Answer:
11) 75.2
12) 44.2
Step-by-step explanation:
angles formed by intersecting lines tangent to a circle are the same length.
11)
Perimeter = 2(5) + 2(12) + 2(11.4) + 2(9.2) = 75.2
12)
Perimeter = 2(4) + 2(8) + 2(5.3) + 2(4.8) = 44.2
1. 28.57
2. 16
Hope this is right.
Answer:
C) aₙ = aₙ₋₁ + 200
Step-by-step explanation:
Each term is 200 more than the previous term. So:
aₙ = aₙ₋₁ + 200
Answer:
Option D (Yes. The model is a good fit because the residual plot does not have a random pattern).
Step-by-step explanation:
First of all, insert all the data in Microsoft Excel. Make sure that the values of X are in the ascending order. Then, make the scatter plot of the data with the line of best fit from the Insert option. The graph shows that there is a positive relation between x and y. Most of the actual values of y lie very close to the line. A very few observations are a little further from the line of best fit. Therefore, the model is a good fit because the residual plot does not have a random pattern. Option D is the correct answer!!!
Answer: There are 863,040 possible ways
Step-by-step explanation: There are 32 members altogether in the club. So in order to elect a president from among all of them, if every one of them has a chance if being elected, there would be 32 possible chances for every single club member.
However, as long as one member has been elected as president, that leaves others with a 31 chance per person arrangement.
Therefore, all possible permutations of electing four officers from a club of 32 members can be expressed as
32! (Thirty two factorial) which can be simplified as
32 x 31 x 30 x 29 and that equals 863,040.
863,040 possible ways of electing four officers from a club of 32 members.
