Answer:
They are perpendicular lines
Step-by-step explanation:
If one line has slope -8 and the other one has slope 1/8, they must be perpendicular to each other because the condition for perpendicular lines is that the slope of one must be the "opposite of the reciprocal of the slope of the original line."
the opposite of -8 is 8 , and the reciprocal of this is 1/8
Answer: 1/2
Step-by-step explanation:
First step: we will use Tchebyscheff's theorem. The theorem can help us to explain random variables with finite variance as well as mean.
P (|Y-u| < or equals to 1) | > or equals to 0.75
= 1 - 1/2
Therefore, w= 2
Step 2: we use Tchebyscheff's inequality, which is:
= -2¶ + u < y < 2¶ + u
Therefore, we have; --2¶ + u
= 1 + u
1= K¶
¶ = 1/2.
Please take note that ¶ is represented as sigma symbol.
Since I can't get the symbol here with me. Also the u repres represent 'micro' symbol
In perspective this looks tricky but really its no ;) just follow it slowly.
110.25 is your total cost
3 is how many you bought.
So doing division 3/110.25= 36.75
CHECK: 36.75 + 36.75 + 36.75 = 110.25.
Hope this helps.

Step-by-step explanation:
On calculators, anytime we're doing a fraction problem and we use calculators, It doesn't give us the fractions all it gives us is decimals, but i finally got the fraction for you. hope this helped
Make sure nobody copied and pasted my answer because i would be WILLING TO report their answer for copying and pasting
Answer:
50.40
Step-by-step explanation:
7 hours and 20 minutes times 7= 50 hours and 40 minutes
And then you have to change it into a mixed number and it is 50.40
