Answer:

8.4x10^5 is the first answer. 9.16 x 10^-6 is the second one.

Step-by-step explanation:

Let me explain. To find scientific notation of a number, you have to make the number greater than 1 and less than 10. So for the first number, you would have to move a decimal place 5 times to the right to make 840,000 less than 10 and greater than 1. But, you still have to add the exponent. So the amount of numbers you move the decimal point to the left, that will be your exponent.

2nd. BUT, for the 2nd number, this number is not 1 or greater than 1 or less than 10. So you would have to move it to the right. If your moving a number to the right, remember the exponent will always be negative. So you would move it 6 times to the right.

I hope this made sense. If it didn't, don't worry! You'll get the hang of it.

Find the degree of the polynomial: −3x^3y^3+2.5xz^2−5xz^2

Lilit [14]

Answer:

Degree is 6

Step-by-step explanation:

Solving given polynomial gives -3x^3y^3-2.5xz^2

as this polynomial involves two variables so we'll add the powers on variables in each term

first term: -3x^3y^3, add powers on x and y variables which turns out to be 6

Second term: 2.5xz^2, adding powers on x and z variable results in 3

As degree is the highest power among different powers on terms so here the degree is 6

Whats the mean, media, maximum,minimum,mode and range of 1,2,1,3,4

ludmilkaskok [199]

First put the numbers in order least to greatest.
(1,1,2,3,4)
The mean is the average of the group of numbers.
Too find it you add all the numbers up and divide it by how many numbers there are.
In this case it would be 11 divided by 5 so the mean would be $2 \frac{1}{5}$

Median is just another word for middle. After putting the numbers in order, the number in the center of the group is the median, in this case it would be 2.

The maximum would just be the largest number which is self explantory (4)

The minimum would be the lowest number (1)

I was taught to see mode as the word "most". All you do is see which number occurs the most. If all the numbers only occur once, your answer would be "No mode"

It is that simple! The Range is the difference between the lowest and highest number. So all you have to do is subtract the maximum by the minimum. In this case it would be 4-1 = 3
