Answer:
Well the original price would be $44
Step-by-step explanation:
So make an equation
Lets make X stand for the price before the deduction
so x-x(0.3)=30.80
Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change
Now just solve the equation
You’ll get 44.
We know, 1 m = 100 cm
Multiply both sides by 7,
7 m = 100 * 7 = 700 cm
In short, Your Answer would be 700 cm
Hope this helps!
Answer:
-4/1 or -4
Step-by-step explanation:
A reciprocal is found by switching the numerator and denominator. So if we ignored the negative sign and found the reciprocal of 1/4, it is 4/1. Now, if you add the negative sign, you get -4/1. If you simplify, you get -4. I'm not really too sure on my answer so you can ask more than one person. I hope you get the help you need!
Answer:
It might be the second choice I am not very sure but it might be.
Step-by-step explanation:
Not very good at math so you should probably wait for the second answer!
This is a Poisson Distribution
Average over 3 months = 2
Average over 1 month = 2/3
Average over 2 months = 4/3 = λ
More than four heavy rainfalls means 5, 6, 7,…
P(5) = (e^-λ x λ^5)/5! = 0.009257
P(6) = 0.002057
P(7) = 0.000392
P(8) = 0.000065
P(9) = 0.000010
P(10) = 0.000001
P(more than 4 heavy storms) = 0.01178 (4sf)
