Answer:
False
Step-by-step explanation:
It is false because the absolute value signs mean that |-3| is actually positive 3. Absolute values are always positive. So, now you have 3 is less than or equal to 0, which is false because 3 is greater than 0.
The most expensive one is 40 so u dont need to add that one in so add up 18 22 and 35 and you get 75. So he spent $75 at the store.
2. unit price = $ ÷ oz
<span>a) 64 fl oz for $2 = 2/64 ≈ $0.031 per ounce </span>
<span>b) 256 fl oz for $7.5 = 7.5/256 = $0.029 per ounce </span>
<span>c) buy wholesale because 0.029 < 0.031 </span>
<span>3. unit rate means 1 for the miles </span>
<span>3/10 in ÷ 7/8 mi </span>
<span>= 12/35 inches per mile ...</span>
Answer:
42666 cases
Step-by-step explanation:
P = (Marginal Loss)/ (Marginal Loss + Marginal Profit)
P = (35)/(35+15) = 0.7
Considering a normal distribution we can find the corresponding z value by P = 0.7 (which represented the shaded area under the curve)
z = 0.5244
z = (X - Mean Sales)/Standard Deviation
-0.5244 = (X - 45000)/4450
X = 42666.42 ≅ 42666
Answer:
17
Step-by-step explanation:
The expression of interest is the difference of the two given expressions.
(-4x +6y) -(-2x -7y) = (9) -(-8)
-2x +13y = 17
The value is 17.

<em>Additional comment</em>
You could go to the trouble to solve the two equations for x and y, then compute the value of the expression you want. As we saw above, that is not necessary.
The first step in problem solving is always "look at the given information and how it relates to what you are asked." A little time spent doing that can save a lot of effort in the actual problem solving process.
