Answer: 3.65
Step-by-step explanation:
This question is asking basically what is 50% or 1/2 of 7.3.
Let's expand the number 7.3
Then, we end up getting 7.30.
We have to find 1/2 of 7.30.
of 7.30 =

Smart TV, Smart Navigation in cars
Step-by-step explanation:
Smart TV :
Smart navigation in cars:
A. y (x + 4) (x + 5)
Answer:
D. y =
Step-by-step explanation:
The solutions to this graph (meaning when y equals 0 or when the graph crosses the x-axis) are 4 and 5.
The only answer choice that has the solutions 4 and 5 when you factor it out is D.
Here's the proof:
Factors of 20: - 5 & -4
Sums that add up to -9: -5 + (-4)
(factor the first two terms and the last two terms separately)
(x - 5) (x - 4)

b)the number of reflexive and symmetric relations on S
Answer:
The number of reflexive relations on S is 64.
The number of reflexive and symmetric relations on S is 8.
Step-by-step explanation:
Consider the provided set S = {a, b, c}.
The number of elements in the provided set is 3.
Part (a) the number of reflexive relations on S
To calculate the number of reflexive relation on S we can use the formula as shown:
Total number of Reflexive Relations on a set:.
Where, n is the number of elements.
In the provided set we have 3 elements, so substitute the value of n in the above formula:
Hence, the number of reflexive relations on S is 64.
Part(b) The number of reflexive and symmetric relations on S.
To calculate the number of reflexive and symmetric relation on S we can use the formula as shown:
Total number of Reflexive and symmetric Relations on a set:.
Where, n is the number of elements.
In the provided set we have 3 elements, so substitute the value of n in the above formula:
Hence, the number of reflexive and symmetric relations on S is 8.

Find the proportion of selling times in the sample that are less than 20 days claims that it can sell a detached, residential house faster than any other realty company.
Answer:
0.35
Step-by-step explanation:
Given the data:
Selling Time___ Frequency
0 10____________3
10 20__________ 4
20 30__________ 6
30 40__________ 4
40 50__________ 3
Proportion of selling time in sample above that are less Than 20 days :
Taking the sum of the frequency :
Hence, total frequency = (3 + 4 + 6 + 4 + 3) = 20
Selling time which is less Than 20 days :
(0 - 10) = 3
(10 - 20) = 4
Total = (3 + 4) = 7
Proportion = selling time less Than 20 days / total frequency
= 7 / 20
= 0.35
