Answer:

30 and 60 degrees

Step-by-step explanation:

30 and 60 are complementary angles. 60 is two times the measure of its complementary angle, or 30. 60+30=90.

Complementary angles are angles that add up to 90 degrees.

Angle one = x

Angle two = 2x

2x + x = 90 degrees

Combine like terms.

3x = 90 degrees.

Divide both sides by 3

x = 30

Angle one = x = 30 degrees

Angle two = 2x = 2(30) = 60 degrees.

We're not supposed to help with exams. This isn't an exam, is it?

A(0)=202, A(37)=half that.

$A(t) = 202 (\frac 1 2)^{t/37}$

$A(100) = 202 (\frac 1 2)^{100/37} \approx 31.0$

Last choice.

Given:

mean, u = 0

standard deviation σ = 1

Let's determine the following:

(a) Probability of an outcome that is more than -1.26.

Here, we are to find: P(x > -1.26).

Apply the formula:

$z=\frac{x^{\prime}-u}{\sigma}$

Thus, we have:

$\begin{gathered} P(x>-1.26)=\frac{-1.26-0}{1} \\ \\ P(x>-1.26)=\frac{-1.26}{1}=-1.26 \end{gathered}$

Using the standard normal table, we have:

NORMSDIST(-1.26) = 0.1038

Therefore, the probability of an outcome that is more than -1.26 is 0.1038

(b) Probability of an outcome that

Permutation

Step-by-step explanation:

Permutation is an example of the mathematics in which item are arranged in different way.
For example ABC, ACB, BCA, CBA, CAB, BAC etc.
The order of an arrangement are different in each alphabet.
The product of number also be defined as in the form of n to 1
