Answer:
[tex]P(x \ge 45000) = 0.77935[/tex]
Step-by-step explanation:
Given [Missing from the question]
Exhibit Teacher's Salary:
[tex]\bar x=50000[/tex]
[tex]s = 6500[/tex]
Required
Calculate [tex]P(x\ge 45000)[/tex]
First, we calculate the z score
[tex]z = \frac{x - \bar x}{s}[/tex]
[tex]z = \frac{45000 - 50000}{6500}[/tex]
[tex]z = \frac{-5000}{6500}[/tex]
[tex]z = -0.77[/tex]
[tex]P(x \ge 45000) = P(z \ge -0.77)[/tex]
[tex]P(x \ge 45000) = 1 - P(z \le -0.77)[/tex]
From the table:
[tex]P(z \le -0.77) = 0.22065[/tex]
So, we have:
[tex]P(x \ge 45000) = 1 - 0.22065[/tex]
[tex]P(x \ge 45000) = 0.77935[/tex]

Each of the following statements is correct in at least one number system. That is, the statement is correct if we assume the numbers are expressed in a base other than 10. It is up to you to find out which number base makes each statement correct. You need to justify your answer by converting the numbers in each operation to base 10 and showing that the statement is correct. For example, 36/6 = 7 is clearly not correct in base 10, but it is correct in base 12 because 3612 = 4210 and 4210/610 = 710.
Thus, 3612/612 = 712 is true.
a) 42/3 = 13
b) 23 + 44 + 14 + 32 = 223
Answer:
(a) Base 7
(b) Base 5
Step-by-step explanation:
(a) 42/3 = 13 testing base 7 we have:
4x7¹ + 2x7° = 28 + 2 = 30
3x7° = 3
1x7¹ + 3x7° = 7 + 3 = 10
30/3 = 10. Therefore, 42/3 = 13 is in base 7.
(b) 23 + 44 + 14 + 32 = 223. Testing base 5 we have:
2x5¹ + 3x5° = 10 + 3 = 13
4x5¹ + 4x5° = 20 + 4 = 24
1x5¹ + 4x5° = 5 + 4 = 9
3x5¹ + 2x5° = 15 + 2 = 17
2x5² + 2x5¹ + 3x5° = 50 + 10 + 3 = 63
13+24+9+17 = 63.
Therefore, it was done in base 5.

What are the coordinates of the point on the directed line segment from (-6, -3) to
(5,8) that partitions the segment into a ratio of 6 to 5?
Given:
A point divides a directed line segment from (-6, -3) to (5,8) into a ratio of 6 to 5.
To find:
The coordinates of that point.
Solution:
Section formula: If point divides a line segment in m:n, then the coordinates of that point are
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
A point divides a directed line segment from (-6, -3) to (5,8) into a ratio of 6 to 5. Using section formula, we get
[tex]Point=\left(\dfrac{6(5)+5(-6)}{6+5},\dfrac{6(8)+5(-3)}{6+5}\right)[/tex]
[tex]Point=\left(\dfrac{30-30}{11},\dfrac{48-15}{11}\right)[/tex]
[tex]Point=\left(\dfrac{0}{11},\dfrac{33}{11}\right)[/tex]
[tex]Point=\left(0,3\right)[/tex]
Therefore, the coordinates of the required point are (0,3).

The length of the base of a right triangle with an area of 24 square meters and a height of 4 meters is 12 meters.
The correct option is C.
What is a right-angled triangle?A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle.
Given:
An area of the right triangle = 24 square meters.
Height = 4 meters.
Then,
An area of the right triangle = 24 square meters.
1/2 x base x height = 24
1/2 x base x 4 = 24
Base = 12 meters.
Therefore, the base is 12 meters.
