8 0

Answer:

18  jumps would be  expected in a 2 hour period.        

Step-by-step explanation:

Given : A dolphin jumps 54 times in a 6 hour  period.

To find : At this rate, how many jumps would be  expected in a 2 hour period?​

Solution :

Applying unitary method,

In 6 hour period Dolphin jumps 54 times.

In 1 hour period Dolphin jumps \frac{54}{6} times.

In 1 hour period Dolphin jumps 9 times.

In 2 hour period Dolphin jumps 2\times 9 times.

In 2 hour period Dolphin jumps 18 times.

Therefore, 18  jumps would be  expected in a 2 hour period.

The height of a free falling object at time t can be found using the function, h(t) = - 12t2 + 36t. Where h(t) is the height in
never [62]
For this case we have the following equation:
 h (t) = - 12t2 + 36t
 When the object hits the ground we have:
 - 12t2 + 36t = 0
 We look for the roots of the polynomial:
 t1 = 0
 t2 = 3
 Therefore, the time it takes the object to hit the ground is:
 t = 3 s
 Answer:
 
the time when the object hits the ground is:
 
t = 3 s

Determine the point estimate of the population proportion, the margin of error
ahrayia [7]

Answer:

\hat p=0.645\\\\ME=0.233\\\\x=645 \ individuals

Step-by-step explanation:

-Given the boundaries as 0.412 and 0.878

-\hat p is the point estimate for the population proportion and is calculated as follows:

\hat p=\frac{Upper \ Bound+Lower \ Bound}{2}\\\\=\frac{0.878+0.412}{2}\\\\=0.645\\\\

#The margin of error, ME can be calculated for the confidence intervals using the formula:

ME=\frac{Upper \ Bound-Lower \ Bound}{2}\\\\=\frac{0.878-0.412}{2}\\\\=0.233

#The number of individuals in the sample is the product of the point estimate and population size:

\hat p=\frac{x}{n}\\\\x=\hat pn\\\\=0.645\times 1000\\\\=645

Hence, there are 645 individuals in the sample.

What is greater, 85/100 or 21/25?
Elodia [21]


85/100 is greater

85/100=.85 or 85%

21/25=.84 or 84%

.85 is greater than .84 so 85/100 > 21/25
