Answer:
This year, Juanita will have to use $75.
Step-by-step explanation:
Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.
x would equal to 9 due to the fact that u do 21+6 and then u do 27÷3
Answer: 4th sequence is closest to the theoretical probability of drawing a king or queen.
Step-by-step explanation:
Since we have know that there are 4 queens and 4 kings in the regular pack .
Total number of cards = 52
So, probability of getting king or queen is given by
![\frac{4}{52}+\frac{4}{52}=0.15](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B52%7D%2B%5Cfrac%7B4%7D%7B52%7D%3D0.15)
1)5 6 8 2 Q 4 8 3 2 A 2 3 10 J J 4 A 5 3 8
So, probability of getting king or queen is given by
![\frac{1}{20}=0.05](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D%3D0.05)
2)K J 5 8 4 3 6 Q 9 J Q 2 8 Q 9 2 Q A 7 K
So, probability of getting king or queen is given by
![\frac{4}{20}+\frac{2}{20}=\frac{6}{20}=0.3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B20%7D%2B%5Cfrac%7B2%7D%7B20%7D%3D%5Cfrac%7B6%7D%7B20%7D%3D0.3)
3)3 8 3 2 7 4 J A 6 3 2 A A 6 3 8 6 10 5 4
So, probability of getting king or queen is given by
0 as there is no queen as well as king.
4)4 8 6 K J 7 Q 3 A K 2 5 8 9 10 2 4 A 6 7
So, probability of getting king or queen is given by
![\frac{2}{20}+\frac{1}{20}=\frac{3}{20}=0.15](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B20%7D%2B%5Cfrac%7B1%7D%7B20%7D%3D%5Cfrac%7B3%7D%7B20%7D%3D0.15)
Hence, 4th sequence is closest to the theoretical probability of drawing a king or queen.
1. We assume, that the number 71 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>
3. If 71 is 100%, so we can write it down as 71=100%. </span>
<span>
4. We know, that x is 68% of the output value, so we can write it down as x=68%. </span>
5. Now we have two simple equations:
1) 71=100%
2) x=68%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
71/x=100%/68%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 68% of 71
71/x=100/68
<span>(71/x)*x=(100/68)*x - </span>we multiply both sides of the equation by x
<span>71=1.4705882352941*x - </span>we divide both sides of the equation by (1.4705882352941) to get x
<span>71/1.4705882352941=x </span>
<span>48.28=x </span>
x=48.28
<span>now we have: </span>
<span>68% of 71=48.28</span>
