Answer:
this would be B.
Step-by-step explanation:
it crosses the y axis at positive 3. so has to be +3. this leaves b and c, it is a negative slope so it is Y= -2x+3.
Answer:
7 or 
Step-by-step explanation:
Each triangle has the surface area of 1.5, because 1
3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5
4 = 6. The square in the middle has the surface area of 1 because 1
1 = 1. So you would get 7.
Answer:
Step-by-step explanation:
find the attachment showing std normal curve symmetrical about y axis.
Equal probabilities on either side of the mean thus the total probability to the right of mean is 0.50
From the table we can find that
a) P(Z>2.5) = 0.5- area lying between 0 and 2.5
= 0.5-0.4938 =0.0062
b) P(1.2<z<2.2) = F(2.2)-F(1.2)
= 0.9861-0.3849
=0.6012
Answer:
3x+12
Step-by-step explanation:
distribute
Answer:
6 m
Step-by-step explanation:
The volume of a cone is found by
, so we can plug the values in to get 6pi * r^2 / 3 = 72pi, or 6pi * r^2 = 216 pi, so r^2 = 36 and the radius is 6 m.
