Answer:
a) Between 74 and 90
b) 81.86% of the scores are between 78 and 90
Step-by-step explanation:
a) According to the Empirical Rule, in a normal distribution, 95% of the data are within 2 standard deviations of the mean. Therefore, the range that 95% of the scores fall in is between 82-4(2)=74 and 82+4(2)=90.
b) The percent of scores that are between 78 and 90 is: normalcdf(lower,upper,μ,σ) = normalcdf(78,90,82,4) = 0.8185946784 ≈ 0.8186, or about 81.86% of the scores.
Answer:
If its a cube function. Then I think this is the answer. Can you mark brainliest? And can you tell me if it's right or wrong?
Step-by-step explanation:
Consider the cubic function f(x) = ax^3 + bx^2 + cx + d. Determine the values of the constants a, b, c and d so that f(x) has a point of inflection at the origin and a local maximum at the point (2,...
Consider the cubic function f(x) = ax^3 + bx^2 + cx + d. Determine the values of the constants a, b, c and d
so that f(x) has a point of inflection at the origin and a local maximum at the point (2, 4). ==>c=3

Answer: True
Step-by-step explanation:
Cost = 15 + 3t
22.5 = 15 + 3(2.5)
22.5 = 15 + 7.5
22.5 = 22.5 <— true
