Answer:
Step-by-step explanation:
A_n = a + (n-1)d
a_n = -2n + 3
when n=1
a_1 = a = -2(1) + 3 = -2 + 3 = 1
when n = 2
a-_2 = -2(2) + 3 = -4 +3 = -1
a_2 = a + d
therefore,
a + d = -1
d = -1 - a
d = - 1 - 1
d = -2
Therefore the sequence is ,
1 , -1, -3, -5, -7.......
Answer:
640pi
Step-by-step explanation:
440pi + 200pi= 640pi
The square root for 8 is 2.82
A is true: the absolute value of 0.92 is close to 1, and 0.92 is positive.
B is false: correlation can also be negative.
C is false: the absolute value of -.17 is closer to 0 than 1; therefore, it is a weak correlation.
D is true: the absolute value of .01 is very close to 0, meaning that there is no significant correlation.
E is true: correlation can range from -1 (perfect negative) to 1 (perfect positive).
F is false: it measures the strength and direction between two numerical variables!
In conclusion, A, D, and E are true.
