14 V = bdt. Solve the formula for de
snow_tiger [21]

Answer:

d=\dfrac{V}{bt}

Step-by-step explanation:

It is given that,

V = bdt i.e. V is equal to the product of b, d and t

We need to find the formula for d.

Dividing both sides of the given expression by bt

So,

\dfrac{V}{bt}=\dfrac{bdt}{bt}\\\\d=\dfrac{V}{bt},\ \text{bt in both denominator and numerator cancel out}

Hence, d=\dfrac{V}{bt} is the value of d.

How do you do these 4 questions and the reasons?
Afina-wow [57]

Step-by-step explanation:

"There are several flights that have very long delays."

True.  On the boxplot, we can see several outliers greater than the maximum.

"More than 25% of flights are either exactly on time or arrive early."

False.  According to the 5 number summary, 25% of the flights are between -55 and 13.  So less than 25% of the flights are on time or early.

"About 50% of flights are delayed between 13 and 35 minutes."

False.  According to the 5 number summary, 25% of the flight times are less than 13 minutes, and 50% of the flights are less than 35 minutes.  So 25% of the flights are delayed between 13 and 35 minutes, not 50%.

"About 25% of flights are delayed by more than 78 minutes."

True.  According to the 5 number summary, 75% of the flights are delayed less than 78 minutes.  Which means 25% of the flights are delayed more than 78 minutes.

(Ross, 4.78) A jar contains 4 white and 4 black marbles. We randomly choose 4 marbles. If 2 of them are white and 2 are black, w
KATRIN_1 [288]

Answer:

Step-by-step explanation:

Given

Jar contains 4 white and 4 black marbles

We randomly select 4 marbles out of which 2 are white and 2 are black

Probability that 2 white and 2 black marbles are selected is

P=\frac{^4C_2\times ^4C_2}{^8C_4}

P=\frac{18}{35}

The process is continue for n trails until we choose the correct order

i.e. we have to fail in n-1 trails

For exact n selection Probability is given by

Req.\ Probability=Probability\ of\ failure\ in\ (n-1)\ trials\times Probability\ of\ getting\ exact\ order

=\left ( 1-\frac{18}{35}\right )^{n-1}\times \frac{18}{35}
