Answer:
t ≥ 96 test score must be 96 or greater
Step-by-step explanation:
Let t - score on his third test
(75 + 81 + t) ÷ 3 ≥ 84
⇒ (75 + 81 + t) ≥ 84 x 3
⇒ (75 + 81 + t) ≥ 252
⇒ 156 + t ≥ 252
⇒ t ≥ 252 - 156 ≥ 96
The answer is D because the difference of the X and Y of both coordinates is 1, 3. If you halve that (0.5, 1.5) then add that to your first point (2, 2) then you get (2.5, 3.5) which is the same as (5/2, 7/2).
<span>Note that the mean (78 +90 +456 +676 + 111+ 381+ 21)/7 = 259
The differences (in absolute value - we're going to square later so it doesn't matter) between each piece of data and the mean are
181, 169, 197, 417, 148, 122, 238
Square each of these and add the results together to obtain 367452
Now your question depends on whether you want the sample standard deviation or population standard deviation - which you have not specified. In the first case divide by 6. In the second case divide by 7. We get roughly 61242 or 52493. The square root of each yields 247.47 or 229.11 depending on whether you want the sample sd or pop sd. The 4 choices imply you are looking for the latter, so the answer is A.i think</span>
Answer:
a₆ = 972
Step-by-step explanation:
Given a₁ = 4 and 
= 3
, then
a₂ = 3a₁ = 3 × 4 = 12
a₃ = 3a₂ = 3 × 12 = 36
a₄ = 3a₃ = 3 × 36 = 108
a₅ = 3a₄ = 3 × 108 = 324
a₆ = 3a₅ = 3 × 324 = 972
