A leak in a water tank causes the water level to decrease by 3.6×10−2 millimeters each second. About how many millimeters does t

Paladinen [302]

For this case, the first thing you should do is multiply the rate of decrease by time.
We have then:
(3.6 × 10-2) * (1.8 × 104)
= 648 mm
We are going to convert this number into scientific notation:
= 6.48 * 10 ^ 2 mm
Rounding we have:
= 6.5 * 10 ^ 2 mm
Answer:
The water level in the tank decreases in 6.5 * 10 ^ 2 millimeters in 5 hours

Which of the following cannot be a probability?

Damm [24]

(1)

We know that

probability = ( number of favourable outcomes)/( total number of possible outcomes)

and

number of favourable outcomes is always less than or equal to total number of possible outcomes

so, maximum value of probability is 1

and it's minimum value is 0

so, we get

$0\leq p\leq 1$

so, option-D.........Answer
