0.25
0.75
1.00

Answers

Answer 1
Answer:

The probability that she will have two boys will be 0.25 .

What is probability ?

Probability is the ratio of number of favorable outcome to the total number of outcome.

Probability =(Number\ of\ favorable\ outcome)/(Total\ Number\ of\ outcome)

We have,

Boy-Boy =1

Girl-Girl  =1

Boy-Girl =1

Girl-Boy =1

So,

Total number of outcome =4

And number of favorable outcome of Boy-Boy =1

So,

Probability =(Number\ of\ favorable\ outcome)/(Total\ Number\ of\ outcome)

Probability (Boy-Boy) =(1)/(4)=0.25

Hence, we can say that the probability that she will have two boys will be 0.25 .

HELP EXPLAIN STEP BY STEP In a circle whose radius is 8, the length of an arc of the circle is 2π. In radians, what is the measure of the central angle subtended by the arc?

Answers

Answer:

(\pi)/(4)

Step-by-step explanation:

We have been given that the radius of a circle is 8 and the length of an arc of the circle is 2π. We are asked to find the measure of central angle subtended by the arc in radians.

We know that the arc length of a circle is equal to central angle times the radius of circle.

\text{ Arc length}=\theta\cdot r

2\pi =\theta\cdot 8

(2\pi)/(8)=(\theta\cdot 8)/(8)

(\pi)/(4)=\theta

Therefore, the measure of central angle is (\pi)/(4) radians.
arc length = rθ    [r = radius of the circle, θ = central angle in radians]  ⇒

2π = 8*θ   ⇒   θ = 2π/8 = π/4

solve the equations

Answers

Subtract the second equation from double the first equation:

2x+6y-2x-(-4y)=0

10y=0

Therefore, y=0.  Substituting this into the first equation, we see that:

x+3(0)=3

x=3

Therefore, x=3.  The solution to this system is x=3, y=0, or (3, 0).
so divide the second equation by 2
x-2y=3
the first equation is
x+3y=3
subsitute
3=3 so therefor
x-2y=x+3y
subtract x from both sides
-2y=3y

add 2y to both sides
0=5y
ofviously y=0 so subsitute
x-2y=3
x-(2)0=3
x-0=3
x=3

x=3
y=0
