Answer:</h2>
Luke does a work of 308Nm
<h2>
Step-by-step explanation:</h2>
If we have a constant force that acts on a body in the same direction as the displacement , then the work is defined as the product of the force magnitude and the displacement magnitude . In other words:
, which is valid for a constant force in direction of straight-line displacement.
In this problem:
Therefore:
Answer:
There’s no image, but to find the perimeter of the triangle just add up the totals of each side.
Step-by-step explanation:
Answer:
Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
Step-by-step explanation:
Normal with mean 6.88 minutes and
a standard deviation of 0.57 minutes.
Choose a student at random from this group and call his time for the mile Y. Find P(Y<6)
y ≈ normal (μ, σ)
The z score is the value decreased by the mean divided by the standard deviation
Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
Answer:
40 1/2 days
Step-by-step explanation:
Quantity of biscuits the Jones eats daily = 2/3 of a packet
Total packets of biscuits = 27 packets
How long will 27 packets last the family?
= Total packets of biscuits / daily intake of biscuits of the Jones
= 27 ÷ 2/3
= 27 × 3/2
= 81 / 2
= 40 1/2 days
