A friend claims that it will rain today with probability 30% and tomorrow with probability four times as great as today. Which o

f the following is CORRECT?
The claim can be true because it is more likely to rain tomorrow if we have rain today.
The claim cannot be true because raining tomorrow is not guaranteed. The claim can be true because it is possible to have rain tomorrow.
The claim cannot be true because any probability is between 0 and 1.

Answer:

  The claim cannot be true because any probability is between 0 and 1.

Step-by-step explanation:

4 times 0.30 is 1.20, a value that cannot be a probability. Any probability will be between 0 and 1 (inclusive).

The claim cannot be true because any probability is between 0 and 1.

Answer:

Step-by-step explanation:

The answer would be:

The claim cannot be true because any probability is between 0 and 1.

Because we can only be 100% certain of something or less.

If he's saying that tomorrow you have 4 times the probability of today, which is 30%, that would be 120%. But you can't be 120% sure that it will rain.

The correct answer is C. Let’s break this down with the distributive property.

5(6x+6)

30x+30

5(9-x)

45-5x

Now add and subtract like terms.
30x-5x=25x

30+45=75

Put the remaining numbers together.
25x+75 and there you go.

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = 3x2 − 2x + 1, [0, 2] Yes, it do
expeople1 [14]

Answer:

Yes , function is continuous in [0,2] and is differentiable (0,2) since polynomial function are continuous and differentiable

Step-by-step explanation:

We are given the Function

f(x) =3x^2 -2x +1

The two basic hypothesis of the mean valued theorem are

  • The function should be continuous in [0,2]
  • The function should be differentiable in (1,2)

upon checking the condition stated above on the given function

f(x) is continuous in the interval [0,2] as the functions is quadratic and we  can conclude that from its graph

also the f(x) is differentiable in (0,2)

f'(x) = 6x - 2

Now the function satisfies both the conditions

so applying MVT

6x-2 = f(2) - f(0) / 2-0

6x-2 = 9 - 1 /2

6x-2 = 4

6x=6

x=1

so this is the tangent line for this given function.
