Answer:
Given
Ab = 12
A+b = 7
As a + b = 7,
A and b must be less than 7
A =6
B =2
Ab = 12
6 x 2 = 12
6, 2 < 7

Answer: 0.80
Step-by-step explanation:
Given : The owner of the West End Kwick Fill Gas Station wishes to determine the proportion of customers who pay at the pump using a credit card or debit card.
He surveys 100 customers and finds that 80 paid at the pump.
Then, sample proportion= 
Since , the best point estimate for population proportion is sample proportion.
Therefore, the estimated value for population proportion =0.80
An equation whose variables are polar coordinates is called a polar equation. These equation are characterized by an r as a function an angle. Polar equations can be written in rectangular coordinates by certain relationships. An example of a polar equation would be r = 2sin∅.
Answer:
18 terms
Step-by-step explanation:
The first given sequence has first term a1=2 and common difference d=5. Its explicit formula is ...
an = 2 +5(n -1) = 5n -3
We want the n-th term of this sequence to be the same as the n-th term of the sequence defined by ...
an = 4n +15
We can find n that makes this true by setting the 'an' values equal:
an = an
5n -3 = 4n +15
n = 18 . . . . . . . . . . add 3-4n
The number of terms in each sequence is 18.
_____
<em>Additional comment</em>
The last term in each sequence is 87.
