Answer:

lower limit is n=1

upper limit is n=18

n=1 to 18∑(7n-4)

Number of beads = 1125

Step-by-step explanation:

Given series is 3+10+17+24.....

we find the formula to find nth term(explicit formula)

first term (a1) = 3

common difference (d)= 7

a_n = a_1+(n-1)d

a_n = 3+(n-1)7

a_n = 3+7n-7

a_n =7n-4

total of 18 rows

So we find sum for n =1  to 18

lower limit is n=1

upper limit is n=18

n=1 to 18∑(7n-4)

(b) to find total number of beads we apply sum formula

s_n = \frac{n}{2}(2a+(n-1)d)

n=18, a=3, d= 7

s = \frac{18}{2}(2(3)+(18-1)7)

S= 9(125)=1125

Number of beads = 1125

postnew [5]

Answer:

The average cost of each dinner at Dave's party is <u>$5.79</u>.

Step-by-step explanation:

Given:

Dave ordered dinner for a party of 10 people.

Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each.

Now, to find the average cost of each dinner at Dave's party.

So, we get the total amount for the dinner:

Three people ordered the $4.75 chicken dinner.

4.75\times 3=14.25

Two people ordered the $4.95 fish dinner.

4.95\times 2=9.90

Five had the beef dinner at a cost of $6.75.

6.75\times 5=33.75

Total amount of dinner = 14.25+9.90+33.75=\$57.90.

Now, to get the average cost of each dinner of 10 people we divide the total amount of dinner by 10:

57.90\div 10

=\$5.79.

Therefore, the average cost of each dinner at Dave's party is $5.79.
