Please answer this question!

Option B:

The mean low temperature of last week is 6.

Solution:

The daily low temperatures are:

-2°F, -3°F, -1°F, 8°F, 10°F, 12°F and 18°F.

Sum of the daily temperatures = -2 - 3 - 1 + 8 + 10 + 12 + 18

                                                   = 42

Number of days of the week = 7

Average = 6

The mean low temperature of last week is 6.

Option B is the correct answer.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

idk this answer sorry cant on this one.
