The answer is less than 90 degrees
Step-by-step explanation:
Before you run any statistical test, you must first determine your alpha<span> level, which is also called the “significance level.” By definition, the </span>alpha<span> level is the probability of rejecting the </span>null<span> hypothesis when the </span>null<span> hypothesis is true.</span>
0.4444444444444
is the answer for your question it repeats so your gonna want to put a bar notation.
Answer:
1. y = 5 - 2x
2. b = a - 3
3. x = 5y - 12
4. c = (12+7d)/3
5. y = (24-4x)/3
6. x = (4 - 3y)/2
Step-by-step explanation:
Answer:
Raul's errors are in the application of the distributive property(he applied it wrongly), in not respecting the precedence of operations, and in the multiplication of two terms with the same base(we add the exponent).
Step-by-step explanation:
Distributive property:
The distributive property of multiplication is:
a*(b + c) = a*b + a*c
Precedence of operations:
First multiplication, then addition.
Multiplication of terms with the same base:
The multiplication of h*h = h², which Raul missed.
The correct simplification is given by:
![-[3h + 7h(2-h)] = -[3h + 14h - 7h^2] = -[17h - 7h^2]=7h^2 - 17h](https://tex.z-dn.net/?f=-%5B3h%20%2B%207h%282-h%29%5D%20%3D%20-%5B3h%20%2B%2014h%20-%207h%5E2%5D%20%3D%20-%5B17h%20-%207h%5E2%5D%3D7h%5E2%20-%2017h)
