The value of the greatest integer is equal to 1.
We are given that:
The sum of an integer and 7 times the next consecutive odd integer is 6
Consecutive numbers are the numbers that follow each other continuously in the order from smallest to largest. For example 34 and 35.
Let the first number be x.
Second number = x + 2 ( as we need an odd integer)
ATQ:
x + 7( x + 2) = 6
x + 7 x + 14 = 6
8 x = 6 - 14
8 x = - 8
x = - 1
x + 2 = - 1 + 2
= 1
Therefore, the value of the greatest integer is equal to 1.

we know that, 24E ₊ B = 8.50 and
6E ₊ 2B = 6.50
multiply the first equation by 2 and substract
48E ₊ 2B = 17
6E ₊ 2B = 6.50
after solving both equations we get:
42E = 10.50
we are searching for the value of a dozen eggs, which is 12E
multiply 42E = 10.50 by 12/42 = 6/21
and you get
12E = 10.50 × (6/21) \\ 10.50 = 21/2
12E = (21×6)/(2×21)
12E = 3
so a dozen eggs cost 3 dollars.
Hence we get the cost of a dozen of eggs as $3

How do you solve for x if x/5 = 7/3
We get that, the value of x is 11.67 when the equation is x / 5 = 7 / 3.
An equation is a combination of two expressions connected by an equal sign.
We are given an equation:
x / 5 = 7 / 3
We need to find the value of x.
Multiply both sides by 5
x / 5 × 5 = 7 / 3 × 5
x = 35 / 3
Now, we will divide 35 by 3 and round off the result to two decimal places:
x = 11.67
Therefore, we get that, the value of x is 11.67 when the equation is x / 5 = 7 / 3.

Sheila is baking cookies. The radius of each cookie is 4 centimeters.
What is the circumference of each cookie (use 3.14 for pi and round to
the nearest tenth)?
The circumference of each cookie is 25 cm.
Circumference is usually referred to the outer length of a circle.
If 'r' is the radius of a circle, then the circumference of the circle is given by 2πr, where π = 3.14.
Here, the radius of the each cookie, r = 4 cm
Then the circumference of each cookie = 2πr

If Andrew's batting average is exactly 0.400 going into the series, and that value is based on exactly 2000 career hits out of 5000 previous times at bat, what is the least his average could possibly be when he
goes up to bat the tenth time of the series?
The least Andrew's average could possibly be when he goes up to bat the tenth time of the series is 0.399.
Here, we are given that,
Andrew's batting average = 0.400
Number of career hits for 0.400 batting average = 2000
Previous bat times for 0.400 batting average = 5,000
Now,
For the least possible average, he must have zero career hits in every match he bats.
Before the tenth time of the series, he will bat in 9 times
He must have 0 career hits in these 9 matches he bats in
therefore,
The total number of career hits = 2000
Total number of bat times = 5,000 + 9 = 5,009
Hence,
Average = (Total career hits) ÷ (Total number of times he bats)
= 2000 ÷ 5,009
= 0.399
Thus, the least his average could possibly be when he goes up to bat the tenth time of the series is 0.399.

Eli runs a distance of 3 miles in 2/5 of an hour. Jess runs a distance of 4/5 mile in 1/10 of an hour. Who had the faster speed? show your work.
Jess had the faster speed than Eli.
We have the relation connecting Distance travelled, Time taken to travel and the speed given by,
Distance Travelled = Speed x Time taken
Here, we need to find the speed of Eli and Jess to find out who was faster.
So we use the formula, Speed = Distance travelled / Time taken
Distance travelled by Eli = 3 miles
Time taken by Eli = 2/5 hour
Speed of Eli = Distance / Time taken
= 3/(2/5)
= 15/2 = 7.5 miles per hour
Distance travelled by Jess = 4/5 mile
Time taken by Jess = 1/10 hour
Speed of Jess = Distance / Time taken
= (4/5)/(1/10)
= 8 miles per hour
Comparing the speeds of Eli and Jess, Jess had the faster speed of 8 miles per hour.

