Answer:
A. 42, 120, 162
Step-by-step explanation:
27 x 6 = 162
or
42 + 120 = 162
<span>The sample space of the rolling the cube is 6.
The probability of rolling 2 in a cube is 1. So p(2) is 1/6
Similarly the probability of rolling 5 in cube is 1.
So, p(5) = 1/6
To find p (2 or 5) which is p(2) + p(5)
p(2) + p(5) = 1/6 + 1/6 which is 2/6.
2/6 can be reduced to 1/3.
so right answer is 1/3</span>
Answer:
Step-by-step explanation:
Given triangle is right isosceles since one of the angles is 45°
Let the AC = x, then BC = x and AB is:
- x² + x² = 5²
- 2x²=5²
- x²= 5²/2
- x = 5/√2
- x = 5√2/2
Correct option is D
Hello from MrBillDoesMath!
Answer: 6 u^2 + 4u + 6 = 0 where u = (x-5)^2
Discussion; I think the problem statement should actually be to rewrite <u>this</u> equation:
6 (x-5)^4 + 4 (x-5)^2 + 6 -= 0.
Note the power of "x-5" is 4 in the first term and is 2 in the second term. That is, the power of x-5 in the first terms is double, or the square, of the (x-5) power occurring in the second term. This suggest the substitution u = (x-5)^2. Then the equation can be rewritten as
6 u^2 + 4u + 6 = 0
which is a quadratic in "u".
