Answer: we can make 15,504 different math tests
Step-by-step explanation:
Ok, we have a bank with 20 questions (Q1, Q2........ , Q20)
and we want to make a test with 15 of those 20 questions.
As the order of the questions does not matter in the thest ( is the same if the order is Q1, Q2, ...., Q15 than if the order is Q15, Q14, ....., Q1 )
So we only want the number of combinations.
When we have N elements and we want to create groups of K elements, the total number of combinations is:
Here N = 20 and K = 15
So we can make 15,504 different math tests
Answer: 4
Step-by-step explanation:
<u>solve for the missing angle</u>
the total degrees a triangle can have is 180 so
use <u>law of sines</u> to solve for x
cross multiply
divide by
type into calculator with (<em>ALPHA Y= </em>for a fraction on TI-84) MAKE SURE IT IS IN DEGREES
You have a triangle and 1/2 of a circle
(1/2)bh + (1/2)3.14r^2. Radius is (1/2)(3.6) because the drawing shows the diameter
of a half-circle so radius is half of that or 1.8
(1/2)(3.6)(4.8) + (1/2)(3.14)(1.8^2)
8.64 + 5.0868
13.7268 rounds to 13.7
The answer is 72 because 2x6=12 and 5x12=60 and together it’s 72
