Answer:
85%
Step-by-step explanation:
The probability of finding our satisfactory service in the three visits in a row would be the multiplication of the probability of each event.
The event is always the same. 95% of the service will be satisfactory. That is a probability of 95/100
Then the final probability would be:
<em>(95/100) * (95/100) * (95/100) = 0.85
</em>
In other words, the probability that a customer who visits three times will find our service satisfactory is 85%
Answer:
12
Step-by-step explanation: Express your length and width as algebraic expressions:
width = x
length = 3
Use the formula for the perimeter of a rectangle to solve for x:
4 x 3 = 12
width = 12
length = 3
I am pretty sure the answer is
<em>DE = </em>![1 \frac{1}{4}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B1%7D%7B4%7D%20)

Here's how I figured that out. Since AB, the smallest segment is
![\frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20)
of the whole segment, AC, that means all we have to do is use that fraction to find out the length of the DE.
<em>
</em>So, EF, representing the whole segment, is equal to 5. Well, DE will equal
<em> </em>![\frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20)
of EF, so all we have to do is divide 5 by 4 to find our answer and our length for DE. That being said:
<em>
</em>![\frac{5}{4} = 1 \frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B4%7D%20%3D%20%201%20%5Cfrac%7B1%7D%7B4%7D%20)
, which is our answer :)

I'm guessing you're trying to find the better buy right, if so what you have to do for this is put 3/4.45 then you'll find the cost for 1 sandwich, and same for the other one 4/6.72, and the one with the least amount of money spent is your answer.
Answer:
1) ![5r + 2 < s](https://tex.z-dn.net/?f=5r%20%2B%202%20%3C%20s)
2) ![12t + 6s < 960](https://tex.z-dn.net/?f=12t%20%2B%206s%20%3C%20960)
3) ![p - q > 30](https://tex.z-dn.net/?f=p%20-%20q%20%3E%2030)
Step-by-step explanation:
1) Length of a ruler = r
Height of Shiela = s
According to the question ,
5 times the length of a ruler increased by 2 .
⇒ ![5r + 2](https://tex.z-dn.net/?f=5r%20%2B%202)
Also , 5r + 2 is less than height of Shiela.
Hence , the linear inequality is ⇒ ![5r + 2 < s](https://tex.z-dn.net/?f=5r%20%2B%202%20%3C%20s)
2) Let the cost of each t-shirt be 't' & cost of each short be 's'.
⇒ Cost of dozen of t-shirts = 12t and Cost of half a dozen shorts = 6s
According to the question ,
12t & 6s is not greater than Php 960.
Hence the linear inequality is ⇒ ![12t + 6s < 960](https://tex.z-dn.net/?f=12t%20%2B%206s%20%3C%20960)
3) Let the number of Php 100-peso tickets be 'p' and let the number of Php 50-peso tickets be 'q'.
According to the question ,
Difference of p & q is not less than 30
Hence the linear inequality is ⇒![p - q > 30](https://tex.z-dn.net/?f=p%20-%20q%20%3E%2030)
