Answer: the minimum score required for an A grade is 81
Step-by-step explanation:
Since the scores on the test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = scores on the test.
µ = mean score
σ = standard deviation
From the information given,
µ = 70.8
σ = 8.6
The probability value for the top 13% of the scores would be (1 - 13/100) = (1 - 0.13) = 0.87
Looking at the normal distribution table, the z score corresponding to the probability value is 1.13
Therefore,
1.13 = (x - 70.8)/8.6
Cross multiplying by 8.6, it becomes
1.13 × 8.6 = x - 70.8
9.718 = x - 70.8
x = 9.718 + 70.8
x = 81 to the nearest whole number
When an angle is bisected, it is split into two halves. If the original angle of 119 degrees is bisected, each new angle will equal half of 119, which equals 59.5 degrees.

Answer:
Step-by-step explanation:
The graph shows a linear function; the table does not. Thus, the first answer choice is incorrect.
Function g is exponential and eventually exceeds function f, which is linear; function g also has a greater average rate of change over [0, 2] than function f.
Function f has a greater y-intercept (15) than function g (8).
