Answer:
C. mental set
Step-by-step explanation:
A mental set generally refers to the brain's tendency to stick with the most familiar solution to a problem and stubbornly ignore alternatives. This tendency is likely driven by previous knowledge (the long-term mental set) or is a temporary by-product of procedural learning (the short-term mental set).

what is the greatest number of relative maximum that a polynomial of degree 15 can have? Select the right answer among them 1. 14 2. 6 3. 9 4. 7 5. 4
Answer:
7
Step-by-step explanation:
The greatest number of relative maxima it can have is 14.
So, the correct answer would be option (1) 14.
Use the concept of a polynomial defined as:
An expression that consists of exponents, variables, and constants and that is combining many different mathematical procedures:
Addition, subtraction, and multiplication is referred to as polynomial.
Given that,
The degree of polynomial = 15
The objective of this question determine the number of relative maxima it can have.
The number of relative maxima that a polynomial can have is equal to its degree minus 1.
In this case:
The polynomial is of degree = 15,
Hence,
The greatest number of relative maxima it can have is 15 - 1 = 14.
So, the correct answer would be option (1) 14.

A squirrel burrowed 10 holes in 8 minutes. How many holes could the squirrel burrow in 12 minutes?
Answer:
15
Step-by-step explanation:
Fast and loose: To go from 8 to 12 minutes you're adding half the time (4 minutes). So it has time to burrow only half the holes in the extra time, so 5. Total, 10+5=15.
Crunching numbers: it's a simple proportion:[tex]10:8 = x :12[/tex] from which, cross-multiplying you get [tex]8x=12\times10 \rightarrow 8x=120 \rightarrow x=15[/tex]

41. - 0.8
42. - 2.375
43. - 0.625
44. - 0.833
45. - 3.667
46. - 0.5
Step-by-step explanation:
Before reading this, every integer represents the whole amount, like 1 is 1 of something, 2 is 2 of something, 3 is 3 of something, and 4 is 4 of something.
1/5 = 0.2
1 - 0.2 = 0.8
1/4 = 0.25
1/8 = 0.125
1 + 1 = 2
0.25 + 0.125 = 0.375
2 + 0.375 = 2.375
3/8 = 0.375
1 - 0.375 = 0.625
2/3 = 0.667
1/2 = 0.5
4.5 - 3.667 = 0.833
1/2 = 0.5
1/6 = 0.167
2 + 1 = 3
0.5 + 0.167 = 0.667
3 + 0.667 = 3.667
1/4 = 0.25
0.25 x 2 = 0.5
