Answer:
See below
Step-by-step explanation:
<u>The sequence given</u>
<u>We see the pattern: triple the previous term plus 1</u>
- 2) 19 = 6*3 + 1
- 3) 58 = 19*3 + 1
- 4) 175 = 58*3 + 1
<u>Next two terms</u>
- 5) 175*3 + 1 = 526
- 6) 526*3 + 1 = 1579
<u>Following two terms</u>
- 7) 1579*3 + 1 = 4738
- 8) 4738*3 + 1 = 14215
To find the mean you add all the numbers then divide by how many numbers there are :
8+16+12+11+8=55
in the equation there are 5 numbers, so you divide 55 by 5 :
55÷5=11
the mean is 11

15/x = 20/100
15*100 = 20*x
1500 = 20x
1500/20 = 20x/20
75 = x
15/75 = 20/100
the expected number of couples who met online is 75
Answer:
The day would be 3.125 seconds longer in 25 centuries.
Step-by-step explanation:
Let's break it down.
Each year, 1250 microseconds are added to the planet's day.
We need to find how long a day would be in 25 centuries.
A century is 100 years.
A second is 1,000,000 microseconds.
The day would be 3.125 seconds longer in 25 centuries.
Your points are (-2, 7) and (18, 1). To find the slope, use the slope formula (y_2 - y_1)/(x_2 - x_1)
(18, 1) --> (x_2, y_2)
(-2, 7) --> (x_1, y_1)
(1 - 7)/(18 - (-2)) --> -6/20 --> -3/10
The slope of the line passing through the points (-2, 7) and (18, 1) is -3/10.
