Answer: 0.05

Step-by-step explanation:

Given : Interval for uniform distribution : [46.0 minutes, 56.0 minutes]

The probability density function will be :-

f(x)=\dfrac{1}{56-46}=\dfrac{1}{10}=0.1\ \ , 46

The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-

P(50.75

Hence, the probability that a given class period runs between 50.75 and 51.25 minutes = 0.05

Julian fully simplifies this polynomial and then writes it in standard form. 4x2y2 – 2y4 – 8xy3 + 9x3y + 6y4 – 2xy3 – 3x4 + x2y2

Given that the last term is -3x^4, the polynomila is ordered in descending order of the exponent of x. Then, the first term is that where y is with the highest exponent, that is y^4

Simplify the terms with y^4: -2y^4 + 6y^4 = 4y^4

Then the first term is 4y^4

Which choices name a chord of circle F? Choose all answers that are correct. A. AD B. BE C. CF D. DF?
Natalka [10]
I have encountered this problem before. The figure gave out 3 chords, 2 of which are diameters, and 1 radius.

A chord is a line segment that joins any two points on a circle. 

A diameter is the longest chord on a circle. It originates at one side of the circle, passes through the middle point of the circle, and end on another side of the circle.

The chords in the figure area: AD, BE, and DE. AD and BE are diameters, they pass through F.

Among the choices: A.) AD and B.) BE are the chords.

CF and DF are radii. They only end up in the middle point of the circle.
