Deer mice (peromyscus maniculatus) are small rodents native to north america. their adult body lengths (excluding tail) are known to vary approximately normally, with mean millimeters (mm) and standard deviation mm. deer mice are found in diverse habitats and exhibit different adaptations to their environment. a random sample of deer mice in a rich forest habitat gives an average body length of mm. assume that the standard deviation of all deer mice in this area is also mm. the output from the graphing calculator for a confidence interval based on these findings is given: . , . (a) what is captured by this confidence interval?

step-by-step explanation:

i think you should think about the question and not look online.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