Yes the product is equal because even though the numbers may have changed places they did not change the position(numerator to denominator) vice versa.meaning the product of what is in the numerator is equal irrespective of the positions for an e.g in numerator part ion the first terms we have 3*5=15 and in the second scenario we have of course 3*5=15 same applies to the denominators 3*5=5*3There are 31 horses competing in a show, how many ways can the blue,red,and yellow ribbons be awarded
If there are 31 horses competing in a show, then the blue, red, and yellow ribbons can be awarded in 26970 different ways.
As per the question statement, 31 horses are competing in a show.
We are required to calculate the number of ways in which the blue, red and yellow ribbons can be awarded.
To solve this question, first, we need to know a basic rule of horse shows, which is the 1st place or the winner is awarded with a blue ribbon, the second place or the runners-up is awarded with a red ribbon and the third place or the second runners-up is awarded with a yellow ribbon.
That is, in simpler terms, we have to calculate the number of different ways, in which the first, second and third places can be achieved between 31 different horses, each having equal probability of winning.
To solve this question, we just need to know the formula of permutation which goes as [tex][(nPr)=\frac{n!}{(n-r)!} ][/tex], i.e., we are to select an ordered set or "r" from a set of "n".
As per our question, (n = 31) and (r = 3), and using these in the above mentioned formula of permutation, we get
[tex](31C)=\frac{31!}{(31-3)!}=\frac{31!}{28!} =\frac{28!*29*30*31}{28!}=(28*29*30)=26970.[/tex]
That is, the blue, red and yellow ribbons can be awarded in a show with 31 horses as contestants in 26970 different ways.

Answer: 35:30, because 65-30 equals 35 and if you do the empty spaces which there are 35 to the filled spaces which there are 30 it will become your answer of 35:30.
Hope this helps!
The solution is 7 : 6
The ratio of proportion of the empty spaces to the filled spaces is 7 : 6
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
Let the total number of parking spaces be = P
The value of P = 65 spaces
Now , the number of spaces that are filled with cars = 30 spaces
So , the remaining number of spaces = the empty spaces
The remaining number of spaces = total number of parking spaces - number of spaces that are filled with cars
Substituting the values in the equation , we get
The remaining number of spaces = 65 - 30
The remaining number of spaces = 35 spaces are empty
Now , the ratio of empty spaces to filled spaces is given by
Ratio of empty spaces to filled spaces = 35 : 30
On simplifying , we get
Ratio of empty spaces to filled spaces = 7 : 6
Therefore , the proportion is 7 : 6
Hence , The ratio of the empty spaces to the filled spaces is 7 : 6

The probability distribution table is formed clearly in the answer part.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
The probability for all the elements in the sample space can be shown in one table known as distribution table.
Suppose X be the event of choosing a major.
Then, its probability can be given as P(X).
Here, the percent value of a given event is equivalent to their probability.
It can be represented in the form of table as,
X (Major chosen by student) P(X) (Probability)
Math 3% = 0.03
Nursing 22% = 0.22
Psychology 16% = 0.16
Criminal justice 11% = 0.11
Business 48% = 0.48
This table is known as the probability distribution table.

Answer:
x would equal -1.03(1 DP)
"-26x - 12 = 15, solve for x."
Step-by-step explanation:
Start with adding 12 to both sides of the expression. Sides were switched purposely.
[tex]15 + 12 = -26x - 12 + 12[/tex]
Next, simplify your addition process. You do this by using a specific rule.
[tex](-a) = a\:\:\mathrm{if\:a\neq 0}\\-26x = 26x\\26 + (x)\\= 26 + 1\\= 27\\= -26x=27[/tex]
Lastly, we are going to divide both sides by -26(x was cancelled).
[tex]\frac{-26x}{-26}=\frac{27}{-26}[/tex]
Thus,
[tex]x= -1.03[/tex]
