Using the uniform distribution, it is found that there is a 0.3 = 30% probability that Samantha has to wait less than 4.5 minutes to catch the bus.

<h3>What is the uniform probability distribution?</h3>

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value of at lower than x is:

P(X < x) = \frac{x - a}{b - a}

In this problem, the time is uniformly distributed between 0 and 15 minutes, hence the bounds are a = 0 and b = 15.

The probability that Samantha has to wait less than 4.5 minutes to catch the bus is given by:

P(X < 4.5) = \frac{4.5 - 0}{15 - 0} = 0.3

1. Kane earns an annual salary of $42,500.
Katarina [22]

Answer:

$1753.13

Step-by-step explanation:

Kane's Annual Salary  = $42,500

Gross Pay = $42,500

Net Pay = Gross Pay - 1% of Gross Pay

=42500 - (0.01 X 42500)

=$42,075

Since he is paid twice a month with paychecks being  of equal amounts.

Number of Payments in a Year =12 X 2= 24

Therefore, Kane's Take Home pay after Medicare taxes

= \$42075 \div 24\\=\$1753.13$ (to the nearest cent)

If sin150=1/2 then find sin75
Darya [45]

Sin75° = Sin(30° + 45°)

= Sin30°.Cos45° + Sin45°.Cos30°

= 1/2 . √2/2 + √2/2.√3/2

= √2/2 ( 1/2 + √3/2 )

= √2/2 ((1+√3 ) /2 )

= (√2 + √6 )/ 4

If a b and C are integers greater than 1 and if ab=21 and bc=39 which of the following must be true?
Zina [86]
A * b = 21 and b * c = 39. then b is the common factor of the two numbers.

We need to factor these two numbers to know their equivalent values.

21 factors are 1, 3, 7, 21
39 factors are 1, 3, 13, 39

if b = 3, then a = 7 and c = 13.  

To check:
a * b = 21 where 7 * 3 = 21              and          b * c = 39 where  3 * 13 = 39
 
We can then conclude the following:

3 is lesser than 7 which is lesser than 13. where b < a < c

OR 13 is greater than 7 which is greater than 3. where c > a > b

not sure if these answers are included in your choices but i hope this helps.
