The lumen output was determined for each of i = 3 different brands of lightbulbs having the same wattage, with j = 10 bulbs of each brand tested. the sums of squares were computed as sstr = 590.6 and sse = 4772.9. state the hypotheses of interest (including word definitions of parameters).

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

b is the correct answer

hi there!

the answer is: 2 and -2

step-by-step explanation:

case 1: an absolute value of positive number will still be a positive number

so absolute value of 2 is 2

case 2: an absolute value of negative number will be positive number so absolute value of -2 is 2
