We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
Answer: Probability of randomly selecting a member who likes to cook or likes to sew = 58%
Step-by-step explanation:
Since we have given that
Probability of a randomly selecting a member who likes to cook=P(C) = 42%
Probability of a randomly selecting a member who likes to sew =P(S)= 23%
Probability of a randomly selecting a member who likes to both cook and sew

As we know the "Probability rules " :

So, Probability of randomly selecting a member who likes to cook or likes to sew = 58%
Answer:
- <em> 15</em>
- <em> 42,250</em>
Step-by-step explanation:
The given function is,

where,
P = the total production of apples,
x = the number of trees added.
As the quadratic function has a negative leading coefficient, so it will open downward and at the vertex the value of function is maximum.
The vertex will be at 
The value of the function will be maximum at,

Putting the values,

So at x=15 or for 15 number of trees the production will be ,maximum.
Putting x=15 in f(x) will yield the maximum production of apples.

H=-5(t^2 - 16t)
H=-5(t^2 - 16t +64)+320
H=-5(t-8)^2 +320
Vertex is at (8, 320)
The max height is 320 m.
