Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² - 7x
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 3(-2)² - 7(-2)
- Exponents: f(-2) = 3(4) - 7(-2)
- Multiply: f(-2) = 12 + 14
- Add: f(-2) = 26

I don’t know but I’m struggling
Answer:
X= 4
Step-by-step explanation:
3x+6/3=6
multiply each side by 3 to get rid of the fraction bar
3x+6=6*3
3x +6=18
-6 from both sides
3x= 18-6
3x=12
divide by three on both sides to solve for x
x=12/3
x=4
3+3+4+3 im sure this is the answer just double chek
Answer:
the answer would be A, or 5.3%
Step-by-step explanation:
you start by finding the z-score of 200, so 200-144.05 = 55.95/34.52 = 1.62 (rounded to the nearest ) Then you use a z-score table to find the probability that a customer will spend less than 200 dollars and subtract the decimal probability from one. then you convert the decimal probability to a percent and get 5.3%.
