Answer:
x = 52.0
Step-by-step explanation:
Reference angle = 68°
Length of side Opposite to reference angle = x
Adjacent length = 21
Apply the trigonometric function, TOA, which is given as:
Tan 68° = Opp/Adj
Substitute
Tan 68° = x/21
21 × Tan 68° = x
51.9768238 = x
x = 51.9768238 ≈ 52.0 (approximated to nearest tenth)
Solution
621 ÷ 7 = n
621 ÷ 7 = <span>88.7142857143
</span>
n = 88.7142857143
Answer = 88.7142857143
Rounded = 88.7
Answer:

Step-by-step explanation:
To find what number 96 is 44% of is we can use the formula:

Just substitute 94 and 44 into the equation:


Or rounded,

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)
