A set of nine books is arranged in orderly fashion on a Shelf. Each book has 100 pages that is sheets of paper with printing on both sides making 900 pages in all. A work starting on the first page of the book eats through to the last page of the last book how many pages does the worm eat
Answer:
1( first page of volume 1) + 900 (900 book of 100 pages) + 1 (last page of the book)
Find the distance between the two points (-5, -2) and T(-3, 4).

General Formulas and Concepts:
Pre-Algebra

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Coordinates (x, y)Algebra II
Distance Formula: [tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Step-by-step explanation:
Step 1: Define
Point (-5, -2) → x₁ = -5, y₁ = -2
Point (-3, 4) → x₂ = -3, y₂ = 4
Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d
Substitute in points [Distance Formula]: [tex]\displaystyle d = \sqrt{(-3+5)^2+(4+2)^2}[/tex][√Radical] (Parenthesis) Add: [tex]\displaystyle d = \sqrt{(2)^2+(6)^2}[/tex][√Radical] Evaluate exponents: [tex]\displaystyle d = \sqrt{4+36}[/tex][√Radical] Add: [tex]\displaystyle d = \sqrt{40}[/tex][√Radical] Simplify: [tex]\displaystyle d = 2\sqrt{10}[/tex]A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 417 gram setting. It is believed that the machine is underfilling the bags. A 13 bag sample had a mean of 415 grams with a standard deviation of 30. A level of significance of 0.1 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answer:
P value = 0.407
Hence, as P-value (0.407) is greater than 0.1
Fail to reject Null hypothesis
Step-by-step explanation:
Given the data in the question;
sample size n = 13
sample mean x" = 415
standard deviation s = 30
level of significance = 0.1
so;
Null hypothesis H₀ : μ = 417
Alternative hypothesis Hₐ : μ < 417
degree of freedom DF = n - 1 = 13 -1 = 12
Rejection Region { level of significance = 0.1, df = 12 }
critical value of t is - 1.356 as { left tailed test }
Test Statistics;
t = (x" - μ) / [tex]\frac{s}{\sqrt{n} }[/tex]
we substitute
t = (415 - 417) / [tex]\frac{30}{\sqrt{13} }[/tex]
t = -2 / [tex]\frac{30}{\sqrt{13} }[/tex]
t = -0.24
so, from table;
P value = 0.407
Hence, as P-value (0.407) is greater than 0.1
Fail to reject Null hypothesis

write a equation in the form y= mx or y= mx + b to represent the relationship between the independent and dependent qualities?
Answer:
y = 10x
Step-by-step explanation:
Independent variable (x) = time (minutes)
Dependent variable (y) = distance (feet)
The line passes through the point of origin (0, 0), which means it represents a proportional relationship. Therefore, the equation would be in the form of y = mx. Where,
m = slope = y/x
Using any point on the line, say (5, 50),
m = 50/5
m = 10
To write the equation, substitute m = 10 into y = mx
Thus:
y = 10x
2x + y = 2
x - y = 1
