Answer:
a. P(x=0)=0.2967
b. P(x=1)=0.4444
c. P(x=2)=0.2219
d. P(x=3)=0.0369
Step-by-step explanation:
The variable X: "number of meals that exceed $50" can be modeled as a binomial random variable, with n=3 (the total number of meals) and p=0.333 (the probability that the chosen restaurant charges mor thena $50).
The probabilty p can be calculated dividing the amount of restaurants that are expected to charge more than $50 (5 restaurants) by the total amount of restaurants from where we can pick (15 restaurants):
Then, we can model the probability that k meals cost more than $50 as:
a. We have to calculate P(x=0)
b. We have to calculate P(x=1)
c. We have to calcualte P(x=2)
d. We have to calculate P(x=3)

Since it is negative you go behind the .
so you would go 5 spaces behind the point
Answer:
59 °F
Step-by-step explanation:
Put the given number in the formula and do the arithmetic.
F = (9/5)(15) +32 = 27 +32 = 59
The temperature in degrees Fahrenheit is 59.
9,500 is 15% less than the original price.
So it must be 85% of the original price.
£9,500 = 0.85 P
Divide each side by 0.85 :
P = £9,500 / 0.85 = £11,176.47
Answer:
false
