Because you know how many he should end up with of each its actually quite simple.
basically it simplifies down to 12x=24 and 8x=24
which means he should buy 2 packs of hot dog rolls and 3 packs of hot dogs

alexira [117]

The <em><u>correct answer</u></em> is:

We can conclude that 68% of the scores were between 55 and 85; 95% of the scores were between 40 and 100; and 99.7% of the scores were between 25 and 100.

Explanation:

The empirical rule tells us that in a normal curve, 68% of data lie within 1 standard deviation of the mean; 95% of data lie within 2 standard deviations of the mean; and 99.7% of data lie within 3 standard deviations of the mean.

The mean is 70 and the standard deviation is 15. This means 1 standard deviation below the mean is 70-15 = 55 and one standard deviation above the mean is 70+15 = 85. 68% of data will fall between these two scores.

2 standard deviations below the mean is 70-15(2) = 40 and two standard deviations above the mean is 70+15(2) = 100. 95% of data will fall between these two scores.

3 standard deviations below the mean is 70-15(3) = 25 and three standard deviations above the mean is 70+15(3) = 115. However, a student cannot score above 100%; this means 99.7% of data fall between 25 and 100.

Sketch and write the equation for each line : y = mx<br> +b
snow_lady [41]

Answer:

equation  y =7/4x+1

slope = 7/4

Step-by-step explanation:

We have two points so we can find the slope

m =(y2-y1)/ (x2-x1)

   = (4--3)/(2--2)

  = (4+3) / (2+2)

   = 7/4

We know the slope and the y intercept

We can write the equation using y = mx+b where m is the slope and b is the y intercept

y= 7/4x +1

We put at dot at (0,1) and then go up 7 and to the right 4 .  We put another dot

Connect the dots and we have our line.

We could also put dots at (-2,-3) and (2,4) and connect the dots.

Is it right
Rasek [7]
F(t) = t2 + 4t − 14

 

y + 14 + 4 = ( t2 + 4t +4)

y + 18 = ( t + 2)^2

 

so the vertex of the parabola is ( -2 , -18)

 

<span>the axis of symmetry is y = -18</span>
