Answer:
They won't both be rational but that's about it. If one is rational and the other is not then the result is certainly irrational. Subtracting two irrational numbers might produce a rational value but it might also not. Consider: a=1+2–√, b=2–√ and a=3–√, b=2–√.
Step-by-step explanation:
Answer:
Rational number minus irrational number will result in an irrational number respectively : 2 - √3 is an irrational number. And it's consequent results [ Addition ] will also result the same : Aslike : 2 + √3 is also an irrational number. If you dig deep into the question it is similar to the basic odd minus odd or even minus even.

1. You have a 16m by 24m rectangular area in your garden. You want to use it
to construct a swimming pool. The swimming pool will have a surrounding
foot path of 2m. If it costs $3 per square meters to tile the footpath, How
much will it cost to tile the entire footpath?
2m
2m
16 m
24 m

Answer:
Total cost of footpath = 528 m²
Step-by-step explanation:
Width of footpath is 2m.
Thus,
For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²
For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²
Total area = 112 + 64 = 176 m²
cost to tile foot path is $3 per square metres.
Total cost of footpath = 176 × 3
Total cost of footpath = 528 m²

Answer:
u = 150
Step-by-step explanation:
Number of vertices:
10
Find the sum of the interior angles:
180(n - 2)
180(10 - 2)
180(8)
1440
To find u:
u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)
u = 1440 - (1290)
u = 150

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.
The expected value of the winnings from a game will be [tex]2.96[/tex] .
What is Probability ?Probability is the ratio of the number of possible outcomes to the total number of outcomes.
we have,
Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]
Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]
So,
To find the expected value,
Now,
Multiply payout values with its probability and sum these values,
i.e.
Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]
[tex]=0+0.2+0.76+1+1[/tex]
Expected value [tex]=2.96[/tex]
Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .

Students who attend Anytown College pay either in-state or out-of-state tuition, depending on where they reside. The amount, I, spent on in-state tuition and the amount, O, spent on out-of-state tuition for a randomly selected student both follow a Normal distribution.
The mean and standard deviation of the sum S = I + O of tuition for a randomly selected pair of in-state and out-of-state students are μS = $6,348.75 and σS = $1,508.48.
Use the z-table to answer the question.

Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points)
a
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
b
Yes, it is a valid inference because he asked all 26 students in his science class
c
No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class
d
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
Answer: d. No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
Step-by-step explanation: this i because there is a possible bias present in his population

2. The length of a rectangle is 18 centimeters and the width is 6 centimeters. A similar rectangle
has a width of 2 centimeters. What is the length of the second rectangle? (Sketch a picture)
Answer:
6
Step-by-step explanation:
I am unable to sketch a picture for you but I will do my best to help you understand. We know that our length of the first rectangle is 18 cm and the width is 6 cm. At the moment we don't need 18 so we'll put that to the side for now and focus on the width. We understand that in a second similar rectangle, the width is 2 centimeters. in order to find our scale, we must divide the larger width by the smaller width. This means we will divide 6cm by 2 cm. 6/2=3 This means that we also divide 18 by 3 since the similar rectangle is smaller and we are figuring out the missing side. After dividing 18 by 3 we should get an answer of 6. 18/3=6 Which means that our similar rectangle has a length of 6 cm and a width of 2 cm.
I also want to mention that similar rectangles are not the same rectangle however you can think of them as enlargerd/shrunk versions of the original rectangle. I hope this helps.
