You have to do similar calculations you use in algebra. This is how I get the answer;
First I draw out the algebraic formula 55m • X = 8,484 m (meters) 2 (squared). Then I switch the sign from multiplication to division and switch put numbers 55 and 8,484 in different places and change it to your new formula 8,484/(divided) 55 =X. Then you do the math of 8,484 divided by 55 and get an answer of 154.254545. But you can just leave it at the first 2 digits on the right side of the decimal by rounding 4 down and leaving it at an answer of ~~(<This is your answer after being put together with these tips (you always right your final answer using your formula and plugging in the number that we got from dividing 8,484 by 55;
Final answer ( if they wanted it included in a formula); 8,484/55=X let X=~~154.25
Final answer (if they wanted it as one final number as you answer); ~~154.25
*Hope these tips helped you with this mathematical problem :)
Answer:
Step-by-step explanation:
So, to start, we need to label all the values. This is
16, 17, 17, 17, 18, 18 , 18 , 18, 18, 18, 19, 19, and 20.
The Lower Quartile can be found if you know the median. The median in this case is 18. So, the Lower Quartile is just median between the median and the lowest number. So it is the median between 18 and 16. Not average, but the median in the set. In this case it is 17. The Upper Quartile is the same except now it is between the median and highest value, or 18.5. The IQR is found by subtracting the Upper by the Lower, or 18.5-17, or 1.5.
Answer:
<em>12.5w = 419.38</em>
<em>and</em>
<em>15.5w = 419.38</em>
Step-by-step explanation:
find the total cost of all the computer parts.
= 259.99 + 2* 39.95 + 79.49 = $419.38
Shana will save $12.50 per week and Marie will save $15.50
per week
therefore we can create two inequalities
<h2><u> Shana:</u></h2>
12.50 * w = 419.38
<em>12.5w = 419.38</em>
w = 419.38/12.5
w = 33.5504
<h2><u>Marie</u></h2>
15.50*w = 419.38
<em>15.5w = 419.38</em>
w = 419.38/15.5
w =27.0568
