Sonam sold two cars for nu. 55055 each. one has gained him 16% while the other made him loss 16%. how much does he loss or gain
statuscvo [17]

Answer: Total Loss or Gain = $0

<u>Step-by-step explanation:</u>

Gain:   $55,055 (1 + 0.16)

        = $55,055 (1.16)

        = $63,863.80

Profit = $8,808.80

Loss:   $55,055 (1 - 0.16)

        = $55,055 (0.84)

        = $46,246.20

Loss = -$8,808.80

Profit + Loss

= $8,808.80 - $8,808.80

= 0

A pet store owner, Byron, needs to determine how much food he needs to feed the animals. Byron knows that he needs to order the
Brums [2.3K]

Answer:

He needs to buy 120 packages of dod food.

Step-by-step explanation:

b - bird food

h - hamster food

d - dog food

c - cat food

b + h + d + c = 600

b = h (bird food is the <em>same</em> as hamster food)

b = 4 d (bird food is <em>4 times</em> dod food)

c = d/2 (cat food is <em>half</em> dog food)

Total of packages ordered.

b + b + d + c = 600

4d + 4d + d + d/2 = 600

4 d + 4 d + d + d = 600. 2

10 d = 1.200

d= 120 .........the amount of dog food packages.

Shanti wrote the predicted values for a data set using the line of best fit y = 2.55x – 3.15. She computed two of the residual v
svet-max [94.6K]
<span>Residual value is the difference between the observed value of the dependent variable (y) and the predicted value (ŷ) in a data set.

i.e. Residual value = given value - predicted value

From the table, the residual value corresponding to a has 4.1 as the given value and 4.5 as the predicted value.
Therefore, a = 4.1 - 4.5 = -0.4

Similarly, </span><span>the residual value corresponding to b has 7.2 as the given value and 7.05 as the predicted value.
Therefore, b = 7.2 - 7.05 = 0.15
</span>
Therefore, a = -0.4 and b = 0.15

Let a set of n elements. 
We can find n! (factorial) of the n element. 
However, combination of the element lead to less than n! possibilities. 
(combining like adding or multiplying)
So the proposition is false.
