An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in Texas. Suppose that the mean income is found to be $32.6 for a random sample of 1699 people. Assume the population standard deviation is known to be $8.8. Construct the 95% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place.

your answer is false.

replace the variable (x) with -3. insert it using parenthesis like this:

-35(-3) = -105

this statement is false because -35 multiplied by -3 is 105, not -105.

any line whose slope not equal to -4 does not satisfy these requirements.

step-by-step explanation:

going from (1,2) to (3, -6), x increases by 2 and y decreases by 8.   thus, the slope of a line thru those two points has the slope m = -8/2, or   m = -4.

thus, no line that has a slope different from m = -4 could be appropriate.

you can use the sas similarity.

a line dividing two triangle sides proportionally creates a new, smaller triangle whose angle is the same as the large triangle. its two sides are proportional to the large triangle. this implies the small and the large triangle are similar. similar triangles have all three angles the same. this implies the dividing line is parallel to the third side of the original triangle. lmk if you have questions.
