Answer:
- 32, - 7, 18 and 127, 106, 85
Step-by-step explanation:
Add the common difference d to the previous term
(1)
a₁ = - 32
a₂ = a₁ + 25 = - 32 + 25 = - 7
a₃ = a₂ + 25 = - 7 + 25 = 18
The first 3 terms are - 32, - 7, 18
(2)
a₁ = 127
a₂ = a₁ + d = 127 - 21 = 106
a₃ = a₂ + d = 106 - 21 = 85
The first 3 terms are 127, 106, 85
Answer:
The correct set of hypotheses is
: d=80 degrees
: d>80 degrees
Step-by-step explanation:
The weatherman claims that the average temperature during July in Chattanooga is 80 degrees or less. To test this claim, following hypotheses need to be taken:
Let d be the the average temperature during July in Chattanooga, then
: d=80 degrees
: d>80 degrees
Answer:
4 1/2
Step-by-step explanation:
x/6 = 15/20
Cross multiply
X x 20 = 6 x 15
20x = 90
Divide both sides by 20
x = 90/20
x = 9/2
x = 4 1/2
Answer: 729 people are chosen in the sixth round.
Step-by-step explanation:
For a game, three people are chosen in the first round. Each of those people chooses three people in the second round. This means that the number of people chosen in the second round would be
3 + 3 + 3 = 9
This is 3²
If 9 people choose 3 people each in the third round, the total number of people chosen in the third round would be
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 27
This is 3³
This means that the number of people chosen at each round is 3^n
Where n represents the number of round. Therefore,
In the 6th round, n = 6
Number of people chosen is
3^6 = 729
