Michael is 121212 years older than Brandon. Seventeen years ago, Michael was 444 times as old as Brandon. How old is Michael now?

Answers

Let Brandon's age be = b years

Let Michael's age be = m years

As Michael is 12 years older than Brandon, Michael's age, so

$m=b+12$

Seventeen years ago, Michael was 4 times as old as Brandon, so

$m-17=4(b-17)$

$m-17=4b-68$

$m=4b-51$

$m-4b=-51$

Substitute m=b+12

$b+12-4b=-51$

$-3b=-63$

$b=21$

Hence, Brandon's age is 21 years

As m=b+12

$m=21+12$

$m=33$

Hence, Michael's age is 33 years.

If 3 waves happen in 6 seconds how many happen in 1 second? How do I solve this and what's the answer?

Answers

you would do 3 divided by 6 and that would give you th answer and the answer is 0.5 so that would mean half a wave happens every second

2x+y=4
Y=2/3x-4

Answers

so you subsitute y=2/3x-4 for y in 2x+y=4 so
2x+(2/3x-4)=4
2x+2/3x-4=4
add like terms
2 and 2/3x-4=4
add 4 to both sidees
2 and 2/3x=8
2 and 2/3=6/3+2/3=8/3
8/3x=8
multiply both sides by 3/8 (makes 8/3=24/24=1/1=1)
x=(3*8)/8
simplify
x=3
subtitute x=3 into y=2/3x-4
y=2/3(3)-4
y=(6/3)-4
y=2-4
y=-2

HELP ASAP PLEASE???!!!

Answers

You need to start by multiply all terms by (x-2)(x+1) and cancel

x(x+1)(x-1)(x-2)=-1(x-2)(x+1)

2x²-2x+2=-x²+x+2

Now you need to subtract -x²+x+2

2x²-2x+2-(-x²+x+2)=-x²+x+2-(-x²+x+2)

3x²-3x=0

Now factorize

3x(x-1)=0

3x=0 or x-1=0

x= 0 or x=1

A basketball player is shooting free throws blindfolded. He shoots in groups of 4 shots. Assume that it is equally likely that he will hit or miss a shot. Design and do a simulation to determine the probability that he will hit at least 75% of his shots within the groups. (Hint: Use coins.)

Answers

Let H represent hit and M represent miss, Then sample space

MMMM, MMMH, MMHM, MHMM, HMMM, MMHH, MHMH, HMMH, MHHM, HMHM, HHMM, MHHH, HMHH, HHMH, HHHM, HHHH

He hit at least 75% in 5 occasions.

Therefore, P(hit at least 75%) = 5/16

Answer:

Use 4 coins. Let heads = hit and tails = miss. Toss each coin and record the results in a table. Coin 1Coin 2Coin3Coin 4Set 1HHHHSet 2HTHHSet 3HHTHSet 4THTTSet 5

Repeat the coin tosses until you have recorded 50 sets of 4 tosses each. b. Count the successful outcomes—those with three or four heads. Coin 1Coin 2Coin3Coin 4SuccessSet 1HHHHxSet 2HTHHxSet 3HHTHxSet 4THTTSet 5
