Is it possible for an event to have a probability of 1? Explain.

Answers

An event that is certain to happen has a probability of 1(So yes an event can have a probability of 1).
 An event that cannot possibly happen has a probability of zero. (examples  below)
 
--If it is Thursday, the probability that tomorrow is Friday is certain, therefore the probability is 1.
--If you are sixteen, the probability of you turning seventeen on your next birthday is 1. It's a certain event.

Find the equation of the circle that passes through the origin and has its center at (-3,-4).

Answers

If the center is at (-3, -4) and the origin is on the circle, then the radius
of the circle is the distance between the origin and (-3, -4).

R² = (-3)² + (-4)²
R² =  9    +  16
R² =      25
R = 5

The equation of the circle is [  (x + 3)² + (y + 4)² = 25 ].
equation\ of\ the\ circle:(x-a)^2+(y-b)^2=r^2\n\n(a;\ b)\ is\ a\ cener\ of\ the\ circle\n\n(a;\ b)=(-3;-4)\n\nr-radius\ of\ the\ circle\n\nr=√((-3)^2+(-4)^2)=√(9+16)=√(25)=5\n\nAnswer:(x+3)^2+(y+4)^2=5^2\to(x+3)^2+(y+4)^2=25

Calculate the average velocity or a race car when an object travels on track and passes the 300m mark at 10 seconds and the 1100m mark at 24.5 seconds. rounded to the nearest whole number.

Answers

Answer:

55 m/s

Step-by-step explanation:

average velocity=(1100-300)/(24.5-10) =(800)/(14.5)=(1600)/(29)  \approx 55 ~m/s

Factor completely 14bx2 − 7x3 − 4b + 2x.(2b + x)(7x2 + 2)

(2b − x)(7x2 − 2)

(2b + x)(7x2 − 2)

Prime

Answers

Answer:

(2b-x)(7x^2-2)

Step-by-step explanation:

We have to factor the expression 14bx^2-7x^3-4b+2x

We apply the method of grouping to factor it.

Make groups

(14bx^2-7x^3)+(-4b+2x)

Take GCF

7x^2(2b-x)-2(2b+x)

Finally, factored out the common factor

(2b-x)(7x^2-2)

The factored form of the given expression is

(2b-x)(7x^2-2)

hello,

14bx²-7x^3-4b+2x= -7x^3+14bx²+2x-4b
=-7x²(x-2)+2(x-2b)
=(x-2b)(-7x²+2)
=(2b-x)(7x²-2)
