Answer: 19 miles

Step-by-step explanation:

Distance = speed × time

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. This means that the distance covered on her way to the train station is

0.5 × 10 = 5 miles

Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 28 mph. Distance covered by the train is

0.5 × 28 = 14 miles

Therefore, the distance that Kristen travels to work is

14 + 5 = 19 miles

Ierofanga [76]

Answer:

f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)

Step-by-step explanation:

Given

The range of values is given as {0,1,2,3,4}

Because any computer can fail.

Given that the failure of the computers are independent and

The probability of failure is given as 0.0005.

Cumulative Distribution Function is the the probability that a random variable is less than or equal to a specific value

So, we'll take the binomial effect into consideration.

It is given as

f(x) = P(X ≤ x) = 4Cx * 0.0005^x * (1 - 0.0005)^(4 - x)

f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)

What the answer to 3(x-4)=2(-2x+1)
lidiya [134]

Answer:x = 2

Step-by-step explanation:

Simplifying

3(x + -4) = 2(-2x + 1)

Reorder the terms:

3(-4 + x) = 2(-2x + 1)

(-4 * 3 + x * 3) = 2(-2x + 1)

(-12 + 3x) = 2(-2x + 1)

Reorder the terms:

-12 + 3x = 2(1 + -2x)

-12 + 3x = (1 * 2 + -2x * 2)

-12 + 3x = (2 + -4x)

Solving

-12 + 3x = 2 + -4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4x' to each side of the equation.

-12 + 3x + 4x = 2 + -4x + 4x

Combine like terms: 3x + 4x = 7x

-12 + 7x = 2 + -4x + 4x

Combine like terms: -4x + 4x = 0

-12 + 7x = 2 + 0

-12 + 7x = 2

Add '12' to each side of the equation.

-12 + 12 + 7x = 2 + 12

Combine like terms: -12 + 12 = 0

0 + 7x = 2 + 12

7x = 2 + 12

Combine like terms: 2 + 12 = 14

7x = 14

Divide each side by '7'.

x = 2

Simplifying

x = 2
