Readme [11.4K]

Answer:

v = 80 mph

Step-by-step explanation:

Given that,

The distance from Wakefield to London is 180 miles.

The train travels this distance in 2 hours 15 minutes.

We need to find the average speed of the train. The average speed of the train is equal to the total distance covered divided by the time taken.

$v=\dfrac{d}{t}\\\\v=\dfrac{180\ miles}{(2+\dfrac{15}{60})\ h}\\\\v=80\ mph$

So, the required average speed of the train is 80 mph.

What are the real and complex solutions of the polynomial equation? X4-41x2=-400

stich3 [128]

For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
=> x^4 - 41x^2 + 400 = 0 
=> x^2 = (1/2) [41 ±√(1681 - 100)] 
=> x^2 = (1/2) (41 ± 9) 
=> x^2 = 16 or 25

So, therefore, the answers for your problem are
=> x = ± 4 or ± 5.

I hope my answer helped you.

There is a 70% chance that your car will get stuck in the snow during the next big snow fall. Given that you are already stuck i

nikdorinn [45]

Answer:

63%

Step-by-step explanation:

This is a problem of conditional probability.

The two events that are given are:

Car stuck in the snow - Let it be event S. P(S) = 70% = 0.70
Require a tow truck - Let it be event T.

We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)

We are also given the conditional probability, which is P(T | S) = 90% = 0.90

Using the given formula for our case we can modify the formula as:

$P(T|S)=\frac{P(S \cap T)}{P(S)}$

$0.90=\frac{P(S \cap T)}{0.70}\\\\ P(S \cap T)=0.90 \times 0.70\\\\ P(S \cap T)=0.63$

Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out
