Answer:
the "acceleration" is -15m/s (it's negative because it is slowing down, not speeding up[it might just be a positive 15m/s if it is called deceleration and not acceleration])
Step-by-step explanation:
30m/s (starting speed)/2 (the number of seconds it took to stop from 30m/s
Answer:
Length of rectangular lawn =72 meters
Breadth of rectangular lawn =18 meters
Perimeter of rectangle =2(Length+Breadth)
So, Perimeter of rectangle =2(72+18)=2(90)=180 meters
If three shrubs can be planted in a meter of hedge.
Then, Number of shrubs planted in whole perimeter will be=3×180=540

Answer:
Step-by-step explanation:
Given that the Acme Company manufactures widgets, which have a mean of 60 ounces and a standard deviation of 7 ounces
We know that 95% of the area lie between -2 and 2 std deviations from the mean.
i.e. Probability for lying in the middle of 95%
Z score 
Between 46 and 74 oz.
b) Between 12 and 57
convert into Z score

P(-6.86<z<-0.43)
=0.5-0.1664=0.3336
c) X<30 gives Z<-4.83
i.e. P(X<30) =0.00
Answer:
The altitude will begin at angle D and go in a straight line downwards.
The perpendicular bisector will be a straight line going from one corner to the other corner, not directly downwards.
