First, move the constant (+9) to the right side of the equation and change the sign:
-10p=12-9

Then, subtract 12 by 9 to get 3:
-10p=3

Finally, divide both sides of the equation by -10:
p= -3/10 or -0.3

Your answer is
p= -3/10 OR
p= -0.3

 If length AM = AK then it is isosceles.

M(-1,-6), A(-4,5)

AM=((5-(-6))²+(-4-(-1)))^(1/2)=11.401

A(-4,5) and K(5,-2)

AK=((-2-5)²+(5+4)²)^(1/2)=11.401

so the triangle is isosceles.

Which of the following relations has an inverse that is not a function?
sertanlavr [38]

Answer:

Option B is correct.

The relation which has an inverse that is not a function is :(1, 2), (1, 3), (4, 3)

Step-by-step explanation:

Inverse of a function is the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function.

Let f(x) ={(1, 2), (1, 3), (4, 3)}

To find the inverse:

Inverse of f(x)=g(x)= {(2, 1), (3, 1), (3, 4)}

Function states that a relation in which each input value has only one output value.

Since, g(x) is not a function because the input 3 has multiple output values,.

Therefore, the only relation which has an inverse that is not a function is :(1, 2), (1, 3), (4, 3)

On a particular production line, the likelihood that a light bulb is defective is 10%. seven light bulbs are randomly selected.
amid [387]

Answer:

0.9995

Step-by-step explanation:

10% = 0.10

1 - 0.10 = 0.9

n = number of light bulbs = 7

we calculate this using binomial distribution.

p(x) = nCx × p^x(1-p)^n-x

our question says at most 4 is defective

= (7C0 × 0.1⁰ × 0.9⁷) + (7C1 × 0.1¹ × 0.9⁶) + (7C2 × 0.1² × 0.9⁵) + (7C3 × 0.1³ × 0.9⁴) + (7C4 × 0.1⁴ × 0.9³)

= 0.478 + 0.372 + 0.1239 + 0.023 + 0.0026

= 0.9995

we have 0.9995 probability that at most 4 light bulbs are defective.
