Answer:
2.9375% Rounded or 2.94% not rounded
Step-by-step explanation:
Prob (first defective) = 4 / 20 = 1/5
Prob(2nd defective) = 3/19
Prob (3rd defective) = 2/18 = 1/9
Pron 4th defective) = 1/ 17
Prob ( all 4 defective) = 1/5 * 3/19 * 1/9 * 1/17 = 1 / 4845 answer
Answer: Hope this helps!
Step-by-step explanation:
Area of a trapezoid formula base a+base b/2*h
Base a is the top length (22.5)
Base b is the bottom length (49.9)
Add those two lengths together (22.5+49.9=72.4)
Divide that by two (72.4/2=36.2)
Then multiply that by the height (36.2*23.8=861.56)
So your area is 861.56
The one you have marked is correct.
brainliest? if not, that’s okay. :)
The you find this is by first finding the slope. You do this by finding the difference between both x values and then both y values. You get 12(x), 6(y) then write it as a fraction. it is 12/6 which simplifies to 2. 2 is our slope. then you write it out in slope intercept form (y=mx+b) and plug in your numbers. pick one set of original points an put them in to x and y. now you just solve for b. this gives you -9 as b. you put it together to get
y=2x-9
hope this helps!!!! :)
