Answer:
0.91
Step-by-step explanation:
1 - P(both left handed)
1 - 0.3² = 0.91
Answer:
The system of inequalities is x ≥ 3y and x + y ≤ 10
The graph attached down
Step-by-step explanation:
* <em>Lets explain how to write the inequalities for this problem</em>
- Assume that x represents the quantity of regular coffee and
y represents the quantity of the decaffeinated coffee
- For a community breakfast there should be at least three times as
much regular coffee as decaffeinated coffee
- At least means greater than or equal
∵ x represents regular coffee
∵ y represents decaffeinated coffee
∵ x is at least three times as much as y
∴ x ≥ y ⇒ (1)
- A total of ten gallons is sufficient for the breakfast
- That means the quantities x and y shouldn't be more than 10
- Not more than means smaller than or equal
∵ The total quantity is 10 gallons
∴ x + y ≤ 10 ⇒ (2)
∴ The system of inequalities are
x ≥ 3y and x + y ≤ 10
* Lets graph (1) and (2)
- The red part for x ≥ 3y
- The blue part for x + y ≤ 10
Answer:
49 units
Step-by-step explanation:
10.50u ≥ 200 + 6.40u solve for u....
4.10u ≥ 200 (subtract 6.40u to both sides)
u ≥ 200/4.10 (divide both sides by 4.10)
u ≥ 48.78
Any number of units greater than 48.78, but they can't sell parts of a unit, so 49 is the minimum number of units that need to be sold to make a profit
Answer:
Simple,the answer would be 93200
Step-by-step explanation:
You move your decimal point backwards by the power e.g 10^6 u move backwards 6 times
What expressions? Will edit when I get it
