The first equation is x + y = 29, and the second is 5x + 2y = 100.
To calculate the mean absolute deviation of
1,2,3,4,5,6,7
, we start by finding the mean;
(1+2+3+4+5+6+7) =28/7
= 4
. Next, we determine the absolute differences of each data point from the mean (x-μ)
= -3,-2,-1,0,1,2,3
. The absolute values are 3,2,1,0,1,2,3
. Now we compute the mean of these absolute differences,
3+2+1+0+1+2+3 = 12
= 12/7
= 1.7143
. Thus, the mean is 4, and the Mean absolute deviation comes out to be 1.7143
You have two kinds of data $ and %!
Align them properly and perform cross multiplication.
16% corresponds to $38 as
100% corresponds to $x
Following this, x = (38*100)/16 = $237.5, which is the original price before the discount.
Approximate length of wire ≈ 193 ft (to the nearest foot).
Answer:
The standard ticket price was $12.
Step-by-step explanation:
Let’s denote 
the normal ticket price, which would total
if she had purchased tickets for that amount.
However, since Holly received a $4 discount on each ticket, her cost for one ticket became
and with 23 tickets, her total cost was
amounting to $184; thus, we conclude
we will solve this equation as follows:
Therefore, the regular price amounted to $12.
