We can't really do this you will have to use your ruler and draw lines on the points. Example: For number 4, draw lines at 4 vertically on the x-axis and join it with another line on the y-axis. Then you can tell the answer. Sorry! Best of luck!

Answer:
260 is the minimum score.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 200
Standard Deviation, σ = 24
We are given that the distribution of test score is a bell shaped distribution that is a normal distribution.
Least marks required for admission in boarding school is 2.5 standard deviations above the mean.
Thus, we can calculate the minimum score as:
Thus, 260 is the minimum score that an applicant must make on the test to be accepted.
Here you have two sets of parentheses. Order of operations rules (PEMDAS) require that you perform any operations that are presented within parentheses first. Mult and div come next, and then any addition and/or subtraction.
We must perform the addition 4+8 first; the correct outcome is 12. Then we have:
16 • [(12)÷4]
We must perform the operation inside brackets first:
16*[3] = 48 (answer)
