Answer:
0.00009
Step-by-step explanation:
This question is an example of scientific notation.
To solve this you must
- Get it to standard form. If the exponent is negative, you move the decimal to the left. If the exponent is positive, you move the decimal to the right. Do it to the top and bottom.
- Now that you have it is standard form, simplify.

Answer:
The length of the ribbons in all were 25.3 meters.
Step-by-step explanation:
Given:
Lengths of the three pieces of ribbon were 10 meters and 9 decimeters, 3 meters and 10 decimeters, and finally 10 meters and 4 decimeters.
Now, to find the length of the ribbons in all.
So, by adding the length of all three pieces we get the length of all the ribbons:
.
Now, converting the decimeters into meters = 23 meters + 2.3 meters = 25.3 meters.
(1 decimeter = 0.10 meter)
(23 decimeter = 2.3 meter.)
Therefore, the length of the ribbons in all were 25.3 metres.
Answer:
Step-by-step explanation:
First, you description of ^ is very well written as well as being correct.
Second: all you can do is combine the 6 and 28. They are like terms
34 - c^3
That's as much of an answer as you can get.
Let's figure this out as though we have no idea what the answer would be.
Step One
Find the new five numbers.
3*3, 8*3, 12*3, 17*3, 25*3
9 , 24 , 36, 51, 75
Step 2
Find the average
(9 + 24 + 36 + 51 + 75)/5 = 195/5 = 39
Step 3
Subtract the individual numbers from the average
(39 - 9) = 30
(39 -24) = 15
(39 - 36) = 3
(39 - 51) = - 12
(39 - 75) = -36
Step 4
Square the results from Step 3
30^2 = 900
15^2 = 225
3^2 = 9
(-12)^2 = 144
(-36)^2 = 1296
Step 5
Take the average of the results from step 4
(900 + 225 + 9 + 144 + 1296)/5
2574 / 5 = 514.8
Step 6
Take the square root of the result from step 5
deviation = sqrt(514.8)
deviation = 22.689
Step seven
Compare the two standard deviations.
s2/s1 = 22.689 / 7.563 = 3
Conclusion
If you are given 1 set of numbers to find a population standard deviation and you multiply each member by a, then the result will be a * the standard population deviation of the first set of numbers.
Note
Your calculator will do this as well, but you have to know how to enter the data into your calculator. That requires that you follow the directions carefully.
Answer:
98 x 3 = 294 or 3 x 98 = 294
Step-by-step explanation:
Since 294 divided by 3 is 98, that means 294 is 3 times 98. So, we can say:
3 x 98 = 294
We can also say that 98 x 3 = 294 since it doesn't matter in which order you multiply.
