SCORPION-xisa [38]

Answer:

y=930 x 075^x

Step-by-step explanation:

y is the price after the amount of years x being plugged into the equation. 930 is what you started with. 7.5 is what is being decreased so divide that by 100 and you get 0.075 plug in the amount of years into x and you have your equation

If n = 4, the value of the expression 28 – 12 + vñ : 2 is 0 15 021 O 017

Alexandra [31]

Answer:

Step-by-step explanation:

$28 - 12 + \sqrt{n} \div 2 =$

n = 4

$= 28 - 12 + \sqrt{4} \div 2$

$= 16 + 2 \div 2$

$= 16 + 1$

$= 17$

The two box plots summarize the number of hours spent in the weight room for all the players on the football team

iragen [17]

Options:

A. Players at school 1 typically spent more time in the weight room than players at school 2.

B. The middle half of the data for school 1 has more variability than the middle half of the data for school 2.

C. The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both schools are equal.

D. The total number of hours spent in the weight room for players at school 2 is greater than the total number of hours for players at school 1.

(See attachment for the box plots)

Answer:

C. The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both schools are equal.

Step-by-step explanation:

The median for school 1 is the value at the vertical line that divides the box of the box plot display of for school 1, which is 8

School 2 has a median of 9.

As we can see, the median for school 1 is less than the median of school 2.

Interquartile range is the range of the box.

Interquartile range for school 1 = 10 - 4 = 6

Interquartile range for school 2 = 13 - 6 = 6

As we can also see, the interquartile range for school 1 and that of school 2 are equal.

Which biconditional is NOT a good definition

ZanzabumX [31]

The answer is: [C]: Two angles form [a] linear pair if and only if the angles are adjacent.
_____________________________
{Your answer choice is correct! Good job!}.
_______________________________________
Explanation:
__________________
Consider the answer choice given in: "Answer choice: [C]" :
_______________________
"Two angles form linear pair if and only if the angles are adjacent."
_____________________________
Then, consider the following:
__________________
1) "Two angles that are supplementary form a linear pair."
Is this true? Yes, but not always. (In other words, "sometimes"). A "linear pair" of angles IS supplementary (by definition); however, NOT ALL supplementary pairs of angles are linear angles. Supplementary pairs of angles must ALSO be ADJACENT in order to be "linear angles" as well.
2) "Two angles that are vertical are adjacent." Is this true? No; this is NEVER true
_____________
As such, this biconditional is NOT a good definition; and by examining all the other answer choices given, we see that this answer choice "C" is correct.
__________________
Consider the other answer choices given:
_________________________________________
Answer choice: [A]: "Two angles are supplementary if and only if the sum of their angles measures 180." ;
 is INCORRECT because it is a good definition:
1) If 2 angles are supplementary, then the sum of their measures is 180 degrees.
2) If the sum of the measures of two angles is 180 degrees, then the angles are supplementary.
___________________________________
Answer choice: [B]: "Two angles are vertical angles only if they are not adjacent to each other and are formed by two intersecting lines.";
is INCORRECT because it is a good definition:
1) If two angles are vertical, then they are nonadjacent angles formed by two intersecting lines.
 2) If two angles are nonadjacent angles formed by two intersecting lines, then the angles are vertical angles.
_____________________________________
Answer choice: [D]: "The sum of two angles is 90 if and only if those angles are complementary" ;
is INCORRECT because it is a good definition:
1) If two angles are complementary, then the sum of their measures is 90 degrees.
 2) f the sum of [the measures of] two angles is 90 degrees, then the angles are complementary.
