Answer:
A. The permutations rule takes order into account, whereas the combinations rule does not.
Step-by-step explanation:
Permutation is an orderly form of combination. They both deal with numbers an element can be arranged in different ways.
The main difference is that permutation takes into account the order in which the arrangement takes place while combination doesn’t take that into account.
Combination formula: nCr = n! / r! * (n - r)!
Permutation formula: P(n,r)=n! (n−r)!
Answer:
y=14
Step-by-step explanation:
1.Multiply all terms by the same value to eliminate fraction denominators
2. Simplify it and it gives you 14
The approximate measure of angle T in the given diagram is 79°. The correct option is the first option 79°
<h3>Law of Cosines</h3>
From the question, we are to determine the approximate measure of angle T
From the law of cosines, we can write that
cosT = (s² + u² - t²)/2su
From the diagram,
s = 3.9 cm
u = 2.7 cm
t = 4.3 cm
Thus,
cosT = (3.9² + 2.7² - 4.3²)/2(3.9)(2.7)
cosT = (15.21 + 7.29 - 18.49)/21.06
cosT = 4.01/21.06
cosT = 0.1904
T = cos⁻¹(0.1904)
T = 79.02°
T ≈ 79°
Hence, the approximate measure of angle T in the given diagram is 79°. The correct option is the first option 79°
