Answer:

\underline{ \underline{  \pink{\large{ \tt{ \: S \:T \: E \: P \:  -  \: BY \:  -  \: S \: T \: E \: P \: \:  E\: X\: P \: L \: A \:N\: A \: T \: I \: O \: N}}}}}:

Q. Find the range and coefficient of range of the data :

  • 100 , 200 , 400 , 600 , 900

⇾ Solution :

  • largest value ( L ) = 900 & smallest value ( S ) = 100

We know , Range is the difference between the largest and smallest value. By definition ,

1. Range = Largest value - Lowest value = 900 - 100 = \boxed{ \sf{800}}

2. Coefficient of range =\large{ \tt{ \frac{L - S}{L + S} =  \frac{900 - 100}{900 + 100 }  =  \boxed{ \tt{0.8}} }}

Q. If f ( x ) = 9x - 8x and x belong to { 0 , 4 , 3 ,5 }. Find the range.

⇾ Solution:

When x = 0 , f ( 0 ) = 9 × 0 - 8 × 0 = 0

When x = 4 , f ( 4 ) = 9 × 4 - 8× 4 = 4

When x = 3 , f ( 3 ) = 9 × 3 - 8 × 3 = 3

When x = 5 , f ( 5 ) = 9 × 5 - 8 × 5 = 5

  • Range = { 0 , 4 , 3 , 5 )

Thomas works as a salesperson on Saturday and Sunday at the verizon store he is payed 46.50 each day and for every smart phone h
Triss [41]
So he is paid 46.5 flat  every day
he earns 5% of each smart phone he sells
at the time of the problem, smart phones sell for 70 so he earns 5% or 70 or 5/100 of 70 or 1/20 of 70 or 70/20 or 7/2 or 3 and 1/2 or $3.50 per phone he sells

so pay must be at lease 150 so
pay=46.5+ (# of phones times 3.50)
150<u><</u>46.50+(number of pones times 3.50)
solve for number of phones
subtract 46.5 from both sides
103.5<u><</u>(number of phonest imes 3.5)
divdie both sides by 3.5
29.57<u><</u>number of phones
round up since can't sell a fraction of a phone
30
he has to sell at leas 30 phones

Write the letter for each expression in the box under the correct category in the table.
Ad libitum [116K]

Answer:

a) 9+(-3) + (-2)  = 9 -5 = 4> 0  ⇒  Positive Sum

b) -12 +1 +11  = -12  +12 5 =  0  ⇒  Zero Sum

c) -3 +8 + (-4)  = -7 + 8 -5 =-1 <  0  ⇒ Negative Sum

d)  -4+9+(-10) = 9 -14 = -5 <  0  ⇒ Negative Sum

e) 3+(-2) + (-4)  = 3  -6= -3 <  0  ⇒ Negative Sum

f) 2 + (-4) + 2  = 4 -4 =  0  ⇒  Zero Sum

Step-by-step explanation:

Positive Sum is defined as the condition in which the Sum of total of gains and losses is GREATER THAN ZERO.

Zero Sum  is defined as the condition in which the Sum of total of gains and losses is EQUAL TO ZERO.

Negative Sum is defined as the condition in which the Sum of total of gains and losses is LESS THAN ZERO.

Now, here

a) 9+(-3) + (-2)  = 9 -5 = 4> 0  ⇒  Positive Sum

b) -12 +1 +11  = -12  +12 5 =  0  ⇒  Zero Sum

c) -3 +8 + (-4)  = -7 + 8 -5 =-1 <  0  ⇒ Negative Sum

d)  -4+9+(-10) = 9 -14 = -5 <  0  ⇒ Negative Sum

e) 3+(-2) + (-4)  = 3  -6= -3 <  0  ⇒ Negative Sum

f) 2 + (-4) + 2  = 4 -4 =  0  ⇒  Zero Sum
