Answer: B = 100 - a^2
Solution:
Step 1: Substitute all the values that are given in the equation
that would be C = 25 and S = a
Step 2: when substituted the equation would be
B = 4 (25) - (a)^2
B = 100 - a^2 Would be the answer
Note: if there was a numerical value to s then the answer would be a number but since s=a so the answer has variable too.
False
Statistics data can be categorical too
The correct option is B): "There is no solution"
Answer:
1667
Step-by-step explanation:
(Margin of Error)² = (z × 0.5)²/n
Where n = number of samples
Minimum number of samples formula = (z × 0.5)²/ (Margin of Error)²
From the above question:
Margin of Error = 0.024
z = z score of a 95% confidence interval = 1.96
Minimum number of samples
= (1.96 × 0.5)²/(0.024)²
= 0.9604/(0.024)²
= 1667.3611111
Approximately to the nearest whole number = 1667
Therefore, the minimum number of samples is 1667
Answer:
A. Mean
Step-by-step explanation: Bc all Teachers average the grades using Mean.
Also if there is an outlire you need to use mean, Bc the Med won't be an exact average of the grades.
