Hi!
Ten less than the square of A.
So LESS is implying subtraction, therefore the 10 needs to be subtracted FROM something, If we look at our options, B is implying that 10 is being subtracted from something, which is what we want!
Therefore our answer is a^2-10
Hope this helps!
Answer:
x<44
Step-by-step explanation:
Answer:
x = -7
Step-by-step explanation:
f(x) = -2x + 9
f(x) = 23
therefore, f(x) =
-2x + 9 = 23
-2x = 23 - 9
-2x = 14
-x = 14 ÷ 2
-x = 7
x = -7
I think the correct answer would be A. The standard deviation is used than the variance because the units of variance are squared units. It does not say anything or is meaningless while standard deviation has the same units as the mean which is a measure of central tendency.
Answer: D
Step-by-step explanation:
The answer is (i) and (ii). In the first graph, as x approaches very large values such as infinity, the y-value will also approach infinity. In the second graph, as x approaches infinity, the y-value again approaches infinity.
On the contrary, the third graph approaches large negative values as x increases. It approaches negative infinity.
