This is a 3rd degree trinomial. It has 3 terms and the highest power of any term is 3. The number of terms tells you that it is a TRInominal. Terms are separated by operators (+, -).

Trinomials are the the polynomials in which the variable has the highest degree of 3<span>
So it is a trinomial"</span>

Simplify.<br> 10u -4u<br> Please help

vovikov84 [41]

Answer:

Step-by-step explanation:

The two terms 10u and 4u are like terms because they both carry the same variable (u) with the same degree (1). So, we can just subtract them as if they were normal numbers 10 - 4:

10u - 4u = 6u

Thus, the answer is 6u.

Hope this helps!

Suppose on a certain planet that a rare substance known as Raritanium can be found in some of the rocks. A raritanium-detector i

aleksandrvk [35]

Answer:

0.967 = 96.7% probability the rock sample actually contains raritanium

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Positive reading

Event B: Contains raritanium

Probability of a positive reading:

98% of 13%(positive when there is raritanium).

0.5% of 100-13 = 87%(false positive, positive when there is no raritanium). So

$P(A) = 0.98*0.13 + 0.005*0.87 = 0.13175$

Positive when there is raritanium:

98% of 13%

$P(A) = 0.98*0.13 = 0.1274$

What is the probability the rock sample actually contains raritanium?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1274}{0.13175} = 0.967$

0.967 = 96.7% probability the rock sample actually contains raritanium

Please help me with 8, 9, and 10 thanks! Show work too

Harrizon [31]

In 8, 9, 10, all the triangles are similar, meaning corresponding sides have the same ratio.

8. hypotenuse / (short side) = 25/x = x/9
x² = 25*9 = 5²×3²
x = √(5²×3²) = 5*3 = 15

9. (long side) / (short side) = x/7 = 9/x
x² = 7*9
x = √(9*7) = 3√7

10. (short side) / (long side) = x/48 = 48/64
x = 48²/64 = 36

The expression for the volume of the cube is 27c¹⁸d⁶.

<h3>What is the volume of the cube?</h3>

The volume of a cube is equal to the product of the length, width, and height of a cube.

The volume of a cube is length × breadth× height

Given that each side of the cube is 3c⁶d² inches.

The volume of a cube is given by the formula as

The volume of a cube = length × breadth× height

Since each side of the cube = 3c⁶d² inches.

Substituting the value of the side,

The volume of a cube = 3c⁶d² × 3c⁶d² × 3c⁶d²

The volume of a cube = (3c⁶d² )³

The volume of a cube = 27c¹⁸d⁶

Therefore, the expression for the volume of the cube is 27c¹⁸d⁶.
