Consider the following argument. If there are as many rational numbers as there are irrational numbers, then the set of all irrational numbers is infinite.
The set of all irrational numbers is infinite. ∴
There are as many rational numbers as there are irrational numbers. Let p = "there are as many rational numbers as there are irrational numbers," and let q = "the set of all irrational numbers is infinite."
Is the argument valid or invalid?
Choose the answer that shows the symbolic form of the argument and justifies your conclusion.
a. form: q ∧ p valid, specialization p ∴ q
b. form: p → q invalid, converse error q ∴ p
c. form: q ∧ p invalid, converse error p ∴ q
d. form: p ∨ q invalid, inverse error q ∴ p
e. form: q → p valid, generalization p ∴ q
Answers
Answer:
b. form: p → q invalid, converse error q ∴ p
Step-by-step explanation:
Let
p = "there are as many rational numbers as there are irrational numbers,"
let
q = "the set of all irrational numbers is infinite."
We can write the above argument as:
If there are as many rational numbers as there are irrational numbers, then the set of all irrational numbers is infinite
p → q
The set of all irrational numbers is infinite
q
There are as many rational numbers as there are irrational numbers
p
So collectively it can be written as:
p → q
q
∴p
So it looks like
if p then q
q
therefore p
This is a fallacious argument. This means the conclusion can be false even when the premises are true. This type of argument is invalid.
Suppose we know that “If there are as many rational numbers as there are irrational numbers, then the set of all irrational numbers is infinite” is a true conditional statement. We also know that "the set of all irrational numbers is infinite" is true. This is not enough to say that "there are as many rational numbers as there are irrational numbers," is true. The reason for this is that there is nothing logically about “If p then q” and “q” that means p must follow. So this is a converse error and since converse error is an invalid method of inference rule so this argument is invalid.
Let us prove this argument is invalid with a truth table:
p q p → q q p
T T T T T
T F F F T
F T T T F
F F T F F
Since we know that the premises are:
p → q and q
and the conclusion is p
and an argument is valid if and only if all of its premises are true, then the conclusion is true. We should check that whenever both p → q and q are true then p is true but the third row fails. Thus this is an invalid argument.

Answers
Answer :
Part 17: The value of x is 5.
Part 18: The value of x is 2°.
Step-by-step explanation :
Part 17:
Given:
Length SR = 2x - 9
Length RQ = x + 6
Length SQ = 12
Now we have to determine the value of x.
Length SQ = Length SR + Length RQ
12 = (2x - 9) + (x + 6)
12 = 2x - 9 + x + 6
12 = 3x - 3
3x = 15
x = 5
The value of x is 5.
Part 18:
Given:
∠MLK = 81x - 2
∠HLK = 54x + 2
∠MLH = 50°
Now we have to determine the value of x.
∠MLK = ∠HLK + ∠MLH
81x - 2 = 54x + 2 + 50°
81x - 2 - 54x - 2 = 50°
27x - 4 = 50°
27x = 54°
x = 2°
The value of x is 2°

Forty percent of seeds from maize (modern-day corn) ears carry single spikelets, and the other 60% carry paired spikelets. A seed with single spikelets will produce an ear with single spikelets 29% of the time, whereas a seed with paired spikelets will produce an ear with single spikelets 26% of the time. Consider randomly selecting ten seeds.
a. What is the probability that exactly five of these seeds carry a single spikelet and produce an ear with a single spikelet?
b. What is the probability that exactly five of the ears produced by these seeds have single spikelets? What is the probability that at most five ears have single spikelets?
Answers
Answer:
a)P ( A∩S) = 0.116
b) P (x= 5) =0.272
c) P (at most 5) = 0.950647
Step-by-step explanation:
Let A be an event that the maize (modern-day corn) ears carry single spikelets and B be an event that the maize carry paired spikelets.
Then P (B) = 60% = 0.6
P (A) = 1-P (b) = 0.4
Let S be the event that seed with single spikelets will produce an ear with single spikelets and Q be the event that seed with paired spikelets will produce an ear with single spikelets .
Then
P (S) = 29% = 0.29
P (Q ) = 26% = 0.26
n= 10
We want to find out that exactly 5 single spikelets seeds produce single spikelets .
P ( A∩S) = P(A) *P(S) = 0.4 * 0.29= 0.116
Now we have to find that exactly five of the ears produced by these seeds have single spikelets.
b) P (x= 5) = P(A) *P(S)+ P(B) *P(R)
= 0.4 * 0.29 + 0.6 * 0.26
= 0.116+ 0.156= 0.272
At most five ears have single spikelets.This follows a binomial distribution where n is fixed and also p and q are same.
P ( x= at most 5) = 10C5 ( 0.116)^ 5(0.884)^5 +10C4 ( 0.116)^ 4(0.884)^6+10C3 ( 0.116)^ 3(0.884)^7+10C2 ( 0.116)^ 2(0.884)^8 +10C9 ( 0.116)^ 1(0.884)^9+10C10 ( 0.116)^ 0(0.884)^10
=0.002857+0.018145+ 0.0000234+0.2558+ 0.3824+ 0.29144

