The answer can be either y = 1.5 or y = 1 1/2
Answer:
95%
Step-by-step explanation:
The z-scores associated with the limits are ...
z = (x -μ)/σ
z = ({80, 108} -94)/7 = {-14, 14}/7 = {-2, 2}
That is, we're interested in flight times that lie within 2 standard deviations of the mean. The empirical rule tells us that 95% of the distribution lies within 2 standard deviations of the mean.
Answer:
The expression a^b
means that we multiplicate the number a by itself b times.
So x^2 means that we multiplicate the number x by itself 2 times:
x^2 = x*x
and 2^x means that we multiplicate the number 2 by itself x times
2^x = 2*2*2*....*2 (if you count them, you should see x times the number 2)
for example, if x = 4, we will have
2^4 = 2*2*2*2
The Volume for Rectangular prism A is 172 inches², Volume = 112 inches³
Surface Area to Volume Ratio = 43/28
<h3>Mensuration of Solids</h3>
Given Data
Rectangular prism A
Length = 2 inches
Width = 7 inches
Height = 8 inches
Surface Area
A=2(wl+hl+hw)
A=2(7*2+8*2+8*7)
A=2(14+16+56)
A= 172 inches²
Volume
Volume = L*W*H
Volume = 2*7*8
Volume = 112 inches³
Surface Area to Volume Ratio
= 172/112
= 43/28
