Answer:

$10.8\ yd$

Step-by-step explanation:

<u><em>The complete question is</em></u>

Jessica has 84.5 yards of fabric to make curtains. She makes 6 identical curtains and has 19.7 of fabric remaining. How many yards of fabric does Jessica use per curtain?

Let

x-------> amount of yards of fabric that Jessica used per curtain

we know that

The length of 6 identical curtains plus the length of the fabric remaining, must be equal to the total yards of fabric'

The linear equation that represent this situation is

Solve for x

$6x=84.5-19.7\\6x=64.8\\x=10.8\ yd$

The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.

From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x

We can further deduce that
tan(Θ) = $\frac{y}{x}$
sec(Θ) = $\frac{1}{cos(Θ)}$ = $\frac{1}{x}$
cosec(Θ) = $\frac{1}{sin(Θ)}$ = $\frac{1}{y}$
cot(Θ) = $\frac{cos(Θ)}{sin(Θ)}$ = $\frac{x}{y}$

Answer:

For the 99th percentile, we have X = 206 seconds.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 138.5, \sigma = 29$
