Answer:
n-16=29 doesn't belong
Step-by-step explanation:
When you solve all the equations, you get n=13, but n can't equal 13 when you plug it in the equation n-16=29. N would have to equal 45.
Answer:
<em>$40 </em>will be the total cost of the ribbon.
Step-by-step explanation:
To find the cost of ribbon to be put on the edges of rectangular banner, we need to:
1. Find the perimeter of the rectangle.
2. Multiply the perimeter with the per foot cost to find the total cost.
Let us find the perimeter first:
Perimeter of a rectangle is given as:
Here, the dimensions of rectangle are 4ft by 6ft.
So, perimeter =
It is given that per foot cost is $2.
Total cost of the ribbon =
<em>$40 </em>will be the total cost of the ribbon.
The answer is 4 hours and 26 minutes
Answer:
The Probability of exactly one tag being lost, in terms of π is
Step-by-step explanation:
Using the tree diagram attached to the bottom of this answer, you can see that the probability of only one tag being lost is the union of the probability of the left tag being lost when the right one is not lost and the probability of the right tag being lost when the left one is not lost.
Probability of losing only the right tag:
Probabilty of losing only the left tag:
Now, to unite those two probabilities, we use basic probability properties:
∪ ∩
Since the events are independent:
∩
So, the union becomes:
∪
Replacing:
