The length of the first two sides of a triangle must be greater than the length of the last side. If the longest length were 18, the first two sides would be too short. 36-18=18, 18 is equal not greater than 18 which means the sum of the first two sides are too short.

X +y=13

One hosta cost $8 and one pot of ivy cost $3.

Step-by-step explanation:

Let,

Hostas = x

Pot of ivy = y

According to given statement;

7x + 3y = 65 Eqn 1

3x + 3y = 33 Eqn 2

$Subtracting\ Eqn\ 2\ from\ Eqn\ 1\\(7x+3y)-(3x+3y)=65-33\\7x+3y-3x-3y=32\\4x=32\\Dividing\ both\ sides\ by 4\\\frac{4x}{4}=\frac{32}{4}\\x=8\\$

Putting value of x in Eqn 1;

$7(8)+3y=65\\56+3y=65\\3y=65-56\\3y=9\\Dividing\ both\ sides\ by\ 3\\\frac{3y}{3}=\frac{9}{3}\\y=3$

One hosta cost $8 and one pot of ivy cost $3.

P(z=1.85) what is the area to the left of z= 1.85

0.84(because 20% of the observations are about 0.84)
You've found the 80th percentile! The 80th percentile of the standard normal distribution is 0.84. That's because 80% of the observations fall below 0.84. (Note: The 80th percentile of every normal distribution is 0.84 times the standard deviation above the mean.)
