Step-by-step explanation:
d
Answer:
B) 1296 D) 729
Step-by-step explanation:
It's pretty straight forward, just put the values into your calculator. The question is asking to evaluate instead of simplifying, so this works. If you don't have a calculator, here are some tricks. Do them step by step in your head slowly if you have to, for fractions do them alone, and then divide them. Also in D, don't let the second value of (3)3)0 scare you, any exponent with a 0 in it is automatically 1! Hope I could help.
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
Y = 2/3x + 4 is the answer
because rise over run and the y intercept is 4 and it is a positive line
