Find the common difference of the arithmetic sequence -2,6,14,...

Mathematics
1 answer:
yawa3891 [41]2 years ago
8 0

Lets note the change between each of the numbers in the sequence:

-2 --> 6 ---> 14

Next, make an equation between each of these numbers with x being the change between them

-2+ x = 6, 6 + x = 14 .

Now, solve each of these equations:

-2+ x = 6 --> -2+ x = 6 <em>Add 2 on both sides to cancel out the -2 </em>--> <em>x = 8</em>

6+ x = 14 --> -2+ x = 6 Minus <em>6 on both sides to cancel out the 6 </em>--> <em>x = 8</em>

<u><em>From this, the common difference will be 8.</em></u>

Hope that helps.

If you convert 840,000 to scientific notation; you would take 840,000 and divide it by 10^5 (ten to the fifth power) which is 100,000 and that would leave you with 8.4 divided by 10^5. Remember scientific notation must be expressed as a number 1 through 9 but less than 10.

store announced that their $500 appliances were on sale for $475 what is the percent discount on the appliances
Aleks04 [339]

Answer:

We are given that a store announced that their $500 appliances were on sale.

The price of the appliances after discount is $475.

We are required to find the percent discount on the appliances.

To find the percent discount, we have to use the below formula:

\frac{(Actual-discounted)}{Actual} \times 100\%

\frac{500-475}{500}\times 100\%

\frac{25}{500} \times 100\%

0.05 \times 100\%

5\%

Therefore, the percent discount on the appliances is 5%

Let pn, n = 0,1,2,..., be the probability that an automobile policyholder will file for n claims in a five-year period. the actu
lara31 [8.8K]
<span>P(1 claim) = p/4
P(2 claims) = (p/4)/4 = p/16

You should see that the distribution follows a geometric series with common ratio 1/4.
Sum geometric = (first term) / (1 - common ratio) = p/(1 - 1/4) = 4p/3

But the sum of all the probabilites must equal 1 ----> 4p/3 = 1 ----> p = 3/4

P(2 or more claims) = 1 - P(0 claims) - P(1 claim) = 1 - 3/4 - 3/16 = 1/16</span>

Answer:

a) Rumble: $1

Pedal: $0.6

b) more than 5 songs

c) No, should be integers only

d) No, has to be integers greater than or equal to 2

Step-by-step explanation:

Part a

Rate per song is the slope.

Rumble:

Slope is 0.6

Rate is $0.6 per song

Pedal:

Slope: (4-2)/(2-0) = 1

Rate is $1 per song

Part b

Pedal would be a better deal if it's cost is lower than Rumble's

Rumble's cost: C = 2 + S

Pedal's cost: C = 4 + 0.6S

4 + 0.6S < 2 + S

0.4S > 2

S > 5

c) No, because no. of songs has to be positive integers only.

For example graph shows S = 2.5, but we know that's not possible

d) No, since the cost is 2 + S,

cost can't be in decimals either.

Cost too should be only integers greater than equal to 2
