The ratio of fishing boats to sailboats in a bay is 8:3. There are a total of 24 sailboats in the bay. How many fishing boats ar
lianna [129]

Answer:

The number of fishing boats in the bay = 64.

Step-by-step explanation:

The total number of sailboats  = 24

Let us assume the number if fishing boats in the bay = m

⇒ Ratio of fishing boats to sailboats in a bay =  m  :  24.

Now, the ratio of fishing boats to sailboats in a bay is 8  :  3.

So, by the RATIO OF PROPORTION:

\frac{m}{24}  = \frac{8}{3}  \implies m = \frac{8}{3} \times 24 = 64

⇒  m = 64

Hence the number of fishing boats in the bay = 64.

A train travels 250 miles at a constant speed (x), in miles per hour.Enter an equation that can be used to find the speed of the
Nastasia [14]
The first thing we must do for this case is to take into account the following variable:
 x = speed in miles per hour
 Then, by definition we have to:
 d = v * t
 Where,
 d: distance
 v: speed
 t: time
 Substituting values:
 250 = x * 5
 Answer:
 
An equation that can be used to find the speed of the train is:
 
250 = x * 5

For a recent report on sleep deprivation, the Centers for Disease Control and Prevention interviewed 11600 residents of Californ
Pani-rosa [81]

Answer:

H0: p1-p2=0

Ha: p1-p2≠0

This hypotheses can be written as

H0: p1=p2

Ha: p1 ≠p2  

Step-by-step explanation:

Here the claim is if these data provide strong evidence the rate of sleep deprivation is different for the two states which will be formulated as alternate hypothesis .

Ha: p1-p2≠0  

The null hypothesis is

H0: p1-p2=0  i.e these data  do not provide strong evidence the rate of sleep deprivation is different for the two states.

where p1  =   as population 1 of California

p2= as population 2 of Oregon

This hypotheses can be written as

H0: p1=p2

Ha: p1 ≠p2  

which will also give the same results as above and a two tailed test will be performed for both hypotheses.
