Answer:
50%, 68.26%, 95.54%
Step-by-step explanation:
Let X be the day care costs
X is N(10000, 2000)
Since normal distribution is symmetrical about the mean we get
above 10000, exactly 50% of day care cost would be .
Between 8000 and 12000,
=
Between 6000 and 14000
%
Ur missing numbers are -2, 6, and 36
Since the center point is (-2,6), the numbers are reversed in the equation to: (x+2) or(x- -2) and (y-6)
The radius is 6 units so u square it to get 36
Answer: 1/36
Step-by-step explanation:
Calm down, I'm here to help! You might want to watch some videos on how to solve negative powers, but it's simpler than you think.
An exponent expression is formatted as a^b.
If "b", the exponent, is negative, then you can solve expression like this:
1/a^-b
By writing -b, I mean the opposite of b. For example, the opposite of -2 is 2.
Let's use that rule to solve this problem.
1/6^-(-2)
1/6^2
1/6*6
1/36
There you go! It's not too scary now, is it? Let me know if you'd like me to link some resources!
Answer:
Kelly walks 4/5 of a mile each day.
After 3 days, Kelly walks a distance: D = 3 x 4/5 = 12/5 = 2.4 miles
Hope this helps!
