HELP PLEASE I WILL GIVE BEST ANSWERAngela is studying two types of birds. She measures the wingspan, in inches, of five Type 1 birds and five Type 2 birds.
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.

The rate of 4 centimeters per second is equal to 144 meters per hour.
What is unit conversion?
A conversion factor is a ratio that expresses how many of one unit are equal to another unit. To convert a smaller unit to a larger unit (eg to ), divide it by the number of smaller units which are needed to make larger unit. To convert from a larger unit to a smaller one, multiply. To convert from a smaller unit to a larger one, divide.
For the given situation,
4 centimeters per second is equal to how many meters per hour.
1 centimeter =
⇒
⇒
1 second =
Thus 4 centimeters per second = ÷
⇒ ×
⇒
Hence we can conclude that the rate of 4 centimeters per second is equal to 144 meters per hour.

First step, work out how many seconds in an hour
(seconds) 60 x (minutes) 60
60 x 60 = 3600 seconds in an hour
1 seconds = 4 cm
x3600 to get the distance in cm/h
3600 seconds (1 hour) = 14,400cm
Divide by 100 for m/h
14400/100 = 144 meters per hour

Hi there! :D So you're wondering what's 6 3/4+3 5/6, right? Well first of all, we need to find a common denominator. In this case, we can use 12. (In case you don't know how to make common fractions, here's the steps:
1. Select your two numbers, 3/4 and 5/6. We multiply 4 x 6 = 24. That's the common denominator. But, we can reduce that to 12 by dividing by 2.
2. Multiply. 3/4 = 9/12. You must multiply by the same number. (3 x 3 = 9 and 4 x 3 = 12). Do that for 5/6 and you'll get 10/12.
Now we do 6 9/12 + 3 10/12. Add. 6 + 3 = 9 and 9/12 + 10/12 = 19/12 which equals 1 7/12 + 9 = 10 7/12.
10 7/12 is the answer you're looking for! Hope it helped! :D
