Answer:

x = 3

Step-by-step explanation:

Step 1: Add 4 to both sides.

3x−4+4=5+4

3x=9

Step 2: Divide both sides by 3.

3x/3 = 9/3

x = 3

Is the mistake one two three or is their no mistake
maria [59]

Answer:

the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)

the result would be that 2h-4 = 10  should actually be 2h-4 = 20

A factory makes car batteries. The probability that a battery is defective is 1/14. If 400 batteries are tested, about how many
Rufina [12.5K]

Answer:

28.6, that is, about 29 are expected to be defective

Step-by-step explanation:

For each battery, there are only two possible outcomes. Either it is defective, or it is not. The probability of a battery being defective is independent of other betteries. So the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

The probability that a battery is defective is 1/14.

This means that p = \frac{1}{14}

400 batteries.

This means that n = 400

How many are expected to be defective?

E(X) = np = 400*\frac{1}{14} = 28.6

28.6, that is, about 29 are expected to be defective
