Answer:
(a)
(b): Cell industry
(c) See Explanation
Step-by-step explanation:
Given (Missing from the question)
Solving (a) Show the frequency and percent frequency.
The percentage frequency is calculated by:
So. we have:
-- Bank
--- Cable
--- Car
--- Cell
--- Collection
The table becomes:
Solving (b): The industry with the highest complaints
From the above table, the highest frequency is 60 and this represents the number of complaints of Cell industry.
Hence, the cell industry has the highest number of complaints
Solving (c): Comment
The percentage frequency table shows that the industry with the highest number of complaints is the cell industry (at 30%) and the industry with the least is the banking industry (at 13%)
The answer is the fourth choice , I think
Answer:
AB = JK = 49
Step-by-step explanation:
Since ABC = JKL
We know the length of AB has to equal the length of JK.
AB = JK
14x+7 = 5x+34
Subtract 5x from each side.
14x-5x +7 = 5x-5x+34
9x+7 = 34
Subtract 7 from each side
9x+7-7 = 34 -7
9x = 27
Divide each side by 9.
9x/9 = 27/9
x =3
AB = 14x+7
Substitute x=3
14(3) +7
42+7
AB = 49
Step-by-step explanation:
5x can also be written as " -3x + 8x " so:
Using the distributive property:
Then again, using the distributive property (but in reverse):
The two numbers that the middle term should be split into in order to factor can be found by listing out pairs of factors for the product of the last term and the coefficient of the first term, and using the two factors whose sum is the middle term.
For eg (because that was a bit text heavy):
The product of the last term and the first coefficient (1 * (-24)) is -24
the factors of -24 include (and their sum)
-1, 24 (23)
1, -24 (-23)
-2, 12 (10)
2, -12 (-10)
-3, 8 (5)
3, -8 (-5)
-4, 6 (2)
4, -6 (-2)
The middle coefficient is 5 and the sum of the factors -3 and 8 are 5, so split 5x into -3x + 8x to be able to factor how I showed before.
