Answer:
There are 15,112 gallons of water will remaining in the pool ⇒ answer D
Step-by-step explanation:
* Lets explain how to solve the problem
- The rate is the ratio between two related quantities in different units
- The pool is leaking slowly at rate 9 gallons per second that means the
quantity of the water in the pool decreased 9 gallons each day
- The find the remaining gallons in the pool after 111 days, find the
amount of water has leaked from the pool in these days
∵ The rate of leaking is 9 gallons per day
∵ Mike does not replace the water that has leaked from the pool
- The amount of water leaked in some days = the rate of leaking
× the number of days
∵ The number of days is 111 days
∵ The amount of water lacked = 9 × 111 = 999 gallons
∵ The amount of water remaining in the pool after some days =
the total amount in the pool - the amount of leaked in that days
∵ The pool holds 16,111 gallons of water
∴ The amount of water remaining = 16111 - 999 = 15112 gallons
* There are 15,112 gallons of water will remaining in the pool
What can she infer about the wingspans of the two types of birds?
Type 1: {18, 24, 20, 22, 26}
Type 2: {24, 21, 19, 26, 30}
A.
Type 1 and Type 2 birds have similar wingspan distributions.
B.
Type 1 and Type 2 birds have somewhat similar wingspan distributions.
C.
Type 1 birds and Type 2 birds do not have similar wingspan distributions.
D.
Type 1 birds and Type 2 birds have identical wingspan distributions.
Answer:
Step-by-step explanation:
The given data set for type 1 of birds is:
Type 1: {18, 24, 20, 22, 26}
Type 2: {24, 21, 19, 26, 30}
Mean of the type 1 data is:
Data
18 16
24 4
20 4
22 0
26 16
Now, mean average of squares is:
Standard deviation=
Now, the difference of mean and its standard deviation of type 1 data set is:
=22-2.828
Difference =19.172
The given data set for type 2 of birds is:
Type 2: {24, 21, 19, 26, 30}
Mean of the type 2 data is:
Data
24 0
21 9
19 25
26 4
30 36
Now, mean average of squares is:
Standard deviation=
Now, the difference of mean and its standard deviation of type 2 data set is:
=24-3.84
Difference=20.16
Since, the difference of mean and standard deviation of both type 1 and type 2 data set is different, therefore, Type 1 birds and Type 2 birds do not have similar wingspan distributions.
Hence, option C is correct.
Answer:
Type 1 and Type 2 birds have similar wingspan distributions.
