Answer:

Correct choice is A. P(A|B)=\frac{40}{49}.

Step-by-step explanation:

Given that P(A\cap B)=\frac{5}{7}, P(B)=\frac{7}{8}.

Now using those values , we need to find the value of P(A|B).

So apply the formula of conditional probability:

P(A\cap B)=P(B) \times P(A|B)

Plug the given values into above formula,  we get:

\frac{5}{7}=\frac{7}{8} \times P(A|B)

\frac{7}{8} \times P(A|B)=\frac{5}{7}

P(A|B)=\frac{\frac{5}{7}}{\frac{7}{8}}

P(A|B)=\frac{5}{7}\cdot\frac{8}{7}

P(A|B)=\frac{40}{49}

Hence correct choice is A. P(A|B)=\frac{40}{49}.

Answer: Option A

P(A|B) = \frac{40}{49}

Step-by-step explanation:

In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

P(A|B) = \frac{P(A\ and\ B)}{P(B)}

Then if P(A\ and\ B) = \frac{5}{7} and P(B) = \frac{7}{8} then:

P(A|B) = \frac{\frac{5}{7}}{\frac{7}{8}}\\\\P(A|B) = \frac{40}{49}

One type of insect is 0.0052 meter long. What is this length in scientific notation?
____ [38]
Ok so...

You want to move the decimal point to the right until the number is greater than 1 but less than 10.

The number will end up being 5.2

You moved the decimal point 3 times to the right.
So it will be 5.2 x 10^-3. It is negative because you moved it to the right. The exponent would be positive if you moved it to the left

What is the meaning of the t-intercept of the altitude graph? The y-intercept?
Gnom [1K]

Answer: Hello mate!

We know that you have a graph of y vs t, and we know that this is an "altitude" graph.

Then we can assume that the y represents the altitude, and t represents the time, and this graph shows the altitude of something as a function of the time.

the t-intercept means that the graph passes through the y-axis, this means that, in this point, y is equal to zero:

Then, at the t-intercept, we have y = 0, which means that at this time (where is the intersection) the altitude is equal to zero.

The y-intercept means that the graph passes through the y-axis, where t = 0

this is the initial value of the altitude, where t = 0 usually denotes the time where we start to measure.
