Step-by-step explanation:
The nearst rounding to the tens is 230
Answer:
-x - 3y + z
Step-by-step explanation:
Think of a imaginary 1(-1 because of the sign) in front of the parenthesis and distribute it to the other number and so x will become -x, 3y will become -3y and -z will become z because two negatives make a positive.
Answer:
Somewhere between 12 and 13, perhaps 12.25
Step-by-step explanation:
This is a (rather) simple explanation:
Look for 2 square numbers that are either side of 150
In this case, it is 144 and 169
The square root of 144 is 12 and the square root of 169 is 13
Therefore we can estimate that the square root of 150 is somewhere between 12 and 13.
As 150 is a lot closer to 144 to 169, I would estimate around 12.25 but you do not need an exact value :)
<span>Given are the following data:
Heart failure causes:
84% natural occurence
16% outside factors
18 individuals (sample size)
1. What is the probability that 3 individuals have conditions caused by outside factors?
Probability = 3/18 * 0.16 = 0.0267 or 2.67%
