Mathematics
1 answer:
OLga [1]4 years ago
6 0

Step-by-step explanation:

1.5 mi = 2 and 1/4 min

In 43 minutes:

43 ÷ 2.15 = 20             2.15 = 2 and 1/4 min

Now you have to multiply 1.5 by 20

1.5 x 20 = 30

In 1 hour (60 minutes):

60 ÷ 2.15 = 27.9

Now you have to multiply 1.5 by 27.9

1.5 x 27.9 = 41.85

Hope this was helpful :)

Find the probability of at least three successes in six trials of a binomial experiment in which the probability of success is 5
Amanda [17]

Answer:

31.3%

Step-by-step explanation:

Start by doing the binomial expansion of (x+y)^6 where x represents success. This is  

(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)  

We are interested in the x^3y^3 term which represents exactly 3 successes. Since the probability of success and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is  

20/64 = .3125 which is 31.25% Rounding yo the nearest tenth gives us

What is 2/10 divided by 2/4
shtirl [24]

Given:

\dfrac{2}{10} divded by \dfrac{2}{4}.

To find:

The solution for the given division problem.

Solution:

We have, \dfrac{2}{10} divded by \dfrac{2}{4}. It can be written as

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}

\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}

Therefore, the solution for the given division problem is \dfrac{2}{5}.
