Answer: (-2.1)(3p)+(-2.1)(-5)

Step-by-step explanation:

Due to the -2.1 being on the outside of the parenthesis' you will distribute it into the (3p-5)

The first part will be (-2.1)(3p)

The next part will be +(-2.1)-5)

This is "+" due to a negative being multiplied by a negative.

(-2.1)(3p)+(-2.1)(-5)

Answer : Remaining two observation becomes 97 and 107.

Explanation :

Since we have given that

Mean = 100

Modal value = 98

Range = 10

As we know that ,

Range = Highest-Lowest

Let highest observation be x

Let lowest observation be y

So equation becomes x-y=10 ----equation 1

So, observation becomes

x,98,98,y

Now, we use the formula of mean i.e.

Mean = $\frac{\text{Sum of observation}}{\text{N.of observaton}}$

So, mean = $\frac{x=98=98+y}{4}=400\\\frac{196+x+y}{4}=100\\x+y=400-196\\x-y=204$

So our 2nd equation becomes

x+y=204

On using elimination method of system of linear equation on these two equation we get,

x=97

and

$x+y=204\\y=204-x\\y=204-97\\y=107$

Hence , remaining two observation becomes 97 and 107.

Mr williams went scuba diving and took photographs of the sea life at 25 feet below sea level. Write an integer to represent the

____ [38]

Hey You!

The integer would be: -25, because Mr. Williams was below sea level, and not above, so the integer that would represent this situation would be a negative integer.

That's Your Answer! ^^
