13. 10-14
14.I can't see the whole graph, so you need to do it yourself. Add up everyone's age and divide by the amount of people on the graph. That will give you the average.
Slope-intercept form is <em>y</em><em> = </em><em>mx</em> + <em>b</em>, where <em>m</em> is the slope and <em>b</em> is the <em>y</em>-intercept. To write this in slope-intercept form we must isolate the <em>y</em>:
2x + 3y = 1470
2x + 3y - 2x = 1470 - 2x (subtraction will cancel the positive 2x on the left side of the equation)
3y = -2x + 1470 (since they are not like terms we cannot combine them, we leave them separate)
3y/3 = -2/3x + 1470/3 (cancel the 3 by dividing; EVERYTHING gets divided to keep it equal)
y = -2/3x + 490
The slope of this equation is -2/3 and the <em>y</em>-intercept is 490.
To graph this equation, plot 490 on the <em>y</em>-axis first, since it is the intercept. Then count over to the right 3 and down 2 to find the next point; continue this for all successive points.
In function notation this would be <em>f</em>(<em>x</em>) = -2/3<em>x</em> + 490. This function shows how the profit on wrap specials changes as the number of sandwich specials sold increases. The graph of the function is attached.
The next month, when Sal's profit increased, the function changes because the <em>y</em>-intercept changes. The slope stays the same.
Not with whole numbers, your only options would be
6x4 which would have a perimeter of 20
8x3 p=22
12x2 p=28
24x1 p=50
as for decimals, i don't believe that there would be any but not 100% sure
All the numbers present in cubical dice = 6
- ( 1 , 2 , 3 , 4 , 5 ,6 ) <u>Total Outcomes = 6</u>
<u>Probability = Favorable outcomes / Total number of outcomes </u>
- Probability that 5 will come in first throw :-
<u>Favorable Outcomes = 1 </u>
<u>Favorable Outcomes = 1 Probability = 1/6</u>
- Probability that an odd number will come in second throw :-
<u>Favorable Outcomes = 3</u>
<u>Probability = 3/6 ; 1/2</u>
