Answer:
The height of the beam is:
Step-by-step explanation:
The radius of the tunnel is r = 15 feet
The distance of the beam from the center of the tunnel is:
We have a right triangle, where:
- The Hypotenuse is 15 feet
- One side is 9 feet
- The other side is the height of the beam
Let's use Pythagoras theorem.
Therefore, the heigh of the beam is:

Table H
for y to be a function of x, every x input value has to map to one and only 1 output y value
at table H, x = -0.2 maps to both 5.8 and 8.1 (both ends of the table)
so table H is not y as a funtion of x
Answer:
x = - 36
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 27 when x = 12, then
k = yx = 27 × 12 = 324, thus
y = ← is the equation of variation
When y = - 9, then
- 9 = ( multiply both sides by x )
- 9x = 324 ( divide both sides by - 9 )
x = - 36
Answer:
ī=80; s = 10
Step-by-step explanation:
When the standard deviation is from a finite group it is denoted by s. The number of transactions from an atm are countable in a day. So the standard deviation will be represented by s.
and ī represents the mean.
The other choices are incorrect because mean is usually represented by a bar over the alphabet such as x.
a simple alphabet does not denote the mean of the sample or population.
