Answer:
Step-by-step explanation:
3 × (4 + 5) - 6 = 21
4 × (3 + 2) - 8 = 12
Answer: see below
<u>Step-by-step explanation:</u>
I'm not sure exactly what you are asking for but here is what the box plot tells you:
Minimum is 17 items.
Q1 (Lower Quartile) is 22 items. So, 25% of the customers bought 22 items.
Q2 (Median) is 32 items. So, 50% of the customers bought 32 items.
Q3 (Upper Quartile) is 35 items, So, 75% of the customers bought 35 items.
Maximum is 62 items.
The data is "heavier" on the right so it is skewed left.
Range is 62 - 17 = 45
IQR (Interquartile range) is Q3 - Q1 = 35 - 22 = 13
Answer:
Senny: 45 mph; Farouk: 35 mph
Step-by-step explanation:
Their combined speed is 520 mi/(6.5 h) = 80 mi/h. Senny's speed is half the sum of this and the difference of 10 mi/h:
... (80 mi/h + 10 mi/h)/2 = 45 mi/h
Farouk's speed is 10 mi/h less:
... 45 mi/h - 10 mi/h = 35 mi/h

<em>Comment on Sum and Difference Problems</em>
If two numbers <em>a</em> and <em>b</em> have a sum of <em>s</em> and a difference of <em>d</em>, you can write equations ...
Adding these two equations gives ...
... 2a = s + d
Dividing this by 2 gives
... a = (s + d)/2 . . . . . . the formula we used above
Answer:
your answer is going to be (-2,2)
Step-by-step explanation:
Answer: 3x-1
Step-by-step explanation:
3(x-2)+5 you distribute the 3 to (x-2) then you get 3x-6+5 then you add the -6+5 which is one... so the answer is 3x-1
