5 2/3 * 3/4 = 4 3/12
to find the answer you multiply 5*3 to get 15 you then add 3 to get 17. 17 is your new numerator and 3 stays as the denominator. you then multiply 17 and 3 to get 51. you now multiply the denominators to get 12. 12 goes into 51, 4 times. you get 48. 51-48= 3. so the answer is 4 3/12 hope this helps :)

iragen [17]

Answer:

$H_A: P_{\text{Internet}}-P_{\text{Store}} > 0.10$

Step-by-step explanation:

We are given the following in the question:

Let $P_{\text{Internet}}$ be the proportion of the internet sales and $P_{\text{Store}}$ be the proportion of the store sale.

Hypothesis:

We have to conduct a hypothesis to check that the Internet sales are more than 10 percent higher than store sales.

Thus, we can design the null and alternative hypothesis as:

$H_{0}: P_{\text{Internet}}-P_{\text{Store}}\leq 0.10\\H_A: P_{\text{Internet}}-P_{\text{Store}} > 0.10$

Alternate Hypothesis:

The alternate hypothesis states that the proportion of the internet sales is greater than the proportion of store sales by 10 percent.

an=4n+1

Sum of first 30 terms

a1+a2+.................a30

Sn=(a1+an)*n/2

a1-----------first terms

an=---------last term-----a30

n= number of terms-----30

calculation of a1

a1=4n+1=4*1+1=5

calculation of an

a30=4*30+1=121

S30=(a1+a30)*30/2

S30=(5+121)*30/2=1890

<span>The sum of first 30 terms is 1890</span>
