Answer: D) how close a measured value is to the actual value.
Step-by-step explanation: Accuracy is simply a measurement metric which is used to establish how a measured or predicted value conforms to the actual measurement usually in terms of closeness. Accuracy is different from precision which measures closeness in values obtained from repeated measurement of the same sample. For instance;
If the actual vale of a measurement is : 11.34
Prediction 1 : 11.30
Prediction 2 : 11.32 ;
Prediction 2 will be said to be more accurate than prediction 1 becuase it is closer to the actual value than prediction 1.
1. A polynomial means it has more than one term.
a. has 4 terms
b. has 1 term (not a POLYnomial)
c. has 3 terms
d. has 2 terms
2. The first word in a polynomial description tells the degree (max amount of exponents) of the expression, and the second word tells how many terms it has.
a. This answer means it's maxed exponent is to the fourth power, which it's not. (WRONG)
b. This answer means that it has a max exponent to the third power, which is true, and it also says it has three terms, which is also true. (CORRECT)
3. You must combine like terms in this polynomial.
=> 14x^2 - 6x^2 =8x^2
=> 5x + 2x = 7x
=> -8
d. This answer combines all the terms correctly.
4. To simplify this equation, you must first distribute the negative to all of the second equation.
(4x^2 -3x+2) + (-2x^2-5x+7)
Now, combine like terms.
=>4x^2 - 2x^2 = 2x^2
=>-3x - 5x = -8x
=>2 + 7 = 9
d. This answer simplifies it correctly

Step-by-step explanation:
Complementary angles have a sum of 90
32+2x+14=90
2x+46=90
2x=44
x=22 the second angle is 58
2(22)+14=58
Answer:
c) 1 2 4 8
Step-by-step explanation:
<u>Explanation </u>:-
<u><em>Geometric sequence</em></u>
The sequence is of the form a , a r , a r² , a r³ ,.......
'a' is the first term
'r' is the common ratio
1 , 1(2) , 1( 2)² , 1( 2 )³ ...... is a geometric sequence
here a = 1
common ratio 
<em>The sequence 1 2 4 8 is a geometric sequence</em>
