Answer:
$1256.85
Step-by-step explanation:
1140 (1.05) = $1197 cost
$1197* 1.05 = 5% profit
Answer:
C- Divide both sides by 3.
Step-by-step explanation:
In order to isolate the variable, we will have to remove all non-1 coefficients from the variable. Since 3b can be written as 3(b), b is being multiplied by 3. So the only way to isolate the variable is to do inverse operations, which would be to divide both sides of the inequality by 3.
Hope this helped!
Answer:
Step-by-step explanation:
![Z=\frac{x-mu}{\sigma }](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx-mu%7D%7B%5Csigma%20%7D)
X - Heights of women aged 20 to 29: X is N(64, 2.7)
Y - Heights of men aged 20 to 29: X is N(69.3, 2.8)
a) X=6'=72"
Z=![\frac{72-64}{2.7} =2.963](https://tex.z-dn.net/?f=%5Cfrac%7B72-64%7D%7B2.7%7D%20%3D2.963)
b) Y = 72"
z=![\frac{72-69.3}{2.8} =0.965](https://tex.z-dn.net/?f=%5Cfrac%7B72-69.3%7D%7B2.8%7D%20%3D0.965)
c) 72' women can be taken as very tall but men moderately taller than average
d) Y<5'5" =65"
Z<![\frac{65-69.3}{2.8} =-1.536](https://tex.z-dn.net/?f=%5Cfrac%7B65-69.3%7D%7B2.8%7D%20%3D-1.536)
e) X>73"
Z>![\frac{73-64}{2.7} =3.33](https://tex.z-dn.net/?f=%5Cfrac%7B73-64%7D%7B2.7%7D%20%3D3.33)
Almost 0% can be taken
f) IQR =Q3-Q1
Z scores =
