7. i would guess 95-100 people were surveyed. the way you estimate this is by adding the number of students in each category. ex. about 3 in the first bar, about 9 in the next
8. no, you could not list the exact height because the data given only shows the number of students in between 75-80, not their actual height.
Answer:25 hope this helps
Step-by-step explanation:
Answer:
x=18 degrees
Step-by-step explanation:
since this is a triangle, you know that the three angles added up equal 180 degrees. since it is a right triangle, 25+3x+11=90 (the right angle=90). then you just solve for x: 3x=54, x=18
Answer:
Zero solutions.
Step-by-step explanation:
4x - 8 - 4x = 9
-8 = 9
No solutions.
Add 3/7 to the equation for x= 4 3/7 which is your final answer. X is 4 3/7.
