Answer:
2nd option is the correct one
Answer:
50
Step-by-step explanation:
Fastest method for calculating 34 is 68 percent of what number. Assume the unknown value is 'Y' 34 = 68% x Y. 34 = 68 / 100 x Y Multiplying both sides by 100 and dividing both sides of the equation by 68 we will arrive at: Y = 3 x 100 / 68. Y = 50%. Answer: 34 is 68 percent of 50

The roots are 
, which is given by option C.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
In this question, we have that:
Which is a quadratic equation with 
. So
So the roots are , which is given by option C.
When looking at a graph, discrete data will have all the pints connected so it will look something like the 1st picture that I provided. Something that is discrete can not be broken down into decimals or fractions so we usually say discrete things can be counted.
On the other hand, continuous data is usually things that we associate with measuring. These types of graph will have dots all over them and they can have fractions and decimals in them.
