A 48-year-old person is 4.2048 × 105 hours old. Write this number in standard form.

1 answer:

6 0

4.2048 x 105 = 441.504

the standard form should be between 1 and 9 so the decimal point should be after the first digit (4)

it would look like this 4.41504 x 10 to the power of 2 because it moved back two places. hope it makes sense? (:

Photo and Video Sharing. Photos and videos have become an important part of the online social experience, with more than half of

love history [14]

Answer: 0.923

Step-by-step explanation:

Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves.

Pew Research Center finds that

P(A)=0.52 P(b)=0.26, and P(A or B)=0.54.

To find : P(A|B)

Since , $\text{P(A or B)=P(A+P(B)-P(A and B)}$

i.e. $\text{P(A and B)=P(A)+P(B)-P(A or B)}$

$\text{P(A and B)=}0.52+0.26-0.54=0.24$

Now, using conditional probability formula ,

$P(A|B)=\dfrac{\text{P(A and B)}}{\text{P(B)}}\\\\=\dfrac{0.24}{0.26}=0.923076923077\approx0.923$

Hence, the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves = 0.923
