Answer:

The correct option is D.

But option B is correct if P(A) = P(B).

Step-by-step explanation:

P(A|B) is read as "The probability of A given B".

It is different from the options A, B, and C.

It is equal to option B only if the probability of A is equal to the probability of B. That is P(A|B) = P(B|A) if P(A) = P(B).

Solve for x: 6 over x equals 4 over 8

Talja [164]

Answer:

For the given expression, x = 12.

Step-by-step explanation:

Here, in the given expression:

6 over x equals 4 over 8.

Now, 6 over x = $\frac{6}{x}$

and 4 over 8 = $\frac{4}{8}$

So, here $\frac{6}{x} =\frac{4}{8}\\ \implies x = \frac{6 \times 8}{4} = 12$

⇒ x = 12

Hence, for the given expression, x = 12.

Which is the best estimate of x based on rounding the constants and coefficients in the equation to the nearest integer 6.15 (x

artcher [175]

Your answer would be x = 12.41

6.15 (x - 8.86) = 21.83
*6.15 * 6.15

6.15x - 54.49 = 21.83
+ 54.49 + 54.49

6.15x = 76.32
/6.15 /6.15

x = 12.41

Using a confidence interval, we have that:

a) The range is from 48.8% to 51.2%.

b) Between 125,000 and 131,000 adults are registered organ donors.

<h3>What is a confidence interval?</h3>

A confidence interval is given by the <u>estimate plus/minus the margin of error</u>.

For this problem, we have that:

The estimate is of 50%.

The margin of error is of 1.2%.

The bounds of the range are given as follows:

50% - 1.2% = 48.8%.

50% + 1.2% = 51.2%.

Hence the range is from 48.8% to 51.2%.

<h3>What are the total numbers?</h3>

We have to find <u>48.8% and 51.2% of 255,200,373</u>, hence:

0.488 x 255,200,373 = 124,537,782.

0.512 x 255,200,373 = 130,662,591.

Rounded to hundredth thousand, between 125,000 and 131,000 adults are registered organ donors.
