If this is a true or false statement then it is true
2 1/2 yards = 7.5 ft
7.5-1.5= 6
6 ft = 72 in
Anais used 72 inches of ribbon to trim the curtains.
You would do 50+25-45. That would equal 30 points.
Answer:
c)
Step-by-step explanation:
To solve this, remember some properties of trigonometric functions.
Let 
. Then, by definition of inverse function, 
. Multiply by -1 to both sides of this equation to get 
.
Note that 
because sine is an odd function and cosine is an even function. Then 
. Take the inverse tangent in both sides to get 
.
Using the previous equations, we obtain:
Answer:
B
Step-by-step explanation:
The expected value of profit margin is the sum of the product of profit margin and probability.
Wrench A:
... 10×.05 +20×.6 +30×.2 +40×.15 = 0.5 +12 +6 +6 = 24.5
Wrench B:
... (20+40)×.3 +(30+50)×.2 = 18 +16 = 34
Wrench C:
... 15×.4 +30×.5 +(45+60)×.05 = 6 +15 +5.25 = 26.25
Wrench D:
... 5×.2 +10×.4 +15×.15 +20×.25 = 1 +4 +2.25 +5 = 12.25
___
Clearly, Wrench B has the greatest expected profit margin. That would be the one Jose should order if he's trying to maximize his profit.