Answers
Answer:
a)0.03558
b) 95%
c) 95.6985%
d) 16%
e)15.58%
Step-by-step explanation:
a) Determine the sample standard deviation weight.
Step 1
We find the Mean
Sum of terms/ Number of terms
Number of terms = 50
= 43.73/50
= 0.8746 grams
≈ 0.875 grams
Formula for sample standard deviation = √(x - Mean)²/n - 1
= √0.062042/50 - 1
= √0.001266163265
= 0.03558318796 grams
The empirical rule formula:
1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ
b. Use the Empirical Rule to determine the percentage of M&Ms with weights between 0.803 and 0.947 gram. Hint: = 0.875.
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
μ – 2σ
0.875 - 0.03558 × 2
= 0.80384
μ + 2σ
= 0.875 + 0.03558 × 2
= 0.94616
Hence, 95% of M&Ms with weights between 0.803 and 0.947 gram.
c. Determine the actual percentage of M&Ms that weigh between 0.803 and 0.947 gram, inclusive.
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For x = 0.803
= 0.803 - 0.875/0.03558
= -2.02361
Probability value from Z-Table:
P(x = 0.803) = 0.021505
For x = 0.947
= 0.947 - 0.875/0.03558
= = 2.02361
Probability value from Z-Table:
P(x = 0.947) = 0.97849
Hence,
P(x = 0.947 ) - P(x = 0.803)
= 0.97849 -0.021505
= 0.956985
Converting to percentage
= 0.956985 × 100
= 95.6985%
d. Use the Empirical Rule to determine the percentage of M&Ms with weights more than 0.911 gram.
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
=Mean = 0.875
Standard deviation = 0.03558
μ + σ
0.875 + 0.03558
= 0.91058
≈ 0.911
Hence, 68% of M&Ms with weights more than 0.911 gram.
Therefore, percentage of M&Ms with weights more than 0.911 gram, is on the right hand side(one side of the distribution)
=( 100 - 68)%/2
= 32%/2
= 16%
e. Determine the actual percentage of M&Ms that weigh more than 0.911 gram
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean = 0.875
Standard deviation = 0.03558
x = 0.911
= 0.911 - 0.875/0.03558
= = 1.0118
Probability value from Z-Table:
P(x<0.911) = 0.84418
P(x>0.911) = 1 - P(x<0.911) = 0.15582
Converting to percentage =
0.15582 × 100
= 15.58%
Lauder Company had fixed costs of $282,500, variable costs of $645,000, and actual sales amounted to $1,100,000. If the company has a break-even point at $750,000 in sales revenue.a. determine the margin of safety expressed in dollars
b. determine the margin of safety expressed as a percentage of sales. Enter percentage amount as a whole number.
____%
c. Determine contribution margin ratio
_____%
d. Determine the operating income
$______
Answers
The Operating income is $172,500.
To calculate the margin of safety, contribution margin ratio, and operating income, we need to use the given information.
a. Margin of Safety:
Margin of Safety = Actual Sales - Break-even Sales
Given that the break-even point is at $750,000 in sales revenue and actual sales are $1,100,000, we can calculate the margin of safety:
Margin of Safety = $1,100,000 - $750,000 = $350,000
Therefore, the margin of safety is $350,000.
b. Margin of Safety as a Percentage of Sales:
Margin of Safety Percentage = (Margin of Safety / Actual Sales) * 100
Using the values from the previous calculations:
Margin of Safety Percentage = ($350,000 / $1,100,000) * 100 = 31.82%
Therefore, the margin of safety expressed as a percentage of sales is approximately 31.82%.
c. Contribution Margin Ratio:
Contribution Margin Ratio = (Contribution Margin / Sales) * 100
To calculate the contribution margin, we need to subtract variable costs from sales:
Contribution Margin = Sales - Variable Costs = $1,100,000 - $645,000 = $455,000
Using the values, we can calculate the contribution margin ratio:
Contribution Margin Ratio = ($455,000 / $1,100,000) * 100 = 41.36%
Therefore, the contribution margin ratio is approximately 41.36%.
d. Operating Income:
Operating Income = Sales - Variable Costs - Fixed Costs
Using the values provided:
Operating Income = $1,100,000 - $645,000 - $282,500 = $172,500
Therefore, the operating income is $172,500.
