The mean is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers. ... If no number in the list is repeated, then there is no mode for the list.

Daniel has a set off green,blue, and red the red marblesmmake up exactly 1halfs of the set the set has 2 blue marble the number

Blizzard [7]

Answer:

There are 12 marbles in Daniel's set.

Step-by-step explanation:

Given:

Daniel has a set off green,blue and red.

The red marbles make up exactly half of the set.

The set has 2 blue marbles.

The green marbles in set are as twice of the blue marbles in set.

Now, to find the number of marbles in Daniel's set.

Let the number of marbles in Daniel set be $x.$

So, the red marbles = $\frac{1}{2}\ of\ x$ $=\frac{x}{2}$

Blue marbles = 2.

And the green marbles = $2\times 2$ $=4.$

According to question:

$x=\frac{x}{2} +2+4$

$x=\frac{x}{2} +6$

$x=\frac{x+12}{2}$

Multiplying both sides by 2 we get:

$2x=x+12$

Subtracting both sides by $x$ we get:

$x=12.$

Therefore, there are 12 marbles in Daniel's set.

At a rate of 36 miles per hour, it takes Henry 15 minutes to drive from the library to his house. Show how to find the distance

EastWind [94]

This is applying the formula
$distance=rate*time$

We have a slight problem, though, because we are measuring rate in miles per hour, and we are measuring time in minutes. To make this problem solvable, we need to convert to either miles per minute or convert the time to hours. I'm going to convert the 15 minutes into hours:
$15min*\frac{1 hour}{60 min}=\frac{1}{4}hour$

Now that all of the units match, we have:
$distance=36\frac{mi}{hr}*\frac{1}{4}hr$

You can finish from there I'm sure.

The Richter scale is used for measuring the magnitude of an earthquake. The Richter magnitude is given R = 0.67log(0.37E) + 1.46

natka813 [3]

Answer:

7.9982

Step-by-step explanation:

-The function for an earthquake's magnitude is given by R = 0.67log(0.37E) + 1.46

-E is energy in kwh.

#For 15,500,000,000 kilowatt hours the magnitude would be:

$R = 0.67\ log(0.37E) + 1.46,\ \ E=15,500,000,000 \ kwh\\\\\therefore R=0.67 \ log(0.37\times 15,500,000,000)+1.46\\\\\\=7.9982$

Hence, the earthquakes magnitude is 7.9982
