In a class of 7, there are 2 students who are martial arts masters.
If the teacher chooses 2 students, what is the probability that both of them
are martial arts masters?
Answer:
1/21
Step-by-step explanation:
First, find the possible number of combinations of 2 students picked from 7 since order does not matter:
7 choose 2 = 7 nCr 2 = 7!/2!(7-2)! = 5040/2(120) = 5040/240 = 21
Because there's only one combination where both students are martial arts masters, the probability of selecting 2 students out of 7 given that 2 of the 7 are martial art masters is 1/21.
The next model of a sports car will cost 5.9% more than the current model. The current model costs $36,000.
How much will the price increase in dollars?
What will be the price of the next model?

The general term of a sequence is given by an = 7+3 (n − 1) for n > 1.
Which recursive formula defines this sequence?
Answer:
The fifth term is 8.
Step-by-step explanation:
Give n=5 in the general term
T 5=3(5)-7 = 15–7 =8
Another method
Tn = 3n - 7
T 1 = 3(1)-7 = -4
T 2 = 3(2) -7= -1
d= t 2 - t 1 = -1 -(-4)=3
a = -4 d=3
Tn = a + (n-1)d =
T 5 = a + (5–1)d = a +4 d = -4 +4(3)= 8

If a point is randomly picked inside the square, what is the
probability that it will be inside the circle? Round your answer to
the nearest percent.
Answer:
I would say around 45% chance it is in there while I'm just assuming because the circle is just a little less than half the square
does anyone know how to do this

In the diagram the sphere touches each face of the cube at one point-the center of each face. if each side of the cube is 7cm, what is a reasonable estimate for the unoccupied volume of the cube?
a: 120cm3
b: 140cm3
c: 160cm3
d: 180cm3
Answer:
C
Step-by-step explanation:
Te unoccupied volume (V) of the cube is calculated as
V = volume of cube - volume of sphere
= 7³ - [tex]\frac{4}{3}[/tex] πr³ ( r is the radius and r = 7 ÷ 2 = 3.5 )
= 343 - [tex]\frac{4}{3}[/tex] π × 3,5³
= 343 - [tex]\frac{4}{3}[/tex] π × 42.875
= 343 - 179.59438
= 163.4....
≈ 160 cm³ ( to the nearest 10 cm³ )
