Step-by-step explanation:
Let the number be x
2 more than a number = x + 2
Answer:
YEEEEEEEEEEEEEEEEEEETTTTTTTTTTTTTTT
Step-by-step explanation:
The smallest number is 67/1000, then 0.672, then 68%, then 0.7, and the largest is 0.7
Vertex form is:
f(x) = -5(x+10)^2 + 508
Answer:
0.9256
Step-by-step explanation:
Given that a convenience store owner claims that 55% of the people buying from her store, on a certain day of the week, buy coffee during their visit
Let X be the number of customers who buy from her store, on a certain day of the week, buy coffee during their visit
X is Binomial (35, 0.55)
since each customer is independent of the other and there are two outcomes.
By approximation to normal we find that both np and nq are >5.
So X can be approximated to normal with mean = np = 19.25
and std dev =
Required probability = prob that fewer than 24 customers in the sample buy coffee during their visit on that certain day of the week
= (after effecting continuity correction)
= 0.9256
