You arrive at an intersection with traffic lights that are not working because of a power outage

Mathematics

Traffic rules are set by each individual state.

In most states, an intersection where traffic lights are out of order
is treated as if it were a 4-way STOP.

But you can't depend on this answer.  You MUST determine what
the law is in the state where you're driving.  And if you drive out of
state, it may change for you.

Treat the outage of the traffic lights like a stop sign.

Suppose a normally distributed set of data with 7800 observations has a mean of 188 and a standard deviation of 18. Use the 68-9
kompoz [17]

Answer:

7788 observations are expected to be below a value of 242.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 188, standard deviation = 18

The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.

Percentage of observations below 242:

242 = 188 + 3*18

So 242 is three standard deviations above the mean

Of the measures below the mean, all are below 242.

Of the measures above the mean, 99.7% are between the mean of 188 and three standard deviations above the mean(242). So the percentage is:

[tex}P = 0.5 + 0.997*0.5 = 0.9985[/tex]

Number of observations below 242:

99.85% of 7800 observations

0.9985*7800 = 7788

7788 observations are expected to be below a value of 242.

What is the answer to (12^2)^3 times 12^-4<br> and 12^7 times 12^-5 over 12^2
raketka [301]

Answer:  12² = 144

12² ÷ 12² = 1

Step-by-step explanation:

I'll go through it backwards: 12^7 times 12^-5  You subtract the -5 from 7 in the exponents to get 12^2.  12^2 divided by 12^2  is 1.

(12^2)^3 works out to 12^6 because you multiply the exponents when its a power raised by a power. Then you subtract the 4 from the 6 (or add -4 +6) to get 12^2.

That means 12 squared, same as 12 times 12

That's 144.

If you have to multiply the two parts together, It's 144 times 1.

If "and" means "add them together"-- YOU KNOW!
