The first tern of an arithmetic sequence is -3 and the fifteenth term id 53. What is the common difference of the sequence?

1 answer:

5 0

The common difference is 4. U know that the formula is the first term + d(n -1). N-1 is 14 so u know that 14 times a number needs to equal 56 because the first term is -3 and 56-3 is 53. 14 * 4 is 56. So the common difference is 4

Step-by-step explanation:

<u>Let's simplify the problem:</u>

Joe has 5 + more than 2(P) as many calculators as John.

*We'll be using Addition and Multiplication operations.

If Joe has 5 more than 2 times the amount of calculators, the algebraic expression will be:

$5 + 2p$

p represents John's amount of calculators.

We want to compare the quality of three Tablet products: Tablet Product A has a Mean Time Between Failures (MTBF) 10,000 hours,

skelet666 [1.2K]

Answer:

The Availability of tablets A,B and C are equal

Step-by-step explanation:

Computation for Which tablet has better Availability

Using this formula

Availability of Tablet=MTBF/ ( MTBF + MTTR)

Where,

MTBF represent Mean Time Between Failures

MTTR represent Mean Time To Repair

Let plug in the formula

Availability of Tablet A = 10,000hrs/(10,000hrs + 10hrs)

Availability of Tablet A= 0.999

Availability of tablet B = 11,000hrs/( 11,000hrs + 11hrs )

Availability of Tablet B= 0.999

Availability of Tablet C = 12,000hrs/ ( 12,000hrs + 12hrs)

Availability of Tablet C= 0.999

Based on the above calculation the Availability of all the 3 tablets are equal

Therefore the Availability of tablets A,B and C are equal.
