Answer:
Step-by-step explanation:
3). Naomi walked 4560 m to the nearest 10 m. Peta walked 4600 m to the nearest 100 m.
a). 4555 m ≤ n ≤ 4564 m
4550 m ≤ p ≤ 4649 m
b). If n = 4555 m and p = 4550 m
Then Naomi walked more than Peta
If n = 4555 m and p = 4555 m
Then Both Naomi and Peta walked exactly the same.
If n = 4555 m and p = 4649 m
Then Peta walked further than Naomi.
Therefore, all three statements could be true.
4). (a). x = 120 to nearest 10 → 115 ≤ x ≤ 124
(b). y = 1.24 to 2 decimal places → 1.24
(Already given in 2 decimal places)
(c). z = 0.0124 to 3 significant numbers → 0.0124
The volume of a rectangular prism is given by
area of base × height
The rate at which the tank is being filled is 1 liter per minute which we need to convert
1 liter = 1 dm³
But 1 dm = 10 cm. Hence
1 liter = (10 cm)³ = 1000 cm³
The height h of the water is related to the volume by
volume = area of base × h
In one minute the volume increases by 1 liter or 1000 cm³ and the height increases by
h = volume / area of base = 1000 cm³ / 100 cm² = 10 cm <span>

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.
