Answer:
30
Step-by-step explanation:
Given the radical values;
√1000
= √100 * √10
= 10√10
= 10 (3.1623)
= 31.623
Converting to nearest 10,
= 30
Hence the value to the nearest 10 is 30
Answer:
0.9662 ;
There is a strong positive relationship between the stocks.
Step-by-step explanation:
Given :
Standard deviation of stock X = 4.668
Standard deviation of stock Y = 8.006
Covariance of sample = 36.109
The Correlation Coefficient, r :
(Covariance of Sample (X, Y)) ÷ (standard deviation of X * Standard deviation of Y)
r = 36.109 / (4.668 * 8.006)
r = 36.109 / 37.372008
r = 0.9662
Given the value of the correlation Coefficient, we can infer that there is a strong positive relationship between the two stocks, (X, Y). That is Stock X increases as stock Y increases and vice versa.
Looks like a transformation of x^2 where it is stretched vertically.
When x = 1 , f(x) = 4 and when x = 2 f(x) = 16
Yes its f(x) = 4x^2
3 15/ 5 16 doesn’t need to be simplified
