Answer:

Pressure = force/area

= 650N/0.12m^2

= 5416.7 to 1 d.p

I got 650N by taking the gravitational field on earth to be 10N/kg.

Weight = mass x gravitational field

= 65 x 10N/kg

= 650

Answer is 5416.7 pascals (Pa)

Or

5308.3 Pa

if gravitational field was taken to be 9.8N/kg

Hope this helps!

Below, the two-way table is given for a class of students. Freshmen Sophomore Juniors Seniors Total Male 4 6 2 2 Female 3 4 6 3
julsineya [31]

The required probability is 3/4.We have to compute the probability

P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.

Determine the total number of juniors.Juniors=2+6=8

<h3>What is the probability?</h3>

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

Since the number of females who are junior is 6, determine the required probability.

P(Female|Junior)=6/8=3/4

Therefore, the required probability is 3/4.
