Definitions:

Perpendicular bisector: A line that bisects (split into two equal parts) a line segment at a right angle (90°)

Angle bisector: A line that bisects a angle.

Median of a triangle: Line segment drawn from a vertex to the middpoint of the opposite side to the vertex.

Altitude of a triangle: Perpendicular segment form a vertex of a triangle to the opposite side.

a) With the given information you can describe FI as:

Median of triangle FGH:

Line segment drawn from a vertex (F) to the middpoint of the opposite side to the vertex (GH). The two marks in red indicates that the segments have the same measure (then the point I is the middpoint of the side GH.

Theres is not indication of a perpendicular angle, or a bisection of the angle. Then you can not describe FI as any of the other options.

Answer:

D. Both distributions are skewed left, so the interquartile range is the best measure to compare variability.

Step-by-step explanation:

Plotting the data roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.

In such a scenario, interquartile range is normally the best measure to compare variations of data.

Therefore, the last option is the best for the data provided.

a parking meter has 32 coins in nickels and quarters. the coins are worth $3.20. how many quarters and how many nickels are in t

BigorU [14]

Answer:

n = 24

q = 8

Step-by-step explanation:

Let:

n = nickels

q = quarters

5n + 25q = 320

n + q = 32

n = 32 - q

Substitute (to solve for q):

5(32 - q) + 25q = 320

160 - 5q + 25q = 320

160 + 20q = 320

20q = 320 - 160

20q = 160

q = 160 ÷ 20

q = 8

Substitute (to solve for n):

n = 32 - q

n = 32 - (8)

n = 24

Expand the following: 1/3(6/5x-3)

Strike441 [17]

x in (-oo:+oo)

(1/3)*((6/5)*x-3) = 0

1/3*(6/5*x-3) = 0
( 1/3 )

1/3 = 0

x belongs to the empty set

( 6/5*x-3 )

6/5*x-3 = 0 // + 3

6/5*x = 3 // : 6/5

x = 3/6/5

x = 5/2

x = 5/2

MATH HELP I NEED THE FULL EXPLANATION

olganol [36]

No

$({4}^{11} \times {4}^{1} ) ^{3}$
put 11 for p

${}^{11 + } {}^{1}$
add exponents. base stays the same
$({4}^{12} ) ^{3}$
multiply exponents. base stays same
$12 \times 3$
answer:
${4}^{36}$
His answer is inncorrect becase he added the exponents 12 and 3 instead of multiplying. You multiply exponents when one is raised to another.
for example:
$({2}^{2} ) ^{3 } \\ 2 \times 3 \\ {2}^{6}$
still check internet to make sure if im right.
