Answer:

At the same rate Rose will run 3 miles in 42 minutes.

Step-by-step explanation:

Hint- This problem ca be solved using Unitary method.

This Here given that, Rose can run 4 miles in 56 minutes.

i.e Rose in 56 minutes can run 4 miles.

So Rose in 1 minutes can run $\dfrac{4}{56}$ miles.

So Rose in 42 minutes can run $\dfrac{4}{56}\times 42=3$ miles.

Therefore, if Rose can run 4 miles in 56 minutes, she will run 3 miles in 42 minutes.

$\frac{56}{42} = \frac{4}{x}$ then you figure out what you divide 56 by to get 4. which is 14. then you divide 42 by the same number 14.

A 1L bag of Normal Saline must infuse over 6 hours using tubing calibrated to deliver 20gtts/mL. How many drops per minute shoul

sammy [17]

Answer:

total drop per minute is 56

Step-by-step explanation:

Give data:

total capacity of bag 1 L = 1000 ml

Duration of infuse 6 hr

quantity at the time delivered is 20 gtts/ml

Drop per minute can be determined by using following relation

Drop per minute $= \frac{1000 ml\times 20 gtts/ml}{6\times 60 min} = 55.55 gtt$

therefore total drop per minute is $55.55 \approx 56$

Answer:

(x-8) (x+3)

Step-by-step explanation:

x^2−5x−24

We need two numbers that multiply to negative 24 and add to negative 5

An airline knows that 5 percent of the people making reservations on a certain flight will not show up. Consequently, their poli

kenny6666 [7]

Answer:

the probability that there will be a seat available for every passenger who shows up is 0.74

Step-by-step explanation:

if the probability of choosing a passenger that will not show up is 5% , then the probability of choosing a passenger that will show up is 95%.

Denoting event X= x passengers will show up from the total of 52 that purchased the ticket

Then P(X) follows a binomial probability distribution, since each passenger is independent from others. Thus

P(X) = n!/((n-x)!*x!)*p^x*(1-p)^(n-x)

where

n= total number of passengers hat purchased the ticket= 52

p= probability of choosing a passenger that will show up

x = number of passengers that will show up

therefore the probability that the number does not exceed the limit of 50 passengers is:

P(X≤50)= ∑P(X=i) from i=0 to i=50 =F(50)

where F(x) is the cumulative binomial probability distribution, then from tables:

P(X≤50)= F(50) = 0.74

therefore the probability that there will be a seat available for every passenger who shows up is 0.74
