Answer:
Step-by-step explanation:
The given sequence is
64, 16, 4, 1
It is a geometric series because it has a common ratio 
.
First term is 64.
The explicit formula of a geometric series is
where, a is first term and r is common ratio.
Substitute a=64 and r=1/4 in the above function.
Therefore, the required explicit formula is .
If you want to eliminate x than multiply equation 1 by 4 and equation 2 by 3 and subtract them or,
If you want to eliminate y than mutiply equation 1 by 8 and equation 2 by 11 and subtract them.
Answer:$5408
Step-by-step explanation:
The first company offers a straight commission of 5% of the sales. This means the salary or income is 5% of sales made.
The second company offers a salary of $260 per week plus 4% of the sales. This means salary or income
= $260 +4% of 260
= 260 + (4/100)×260
= 260 +(0.04×260)
=260+10.4 = $270.4
Let x = the amount of sales you would have to sell in a week in order for the straight commission offer to be at least as good
5% of x should be greater than or equal to $270.4
0.05x = 270.4
x = 270.4/0.05 =$5408
The sales should be greater than or equal to $5408
Match the data to the summary 5,10,15,20,25,25,25,30,35,40,45,50
Serjik [45]
Minimum = 5
maximum = 50
Q1 = (15 + 20)/2 = 17.5
Q2 (median) is 25
Q3 = (35 + 40)/2 = 37.5
