Answer:
andioop
Step-by-step explanation:
Step-by-step explanation:
the one on the left (b)
y= mx+b
at x= 0 y = -2
then b= -2
at x= -1 y= 1
1= -m -2
m= -3
y= -3x -2
......
the one on the right side (d)
at x= 2 y = 1
at x= 4 y = 2
1= 2m+b
2= 4m +b
subtract
1= 2m
m= 1/2
y= 1/2 x
The z-score for 45cm is found as follows:
Reference to a normal distribution table, gives the cumulative probability as 0.0099.
Therefore about 1% of newborn girls will be 45cm or shorter.
Answer:
166 m^2
Step-by-step explanation:
The enclosing rectangle is 9m by 29m, so is 261 m^2. From that, the white space of 5m by 19m = 95 m^2 must be subtracted. The result is that the shaded area is ...
261 m^2 -95 m^2 = 166 m^2
