Answer:
Refer the attached graph.
Step-by-step explanation:
Given : Time (h) Distance (km) able displaying Time in hours in one column and Distance in kilometers in the other. The time column contains 1, 3, 6, and 9. The distance column contains 2, 6, 12, and 18.
To plot : The points on the coordinate plane.
Solution :
Time is independent variable so it is taken on x-axis.
Distance is taken on y-axis.
x y
1 2
3 6
6 12
9 18
When we plot these points in the coordinate plane, we get a linear equation.
The linear equation form is
Refer the attached graph.
The percent of the increase is
I is the increasing value
N is the new value
O is the original value
The price of the cooler is $28.50, then
O = 28.50
The selling price of the cooler is $40.76, then
N = 40.76
We will substitute them in the rule above to find I
Let us calculate it
I = 43.0175 %
Round it to the nearest percent
I = 43%
The answer is D

Answer: 9.70%
Step-by-step explanation:
The formula to find the percentage error is given by :-
Given : Actual mass of zinc oxide used by pharmacist = 28.35 g
Estimated mass of zinc oxide used by pharmacist =31.1 g
Now,
i.e.
i.e.
Hence, the percentage of error on the basis of the desired quantity.= 9.70%
Step-by-step explanation:
D. Both charges must be different.
Because, like charges repel each other and different charges attract each other.
