The probability of selecting one student who is both from math and science is 1/10
There are the total number of student = 300
Out of which,the number of students who are only in Maths = 120
The number of students who are only in Science = 50 and the students who are not from any subject = 100
<h3>What is the formula for the
total students?</h3>
Total no of students=science student+math students +none
Therefore,the number of student who are from both math and science = Total student - Math student (only) - science student (only) - None
= 300 - 120 - 50 - 100
= 30
That is, there are 30 students who are both from science and math,
Thus, the probability of selecting one student who is both from math and science = 30/300 = 1/10

The negative number would most likely be -19/2
let the negative number be x,
3 less than twice that negative number would be (2x-3)
hence,
equation form
x multiply by (2x-3) equals to 209
it would result in equation
2x^2-3x=209
2x^2-3x-209=0
hence using quadratic eqn
x=11 ( rej since qn stated x is a negative number)
x=-19/2
Answer:
300 ft
Step-by-step explanation:
Given that a city planner wants to build a ramp onto a highway. The vertical distance that the ramp goes up is 160ft. The length of the ramp is 340ft and represents the hypotenuse of a right triangle.
i.e. the triangle formed is a right one with hypotenuse 340 ft and one side 160ft. The other side is the horizontal distance the ramp will cover say x
Then by Pythagorean theorem we get
Thus horizontal distance the ramp will cover = 300 ft.
