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
1/5 and 3/5
Hope this helps!
She should by the one that is written as 375/1000 inches because if Trudy needs a nail that measures 0.375 she should get that one and also .375 and 375/1000 is really the same thing. hope it helps
Answer:
the answer would be 20
Step-by-step explanation:
so if 18-(-2)=?
two nwgatives make a positive. So the equation would turn into 18+2=20
Im not 100% if this is right but htis is how I was taught to do it.
Answer is $155 for the job
Step by step
You can use y intercept formula for this one.
Y = mx + b
Y = Dollars earned, what you are looking for.
M= rate per hour (27)
X = hours worked (5)
B = flat rate (20)
y = (27) (5) + 20
y = $155
Problem solved!
