Answer:
If we compare this value with the 47.3 proposed we have the following error
The computed mean is close to the actual mean because the difference between the means is less than 5%.
Step-by-step explanation:
Assuming the following dataset:
Speed 42-45 46-49 50-53 54-57 58-61
Freq. 21 15 6 4 2
And we are interested in find the mean, since we have grouped data the formula for the mean is given by:
And is useful construct a table like this one:
Speed Freq Midpoint Freq*Midpoint
42-45 21 43.5 913.5
46-49 15 47.5 712.5
50-53 6 51.5 309
54-57 4 55.5 222
58-61 2 59.5 119
Total 48 2276
And the mean is given by:
If we compare this value with the 47.3 proposed we have the following error
The computed mean is close to the actual mean because the difference between the means is less than 5%.
Answer:
The principal borrow for loan is $1,500 .
Step-by-step explanation:
Given as :
The interest paid on simple interest = s.i = $240
The rate of simple interest applied = r = 4%
The time period for loan = t = 4 years
Let The principal borrow = $p
Now,<u> from Simple Interest method</u>
Simple Interest =
Or. s.i =
Or, $240 =
Or, $240 × 100 = 16 × p
Or, $24000 = 16 × p
∴ p =
i.e p = $1,500
So, The principal borrow for loan = p = $1,500
Hence, The principal borrow for loan is $1,500 . Answer
Answer:
Your answer is 31.4 units squared
Step-by-step explanation:
By doing 2πr, you'll get your answer.
2*3.14*5 = 2*15.7 = 31.4
Answer: ( -7 , -3 )
Step by step:
The point: ( X , Y )
Left 2 units = change X by -2
So, -5 subtract by 2 equals -7
Down 3 units = change Y by -3
So, 0 subtract by 3 equals -3
Now, X = -7 and Y = -3, so the answer is ( -7 , -3 )
