4/6, 8/12. 2/12, 3/36. multiply each fraction by 2/2 pretty much.
Answer:
A is the right anwser and the most reasonable.
Step-by-step explanation:
Probability = favorable event/total number of events
number of blue=6
total number of possibilities = 15
then P(blue)=6/15 = 2/5 =0.40
W replace it again (so the total number is always 15) & we draw a Red:
P(Red) = 5/15 =1/3 = 0.33
Answer:
a: $392.28
b: $112.08
Step-by-step explanation:
The decimal form of 40% is 0.4. Multiply 0.4 by 280.20, and you get 112.08
Because it is a markup, you add this 112.08 to your original price, 280.20
280.20+112.08=392.28
Your answer to letter a is $392.28
The rate of the markup is how much was added, so 112.08
Answer:
B
Step-by-step explanation:
The zeros ( where the graph crosses the x- axis ) are x = 2 and x = 6
The corresponding factors are (x - 2) and (x - 6) and the equation is the product of the factors, so
y = (x - 2)(x - 6) ← expand using Foil
y = x² - 8x + 12 → B
