you intend to estimate a popolulation mean with a confidence interval. you believe the population to have a normal distribution . your sample size is 4. find the critical value that corresponds to a confidence level of 91 %​

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

my answer is$ 12

step-by-step explanation:

because 15 -2=12

b. 2 and 4

step-by-step explanation:

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
