Answer:
a)8cm
b)30inches
Step-by-step explanation:
Answer: 3 x 7
Explanation:
So the question is asking you to multiply two prime numbers in order to get 21.
Since 3 and 7 are both prime numbers, you can express 21 as 3 x 7
Hope this helps! :)
Here is a list of prime numbers if it helps you. (prime numbers are in blue):
Answer:
4
Step-by-step explanation:
it is 4 because 4-2=2
2*2=4
Given the data below <span>representing the body mass index (bmi) values for 20 females.
17.7 33.5 26.9 22.7 22.2 29.9 23.6 18.3 27.7 23.4 19.2 25.9 22.9 37.7 31.6 28.1 44.9 31.6 25.2 23.9
From the data above, we construct a frequency distribution beginning with a lower class limit of
15.0 and use a class width of 6.0 as follows:
Class iinterval: 15.0 - 21.0 21.0 - 27.0 27.0 - 33.0 33.0 - 39.0 39.0 - 45.0
Frequency: 3 9 5 2 1
From the frequency table, it can be seen that the frequencies started low, increased to a point and then decrease. It can also be seen that the highest frequency of the data is not at the center of the distribution, so the distribution is not symetric.
Therefore, the frequency
distribution does not appear to be roughly a normal distribution, because, "although the frequency start low, increase to some maximum, then decrease, the distribution is not symmetric."</span>
To round to 3 sign. fig. you have to look at your fourth figure, is it between 0-4? If yes, then it´s should be rounded down. Is it between 5-9? If no, then it´s should be rounded up.
Now, in this case the fourth figure is 4, meaning it should be rounded down..
198 is therefore your answer:D
Have a nice day
