Answer: 0
Step-by-step explanation:
Given that :
Mean score on test = 5
Standard deviation on test = 2
Distribution = normal
The mean value when Converted to a z - distribution :
Zscore = (x - mean) / standard deviation.
Hence z score for the mean score will be :
X = mean score
Zscore = ( 5 - 5) / 2
Zscore = 0 / 2
Zscore = 0
Mean value when Converted to a z distribution will be 0
2.828
Step-by-step explanation:
Given : Number = 8
To Find : find the square root of 8 upto 2 decimal places
Solution :
We are supposed to find the square root of 8
Group the digits into pairs
For digits to the left of the decimal point, pair them from right to left.
For digits after decimal point, pair them from left to right).
So, we have , 08
Refer the attached figure for further steps
√8 = 2.828
Hence the square root is 2.828
Since , you asked for 2 decimal places so the answer is:
Answer:
2.82
Step-by-step explanation:
√8=2*√2= 2*1.41= 2.82

Answer:
2.828 is the answer...
. Subtract 10x from both sides.
. Divide by 5 on both sides. x=20. So you would need to buy 20 movies.
The future worth of a certain item or money deposited at a certain percentage is obtained by the equation,
F = P x (1 + i)^n
F is the future worth, P is present worth, i is the percentage, and n is the number of years.
n = 2013 - 1938
n = 75
Substituting the known values,
300,000 = 100 x (1 + i)^75
The value of i from the equation is 0.1126.
The answer to this item is 11.26%.
Answer
Find out the what fraction of the sandcastle did they build together .
To prove
Let us assume that the fraction of the sandcastle they build together be x .
As given
Than the equation becomes
L.C .M of (3,7) = 21
solving
Therefore the fraction of the sandcastle did they build together be
Hence proved
