There are 264 anagrams of the word CADERNO that have vowels before consonants.
We have,
To count the number of anagrams of the word CADERNO that have vowels before consonants, we can use the following steps:
Count the number of vowels in the word.
In this case, there are three vowels: A, E, and O.
Count the number of consonants in the word.
In this case, there are four consonants: C, D, R, and N.
Determine the possible arrangements of vowels and consonants that satisfy the condition of having vowels before consonants.
Since there are three vowels and four consonants, there are two possible arrangements that satisfy this condition:
a) Vowel - Consonant - Vowel - Consonant - Vowel - Consonant - Consonant
b) Vowel - Consonant - Vowel - Consonant - Consonant - Vowel - Consonant
Calculate the number of ways to arrange the vowels and consonants in each of the possible arrangements determined in step 3.
We can use permutations to calculate this.
For arrangement a):
There are 3 ways to choose the first vowel (A, E, or O)
There are 4 ways to choose the first consonant (C, D, R, or N)
There are 2 ways to choose the second vowel (whichever is left out of the two remaining vowels)
There are 3 ways to choose the second consonant (whichever is left out of the three remaining consonants)
There is 1 way to choose the third vowel (the remaining vowel)
There is 1 way to choose the fourth consonant (the remaining consonant)
There is 1 way to choose the fifth consonant (the remaining consonant)
The total number of arrangements for this case is: 3 x 4 x 2 x 3 x 1 x 1 x 1 = 72
For arrangement b):
There are 3 ways to choose the first vowel
There are 4 ways to choose the first consonant
There are 2 ways to choose the second vowel
There are 2 ways to choose the second consonant (whichever is left out of the two remaining consonants)
There are 2 ways to choose the third consonant (whichever is left out of the two remaining consonants)
There is 1 way to choose the third vowel
There is 1 way to choose the fourth consonant
The total number of arrangements for this case is: 3 x 4 x 2 x 2 x 2 x 1 x 1 = 192
Add up the total number of arrangements for both cases to get the final answer:
72 + 192 = 264
Therefore,
There are 264 anagrams of the word CADERNO that have vowels before consonants.

Step-by-step explanation:
employees receive a 10% discount their shopping at Tesco stores. calculate the weekly benefit to an employee who on average spend£14 each weekday and £22 on each day at the weekend.
The weekly benefit of the employees is A = £ 11.40
Given data ,
Let's calculate the weekly benefit for an employee who spends an average of £14 each weekday and £22 on each day of the weekend, considering the 10% discount they receive at Tesco stores.
First, we'll calculate the total amount spent on weekdays and weekends separately:
Amount spent on weekdays = £14/day x 5 days/week = £70/week
Amount spent on weekends = £22/day x 2 days/week = £44/week
Next, we'll calculate the total amount spent in a week by adding the amounts spent on weekdays and weekends:
On simplifying the equation , we get
Total amount spent in a week = £70 + £44 = £114
Now, we'll calculate the 10% discount on the total amount spent:
10% of £114 = £11.40
Hence , the weekly benefit to the employee who receives a 10% discount on their shopping at Tesco stores would be £11.40

In order for this series to be convergent,
the limit as k approaches infinity must be less than 1.
In order for this series to have a limit less than 1, our numerator and denominator degree must be equal or the denominator must have the larger degree.
Why
If the numerator has a larger degree, our test would make this divergent, so the limit would be infinity
Since the denominator have 3 binomials, our power for the denominator will be 3, this the numerator having a degree of 3 or less as well.
So one of the answer is 3.

A car is driving away from El Paso with constant velocity. At 1 p.m., it is 145 miles away from El Paso. At 3 p.m., it is 275 miles away from El Paso.
Part A: Write a linear function that describes the distance (in miles) the car is from El Paso in terms of time (in hours after 12:00 p.m.).
The linear function that describes the distance (in miles) is therefore y = 65x + 80
How to solve for the linear functionWe have to find the slope and the intercept in other to get the linear function
The data points are:
(1, 145) and (3, 275).
m = (y2 - y1) / (x2 - x1)
fixing the data points we have
m = (275 - 145) / (3 - 1)
= 130 / 2
= 65
y = mx + b
(1, 145):
145 = 65(1) + b
b = 145 - 65
= 80

