Standard error of the mean is computed by:
Standard error = SD/ sqrt N
Where:
N is the sample size
SD is the standard deviation
To get the standard deviation, you need to get the sqrt of
the variance = sqrt 9 = 3
So plugging in our data:
Standard error = 3 / sqrt (16)
= 0.75
Answer:
The independent is the weight of all the people already on the elevator and the dependent variable is the weight of the elevator after you get on.
Answer: 152
Step-by-step explanation:
Let the number = x.
Therefore, x*25% = 38
25% as a decimal is 0.25.
So, 0.25x = 38
We can divide both sides by 0.25:
x = 152
Answer: Hello there!
in a deck of 52 cards, you have 26 red cards and 4 kings, where 2 kings are also red cards, so we could discard them.
We want to know the probability of drawing a red card or a king whem we draw at random, then all the cards have the same probability. This is the quotient between the number of red cards or kings and the total number of cards:
p = 26/52 + 2/52 = 28/52 = 0.48
then you have a 0.48 (or 48%) probability to get a red card or a king.
24/30
24/30
they are equivalent!
to get hte answer the closest denominator is 30 and to gwt 30 from 10 you multiply by 3 so 10x3=30 and 8x3=24 24/30. 12x2=24 and 15x2=30 24/30
