The numbers 1 to 13 are written on 13 separate slips of paper and placed into a box. A slip of paper is randomly drawn from the box. Express probabilities as reduced fractions and as decimals rounded to 3 decimal places. 1. a. What is the probability that the slip of paper has an odd number on it? 1. b. What is the probability that the slip of paper has a number less than 4 on it? Theoretical probability can be used to predict the likelihood of an event. If a single, 6-sided die is rolled there are six possible outcomes. That is, after rolling the die, the side facing up will show one of six possibilities: 1, 2, 3, 4, 5, or 6. The theoretical probability that the die would land with a "2" on the side facing up is P = 1/6 = 0.167 because one out of the 6 possibilities is a "2." MGF2106 Project 2B; SP2020 5 2.

Answer: 1a. 0.538
1b. 0.231
Step-by-step explanation:
For Section A.
Given data:
Numbers to be drawn = 1 to 13
Odd numbers = 7
Even numbers = 6
1a. Probability of drawing an odd number
= 7/13
= 0.538
1b. Probability of drawing a number less than 4.
= 3/13
= 0.231
Section B.

Answer:
real: -1, 2; complex: +i, -i1, 3, 4Step-by-step explanation:
1. The graph (red) shows the only real zeros to be -1 and 2. When the corresponding factors are divided from the function, the remaining factor is the quadratic (x^2 +1), which has only complex roots. The quadratic is graphed in green.
The linear factorization is ...
f(x) = (x +1)(x -2)(x -i)(x +i)
The roots are -1, 2, -i, +i.
__
2. The graph (blue) shows the zeros are 1, 3, 4.
You observe that the sum of coefficients is zero, so x=1 is a root. Factoring that out gives the quadratic (x^2 -7x +12), which you recognize factors as
(x -3)(x -4) . . . zeros of 3 and 4

How to solve the problem?Given,
[tex]x=\frac{1}{3}(y^2+2)^{\frac{3}{2}}[/tex]
[tex]\implies (3x)^\frac{2}{3}=y^2+2\\\implies y^2=(3x)^\frac{2}{3}-2[/tex]
[tex]\implies y=\sqrt{(3x)^\frac{2}{3}-2}[/tex]
Let
[tex]y=\sqrt{(3x)^\frac{2}{3}-2}=f(x)[/tex]
Now, the range of y is given 3≤y≤4
hence, the range of x is [tex](\frac{1}{3}(3^2+2)^{\frac{3}{2}}[/tex],[tex]\frac{1}{3}(4^2+2)^{\frac{3}{2}})[/tex]=(12.16,25.46).
So, [tex]S=\int\limits^{25.46}_{12.16} {2\pi f(x)\sqrt{1+f'(x)^2} dx\\\\=[\frac{\pi}{2}(3x)^{\frac{4}{3}}-\pi (3x)^{\frac{2}{3}}]^{25.46}_{12.16}\\=101.63\pi - 6.99 \pi \\= 94.55 \pi[/tex]
is the area of the required surface.
Hence, 94.55π is the area of the required surface.

Answer:
$285.12
Step-by-step explanation:
Start by finding the discount price
$480 * 0.45 = 216
Now subtract
$480 - 216 = 264
Then you will need to find the sales tax
264 * 0.08 = 21.12
now add
21.12 + 264 = 285.12
$264.00
45% off means that the new price of the desk will be 55% of the original price.
$480.00(100-45) = $480.00(55)
Converting the percent to a decimal gives:
$480.00(0.55)

Solve for x in angle bisector please
Answers
Answer:
x = 15
Step-by-step explanation:
Since, BX is the bisector of [tex] \angle BAC[/tex]
[tex]\therefore m\angle ABX = \frac {1}{2} m\angle ABC\\\\
\therefore 24= \frac {1}{2}\times (4x - 12)\\\\
\therefore 24= \frac {1}{2}\times 2(2x - 6)\\\\
\therefore 24= (2x - 6)\\\\
\therefore 24 = 2x - 6 \\ \\
\therefore 24 +6 = 2x\\\\
\therefore 30 = 2x \\\\
\therefore x = \frac{30}{2} \\\\
\therefore x = 15
