Answer:
30 seconds
Step-by-step explanation:
210 divided by 7 is 30
Answer:
Step-by-step explanation:
<u>Total frequencies:</u>
Median group is the containing the middle - 25th and 26th frequencies. This is the 11-15 interval.
<u>Estimated median formula:</u>
- Estimated Median = L + ((n/2) − B)/G* w, where
- L - lower class boundary of the group containing the median = 10.5
- n - total number of values = 50
- B - cumulative frequency of the groups before the median group = 6 + 15 = 21
- G - frequency of the median group = 20
- w - group width = 5
<u>Substitute values and work out the number:</u>
- Estimated Median = 10.5 + (50/2 - 21)/20*5 = 11.5
Which numbers are you doing?
85c - 0.5(85c) = 161.5
85c - 4.25c = 161.5
80.75c = 161.5
c = 161.5 / 80.75
c = 2............so she needs express proofreading
==================
x - 3 < -7 x + 5 > = 8
x < -7 + 3 x > = 8 - 5
x < -4 x > = 3

Konichiwa~! My name is Zalgo and I am here to help you out today. The factorization of your equation is 4 (2a+b) (2a-b). If you do not understand this, it means 4 multiplied by 2a+b which is also multiplied 2a-b.
I hope that this helps! :P
