now, let's recall the rational root test, check your textbook on it.
so p = 18 and q = 1
so all possible roots will come from the factors of ±p/q
now, to make it a bit short, the factors are loosely, ±3, ±2, ±9, ±1, ±6.
recall that, a root will give us a remainder of 0.
let us use +3.
well, that one worked... now, using the rational root test, our p = 6, q = 1.
so the factors from ±p/q are ±3, ±2, ±1
let's use 3 again
and of course, we can factor x²-x-2 to (x-2)(x+1).
(x-3)(x-3)(x-2)(x+1).
divide the price of the olive oil by the volume of the olive oil
to find the price per ounce. 5.88/25oz=0.2352 dollars/ounce. Then you
have to multiply the volume of the bottle by .60 to find what 60% of the
volume is.
0.60x25=15 ounces. since in the first two weeks she used 15
ounces which has a price of 0.2352 dollars/ounce you have to multiply
15 by 0.2352 which equals 3.528 dollars.
Answer:
The vehicle can travel 12 miles per gallon of gas.
Step-by-step explanation:
- The number of gallons used by a vehicle = 1 1/8 gallons
i.e.
gallons
- The number of miles traveled by a vehicle = 13 1/2 miles
i.e.
miles
Thus,
Total Gallons =9/8 gallons
Total Distance in miles = 27/2 miles
Hence:
Unit Rate = [27/2 miles] / [9/8 gallons]
= 12 miles per gallons ∵
Therefore, the vehicle can travel 12 miles per gallon of gas.
Substitution
x+3=-2+12
X+3=10
X=7
Answer:
Normally distributed with a mean zero.
Step-by-step explanation:
In multiple regression analysis, residuals should be Normally distributed with a mean zero.
In general, multiple regression is a technique to find more about the connection between many independent variables and dependent variables. It is simple a modern approach of a simple linear regression.
