The team ran
juin [17]

The team ran 2 miles.

Step-by-step explanation:

Step 1; The track is \frac{3}{4} miles long and the team ran 2\frac{2}{3} laps on it. To calculate the distance run we multiply the number of laps ran with the distance on each lap.

Distance run = Number of laps × Distance on each lap.

Step 2; We convert 2\frac{2}{3} from a mixed fraction into an improper fraction. To do this, we multiply the whole number with the denominator of the fraction and add with it the numerator of the same fraction whereas the denominator remains unchanged. To convert the fraction 2\frac{2}{3} = ((2 × 3) + 2) / 3 = \frac{8}{3}.

Distance run = Number of laps × Distance on each lap = \frac{8}{3} × \frac{3}{4} = \frac{8}{4} = 2 miles.

Classify each substance as either a conductor or insulator.
IceJOKER [234]

A sample of mercury-conductor

A piece of glass-insulator

A rubber hose-insulator

A negatively ionized lithium paste-conductor

<u>Step-by-step explanation:</u>

Conductors are substances that allow the flow electricity through them whereas insulators do not permit the flow of electricity through them.

Mercury is  a liquid metal and due to its metallic nature, it is a fair conductor of electricity because metals have free electrons that carry the electric charge through the material.

Rubber and glass are insulators whereas a negatively charged lithium paste is a conductor.

X - 3= -21 <br>This is so confusing:(​
Aneli [31]

Answer:

\huge\boxed{x=-18}

Step-by-step explanation:

In order to solve this, we are trying to find the value of x. Basically, x is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.

Our goal is to find x. To do this we want to isolate x on one side of the equation

x-3=-21

Let's add 3 to both sides.

x-3 + 3 = -21+3\\\\-3 + 3 = 0\\\\x = -21+3\\\\x=-18

Hope this helped!

The length of a phone conversation is normally distributed with a mean of 4 minutes and a standard deviation of .6 minutes. What
Ivanshal [37]

Answer:

0.04746

Step-by-step explanation:

To answer this one needs to find the area under the standard normal curve to the left of 5 minutes when the mean is 4 minutes and the std. dev. is 0.6 minutes.  Either use a table of z-scores or a calculator with probability distribution functions.

In this case I will use my old Texas Instruments TI-83 calculator.  I select the normalcdf( function and type in the following arguments:  :

normalcdf(-100, 5, 4, 0.6).  The result is 0.952.  This is the area under the curve to the left of x = 5.  But we are interested in finding the probability that a conversation lasts longer than 5 minutes.  To find this, subtract 0.952 from 1.000:   0.048.  This is the area under the curve to the RIGHT of x = 5.

This 0.048 is closest to the first answer choice:  0.04746.
