Answer:

Yes and Yes

Step-by-step explanation:

Simply put, a z-score (also called a standard score) gives you an idea of how far from the mean a data point is. But more technically it's a measure of how many standard deviations below or above the population mean a raw score is. A z-score can be placed on a normal distribution curve.

In a circle with a radius of 27  2/5 in., an arc is intercepted by a central angle of 7π/4 radians. What is the arc length? Use
nexus9112 [7]
\bf \textit{arc's length}\\\\
s=r\theta \quad 
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad radians\\
------\\
r=27\frac{2}{5}\\
\theta =\frac{7\pi }{4}
\end{cases}\implies s=27\frac{2}{5}\cdot \cfrac{7\pi }{4}\implies s=\cfrac{27\cdot 5+2}{5}\cdot \cfrac{7\pi }{4}
\\\\\\
s=\cfrac{137}{5}\cdot \cfrac{7\pi }{4}\implies s=\cfrac{959\pi }{20}

The length, L, of a rectangle is 4 times its width, W. The perimeter of the rectangle is greater than 60
polet [3.4K]

Answer:

w> 6

Step-by-step explanation:

Let w= the width

Let 4w = length

So then your equation becomes

2(w) + 2(4w) >60

Distribute

2w+8w > 60

Combine like terms

10w > 60

Divide by 10

w > 6
