Hi! So for this word problem, you would just decide 117 devided by 2. You would get 58.5. After that, you will have to round. If it is 5 or higher, you round up. So the FINAL answer would be 59. Hope this helped!
Answer:
Tommy spent $17
Step-by-step explanation:
Mary spent half of what tommy spent. 8.50 x 2= 17
therefore tommy spent $17
Answer:
It can be done using poisson distribution.
λ = 30 calls/hr = 1.5 calls/3min
Now P(X=x)=e−λ.λxx!
So P(X=0)=e−1.5
Step-by-step explanation:
How many 8 can we fit in 144?
Start with 8•10=80, can’t fit another 80 so
Continue with 8•5=40 we have now 80+40=120 and we need 144 so are left 24
Finish with 8•3=24
Now we can group them
Multiplication: 8•10+8•5+8•3=144
Distributive : 8•(10+5+3)=144
So 144/8=10+5+3=18
To get rid of the -3 from the modulus your going to bring it over the equal sign
|2x+1|=3
To get rid of the modulus you square both sides.
Postivite 3 solution is:
Negative 3 solution is
Therefore x is -2 and 1
