Answer: 0.125 mg per half minute
Step-by-step explanation:
15mg per hour can be written as 15mg/h
To find out how many mg of medication are delivered per half minute you can convert from hour to minutes
There are 60 minutes in 1 hour, so you can use the conversion factor (1h/60 min) and multiply the expression by it
15 mg/h (1h/60min) = 0.25 mg/min
But the question is per half minute so you have to multiply and divide the previous expression by 0.5 (To obtain 0.5 min in the denominator, which is half minute)
Then,
(0.25 mg/min ) (0.5/0.5) = 0.125 mg/ 0.5 min (0.125 mg per half minute)
Answer:
There are 24 cats at the shelter on Wednesday.
Step-by-step explanation:
Since we have given that
Cost of an animal shelter per day to care for each cat =$1.00
Cost of an animal shelter per day to care for each dog = $4.50
Let number of cats be c
Let number of dogs be d
According to question,
We will use "Substitution Method ",
Put in the second equation :
so, Number of dogs = 25
and
Hence, Number of cats is 24.

Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × ×
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × ×
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × + 15C5 ×
P = ( 15C8 + 15C5 )
P = ( ( ) + ( ) )
P = ( 6435 + 3003 )
P = ( 9438)
P = ( 4719)
P =
P = 0.29
