Answer:

(i) Associative property of addition.

(ii) Commutative property of addition.

(iii) Inverse property of addition.

(iv) Identity property of addition.

Step-by-step explanation:

Associative property of addition: If a, b and c are three number, then

$a+(b+c)=(a+b)+c$

Commutative property of addition: If a and b are two number, then

$a+b=b+a$

Inverse property of addition: The sum of a number and its additive inverse (-a) is 0.

$a+(-a)=0$

Identity property of addition: The sum of a number and identity element 0 is the same number.

$a+0=a$

By using the above definitions we can say that

(i) A + (B + C) = (A + B) + C is Associative property of addition.

(ii) A + B = B + A is Commutative property of addition.

(iii) A + (−A) = 0 is Inverse property of addition.

(iv) A + 0 = A is Identity property of addition.

The residual plot for a data set is shown.

BaLLatris [955]

The correct answer is: <span>D. The regression line is not a good model because the points in the residual plot form a curve. (i know this because i just passed the test ;) )</span>

Prove that 1/sec0-tan0= sec0+tan0

Leviafan [203]

Answer:

Step-by-step explanation:

$\text{LHS}=\frac{1}{\sec \theta-\tan \theta}\\=\frac{\sec \theta+\tan \theta}{(\sec \theta-\tan \theta)(\sec \theta+\tan \theta)}\\=\frac{\sec \theta+\tan \theta}{\sec^{2} \theta-\tan^{2} \theta}\\=\frac{\sec \theta+\tan \theta}{1}\\=\sec \theta+\tan \theta\\=\text{RHS}$

Choose the best reason for using the median as the measure of central tendency.

Alchen [17]

Answer:

The median is usually preferred in these situations because the value of the mean can be distorted by the outliers. However, it will depend on how influential the outliers are. If they do not significantly distort the mean, using the mean as the measure of central tendency will usually be preferred.
