Use the equation .8x + x = 252
x is the number, and .8 is the decimal equivalent of 80%.
1.8x = 252
x = 140
Ive done this problem but with a different velocity. Just plug in the numbers/information they give you into the equation and solve for t. The value for t will be your answer
Answer:
36
Step-by-step explanation:
We must determine the x and y intercepts of the parabola:
When y=0, x=0 or x=10
WE know that the point of the triangle base is x and x+8. We can substitute this into the parabola equation because the endpoints are on the parabola.
f(x+8)
f(x+8)
f(x)=f(x+8)
solve for x
Therefore the heigh is f(1):
The area of the triangle is 1/2 base x height:
In the given table, we can calculate the sample space of the problem. The sample space includes all the categories of the people involved. The sample space is the total of the numbers given. This is equal to 300. The probability ofgetting someone who tests positive, given that he or she had the disease is 141/300 equal to 47 percent
