Refer to the Exhibit Teacher's Salary. Find the probability that a randomly selected teacher receives a salary of $45,000 or more. (Do not round your answer)
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]
What is an equation of the line that passes through the points (4, 3) and (-6, 3)?
Answer:
Step-by-step explanation:
(4,3)(-6,3)
3-3/-6-4
m=0
y=3
Answer:
y=3
Step-by-step explanation:
Something that I notice about this is that the 2 y coordinates are the same
This means that the line isn't increasing nor decreasing, it's constant
if we look at the y=mx+b
we have, so far,
y=0x+b
we just need be
we know that when x=4 y=3 so we have
3=(0)(4)+b
b=3
so the answer is just y=3
The cost of 5 squash and 2 zucchini is $132 Three squash and 1 zucchini cost $0.73. Write a system of
equations
Answer:
s=-130.54
z=392.35
if you were to run a business like this I belive you would be losing alot of money perhaps try and check if your missing a decimal
Step-by-step explanation:
Squash=s
Zucchini=z
5s+2z=132
3s+z=.73
Im not sure why your prices are so different, but I think you may have forgotten a decimal point.
set z by itself using the 2nd equation
z=-3s+.73
substitute the equation into the first one
5s+2(-3s+.73)=132
expand
5s-6s+1.46=132
move the 1.46 to the other side and simplify
-s=130.54
s=-130.54
now put this back into one of the equations to find z
3(-130.54)+z=.73
z=392.35
Determine whether each relation is a function. If so, provide the domain and range.
Answer:
Not a function
Step-by-step explanation:
A relation is considered a function if and only if every input value has exactly one output value.
The relation given does not satisfy the condition of a function. The input value, height = 160 cm, is related to different output values (age).
Therefore, the relation is not a function.

Which of the following best describes a triangle with one right angle and two congruent sides?
A right scalene triangle
B. acute scalene triangle
C. right isosceles triangle
D acute isosceles triangle
Answer:
C
Step-by-step explanation:
A is impossible. You cannot have both a right triangle and in the same triangle have an angle in it that is over 90 (that's the meaning of scalene)
B is sort of true, but only sort of. All scalene triangles have an angle over 90 and 2 acute angles.
C this is the answer to the question. It has 1 right angle and 2 equal sides. The two equal sides make it isosceles and the right angle is given.
D an acute triangle has three angles under 90 that add to 180. Not the right description.
A triangle with one right angle and two congruent sides is described as a "right isosceles triangle." (Option C)
Let's break down the terms:
1. Right Angle: A right angle is an angle that measures exactly 90 degrees.
2. Isosceles Triangle: An isosceles triangle is a triangle with at least two sides of equal length (congruent sides).
3. Right Isosceles Triangle: A right isosceles triangle is a special type of isosceles triangle where one of the angles is a right angle (90 degrees) and the other two angles are equal, each measuring 45 degrees.
In a right isosceles triangle, the two congruent sides are the legs of the right triangle, and the third side (opposite the right angle) is called the hypotenuse.
So, among the given options, the best description for a triangle with one right angle and two congruent sides is a "right isosceles triangle" (Option C).

2/9 of the students in a school are in sixth grade.
a. How many sixth graders are there if the school has
90 students?
b. How many sixth graders are there if the school has
27 students?
c. if the school has x students write an expression for the number of students of sixth graders in terms of x
d. how many students are in the school of 42 of them are in 6th grade
Answer:
a) 20 sixth graders.
b) 6 sixth graders.
c) 2/9x sixth graders.
d) 189 students in the school.
Step-by-step explanation:
a) 2/9 of 90 = 2/9 * 90 = 20 students.
b) 2/9 of 27 = 2/9 * 27 = 6 students.
c) 2/9 of x = 2/9x
d) 42 = 2/9x so solve the equation: x = 189 students.
If we have 90 students in the school then we will have 20 sixth grade students.
a. From the details of the question, we have 2/9 of the students in the school in sixth grade. Hence;
Number of students in sixth grade = 2/9 × 90 = 20 sixth grade students
b. If the school has 27 students, number of sixth graders = 2/9 × 27 = 6 sixth grade students
c. If we have x students in the school, the number of sixth graders = 2/9 × x = 2/9x students
d. If we have 42 students in sixth grade, the number of students in the school is;
2/9 × x = 42
x = 9/2 × 42 = 189 students

Answer:
1. 17.8 cm
2. 32.0 cm
3. 15.9 m
Step-by-step explanation:
1. Determination of the length of the arc.
Radius (r) = 6 cm
Angle at the centre (θ) = 170°
Pi (π) = 3.14
Length of arc (L) = ?
L = θ/360 × 2πr
L = 170/360 × 2 × 3.14 × 6
L = 17/36 × 37.68
L = 17.8 cm
2. Determination of the length of the arc.
Diameter (d) = 13 cm
Angle at the centre (θ) = 282°
Pi (π) = 3.14
Length of arc (L) = ?
Next, we shall determine the radius. This can be obtained as follow:
Diameter (d) = 13 cm
Radius (r) =?
r = d/2
r = 13/2
r = 6.5 cm
Finally, we shall determine the length of the arc. This can be obtained as follow:
Radius (r) = 6.5 cm
Angle at the centre (θ) = 282°
Pi (π) = 3.14
Length of arc (L) = ?
L = θ/360 × 2πr
L = 282/360 × 2 × 3.14 × 6.5
L = 282/360 × 40.82
L = 32.0 cm
3. Determination of the length of the arc.
Radius (r) = 11 m
Angle at the centre (θ) = 83°
Pi (π) = 3.14
Length of arc (L) = ?
L = θ/360 × 2πr
L = 83/360 × 2 × 3.14 × 11
L = 83/360 × 69.08
L = 15.9 m
Which graph represents the solution 2x - 5y <3
Answer:
There is no picture... But here is a representation of the inequality on a graph
The graph 2x - 5y < 3 cut the x-axis at the point (3,0) and the y-axis at the point (0,-0.6).
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.
Given inequality is 2x - 5y <3. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
When the inequality 2x - 5y < 3 is plotted on the graph it covers the region which is less than the line 2x - 5y < 3. The graph cut the x-axis at the point (3,0) and the y-axis at the point (0,-0.6).
