Answer:
513 turkey sandwiches were sold.
Step-by-step explanation:
Let's use 
to represent turkey sandwiches and 
to represent steak sandwiches.
= turkey sandwiches
= steak sandwiches
total sandwiches that were sold
dollars that were made
Now that we know what (steak sandwiches) equals, we plug it in to an equation to find .
Now, we subtract 5,550 from BOTH sides so we can get x by itself.
Next, we divide both sides by 2, so x is bare.
Since x represents turkey sandwiches, we have our answer: 513 turkey sandwiches were sold.
I hope this helps! :)

Answer:
5^(3)i^(9)= five cubes times i to the power of 9=125i
Step-by-step explanation:
Raise 5 to the power of 3
rewrite i9 as (i^4)2^i
so, you get 125((i^4)^2i)
i^4=1
125(1^2i)
125i

Answer:
0.98046
Step-by-step explanation:
Given:
Here we are required to find
P(5.48 <X<5.82) and between 5.48 and 5.82 we each z-score given by
<em>z = (x - μ) / σ</em>
So 5.48 we have z = -2.714 and 5.82 we have z = 2.143
Therefore we have the area of interest on the normal distribution chart given by
:
P( -2,714 < z < 2.143)
= 1 - P(Z<-2.714) + P(Z > 2.143)
= 1 - P(Z<-2.714) + (1 - P(Z < 2.143))
= 1 - 0.00336 + 1 - 0.98382
= 1 - 0.01954 = 0.98046
