How can you write an inequality to describe a situation?

For example let’s use something simple.

1+1 < 3+6
Why is this?
Because 1 +1 = 2 and that is less than 3 + 6 which is 9. Next time, apply this to something harder you might learn. I hope this helped <3

F= a+b+c over 3 solve for b

hoa [83]

1. $F = \frac{a+b+c}{3}$
2. $F3 = a+b+c$
3. $F3 - a = b+c$
4. $F3 - a - c = b$

1. Start
2. Multiply both sides by 3
3. Subtract a from both sides
4. Subtract c from each sides

ale4655 [162]

Answer:

231.00

Step-by-step explanation:

Carol earns 16 for 30 minutes, so $32 an hour, 32 * 3 = 96.

Peter earns 15 every 20 minutes, so 20 * 3 = 60 minutes, and 15 * 3 = 45,

so he earns 45 dollars an hour. 45 * 3 = 135

135+96 = 231.00

The probability that a lab specimen contains high levels of contamination is 0.10. A group of 5 independent samples are checked.

zhannawk [14.2K]

Answer with Step-by-step explanation:

In case of Bernoulli trails

The probability that a random variable occurs 'r' times in 'n' trails is given by

$P(E)=\binom{n}{r}p^r(1-p)^{n-r}$

where

'p' is the probability of success of the event

Part a)

probability that no contamination occurs can be found by putting r = 0

Thus we get

$P(E_1)=\binom{5}{0}0.1^0(1-0.1)^{5}=0.5905$

part b)

The probability that at least 1 contamination occurs is given by

$P(E)=1-(1-p)^{n}$

Applying values we get

$P(E_2)=1-(1-0.1)^{5}=0.4096$
