Rom4ik [11]

Answer:

Mrs. Wang is 38 years old and her daughter is 15 years old.

Step-by-step explanation:

Explanation:

Let

x

=

the daughter's age

Mrs. Wang is

23

years older, so her age is

x

+

23

In five years, the daughter will be

x

+

5

years old

In five years, Mrs. Wang will be

x

+

23

+

5

=

x

+

28

years old

And, in five years the sum of their ages will be 63, so...

x

+

5

x

+

28

=

63

Combine like terms

Th term of a seq uence is n(n-4) /n+3 Work out the sum of the 1st and 6th terms.
AlekseyPX

Answer:

7/12

Step-by-step explanation:

The nth term Tₙ = n(n-4) /n+3.

The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4

The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3

So,  the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3

= (-9 + 16)/12

= 7/12

AMERICAN AIRLINES HAS A POLICY OF BOOKING AS MANY AS 15 PEOPLE ON AN AIRPLANE THAT CAN SEAT ONLY 14. (PAST STUDIES HAVE REVEALED
Blizzard [7]

Using the binomial distribution, there is a 0.0874 = 8.74% probability that not enough seats will be available.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

For this problem, the values of the parameters are given by:

n = 15, p = 0.85.

The probability that not enough seats will be available is P(X = 15), as the only outcome in which not enough seats will be available is when all 15 people who bought the ticket show up, hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 15) = C_{15,15}.(0.85)^{15}.(0.15)^{0} = 0.0874

0.0874 = 8.74% probability that not enough seats will be available.
