Select the correct answer from each drop-down menu.
the publishers of a business magazine are running a sales promotion for their weekly magazine. the number of prospective customers a sales
representative sees per day varies from 1 to 40. the table shows the simulated data of the number of prospective subscribers approached by a sales
representative for 8 consecutive weeks.
day 1 2 3 4 5 6 7
week 1 20 22 27 17 31 12 39
week 2 26 13 30 18 24 14 32
week 3 21 12 22 37 30
week 4 15 33 10 28 34
week 5 11 33 21 32 26 19 22
week 6 19 27 20 18 31 14 37
week 7 29 22 27 30 16 09 36
week 8 08 28 19 28 25 36 26
if the sales representative is able to get 20% of the prospective customers to subscribe, the maximum expected number of subscriptions per
week is if the sales representative earns $3 per subscription in addition to daily wages, the minimum expected value of the extra
income per week is __

hope this !

let me know

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
