Answer:
107.50
Step-by-step explanation:
Given the following :
Midpoint (S)____F
S y 93 95 97 99 101 103 105 107 109 111 f 19 25 38 17 12 10 5 4 4 2
Calculating the mean and standard deviation using a calculator :
The mean(m) of the data above = 98.12
Standard deviation (sd) = 4.02
Proportion = 99% of population
From z table = 2.33
Using :
Zscore =(x - m) / sd
2.33 = (x - 98.12) / 4.02
2.33 * 4.02 = x - 98.12
9.3666 = x - 98.12
9.3666 + 98.12= x
x = 107.4866
X = 107.50
The alphabet has 26 letters
Known facts:
- 50 dollars is the initial amount in the saving account
- 50 dollars is added every week into the savings account.
Variables:
- x: # of weeks
- y: total amount of money in savings
Set equation based on known facts and variables:
y = 50x + 50, 50x is the rate at which it grows depending on
the week and 50 is the initial amount there
Hope that helps!