Given that the perimeter of an equilateral triangle is 63 inches, find the height/altitude of the triangle.
The height of the triangle is h = 18.18 inches
Given data ,
In an equilateral triangle, all three sides are equal in length.
Let the length of each side be s
Now , the perimeter of the equilateral triangle is given as 63 inches, so we have:
Perimeter of the triangle = 3s = 63 inches
Dividing both sides by 3, we get:
s = 63/3 = 21 inches
Let's now plot an altitude from one of the equilateral triangle's vertex to the side's midway. As a result, two right-angled triangles will be formed, each with the hypotenuse "s" and sides "s/2" and "h"
From the Pythagoras theorem , we get
(h²) + ((s/2)^2) = s²
Substituting the values we found earlier for "s", we get:
(h²) + ((21/2)²) = 21²
Simplifying further, we have:
(h²) + (10.5²) = 21²
(h²) + 110.25 = 441
Subtracting 110.25 from both sides, we get:
h² = 330.75
On taking square roots on both sides , we get
h = √(330.75)
h ≈ 18.18 inches

A florist wants to determine if a new additive would help extend the life of cut flowers longer than the original additive. The florist randomly selects 20 carnations and randomly assigns 10 to the new additive and 10 to the original additive. After three weeks, 6 carnations placed in the new additive still looked healthy and 2 carnations placed in the original additive still looked healthy. The difference in proportions (new – original) for the carnations that still looked healthy after three weeks was 0.4. Assuming there is no difference in the additives, 200 simulated differences in sample proportions are displayed in the dotplot.
Using this dotplot and the difference in proportions from the samples, is there convincing evidence that the new additive was more effective?
A. Yes, because a difference in proportions of 0.4 or more occurred 7 out of 200 times, meaning the difference is statistically significant and the new additive is more effective.
B. Yes, because a difference in proportions of 0.4 or less occurred 193 out of 200 times, meaning the difference is statistically significant and the new additive is more effective.
C. No, because a difference in proportions of 0.4 or more occurred 7 out of 200 times, meaning the difference is not statistically significant and the new additive is not more effective.
D. No, because a difference in proportions of 0.4 or less occurred 193 out of 200 times, meaning the difference is not statistically significant and the new additive is not more effective.
C. No, because a difference in proportions of 0.4 or more occurred 7 out of 200 times, meaning the difference is not statistically significant and the new additive is not more effective.
====================================================
Explanation:
If the new additive was more effective than the old one, then the difference in proportions (new - old) should be fairly large.
Count the dots over the x axis labels of "0.4" through "0.6"
5 dots over "0.4"1 dot over "0.5"1 dot over "0.6"That makes 5+1+1 = 7 dots total.
There are 7 instances where the difference of proportions is 0.4 or larger.
This is out of 200 observations, so 7/200 = 0.035 = 3.5% of the differences have 0.4 or larger.
This is not very significant. The general rule of thumb is to use 5% as the threshold. Some stats textbooks will use 10%. Other times your teacher will specify the significance level. The Greek letter alpha is often used.
Because 3.5% < 5%, we consider the new additive to not be that effective compared to the original additive.

In the above triangle,
1) the sum of side 1 and 2 is: 4x² + 3x + 4
2) the length of side 3 is: 5x³-6x²-12
1) To find the sum of side 1 and side 2, we simply need to add them together.
Side 1 = 3x² - x - 1
Side 2 = x² + 4x + 5
Side 1 + Side 2 = (3x² - x - 1) + (x² + 4x + 5)
= 3x² + x² - x + 4x - 1 + 5
= 4x² + 3x + 4
Therefore, the sum of side 1 and side 2 is = 4x² + 3x + 4
2) We can derive the expression of the thried side by removing the expression in (1) above form the perimeter.
That is;
(5x³-2x² + 3x - 8) - (4x² + 3x + 4)
First we distribute the negative sign
= 5x³-2x² + 3x - 8 + -1 (4x² + 3x + 4)
= 5x³-2x² + 3x - 8 + -1 (4x²) -1( 3x) -1( 4)
= 5x³-2x² + 3x - 8 + -4x² - 3x - 4
