Mathematical equation -
20 + 0.50x = ?
X is the placeholder which in this case equals months
But in this case you want to look for form month three to month 18 (which is 15 months) so three months went by so the equation is
$61.50(being the three months already)
(20+(0.50*15))+61.50=?
If you took 143 and divided it by 15 it gives you about 9.
So you woudl have about 9 people at each table
Answer:
The z-score of a teenage with waist size 33 inch is 2
Step-by-step explanation:
Mathematically, the z-score can be calculated using the formula;
z-score = (x- mean)/SD
where mean = 29 inches , SD = 2 inches and x = 33 inch
Plugging these values, we have
z-score = (33-29)/2 = 4/2 = 2
Answer: 6
Step-by-step explanation:
We will set up a proportion to solve. Let x be equal to ?.
Now, we will cross-multiply.
3 * (x + 4) = 5 * x
3x + 12 = 5x
12 = 2x
6 = x
12 inches = 1 foot
Let x=length of 2nd balance beam in feet
by ratio and proportion
1/12 = x/162
multiply noth sides by 162 to isolate x
(1/12)(162) = (x/162)(162)
162/12 = x
13.5 = x
