Answer:
7.4825 km or 7.48 km (rounded to nearest hundredth)
Step-by-step explanation:
<u>Ranch's measurements rounded up to the nearest hundredth:</u>
1st measurement =
= 7.75 km
2nd measurement =
= 7.25 km
3rd measurement = 7.3(recurring) = 7.33 km
4th measurement = 7
= 7.60
<u>The average of the four measurements is:</u>
(7.75 + 7.25 + 7.33 + 7.60) ÷ 4 = 7.4825 km or 7.48 km (rounded to nearest hundredth)
Answer:

--- Variance
Step-by-step explanation:
Given

Solving (a): Calculate the mean.
The given data is a grouped data. So, first we calculate the class midpoint (x)
For 51 - 58.

For 59 - 66

For 67 - 74

For 75 - 82

For 83 - 90

So, the table becomes:

The mean is then calculated as:



-- approximated
Solving (b): The sample variance:
This is calculated as:

So, we have:


-- approximated
Answer: The answer is two football players pushing a tackling sled because obviously they are going in the same direction. So yeah your answer is B 100% sure!
No, the tangent line needs to be against the circle from where it leaves. This is just a straight up right angle.
Answer:
the answer would be n+5
Step-by-step explanation:
5n is the same as saying 5 multiplied by n
n +5 would equal the same number
for example if n=2 then 5+2=7
and if we used n+5 it would be 2+5=7
and if you plugin n=2 for all the equations the only correct one is N+5
