Answer:
WXZ and YXU
Step-by-step explanation:
All verticle angles are opposite to each other. Look at it like an X, verticle angles would be the top and bottom or the side and other side.
Answer:
<h3>20</h3>
Step-by-step explanation:
Standard deviation of the mean is expressed as:
SM = s/√n
s is the standard deviation of all invoices
n is the sample size of the invoiced
Given
s = $200
n = 100
Required
Standard deviation of the mean
Substitute the given parameters into the given equation
SM = 200/√100
SM = 200/10
SM = 20
Hence the standard deviation of xbar is 20
Answer:
y=x-1
Step-by-step explanation:
Gradient=1
Rise/run=1/1=1
y=x+c
y intercept=-1
y=x-1
5n = 10^2
n = 20 Because 5 × 20 = 100
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
