Answer:
270.1
Step-by-step explanation:
round to the nearest 10th or 100th if its 5 below it gone down 6 above go highter
First thing to do is set up your equation:
45/x = 20/100
Cross multiply
4500 = 20x
And divide by 20
Answer: 225 people were surveyed
So, for
T = 2 pi square m / k
the steps would be:
1) multiply by k
2) divide by <span>2π</span><span>
3) square</span>

Answer: the probability is 0.25
Step-by-step explanation:
We have 10 numbers:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Of those, the odd ones are:
1, 3, 5, 7, 9
So we have 5 odd numbers.
The probability that the outcome is an odd number is equal to the number of odd numbers divided the total number of numbers:
p = 5/10 = 0.5
For the second spin the probability is the same, p = 5/10, because the first outcome does not affect the results of the second spin.
The probability of spining an odd number both times, then is the joint probability for two times this same event:
P = (5/10)(5/10) = 0.5*0.5 = 0.25
or 25% in percent form
Answer:
4
Step-by-step explanation:
5/1=5
4-4+4-5+5=4
