Step-by-step explanation:
Answer:
Hence, the probability that seven or more of them used their phones for guidance on purchasing decisions is 0.7887
Step-by-step explanation:
We are given the following information in the question:
We treat people using phones in the store for guidance as a success.
P(People use phone for guidance) = 57% = 0.57
Then the number of people follows a binomial distribution, where
Formula:

where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 14 and x = 7
We have to evaluate:

Hence, the probability that seven or more of them used their phones for guidance on purchasing decisions is 0.7887

Answer:40
Step-by-step explanation:first you do 24 divided by 8 because you have to follow order of operations and you get 3 then next you do 43 minus 3 to get 40 as your answer
Answer:
The answers are that a = -5 and b = 1
Step-by-step explanation:
In order to find A and B, we first need to find the equation of the line. We can do this by using two ordered pairs and the slope formula. For the purpose of this activity, I'l use (0, 5) and (-3, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 5)/(-3 - 0)
m = 6/-3
m = -2
Now that we have this we can model this using point-slope form.
y - y1 = m(x - x1)
y - 5 = -2(x - 0)
y - 5 = -2x
y = -2x + 5
Now that we have the modeled equation we can use the ordered pair (a, 15) to solve for a.
y = -2x + 5
15 = -2(a) + 5
10 = -2a
-5 = a
And we can also solve for b using the ordered pair (2, b)
y = -2x + 5
b = -2(2) + 5
b = -4 + 5
b = 1
