I will mark brainliest!!
sladkih [1.3K]

Answer:

C. Events E and A are independent

Step-by-step explanation:

we will verify each options

(a)

We can use independent events formula

P(B∩C)=P(B)*P(C)

we are given

P(B)=0.4

P(C)=0.25

P(B∩C)=0.05

now, we can plug these values into formula

and we get

0.05=0.4*0.25

0.05=0.1

we can see that left side is not equal to right side

so, this is FALSE

(b)

We can use independent events formula

P(D∩A)=P(D)*P(A)

we are given

P(D)=0.25

P(A)=0.6

P(D∩A)=0.1

now, we can plug these values into formula

and we get

0.1=0.25*0.6

0.1=0.15

we can see that left side is not equal to right side

so, this is FALSE

(c)

We can use independent events formula

P(E∩A)=P(E)*P(A)

we are given

P(E)=0.5

P(A)=0.6

P(E∩A)=0.3

now, we can plug these values into formula

and we get

0.3=0.5*0.6

0.3=0.3

we can see that both sides are equal

so, this is TRUE

(d)

We can use independent events formula

P(D∩B)=P(D)*P(B)

we are given

P(D)=0.25

P(B)=0.4

P(D∩A)=0.15

now, we can plug these values into formula

and we get

0.15=0.25*0.4

0.15=0.1

we can see that left side is not equal to right side

so, this is FALSE

Write an inequality for the given statement: 4 times the sum of a number and 3 is at least 28.
IrinaK [193]
The answer to the question is letter C. 4(x + 3). The expression means that the sum of x and 3 is multiplied by 4. This expression should be equal or greater than 28. All the other choices do not satisfy the inequality.

Which equation represents a line which is parallel to the line x-<br> 8y = 48?
dolphi86 [110]

Answer:

y = 1/8x

Step-by-step explanation:

<h3>REMEBER: When the slopes are two lines are equal, they're parallel.</h3>

Given Equation:

  • x - 8y = 48 ---> This equation is in standard form.

⇒ -8y = -1x + 48

⇒ y = 1/8x + 6

As a result, the equation of the parallal line to the given equation x - 8y = 48 is:

⇒ y = 1/8x
