Answer:
0.9209
Explanation:
For a normally distributed random variable, the only way to find areas is using the z score. The z score is given by the equation:
Where μ is the mean, σ is the standard deviation and x is the raw score to be measured.
The area under the standard normal curve that lies between the interval z=-2.73 and z=-1.39
From the z table, Area between -2.73 and -1.39 = P(z < -1.39) - P(z < -2.73) = 0.0823 - 0.0032 = 0.0791
Since the Area between -2.73 and -1.39 is 0.0791, the are outside the interval = 1 - 0.0791 = 0.9209
Answer: the company has to increase its revenue in 33.33%
Explanation:
Let's see the companie's goal is to reach 64 million which is the double of 32 million.
the company increases its revenue by 50% which means that the company has increased it revenue in 16 millions.
32 million * 50/100 = 16 million
Now the the first year revenue is 32 million plus 16 million = 48 million
64 million - 48 million = 16 million (amount in which the company has to increase its revenue to reach 64 million)
with a simple three rule
48 million ----- 100%
16 million -------X
X= 1600/48 X= 33.33%
About 6,271 people had viewed the video once it had been online for 20 days. The correct option is C.
<h3>What is exponential equation?</h3>
Exponential equation is the equation in which the exponent or part of exponents used as variables.
where, x is the number of days, given that x = 20
Putting the values in the equation
Thus, the correct option is C, 6,271.
