The histogram below shows the age distribution of Elizabeth’s grandchildren. A bar graph entitled Ages of Elizabeth apostrophe s Grandchildren has ages on the x-axis and number of grandchildren on the y-axis. She has 2 grandchildren between the ages of 0 to 4; 4 between 5 to 9; 4 between 10 to 14; 2 between 20 to 24. The box-and-whisker plot below shows the same data. A box-and-whisker plot is shown. The number line goes from 0 to 24 in increments of 2. The whiskers range from 1 to 24, and the box ranges from 5 to 13. A line divides the box at 8. Which of the following best explains why one graph appears skewed and one graph appears symmetric? The intervals on the x-axis of the histogram are too large. The interval on the y-axis of the histogram is too small. The interval on the x-axis of the histogram is inconsistent. The interval on the box-and-whisker plot is too small.

da freeck kinda math is this just drop out

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
