Answer:
The length of the ramp is at least 17.2 feet
Step-by-step explanation:
See attachment for the appropriate diagram.
The length of the ramp is represented with z
So, we have:
Required
Find z
To find z, we make use of sine formula:
Make z the subject
So:
<em>The length is at least 17.2 feet</em>
The probability when x is greater than 120 is 0.0367. Then the correct option is D.
<h3>What is a normal distribution?</h3>
The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The mean is 95 and the standard deviation is 14. Then the probability when x > 120 will be
The z-score will be
z = (120 - 95)/ 14
z = 1.7857
Then the probability will be
P(x > 120) = P(z > 1.7857)
P(x > 120) = 1 - P(x<120)
P(x > 120) = 1 - 0.96293
P(x > 120) = 0.0367

Answer:
3) 36
2) 55
Step-by-step explanation:
We have to place the numbers in order from least to greatest.
3) 23, 26, 26, 32, 32, 36, 50, 52, 52, 52, 59,
4) 40, 42, 49, 54, 62, 67, 67, 70, 95
The more is the the difference between the lowest and highest values.
95-40=55
Answer:
2
Step-by-step explanation:
g(x) = 1/2x - 1
g(6= 1/2*6-1= 3-1= 2
