The high temperatures in montana are recorded for a week. high temperatures sunday 46°f monday 52°f tuesday 51°f wednesday 54°f thursday 49°f friday 51°f saturday 61°f what is the mean, or average, high temperature for the week? how many degrees fahrenheit

Average high temp is 52 degrees F

Step-by-step explanation:

to find the mean, add them all up, then divide by how many numbers you added

add the all up:  (46+52+51+54+49+51+61) = 364

then divide by 7

364/7 = 52

52

Step-by-step explanation:

to get the mean you need, add up all the numbers

46+52+51+54+49+51+61=364

then divide by the number of numbers that you have

364 divided by 7=52

then you will get 52 degrees fahrenheit

step-by-step explanation:

all of the other ones have a specific pattern

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
