Help! Don’t know, pls help! Pls show you work too, thank you!

Answers:

In other words, only choice C is false while the others are true.

Explanation:

The height of each bar represents the frequency for each group. It tells us how many students are in a certain interval. For example, the first bar has a height of 3 units to indicate there are 3 students between 140 and 155 cm.

Add up the heights of each bar to find the total number of students: 3+5+6+5+3+2 = 24

Statement A is correct because there are 24 students.

Statement B is also correct. This is because the highest value on the x axis is 230 and the lowest is 140. The range is the distance or gap between them. Subtract the values: 230-140 = 90.

The distance from the shortest height (140 cm) and tallest height (230 cm) is 90 cm, which is the range.

Unlike the previous two statements, choice C is not correct. Each bar represents a different interval. There are 6 bars, so there are 6 intervals (not 7).

Choice D however, is correct. Focus on any single bar. Look at where its left and right endpoints are located. The first bar for instance starts at x = 140 and ends at x = 155. The gap is 155-140 = 15 units wide.

hi! i think the answer is 1/2 : )

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
