Answer:
Step-by-step explanation:
Find the midpoint of each frequency range, multiply that number by the frequency, sum up and divide by the total frequency.
This will give the mean number.
<u>The mean is:</u>
- [17*( 3 + 3.5)/2 + 21*(3.5 + k)/2 + 33*(k + 4)/2 + 54*(4 + 4.5)/2 + 15*(4.5 + 6)/2]/140 = 4.09
- 55.25 + 10.5k + 36.75 + 16.5k + 66 + 229.5 + 78.75 = 140*4.09
- 17k + 466.25 = 572.6
- 17k = 572.6 - 466.25
- 17k = 106.35
- k = 106.35/17
- k = 6.26
Note, I expected the value of k between 3.5 and 4. This is a bit of illogical outcome.
What is 8% of 24.52= 1.9616
just round up
Answer:
Step-by-step explanation: L= length w= width p= perimeter
L=3W p=55CM
P. of rectangle= 2(l+w)=55cm
L+w= 55/2= 27.5 cm
3w+w=27.5cm
4w=27.5cm
w=27.5/4=6.875cm w=6.875cm L= 3w=6.875*3=20.625cm
The answer is E I did a test like this before and they try to trick you
Answer:
The ferris wheel has a maximum capacity of 64, the domain is [0,64]
Step-by-step explanation:
The ferris wheel has a maximum capacity of 64, the domain is [0,64]
Given in the question that,
the maximum number of people that can seat on the ferris wheel = 64
the minimum number of people that can seat on the ferris wheel = 0
Function to calculate the amount of money
M(p)=2p
Value of p can be any integer from zero to 64 so the domain of this function is
0 ≤ x ≤ 64
