Answer:
you can do it bubu amp tanga
The best approach to this is to use the formular
Standard error = standard deviation / sqrt( sample size)
standard deviation = 0.75 hours
sample size = 35
Hence, Standard error = 0.75 /sqrt(35) = 0.126 = 0.13
The factors of 96 are
1,2,3,4,6,8,12,16,24,32,48,96
Answer:
(b) 4 x = 4 5 is the needed expression to solve for the value of x.
Step-by-step explanation:
Here, the given proportion is simplified as:
Now, to simplify any proportion of the form the simplest way is CROSS MULTIPLICATION.
So, cross multiplying
Similarly cross multiplying , we get:
4 (x) = (9) (5)
or, 4 x = 45
Hence, 4 x = 45 is the needed expression to solve for the value of x.
