if you add 2 negatives together you get a smaller number,(farther away from zero) therefore, -3+(-1)= -4
Answer:
24.2% decrease
Step-by-step explanation:
The distance Javi must ride changed by ...
1.25 -1.65 = -0.40 . . . miles
The ratio of that to the original distance is ...
-0.40/1.65 × 100% ≈ -24.2%
The distance decreased by 24.2%.
Answer:
The probability is of 0.1404 or 14.04%.
Step-by-step explanation:
The Poisson Distribution formula is given by:
Where:
,
is Euler's constant,
is the number of successes of which we're trying to calculate the probability of occurring.
In this exercise we have that:
.
Replacing in the formula we get:
Therefore the probability of three customers shopping at the store in an hour is of 0.1404 or 14.04%.
