It would be B because you have to divide both sides by -2 to isolate the y !

-2y = 4(0) +8
-2y = 0 +8
( -2y = 8 ) /-2
y = -4
The answer is B. (0, -4).

A six-sided number cube is rolled twice.

Kitty [74]

Answer:

1/6

Step-by-step explanation:

Probability is a chance of an event taking place.

Probability = (favorable outcome)/(total outcome)

There are 3 even sides in a dice.

P(even) = 3/6 = 1/2

There are 2 numbers that are greater than 4 in a dice.

P(x>4) = 2/6 = 1/3

P(even and x>4) = 1/2 × 1/3 = 1/6

What is the initial value and rate of change if

Liula [17]

Answer:

Rate of change = -30

Initial value = 400

Step-by-step explanation:

Write the equation of the linear function representing this situation. Let

x = number of weeks Gandalf is spending money

y = amount of quibbles left in his account.

Gandalf has 400 quibbles in his account. This means, $b=400$ is the initial value of quibbles Gandalf had in his account

He spends 30 quibbles each week, this means, that he spends 30x quibbles in x weeks and the amount left in his account is

$y=400-30x$

Therefore, the slope is $-30$ and this is the rate of change (negative because the amount of money in his account decreases each week)

Let x be a continuous random variable having cumulative distribution function f. define the ran- dom variable y by y =f(x). show

DochEvi [55]

Given that F is a distribution function then it is going to be said to be non decreasing.

<h3>How to define the random variable</h3>

Let Y = F(x)

Then we have a distribution function that we can define to be

Gy(Y) = P(Y≤y) = P[F(X)≤y]

= P[x≤F⁻¹(y)]

The inverse is said to exist given that the value F is non decreasing and it is also said to be continuous.

Such that Gy(Y) = F[F⁻¹(y)]

then we have to see f to be the distribution of x

Gy(Y) = y

The PDF of Y is denoted as Y = F(X)

then we would have

d/dy [Gy(Y)] = 1

Given that F is a df, then the value of the distribution function would always be 0, 1.

gy(y) would then have to be 1

0 ≤ y ≤ 1

This tells us that F(X) is a uniform variate of 0,1.

The range is subtracting the lowest number in the data set from the highest number in the data set.

25.

A. 6.5-0 = 6.5

B. 6 - 0.5 = 5.5

C. 6.5 - 0.5 = 6

D. 6.5 - 0.5 = 6

26.

Highest time: 26:10

Lowest time: 20:58

Range = 26:10 - 20:58 = 5 minutes, 12 seconds
