To draw a histogram, you need two axes. The horizontal axis is the day and the vertical axis is the number of text messages. For the first day, there are 20 text messages. This is represented by a bar starting from the horizontal axis labeled Day 1 going up to the point where the vertical axis indicates 20 text messages. This is done for the rest of the data. Afterwards, a line is drawn from the vertex of the axes connected to the top of the first bar. Then from the top of the first bar, a line connects it to the top of the next bar. This is done for all the bars before producing a histogram.
Answer: 10+12+6+4=32
100/32=3.125
12x3.125= 37.5 percent of the people that were surveyed chose piano.
Answer:
20%
Step-by-step explanation:
- Start by changing the fraction to a decimal by diving the numerator by the denominator ( 1 divided by 5 ). That equals 0.2 .
- Change the decimal to a percent by multiplying it by 100% , or moving the decimal two places. That gives you 20% .
A rational number is any number that can be written in a/b form (like a fraction). So it just can't be a repeating decimal like how pie goes on forever. So let's see. 8.05 could work. Since you could write that as 8.05 over 1 (8.05/1)
