What is the value of x?<br> 12 units<br> 15 units<br> 20 units<br> 25 units

Firlakuza [10]

Answer:

The answer is 12 units.

Step-by-step explanation:

Looking at the figure we see that

$(1).9^2+x^2=SR^2$

$(2).16^2+x^2=RQ^2$ and

$(3).SR^2+RQ^2=(9+16)^2$

Now from equations (1) and (2) we have values for $SR^2$ and $RQ^2,$ so we put those into the equation (3) and get:

$9^2+x^2+16^2+x^2=(9+16)^2$

$\rightarrow 337+2x^2=625$

$\boxed{\therefore x= 12.}$

Therefore the answer is 12 units.

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m. Based on past experience the company has determin

Gala2k [10]

Answer:

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m.

We can consider 8 am = 0, and 8:30 am = 30, so $a = 0, b = 30$

Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Between 15 and 25, so:

$P(15 \leq X \leq 25) = \frac{25 - 15}{30 - 0} = 0.3333$

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.
