Answer:
1.5
Step-by-step explanation:
Attached to this answer is the diagram of the box plot described in the question, and the means from the plot are calculated thus;
Students; no. of siblings
student 0 2
student 1 4
student 2 7
student 3 5
student 4 2
Total 20
Mean no. of siblings = (total number of siblings) ÷ (total number of students)
Note that number of students here are the once that had at least one sibling, others without siblings are not used in the calculation, hence 5 students (student-0 to student-4) make up total number of students, while the remaining 4 students (student-4 to student-9) are disregarded.
Therefore, mean = 20 ÷ 5 = 4 siblings.
Answer:
60 days
Step-by-step explanation:
Let's call h the daily dose of medication that a diabetic person should administer.
We know that:
h = 0.0005 L/day
We know that 0.03 liters is what the social institution provides.
Then we can raise the following equation:
hx = 0.03
Where x is the number of days
So:
x = 60 days.
After 60 days you will have to return for more doses
Answer:
y = 4x
Step-by-step explanation:
Points on the graph:
- (-4, -16), (0,0), (4, 16)
<u>Slope intercept form:</u>
<u>Working out slope using two of the points:</u>
- m= (y2-y1)/(x2-x1)
- m= (0- (-16))/(0- (-4))
- m= 16/4
- m= 4
<u>The equation is now:</u>
<u>Using one of the points to find b:</u>
- -16 = 4*(-4) +b
- -16 = -16 + b
- b = 0
<u>So the final form is:</u>
<u>Correct answer choice is</u> the last one
