A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number
mixas84 [53]

A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.

The size of the sample space is: (8, 16, 20, 24)

If a code is chosen at random, the probability that it has a letter that immediately follows an odd number is: (1/8, 1/6, 1/3, 2/5, 2/3)

If a code is chosen at random, the probability that D is in the code but is not in the first position is: (1/8, 1/6, 1/3, 2/5, 2/3)

Solve for v. -9/8 = v - 1/2
Usimov [2.4K]

Answer:

-  \frac{5}{8}

Step-by-step explanation:

-  \frac{9}{8}  = v -  \frac{1}{2}  \\  \\  \frac{1}{2}  -  \frac{9}{8}  = v \\  \\ \frac{4}{8}  -  \frac{9}{8}  = v \\  \\  \frac{4 - 9}{8}  = v \\  \\ v =  -  \frac{5}{8}  \\

Find the volume of the object shown. Use 3.14 for pi. Round your answer to the nearest hundredth.
Karolina [17]
Cut it up
1 cylinder and a half sphere

V cylinder=hpir^2
Vsphere=(4/3)pir^3

find each

H=7
r=4
sub

Vcylinder=7pi4^2
V=7pi16
V=112pi

Vsphere (multiply by 1/2 later)
V=(4/3)pi4^3
V=(4/3)pi64
V=(256/3)pi
V=85.33333333333333pi
multply by 1/2 since 1/2 sphere
V=42.6666666666pi

add them


Vclliner+1/2sphere=112pi+42.66666666666pi=154.666666666666pi
pi=3.14 for problem
Vtotal=485.6533333333333333333
hundreth

V=485.65 in^3
