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.

Solve for x thanks .
OleMash [197]

Answer:

x = 3.87

Step-by-step explanation:

Using the right angle altitude theorem, we know that all three triangles are congruent, so the lengths of corresponding sides of the triangles are in proportion..

AD/DB = DB/DC

15/x = x/1

x² = 15

x = √15

x = 3.87

A chemist needs 130 milliliters of a 47% solution but has only 35% and 87% solutions available. Find how many milliliters of eac
choli [55]

Answer: Amount of 35% solution required = 100 milliliters

Amount of 87% solution required  = 30 milliliters

Step-by-step explanation:

Given: Total solution required =  130 milliliters

Let x = Amount of 35% solution (in milliliters).

Then, Amount of 87% solution required = 130 - x

As per given,

Concentration = 0.35x +0.87(130-x)=0.47(130)

0.35x +113.1-0.87x=61.1\\\\\Rightarrow\ -0.87x+0.35x=61.1-113.1\\\\\Rightarrow\ -0.52 x= -52\\\\\Rightarrow\ x=\dfrac{52}{0.52}=100

Hence, Amount of 35% solution required = 100 milliliters

Amount of 87% solution required  = 130-100 milliliters =30 milliliters
