26 percent of 200 is 52 :)
Answer:
see below
Step-by-step explanation:
To check your solution , plug the value of k into the original equation
6(7k-10) =24
k=2
6(7*2-10) =24
6(14-10) =24
6(4) =24
24=24
The solution is correct

Answer:
0.0323 = 3.23%. Is unusual
Step-by-step explanation:
Using the normal distribution we can find z value with the mean and standard deviation as follows. x is the value we want to know its probability
z = (x - mean)/standard deviation
z = (5-8.54)/1.91
z = -1.85
Using z tables for normal distribution, for z = 1.85, we have an area under the curve of 0.9677. Since we want to know the probability for 5 minutes or less, we have to substract from
p = 1- 0.9677
p = 0.0323
An event with a probability less than 5% is considered unusual.
