Answer:

9 days

Step-by-step explanation:

Experimental probability is the number of times an event occurs divided by the total number of trials of the event.

We know the experimental probability, based on past data, that rain will fall 20% chance.

So, one can expect, that in the next 45 days, rain will fall 20% of the days, according to our experimental probability.

First, we find decimal equivalent of 20%. We divide by 100:

20% = 20/100 = 0.2

Now we multiply this with the number of days:

0.2 * 45 = 9

Thus,

One can expect it to rain 9 days

Find x<br> (4+25)<br> (6x+20)<br> (3x+25)
ASHA 777 [7]

Answer:

x = 15

Step-by-step explanation:

the opposite angle of a cyclic quadrilateral sum to 180° , then

6x + 20 + 3x + 25 = 180

9x + 45 = 180 ( subtract 45 from both sides )

9x = 135 ( divide both sides by 9 )

x = 15

7) 4b2 + 8b + 7 = 4<br> What the answer
Anit [1.1K]

4b² + 8b + 3 = 0

4b² + 2b + 6b + 3 = 0

2b(2b + 1) + 3(2b + 1) = 0

(2b + 3)(2b + 1) = 0

b = -1/2 or b = -3/2

Solve for b<br> 2(-2b+3)=9
Alexxx [7]

Answer:

b=-3/4 or b=-0.75

Step-by-step explanation:

2(-2b+3)=9

2b+3=\cfrac{9}{2}

-2b=\cfrac{9}{3} -3

-2b=\cfrac{3}{2}

b=-\cfrac{\frac{3}{2} }{2}

b=-\cfrac{3}{2\times 2}

b=-\cfrac{3}{4}

Hope it helps! :)
