Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
240 is probably multiplied some other number if theres another number on there to multiply or divide by.
Common ratio (r) can be found by dividing the second term by the first term.
0.02 / -0.1 = -0.2
an = a1 * r ^ (n - 1)
a1 = first term = -0.1
r = common ratio = -0.2
an = -0.1(-0.2)^(n - 1)...answer is C
Answer:
1.4
Step-by-step explanation:
9.5+0.9t
=9.5+0.9(-9)
=9.5+-8.1
=1.4
