Answer:
0.3745
Step-by-step explanation:
We have to solve the problem by calculating the z-score value that has the following formula:
z <(x - m) / sd
x is the value to evaluate (<80), m is the mean (85) and the standard deviation is sd (12)
replacing:
p (x <80) = z <(80 - 85) / 12
z <-0.416, we look for this value in the normal distribution table and it corresponds to:
p (x <80) = 0.3745
Which means that the proportion of people is 0.3745
Answer:
The new value after an increase
of £258 by 43 will be: 368.94
Step-by-step explanation:
As we have to increase £258 by 43 using the multiplier method.
Let 'n' represent the new value after the increase of £258 by 43 using the multiplier method.
Using the formula
n = 258 + percentage increase
Factoring out 258
as 1 = 100 / 100 = 100%
so
Therefore, the new value after an increase
of £258 by 43 will be: 368.94
