Answer:
x=1 and x= -2.5
Step-by-step explanation:
✯Hello✯
The quadratic formula is x=-b+-(sqrt)b^2-4ac/2a
A = 2
B= 3
C = -5
PLUG THESE VALUES INTO THE QUADRATIC FORMULA
we can see that x=1 and x= -2.5

Answer:
0.03333
Step-by-step explanation:
Given that there are three machines. All of the machines can produce 1000 pins at a time.
Chance for any machine is thus equaly likely = 1/3
The rate of producing a faulty pin from Machine 1 be 10%, from Machine 2 be 20% andfrom Machine3 be 5%.
Machine I II III total
Faulty 0.10 0.20 0.05
Prob 0.3333 0.3333 0.3334 1
Faulty*prob 0.03333 0.06666 0.16665 0.26664
Thus probability that a produced pin will be faulty and it will be from the firstmachine
= 0.03333
Answer:
A = bh/2
39 = b*3/2
39*2 = b*3/2 * 2
78 = b*3
78/3 = b*3/3
26 = b.
Alors, la grande base est 26 cm et le petit base serait 26/3 = 8.67 cm arrondi.
To find this answer, you need to find a common denominator. A common denominator is when the number on the bottom of two fractions is the same. The easiest was to do this is to first multiply the two denominators, then multiply the numerator (or top number) by the opposite denominator. This sounds complicated, but it's pretty simple. Here's the equation written out. (I hope this helps!)
4*8 = denominator for both numbers.
8*1 = numerator for the first number
4*1 = numerator for the second number.
This should give you the fractions with common denominators, 8/32 and 4/32. Then, to compare the fractions, just see which numerator is larger. In this case, 8 is larger than 1 which shows that 1/4 is greater than 1/8.
I hope this made sense. There's more than one way to solve these problems, so comment below if you would like me to explain it differently and I'll get back to you as soon as I can! :)
