What is the conditional of a capital letter is a vowel if and only if it is symmetrical
Answer:
If the capital letter is symmetrical, only then would the letter be a vowel.
Step-by-step explanation:
Note, in logic a conditional statement or sentence refers to a statement that has a hypothesis (assumed condition), with a conclusion (or results).
In other words, the conditional statement is saying that a certain event would occur if the first condition is true.
For example, saying: if today is Monday, only then would tomorrow be Tuesday.

Ramon is making book shelves. He bought a board that is 4/5 meter long. He needs 5 shelves. If he cuts 5 equal-sized pieces from the board, how long is each piece?
Answer:
Each board is (4/25) meters long = 0.16 meters long
Step-by-step explanation:
The board is 4/5 meters long, and he needs to cut 5 equal pieces, so we need to divide 4/5 of a meter in 5 parts.
This mathematically becomes: 4/5 divided by 5 which by the definition of division of rational numbers, is the same as :
4/5 times the reciprocal of 5 = (4/5) * (1/5) = (4/25) = 0.16 meters each board
What is the y-intercept and x-intercept of g(x)=-2x+6
Answer:
see below
Step-by-step explanation:
g(x)=-2x+6
To find the y intercept set x = 0
g(0) = -2(0) +6
g(0) = 6
The y intercept is 6
(0,6)
To find the x intercept set y = 0
0 = -2(x) +6
Subtract 6 from each side
0-6 = -2x+6-6
-6 = -2x
Divide each side by -2
-6/-2 = -2x/-2
3 = x
The x intercept is 3
(3,0)
Answer:
x-int : 3
y-int : 6
Step-by-step explanation:
in order to find x intercept, you set the function equeal to 0
0= -2x + 6
then solve for x
-6 = -2x
3=x
To solve for the y intercept, you plug in 0 for x
y = -2(0) + 6
then solve for y
y = 6

Marshal has the following data:
18

18
t
18
If the mean of the above data is 15, which number could t be?
t has a value of 18.
What is Mean?In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all the values are organized in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.
As per the given data:
Mean of 18, 3, 18, t, 18 is 15
Mean = (Sum of all observations)/(Total number of observation)
Mean = (18 + 3 + 18 + t + 18)/5
15 = (18 + 3 + 18 + t + 18)/5
75 = 57 + t
t = 18
The value of t is 18.

A farmer plants apple trees on a on a 235-acre farm. There are 47,000 apple trees evenly dispersed throughout the farm. How many apple trees are there on each acre of land?
Answer:
There are 200 trees per acre.
Step-by-step explanation:
47000 trees divided by 235 acres gets you 200 trees per acre.
When you go back and check your work, 200 trees per acre times 235 acres equals 47000 trees.

Which graph shows a negative rate of change for the interval 0 to 2 on the x-axis?
Answer:
The last graph
Step-by-step explanation:
Graphs 3 and 4 have negative rates of change.
Options C and D are the correct answer.
We have,
The rate of change for the interval 0 to 2 for each graph can be calculated as:
= (b - a) / (2 - 0)
Where (0, a) and (2, b) are the coordinates on each line.
Now,
Graph 1:
Rate of change.
= (0 - (-3) / (2 - 0)
= 3/2
Graph 2:
Rate of change.
= (-2 - (-3) / (2 - 0)
= (-2 + 3) / 2
= 1/2
Graph 3:
Rate of change.
= (-4 - (-3) / (2 - 0)
= (-4 + 3) / 2
= -1/2
Graph 4:
Rate of change.
= (0.5 - 2) / (2 - 0)
= -1.5 / 2
Thus,
Graphs 3 and 4 have negative rates of change.

