Answer:
(x² + 4)(x - 3)
or
A
Step-by-step explanation:
Step 1: Write out expression
x³ - 3x² + 4x - 12
Step 2: Factor by grouping
x³ - 3x²
x²(x - 3)
4x - 12
4(x - 3)
Step 3: Combine
(x² + 4)(x - 3)
The standard normal curve is symmetric, so the area to the left of z = -1.25 is the same as that to the right of z = 1.25. Find one or the other and double your result.
To the left of 1.25: normalcdf(-1000, 1.25) = 0.1056, or 0.106. Double that; result is 0.212 (answer).
Answer:
5x4^10

Hope this helps have a nice day :)
The first equation has to be the sum of hotdogs and hamburgers. Since a total of 300 <span>hamburgers and hotdogs was sold, the first equation is:
h+d=300
Now, the second equation is about the money. They say that EACH hamburger cost $2 and each hotdog cost $1. And, the total amount of money made was $420. So the second equation is:
2h+d=420
SO, overall, the system of equations is this:
h+d=300
2h+d=420
