1. Using the chart of student favorite color, create a nice and neat bar graph to show the data.

2. Using the chart of student favorite color, create a pie graph to show the data. (Shows %s)

3. Which color is the most popular? The least?

4. What % (to the nearest hundredth) of students say red as their favorite color?

5. What is the difference in % (to the nearest hundredth) of students who like pink versus black?
Favorite Color Number of Students
Red 14
Blue 22
Green 17
Black 3
Pink 4

8. Which month had the highest temperature? The lowest?

9. What is the temperature difference for February and May?

10. How many months have a temperature higher than 30 degrees Celsius?

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

a.for lorena 14 hours makes $126   for 16 hours she makes 144

for julie 6 hours makes $72 for 21 hours its $252

b. julie makes more money than lorena julie makes $12 an hour and lorena makes $9  

.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