Rewrite the expression with a rational exponent as a radical expression.
three to the two thirds power all raised to the one sixth power
Answer:
[tex]\huge\boxed{\sqrt[9]{3}}[/tex]
Step-by-step explanation:
In order to convert the expression [tex](3^{\frac{2}{3}})^{\frac{1}{6}}[/tex] into a radical, we need to simplify it down first.
Using exponent rules, we know that [tex](a^b)^c[/tex] can be simplified to [tex]a^{b\cdot c}[/tex].
Therefore we can say that [tex](3^{\frac{2}{3}})^{\frac{1}{6}}[/tex] is the same as [tex]3^{\frac{2}{3} \cdot \frac{1}{6}}[/tex].
[tex]\frac{2}{3} \cdot \frac{1}{6} = \frac{2}{18} = \frac{1}{9}[/tex]
So we have [tex]3^{\frac{1}{9}}[/tex].
When we have a number to a fraction power, it's the same thing as taking the denominator root of the base to the numerator power.
Basically:
If we have [tex]2^{\frac{3}{4}}[/tex]:
We'll take the denominator root (the denominator is 4) of the base (2):
[tex]\sqrt[4]{2}[/tex]
But inside the radical, we raise the base to the numerator (3) power.
[tex]\sqrt[4]{2^3}[/tex]
Same logic for [tex]3^{\frac{1}{9}}[/tex]
[tex]\sqrt[9]{3^1}[/tex]
[tex]3^1[/tex] is the same as 3.

In 2005, the Federal Aviation Administration (FAA) updated its passenger weight standards to an average of 190 pounds in the summer (195 in the winter). This includes clothing and carry-on baggage. The FAA, however, did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 25 passengers. What is the approximate probability that, in the summer, the total weight of the passengers exceeds 5200 pounds
Answer: 0.0051
Step-by-step explanation:
Given the following :
Average Population weight (m) = 190
Population standard deviation (σ) = 35
Total weight of 25commuters (x) = 5200
Sample mean = 5200 /25 = 108
Sample standard deviation = standard error :
σ / √n = 35/√25 =
35/5 = 7
Zscore = (x - m) / standard error
Zscore = (208 - 190) / 7
Zscore = 18 / 7
= 2.57
P( Z > 2.57) = 1 - p(Z < 2.57)
P(z < 2.57) = 0.9949
1 - p(Z < 2.57) = 1 - 0.9949 = 0.0051
An engineering firm offers testing for electrical products. Currently they are testing a type of compact portable music player. They randomly select a number of the music player and conduct a series of tests and compute an overall score for each unit based upon the results of the testing routine. They determine that the test scores are normally distributed with a mean of 374 and a variance of 1,090. A unit is deemed faulty if it scores below 320. Find the probability of a random unit being faulty. Give your answer as a decimal to 2 decimal places.
Answer:
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
Step-by-step explanation:
Explanation:-
Given mean of the Population 'μ' = 374
Variance of the Population σ² = 1090
Standard deviation of the Population 'σ ' = √1090 = 33.01
Given 'X' be a random variable in normal distribution
[tex]Z = \frac{x -mean}{S.D} = \frac{320-374}{33.01} = -1.636[/tex]
Z = - 1.64
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = P( Z < - 1.64 )
= 1- p(Z > 1.64)
= 1 - ( 0.5 + A(1.64)
= 0.5 - 0.4495
= 0.0505
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505

The inventory policy of a retail company is to hold only the highest sales volume items in its distribution center and to ship the remaining lower sales volume items direct from the respective manufacturers to its stores. This policy is intended to reduce transportation costs. Total annual sales of the company are $1 billion. It is known that half of this amount is accounted for by only 15% of the items. In addition, it is assumed that equation (8.1) in the text can be used to model the Pareto cumulative distribution. (a) If the company wants to stock the top selling 35% of the items in the distribution center, what is the expected value of these items in terms of annual sales? (b) On the other hand, if the company wants to stock only those items accounting for the top 75% of annual sales, what proportion of the items corresponds to this sales volume?
Answer:
a. 75.3% is the expected percentage and this value corresponds to 753 million dollars
b. 34.62% of items corresponds to 75% of this sales volume
Step-by-step explanation:
a. A =x(1-y)/(y-x)
X = 0.15, y = 0.50
A = 0.15(1-0.50)/(0.50-0.15)
= 0.15(0.5)/0.35
A = 0.2143
we have
x = 0.35
y = 0.35(1+0.2143)/(0.2143+0.35)
y = 0.425005/0.5643
y = 0.7531
y = 75.3%
75.3% is the expected percentage and this value corresponds to 753 million dollars
b. y = 0.75
find x
y = x(1+A)/(A+x)
x = yA/(1+A-y)
x = 0.75(0.2143)/1+0.2143-0.75)
x = 0.160725/0.4643
x = 0.3462
34.62% of items corresponds to 75% of this sales volume
