V (cube)=9³=729 cm³
V (cone)=1/3*π*R²*H= 1/3*π*3²*9=84.8 cm³
V (metal)= 729-84.8=644.2 cm³
Here we have to find the probability
. Now express the probability in terms of standard normal cumulative distribution function. That is
.
![P(-2.25](https://tex.z-dn.net/?f=%20P%28-2.25%3Cz%3C1.25%29%3D%5CPhi%281.25%29-%5CPhi%28-2.25%29%20)
Now you can look up the probability from the standard normal tables. Its value is
![P(-2.25](https://tex.z-dn.net/?f=%20P%28-2.25%3Cz%3C1.25%29%3D%5CPhi%281.25%29-%5CPhi%28-2.25%29%5C%5C%20P%28-2.25%3Cz%3C1.25%29%3D0.8821%20)
Answer:
(-4, 2).
Step-by-step explanation:
8x + 5y=-22
-3x - 5y = 2 Adding the 2 equations:
5x = -20
x = -4.
Substitute x = -4 in the first equation:
8(-4) + 5y = -22
5y = -22 + 32
5y = 10
y = 2.
Answer:
the answer will be 3.5 i think
Step-by-step explanation:
Answer:
for first car
c = 250 + 0.02*$115,075 = 2551.5
for second car
c= 250 + 0.02*$21,640 = 682.8
total commission= 2551.5 +682.8 = 3234.3
