I solved this using the comparison method ;)
Answer:
36hr 16min
Step-by-step explanation:
1pool/17hr - 1pool/32hr = 1 pool/xhr
1/17 - 1/32 = 1/x
Use common denomminator of 17*32 = 544
32/544 - 17/544 = 1/x
15/544 = 1/x
x = 544/15
x = 36 4/15 hr
x = 36hr 16min
Sample space: tails/tails,tails/head,head/tails, head/head.
(the slash divides the first toss and the second toss)
P(head,head)=1/4
P(not tail,tail)=1-1/4=3/4
the probability is not the same.
Hello!
The problem has given us a garden that measures 12 meters by 14 meters. She wants to increase the total area by
increasing the length and width by the
same amount. These two phrases (bold) can be used to find the correct equation.
Holly wants to increase the length of the two sides. Therefore, we can
eliminate the following two equations:
255 = (12)(14)
255 = (12 – x)(14 – x)
The first equation does not increase either side, but rather keeps both sides at their original length. The second equation decreases the measure of both sides. Holly has also said that she wants to increase both sides by “the same amount.” Therfore, we can also eliminate the following equation:
255 = (12 +
)(14)
This equation only increases the measure of one side. There is now only one equation remaining:
255 = (12 + x)(14 + x)
This equation increases both sides of the garden by the same amount. Therfore, we can conclude that
the correct equation is 255 = (12 + x)(14 + x).I hope this helps!
Answer:
We need the picture.
Step-by-step explanation:
Unless the data is skewed (which means there is outliers) then you use mean as the most accurate. If you have a skewed graph or outliers then mean would mislead you to believe prices are higher (if you have high outliers) or low (if you have low outliers). Median is typically very accurate. Mode may be inaccurate if you have a lot of prices in a really high or low value.
