Answer:
A.
Sample 1 mean: 6.375
Sample 2 mean: 6.375
Sample 3 mean: 6.625
B.
Range of sample means: 0.25
C.
The first and last boxes should be checked, as they are true.
Step-by-step explanation:
To calculate the mean you must add all of the numbers together and then divide the sum by the quantity of numbers. Ex: 3+7+8+3+7+9+6+8 = 51.
51/8 = 6.375.
Answer:
x=333.33%
Step-by-step explanation:
hello
you can resolve this by using the rule of 3,let´s see
75 oranges =100%
250 oranges = x%?
75 oranges* x%=250 oranges *100%

x=333.33%
Have a great day.
Answer:
t = (C - 3*A)/B + 3
Step-by-step explanation:
Given in the question that,
the speed with which canoe travelled for first 3 hours = A
the speed with which he travelled for any and all time thereafter = B
As we do not know the values of A, B, or C, so the answer will be an expression for C in terms of A and B.
<h3>Formula to use</h3>
distance = speed x time
C = A*3 + B*(t-3)
Rearranging and solving for t
C - (A*3) = B*(t-3)
C - (A*3) = Bt - B3
C - (A*3) + B3 = Bt
t = C - (A*3) + B3 / B
or
t = (C - 3*A)/B + 3
Answer:
14/9 or 1.555556
Step-by-step explanation:
1) Simplify 1 + 1/3 to 4/3.
(4/3)^2 - 2/9
2) Use Division Distributive Property: (x/y)^a = x^a/y^a.
4^2/3^2 - 2/9
3) Simplify 4^2 to 16.
16/3^2 - 2/9
4) Simplify 3^2 to 9.
16/9 - 2/9
5) Simplify.
14/9
(Decimal form: 1.555556)
Thanks, Eddie
All i know is that both of them are parallel
i think for the first one its 6
hope this helps
