Answer:
3 seconds
Step-by-step explanation:
when h=7 ft
-16t²+49t+4=7
-16t²+49t-3=0
16t²-49t+3=0
16t^2-48t-t+3=0
16t(t-3)-1(t-3)=0
(t-3)(16t-1)=0
t=3,t=1/16
t=1/16 seconds is the time when it just started.
so reqd. time=3 seconds.
Answer:
-2
Step-by-step explanation:
From the given price function, we have;
(a)
(b) The point elasticity of demand is 0.0256<u>;</u><u> </u><u>i</u><u>nelastic demand</u>
(c) $46.6
(d) Increase
<h3>How can the elasticity of demand be found?</h3>
a. The given function is presented as follows;
Differentiating the above function with a graphing calculator and setting q = 150 gives;
b. The point elasticity of demand is given by the formula;
When q = 150, we have;
P = 50
Which gives;
The point elasticity of demand, <em>E </em>= <u>0.0256</u>
- The <u>demand is inelastic</u> (less than 1) when the quantity demanded is 150 units
c. If the quantity demanded decreases from 150 to 140 units, we have;
Which gives;
p = 46.6
- The price when the quantity demanded decreases to 140 is <u>$46.6</u>
d. Given that increase in price, from 46.6 to 50, increases the quantity demanded from 140 to 150, therefore;
- The manufacturer should<u> increase the price</u>, <em>p </em>to increase the revenue, <em>R</em>.
R = p × q

Answer:
0.1732 = 17.32% probability exactly 24 residents own a home.
Step-by-step explanation:
For each resident, there are only two possible outcomes. Either they own a home, or they do not. The probability of a resident owning a home is independent of any other resident. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
78% of residents in Summerville own a home.
This means that
30 residents are randomly selected:
This means that
Find the probability exactly 24 residents own a home.
This is P(X = 24).
0.1732 = 17.32% probability exactly 24 residents own a home.
