Solve for the value of x

Mathematics
1 answer:
viva [34]2 years ago
4 0

Answer:

x=9

Step-by-step explanation:

To solve for x, you can set up a proportion between the 2 triangles we see.

The small triangle can be written as \frac{16}{20}, and the large triangle can be written as \frac{16+12}{20+2x-3} = \frac{28}{2x+17}.

Set both proportions equal to each other.

\frac{16}{20}=\frac{28}{2x+17}

Cross multiply and solve for x.

16(2x+17)=(28)(20)

32x+272=560

32x=288

x=9

Suppose that the duration of a particular type of criminal trial is known to be normally distributed with a mean of 22 days and
Alika [10]

Answer:

25.5 days

Step-by-step explanation:

Mean number of days (μ) = 22 days

Standard deviation (σ) = 6 days

Z-score for the 72nd percentile (according to tabulated values) = 0.583

The z-score for any number of days, X, is determined by:

z=\frac{X-\mu}{\sigma}

The value of X that is greater than 72% of the trial times is:

0.583=\frac{X-22}{6}\\ X=25.5\ days

Therefore, 72% of all of these types of trials are completed within 25.5 days.
