Answer: The area is
+ 18w
Step-by-step explanation:
We could represent the length of the yard by l = w+18 and the width as w .
And to find the area we will have to multiply the length by the width.
A= w(w+18 ) multiply
A=
+ 18w
Answer:
3 t-shirts
Step-by-step explanation:
<u>Lets recap the information we will use from this problem:</u>
The ticket to the festival costs $87.96
T-shirts are $30.00
She is taking $200.00 to the festival
Now we can solve. First we will subtract the price of the ticket from the total amount of money she has.
$200.00 - $87.96 = $112.04
Now that she has payed for the ticket, we want to find out how many shirts she can buy with the remainder of her money. To find this, we will set up an equation like this:
(Amount of money left) ÷ (Cost of 1 t-shirt) = (How many t-shirts she can buy)
Insert your numbers: $112.04 ÷ $30.00 = 3.73466666667
Because she cant buy a fraction of a t-shirt, we ignore the decimals on the end of this number. Therefore, Staci can purchase 3 t-shirts.
Answer:
56
Step-by-step explanation:
Multiply 14 by 4
You make $8.40 per hour $117.60 divided by 14 = $8.40 per hour
Ty makes $8.25 per hour $148.50 divided by 18 = $8.25 per hour
Kim makes $8.60 per hour $137.60 divided by 16 = $8.60 per hour
Kim has the highest pay rate in dollars per hour
Answer:
0.4460 = 44.60% probability that none of the 8 surnames of these authors were among the 10 most common
Step-by-step explanation:
For each surname, there are only two possible outcomes. Either they are among the 10 most common, or they are not. Each author is independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
These names account for 9.6% of all U.S. residents.
This means that 
8 authors in total.
This means that 
What is the probability that none of the 8 surnames of these authors were among the 10 most common
This is
. So


0.4460 = 44.60% probability that none of the 8 surnames of these authors were among the 10 most common
