Answer:
=45 b/c all we have to do is subtract the higher number to the lowest number.
It's a Quadratic that doesn't have any real roots as the parabola doesn't cross the x-axis.
For graphing:
If you're familiar with the parabola of y=x^2, then you could graph that but just translate it upwards by +4 on the y such that f(x)+4 will be equal to it.
If you aren't, then we know the y-intercept is 4, and that's also the point of the minimum point of the curve. If I were you, I'd write a table of some of the integer values:
x y
-2 8
-1 5
0 4
1 5
2 8
The value of y is the same for x and -x as anything squared is positive.This means that there is a line of symmetry in the y-axis.
This then makes it much easier to graph, simply place these points on the graph and make sure the curve is exponential. This means the gradient (steepness) gets greater the bigger the value of x.
Answer: Saturn. Saturn's perhelion is at 9.50AU, aphelion at 10.12AU.
Answer:
P(2.5≤X≤4) = 0,3125
Step-by-step explanation:
We know that the area under the curve of ANY probability distribution should not be greater than 1.
In this case, we now that 4P = 1, therefore, P=1/4. Where 'P' represents the height of the rectangle that represents the probability distribution.
The probability of P(2.5≤X≤4) will be given by the area of the following rectangle:
(4 - 2.5) × 1,5 = 0,3125
Therefore, P(2.5≤X≤4) = 0,3125
UM i need more details sorry but i dont know it
