Amanufacturing machine has a 7% defect rate. if 5 items are chosen at random, what is the probability that at least one will have a defect? mhf

30.4%

Step-by-step explanation:

Probability that the 5 chosen are not defective = (1 - 0.07)^5

= 0.93^5

= 0.696

So the probability that there is at least one defective = 1 - 0.696

= 0.304

= 30.4 %

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
