To estimate the mean score of those who took the medical college admission test on your campus, you will obtain the scores of an srs of students. from published information you know that the scores are approximately normal with standard deviation about 6.6 . you want your sample mean x¯ to estimate with an error of no more than 0.9 point in either direction. (a) what standard deviation must x¯ have so that 99.7% of all samples give an x¯ within 0.9 point of ? use the 68–95–99.7 rule. (enter your answer rounded to four decimal places.)

69.64%

step-by-step explanation:

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

no

explanation:

you can be freinds, and people but not follow people.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
