Step-by-step explanation:
thats if your solving for x if not to math w l ay
Answer:
The cost for 20 students would be $120
Step-by-step explanation:
We know that 4x5=20 therefore we will multiply 30x4 which will give us 120.
Our final answer would be $120
Based on the data, the most likely correlation coefficient would be -1.
The slope between 20 and 30 days is -1, and it represents the change in the surface area of the lake per day.
The data represents correlation, not causation.
Since the data would form a perfectly straight line through the points, the correlation coefficient would be -1 for a perfect decreasing fit.
To find the slope, find the change in the surface area between those days, the change in the days, and write it as surface area/days: 80-90=-10; 30-20=10; -10/10=-1
This is not causation because there could be lurking variables we cannot see.
The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.
Area of Square + 4*Area of Triangle = SA
Area of Square:
2^2=4
Area of Triangle:
0.5*2*3=3
SA=4+4*3
SA=16 meters squared
1) To write 0.259 as a fraction let's firstly rewrite as

2) Count the digits the dot has gone to the left. Each digit to the left means divided by ten. Like this:
3) Since it starts with a zero then it can't be a Mixed number. So it is an improper fraction. No further simplification could be done.
