get 1/6
