Answer:
Part A
Here the entire population is the total number of people who live in Scotland and the sample considered in this survey is the randomly chosen 34,572 people.
Part B
The approximations made out of the sample cannot be considered same as that of the entire population. Because here, only a random sample of 34,572 is taken whereas the total population here is the people who live in the Scotland, which can be quite large sample. The patient details recorded are used for survey. So in the sample surveyed we do not have the data about the rest of the population. The approximations made out of the sample become same as that of the entire population only if the entire population number is near to the randomly collected sample.

Answer:
Step-by-step explanation:
The element at row i column j in the product is the dot-product of row i of the first matrix and column j of the second matrix. For example, row 2 column 1 of the product is ...
(row 2) · (column 1)
[3, -2, 4] · [2, 7, 1] = (3)(2) +(-2)(7) +(4)(1) = 6 -14 +4 = -4
The attachment shows the complete product matrix. It is convenient to let a spreadsheet or graphing calculator do the tedious repetitive arithmetic.

Answer:
see the explanation
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In the coordinate plane, the x axis (y=0) and y axis (x=0) are perpendicular
however
this definition does not apply to the lines y=0 and x=0.
because
The slope of the horizontal line y=0 is equal to zero and the slope of the vertical line x=0 is undefined

Answer:
- √51 ≈ 7.141
- 1313/9900 ≈ 0.133
- ∛971 ≈ 9.902
Step-by-step explanation:
The usual rules of rounding apply. If the digit in the 4th decimal place is 5 or more, then 1 is added in the 3rd decimal place. The roots are found using your calculator. The first 4 digits of the repeating decimal are clearly visible already.
a) √51 ≈ 7.141428... ≈ 7.141
b) 0.1326_26 ≈ 0.133
c) ∛971 ≈ 9.90238... ≈ 9.902

<em>Additional comment</em>
The repeating decimal is equivalent to the fraction 1313/9900.
