Answer:
8.9 × 10^{4}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 89,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 89,000
New Number: 8.9000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 8 . 9 0 0 0
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 8.9 (Please notice any zeroes on the end have been removed)
b = 4
Now the whole thing:
8.9 x 10^{4}
Step 4
Check your work:
10^{4} = 10,000 x 8.9 = 89,000
Answer:
29/61
Step-by-step explanation:
okay, first imma simplify the question a little bit.
122 students; 46 chose football; 18 chose tennis; 28girls + xboys chose running.
okay now let's find the number of students who chose running
122 - 46 - 18 = 58
now, I'll find the probability
P(Running) = 58/122 = 29/61
