Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

P(A|B)=\frac{P(Aand B)}{P(B)}

now, we can plug values

P(A|B)=\frac{0.15}{0.9}

P(A|B)=0.16666

but we have

P(A)=0.5

we can see that both are not equal

P(A|B)\neq P(A)

so, A and B are not independent

so, option-C........Answer

Sav [38]

Answer:

6 kg/m

Step-by-step explanation:

mass m = 3x^2.

rho ρ= dm/dx =6x

ρ(1) =6 Kg/m

linear density is the derivative of mass (m)  with respect to position(x)

that is how fast is the mass changing at that position.

In circle O, what is mArc A E?
posledela

Answer:

Option (3). 120° will be the answer.

Step-by-step explanation:

By using the theorem of secants intersecting externally,

Measure of angle formed by two secants, from a point outside the circle is half the difference of the measures of the intercepted arcs.

m∠C = \frac{1}{2}(m\widehat{AE}-m\widehat{BD})

36° = \frac{1}{2}(m\widehat{AE}-48)

72° = m\widehat{AE}-48°

m\widehat{AE} = 72 + 48

m\widehat{AE} = 120°

Therefore, Option (3) is the answer.

The length of a rctangle is to more than the
hram777 [196]

Answer:

  19 m

Step-by-step explanation:

The width is 2 less than the length, so the perimeter is ...

  P = 2(L +W)

  72 = 2(L +(L -2))

  76 = 4L . . . . . . . . add 4

  19 = L

The length of the rectangle is 19 meters.
