Answer:

P(A or B) = 1.16

Step-by-step explanation:

Given probability:

Probability of event A = P(A) = 0.46

Probability of event B = P(B) = 0.7

P(A and B) = 0.43

Find:

P(A or B)

Computation:

If A is an incident and B is a separate event, P(A or B) is the possibility of either A, B, or both events occurring.

P(A or B) = P(A) + P(B)

P(A or B) = 0.46 + 0.7

P(A or B) = 1.16

What is the arc length of a semicircle with a radius of 11?

kap26 [50]

Answer:

The arc length of the semicircle is: $11 \pi$ , which is approximately 34.5575

Step-by-step explanation:

Recall that the length of a circumference of radius R is given by:

$length = 2\,\pi \,R$

therefore, the arc length of a semicircle (half of the circle) would be given by half of the previous expression:

$length\,\,of \,\,semicircle= \pi\,R$

So, in our particular case of radius 11, the formula for the arc length of the semicircle becomes:

$length\,\,of \,\,semicircle= \pi\,R\\length\,\,of \,\,semicircle= 11 \pi\\length\,\,of \,\,semicircle= 34.5575$

У = 4х – 1 у = 2х – 5 How do you solve this, by using substitution?!

solmaris [256]

Answer:

x = -2, y = -9

Step-by-step explanation:

You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.

y = 2x -5 will become

4x - 1 = 2x - 5

Add 5 to both sides

4x + 4 = 2x

Subtract 4x from both sides

4 = -2x

Divide both sides by -2

-2 = x

Now we plug this number into an equation to find y.

y = 4x - 1 becomes

y = 4(-2) - 1

Simplifying it, we have:

y = -8 - 1

y = -9
