Answer:
The percent attendance for that semester was 30%.
Step-by-step explanation:
In this problem, out of 190 students, only 57 students had perfect attendance. When a question says something like this, then it means that you are going to use division. You are going to divide 57 by 190.
57 ÷ 190 = 0.3
Now, multiply 0.3 by 100 to get the percentage.
0.3 * 100 = 30
So, the percentage of the perfect attendance is 30%.
Step-by-step explanation:
the point being that a quadratic equation has 2 x-intercepts (or solutions of x for y = 0).
the advantage of this nice form the equation is written in is, that we see immediately both conditions, when y can be 0 : one of the bracket expressions must be 0.
so, the point (1, 0) covers (x-1).
we get the solution for (x-n), when we consider that such a quadratic function is simply a parabola and is symmetric around its vertex point.
the x value of the vertex (-2) tells us, that it is 3 units on the left side of the (1, 0) x-intercept point.
due to the symmetry of the curve the second x-intercept point must be even further to the left with additional 3 units distance in x direction.
so, -2 - 3 = -5
and A is the correct answer option.
Answer:
1/2, 1/10, and 1/14 s the answer.
Step-by-step explanation:
The first set of numbers are integers, the second set is whole numbers, the fourth set is imaginary numbers, and the fifth set is irrational numbers. The third set is rational because it can be written as a fracton but not integers because they aren't whole numbers or their opposites.
Answer:
Step-by-step explanation:
Question :
Given:
varies directly with 
when 
To find value of when 
Solution:
From the given data we have:
∝
Thus, we have:
where 
is the constant of proportionality.
<em>We can find the value of by plugging in the given values.</em>
when
Dividing both sides by 2.
∴ 
So, the equation to find when will be:
Thus, when
