Answer:
s ≈ 105
Step-by-step explanation:
<u>Given:</u>
- The data set: 700, 735, 680, 890, 755, 740, 670, 785, 805, 1050, 820, 750
<u>To find:</u>
- The standard deviation of the data
<u>Steps:</u>
To find the standard deviation, first write the computational formula for the standard deviation of the sample.
Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by 
. Here, we round the standard deviation to the nearest whole number.
Rounding to the nearest whole number:
s ≈ 105
Given:
Initial point = (–5, 3)
Terminal point = (1, –6)
To find:
The set of parametric equations over the interval 0 ≤ t ≤ 1.
Solution:
The interval is 0 ≤ t ≤ 1, initial point is (–5, 3) and terminal point is (1, –6). It means,
Put t=1 in each parametric equation.
In option A,
In option B,
In option D,
Therefore, options A, B and D are incorrect.
In option C,
Put t=0 in x(t) and y(t).
Since, only in option C 
, therefore, the correct option is C.
It could be 55% is that an option?
I would try 30 but yeah ...
Answer:
D
Step-by-step explanation:
- 9 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Given
- 9
= (x³ )² - 3²
= (x³ + 3)(x³ - 3) → D
