An ordinary (fair) die is a cube with the numbers

Mathematics

A die is a six-face solid and that rolling it twice will give us a sample space of 36 (calculated by multiplying 6 to itself). 

(1) The outcomes that the sum of the two numbers will be greater than 9 are listed below:
                         5 and 5, 5 and 6, 6 and 5, and 6 and 6
There are four and the probability is equal to 4/36 or 1/9.

(2) The outcomes that the sum is an odd number is listed below:
          1 and 2, 1 and 4, 1 and 6, 2 and 1, 2 and 3, 2 and 5, 3 and 2, 3 and 4, 3 and 6, 4 and 1, 4 and 3, 4 and 6, 5 and 2, 5 and 4, 5 and 6, 6 and 1, 6 and 3, 6 and 5
There are 18. Thus, the probability is 18/36 or 1/2.

First question:

When you bisect an angle, you create two new equal angles, both measuring half of the original angle. So, if the original angle was 52°, the two angles will be 52/2=26 degrees each.

Note: the picture is not very clear, and I'm not sure the original angle is 52°. It it's not, just divide by 2 whatever measure the angle is.

Second question:

Focus on triangles RQP and RSP:

  • They are both right, because Q and S are right angles
  • We are given QP=SP
  • They share the side RP

So, they are congruent. This implies that angle SRP is 50° as well, and then

QRS = QRP+SRP = 50°+50°=100°

Write each expression with a single rational exponent. Show each step of your process. Which expressions are equivalent? Justify
Lena [83]

The expression of all the algebra as single rational exponent are; As written below.

<h3>How to Express Exponents?</h3>

1) We want to express ⁴√x³. This can be expressed as;

x^(3/4)

2) We want to express the exponent ¹/x⁻¹. This is expressed as a single rational exponent as; x

3) We want to have the given expression as a single rational exponent. The expression is; ¹⁰√(x⁵ · x⁴ · x²)

We add the exponents to get;

¹⁰√(x¹¹) = x^(¹¹/₁₀)

4) x^(¹/₃) * x^(¹/₃) * x^(¹/₃)

We just add the exponents to get;

x¹ = x
