Which statement is false
A. Every integer is also a rational number
B. No rational number is irrational
C. Every rational number is also an integer
D. Every irrational number is also real
Answer:
C
Step-by-step explanation:
The answer is C because a rational number is a number that doesn't go forever, and an integer is a positive or negative whole number. For example, 3.5 is rational but not an integer. So, the correct answer is C, and I hope it helps!

A scientist is weighing each of 30 fish. She obtains a mean of 30 g and a standard deviation of 2 g. After completing the weighing, she finds that the scale was misaligned and always under reported every weight by 2 g that is, a fish that really weighed 26 g was reported to weigh 24 g. What is the mean and standard deviation after correcting for the error in the scale
Answer:
Correct mean = 32 grams
Correct Standard deviation = observed S.D = 2 grams
Step-by-step explanation:
We are told in the question above :
A scientist is weighing each of 30 fish. She obtains a mean of 30 g and a standard deviation of 2 g. After completing the weighing, she finds that the scale was misaligned and always under reported every weight by 2 g that is
The mean after correcting the error in the scale is :
= observed mean + 2g
= 30g + 2g = 32g
The standard deviation after correcting the error in the scale remains the same as the difference of 2g has no significant effect on the Standard deviation.
This standard deviation = 2g

Find the equation of a line parallel to 2x + 2y=6 that contains the point (3,-5), Write the equation in slope-intercept
Answer:
[tex]y = -x -2[/tex]
Step-by-step explanation:
Slope-Intercept form of the line
Any given line with slope m and y-intercept b can be written as:
y=mx+b
We need to find the equation of a line parallel to
2x + 2y = 6
Dividing by 2:
x + y = 3
Solving for y:
y = -x + 3
Comparing with the slope-intercept form of the line:
m = -1
Parallel lines have the same slope, thus the required line must have a slope m = -1.
Since we have a point through which the line passes, we use the point-slope form:
y - k = m ( x - h )
Where (h,k) is the point.
The required equation of the line is:
y - (-5) = -1 (x - 3)
Operating:
y + 5 = -x + 3
Solving for y:
[tex]\boxed{y = -x -2}[/tex]

Lanie works part-time at Sweet Treats Catering. She earns $13.25 per hour and work 25 hours a
week. She is paid semi-monthly.
a. Calculate her gross pay for 1 paycheck. Show all your math calculations.
Answer:
Semi-monthly gross pay = $662.5
Step-by-step explanation:
Given:
Earning per hour = $13.25
Number of hours per week = 25 hours
Find:
Semi-monthly gross pay
Computation:
Assume two week in semi-month
So,
Total working hour = 2(25)
Total working hour = 50 hours
Semi-monthly gross pay = Total working hour × Earning per hour
Semi-monthly gross pay = 50 × 13.25
Semi-monthly gross pay = $662.5
Which is the completely factored form of 18x4 – 42x3 + 24x2?
3x(3x - 4)(2x - 2)
3x2(3x - 4)(2x - 2)
6x(3x – 4)(x - 1)
6x²(3x - 4)(x - 1)
Answer:
D
Step-by-step explanation:
The completely factored form is 6x² (3x - 4) (x - 1).
Option D is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
18[tex]x^4[/tex]– 42x³ + 24x²
Now,
The common factor of 18, 42, and 24 is 6.
And x² is common to all the terms.
So,
6x² (3x²– 7x + 4) _____(1)
Now,
(3x²– 7x + 4)
3x² - (4 + 3)x + 4
3x² - 4x - 3x + 4
x(3x - 4) - 1(3x - 4)
(3x - 4) (x - 1) ______(2)
Now,
From (1) and (2) we get,
6x² (3x - 4) (x - 1)
Thus,
6x² (3x - 4) (x - 1) is the completely factored form.

which number makes the number sentence true? (6+9)+4=4+?
Answer
(6+9)+4=4+15
Step-by-step explanation:
First you would do (6+9) because it's in parenthesis. (6+9)= 15. So now our equation looks like 15+4=4+? Next we will do 15+4=19. 19=4+? is the new equation. Now the final step is to do 19-4=15 which is what we will plug into the equation.

A report revealed that the average no. of months that an employee stays in a factory is 36
months. Assuming that the no. of months of an employee tenure in the factory is normally
distributed with a standard deviation of 6 months, find the probability that a certain employee
will stay
a. More than 30 months
b. Less than 24 months
c. Between 24 to 48 months
Answer:
Step-by-step explanation:
Given the following :
Mean(m) = 36 months
Standard deviation (s) = 6 months
A) probability of staying more than 30 months :
Zscore = ( x - m) / s
x = 30
Zscore = (30 - 36) / 6
Zscore = - 6/6
= - 1
P(Z > - 1) = 1 - p(Z < - 1) ; p(Z < - 1) = 0.1587
1 - p(Z < - 1) = 1 - 0.1587 = 0.8413
2)less than 24 months :
Zscore = ( x - m) / s
x = 24
Zscore = (24 - 36) / 6
Zscore = - 12/6
= - 2
P(Z < - 2) = 0.0228
3.) between 24 to 48 months
For 24 months : from above = 0.0228
48 months :
Zscore = ( x - m) / s
x = 48
Zscore = (48 - 36) / 6
Zscore = 12/6
= 2
P(Z < 2) = 0.9772 ( from z table)
Hence,
0.9772 - 0.0228 = 0.9544
