<h2>Answer:</h2>

The formula that is used to calculate the probability of independent events A and B are:

                        D. P(A and B)=P(A)·P(B)

<h2>Step-by-step explanation:</h2>

Independent events--

Two events A and B are said to be independent if the happening of one event do not affect the happening of the other event.

For example-- The probability of getting two heads on rolling a die two times.

Hence, the formula that calculate the probability of independent events A and B is given by:

        P(A\bigcap B)=P(A)\cdot P(B)

SCORPION-xisa [38]

3.65 e8

Step-by-step explanation:

The scientific notation e mean ‘10 raised to a particular power’. Therefore e8 is equivalent to 10 ^ 8.

We count the number of tens to the decimal point. In this case;

365000000

3.65000000

The decimal is <u>8</u><u> place values </u>from the right (since this is a whole number)

The size of angle aob is equal to 132 degrees and the size of angle cod is equal to 141 degrees. find the size of angle dob.
Varvara68 [4.7K]

angle AOB = 132 and is also the sum of angles AOD and DOB. Hence 
angle AOD + angle DOB = 132°    ---> 1 

angle COD = 141 and is also the sum of angles COB and BOD. Hence 
angle COB + angle DOB = 141°    ---> 2

Now we add the left sides together and the right sides of equations 1 and 2 together to form a new equation. 

angle AOD + angle DOB + angle COB + angle DOB = 132 + 141       ---> 3 

We should also note that: 
angle AOD + angle DOB + angle COB = 180° 

Therefore substituting angle AOD + angle DOB + angle COB in equation 3 by 180 and solving for angle DOB:
180 + angle DOB = 132 + 141 
angle DOB = 273 - 180 = 93°

Factor.<br><br> 10x^5 − 16x^4 + 4x^2
Licemer1 [7]
We have to find the GCD between 10, 16 and 4 and between x^5, x^4 and x^2

GCD (10,16,4) = 2
GCD (x^5,x^4,x^2) = x^2

So we divide all terms for 2x^2

Final result: 2x^2(5x^3-8x^2+2)
