Answer:

Guess and Conjecture

Step-by-step explanation:

Conjecture is simply an opinion gotten from an incomplete information .Fro example. 10 boys selected from Nigeria were served pizza. None of them ate pizza.

it is a conjecture to conclude that all the males in Nigeria do not eat pizza, because the information is incomplete

Guess is almost similar to conjecture. It is conclusion from incomplete information. It is based on one's personal opinion. Guess can be true or false. it is underprobaility and hence cant be banked upon to explain a proof.

If (x + 5)^2 = 35, what is the approximate positive value of x?0.92
2.65
3.16
5.48

Answers

Answer:

The approximate positive value of x is 0.92.

Step-by-step explanation:

Given,

$(x+5)^2 = 35$

$x+5 = \pm √(35)$

$x = \pm √(35)-5$

Thus,

$x = √(35)-5$ or $x=-√(35)-5$

By taking positive value,

$x = √(35)-5$

$x=5.91607978 - 5 = 0.91607978\approx 0.92$

⇒ First option is correct.

the approximate value of x = 0.92

Which of these choices is the length of the leg of a 45-45-90 triangle with a hypotenuse of 20? Select one:
a. 10
b. 20
c. 102√102
d. 202√

Answers

Answer: The correct choice is 10√2 units.

Step-by-step explanation: We are given to select the correct choice that gives the length of the leg of a 45-45-90 triangle with a hypotenuse of 20.

Since the given triangle is an isosceles right-angled triangle, so let x units be the length of each of the legs.

Using the Pythagoras theorem, we get

$x^2+x^2=20^2\n\n\Rightarrow 2x^2=400\n\n\Rightarrow x^2=(400)/(2)\n\n\Rightarrow x^2=200\n\n\Rightarrow x=\pm√(2*100)\n\n\Rightarrow x=\pm10\sqrt2.$

Since x is the length of the leg of the given triangle, so we get

x = 10√2 units.

Thus, the correct choice is 10√2 units.

the answer would be b.20

If you make an annual salary of $18,920, what is the maximum monthly rent you can afford?$529.76

$441.47

$882.94

$536.22

Answers

If you make an annual salary of $18,920, Find the maximum monthly rent you can afford:
=> 18 920 dollars / 12 months = 1576.67 dollars is your monthly payment.
Base on the given choices, you can afford all prices but practicality wise, 441.47 dollars is the most recommended rentals.

Answer with explanation:

We will use , $(28)/(36)$ rule here, which states that , 28 % of your monthly income should be used for housing finances and 36 % of your total gross income should be used for debt purposes.

Total Annual Salary = $ 18,920

Monthly salary $=(18920)/(12)$

→→28% of 18,920

$=(28)/(100)* (18920)/(12)\n\n=(529760)/(100* 12)=441.4666\n\n=441.47$

Option B: $ 441.47
