Mathematics
1 answer:
Paul [167]2 years ago
7 0

Answer:

\frac{5}{6} = x

Step-by-step explanation:

\frac{3}{7}x = \frac{5}{14} \\ \\ \frac{5}{14} \div \frac{3}{7} = \frac{5}{14} \times \frac{7}{3} = \frac{35}{42} = \frac{5}{6}

Use multiplication [inverse of division] to figure this out.

* 2⅓ = 7⁄3

I am joyous to assist you anytime.

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p
aev [14]

Answer:

P(X < 3) = 0.7443

Step-by-step explanation:

We are given that the random variable X has a binomial distribution with the given probability of obtaining a success. Also, given n = 6, p = 0.3.

The above situation can be represented through Binomial distribution;

P(X=r) = \binom{n}{r}p^{r} (1-p)^{n-r} ; x = 0,1,2,3,.....

where, n = number of trials (samples) taken = 6

            r = number of success = less than 3

           p = probability of success which in our question is 0.3.

LET X = a random variable

So, it means X ~ Binom(n=6, p=0.3)

Now, Probability that X is less than 3 = P(X < 3)

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

             = \binom{6}{0}0.3^{0} (1-0.3)^{6-0}+ \binom{6}{1}0.3^{1} (1-0.3)^{6-1}+ \binom{6}{2}0.3^{2} (1-0.3)^{6-2}

             = 1 \times 1 \times 0.7^{6}  +6 \times 0.3^{1}  \times 0.7^{5}  +15 \times 0.3^{2}  \times 0.7^{4}

             = 0.11765 + 0.30253 + 0.32414 = 0.7443

Therefore, P(X < 3) = 0.7443.

Erica can run 1/6 of a kilometer her school is 3/4 of a kilometer away from her home at this this speed how long would it take e
shepuryov [24]

Answer:

4 minutes 30 seconds

Step-by-step explanation:

Given:

Erica can run 1/6 of a kilometer in one minute.

Her school is 3/4 of a kilometer away from her home.

Question asked:

How long would it take Erica to run home from school = ?

Solution:

As here distance is  given and also speed is given, we will find time taken to run from home to school by using,

Speed=\frac{Distance}{Time} \\ Time =\frac{Distance}{Speed} \\

         =\frac{3}{4} \div\frac{1}{6} \\\\ =\frac{3}{4} \times\frac{6}{1} \\\\ =\frac{18}{4} \\ \\ =\frac{9}{2} \\ =4.5 \ minutes

Therefore, it takes 4 minutes 30 seconds Erica to run home from school.
