A race car travels at a speed of 230 miles per hour. The race track on which the car is competing is 400 miles long. About how l
olga nikolaevna [1]
To solve for this we will be using the formula S = D/T

S = Speed
D = Distance 
T = Time

First we need to re-arrange this formula to solve for time

T= D/S

T = 400/230

T=1.74 hours

.74 hours is close enough to .75 that we can say it is 45 minutes

So it is 1 hour and 45 minutes

The valid probability distributions are the ones in options C and D.

<h3>Which of the following are valid probability distributions?</h3>

For discrete random variables with probabilities p₁, p₂, ..., pₙ, there are two rules:

  • All of these probabilities are numbers between 0 and 1.
  • p₁ + p₂ + ... + pₙ = 1.

So, for the first rule we can discard the first option, where we have negative probabilities.

To check the other 4 options, just add the probabilities and see if the addition gives 1.

The options that add up to 1 are C and D, so these two are the correct options.

D: 1/5 + 1/10 + 1/10 + 1/10 + 1/5 + 1/10 + 1/10 + 1/10 = 1

C: 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 1

Can someone please help me find the measure of the exterior angle.
natta225 [31]

Answer:

X=128°

Step-by-step explanation:

Because an exterior angle of a triangle is equal to of the two opposite interior angle.

The sum of the exterior and interior angle is equal to 180°

In this case the part marked red = 90° because is a right angled triangle.

90+38=128

180- 128=52

180- 52=128

x=128.
