Answer:
7.9
4.2
9.3
17.8
Step-by-step explanation:
8. √63
the square of 8 is 64 √63 is close to 64 so we can say it's 7.9 approximately
9. √18
the square of 4 is 16, √18 is greater than 16 so we can say it's 4.2 approximately
10. √87
the square of 9 is 81, √87 is greater than 81 so we can say the value of it is approximately 9.3
11. √319
the square of 18 is 324, √319 is smaller than 324 so we can say it's 17.8
Answer:
No
Step-by-step explanation:
No
Because a linear function is the form as
the highest exponent is one
and the graph is a line in the case of
is a parabola, not a line
Part (a)
<h3>Answer: 0</h3>
-------------------
Explanation:
Point P is part of 3 planes or faces of this triangular prism:
- plane PEF (the front slanted plane)
- plane PEH (the left triangular face)
- plane PHG (the back rectangular wall)
Notice how each three letter sequence involves "P", though this isn't technically always necessary. I did so to emphasize how point P is involved with these planes.
Each of the three planes mentioned do not involve line FG
- Plane PEF only deals with point F
- Plane PEH doesn't have any of F or G involved
- plane PHG only involves G
So there are no planes that contain line FG and point P.
==================================================
Part (b)
<h3>Answer: 0</h3>
-------------------
Explanation:
It's the same idea as part (a) earlier. The planes involving point G are
- plane GQF (triangular face on the right)
- plane GFE (bottom rectangular floor)
- plane GHP (back rectangular wall)
None of these planes have line EP going through them.
As an alternative, we could reverse things and focus on all of the planes connected to line EP. Those 2 planes are
- plane PEH (triangular face on the left)
- plane PEF (front slanted rectangular face)
None of these planes have point G located in them.
The estimated standard error for the sample is 6
Given,
Sample size, n = 36
Sample variance, 
= 1296
Standard deviation, s = √1296
= 36
Standard error, SE =

= 
= 6
Concept
- Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
- Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by ''
- Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’
