Considering a line of best-fit, the approximate number of hours in 72 days on Saturn is given by 768.
How to find the equation of linear regression using a calculator?To find the equation, we need to insert the points (x,y) in the calculator.
In this problem, the points are:
(266.67, 25), (373.3, 35), (426.67, 40), (586.67, 55).
Using a calculator, the equation is:
y = 0.09375x + 0.00003455.
For 72 days, we have that y = 72, hence the number of hours is x.
y = 0.09375x + 0.00003455.
72 = 0.09375x + 0.00003455.
x = (72 - 0.00003455)/0.09375
x = 768 hours.

In the equation 3y = 21, what is the next step in the equation solving sequence
Answer:
divide both sides by 3
Step-by-step explanation:
Solving the equation means to have y alone on the left side equaling a number.
Since the variable y is being multiplied by 3, the next step is to do the opposite operation to "multiplying by 3" which is "dividing by 3." Since the rule in algebra is that you must do the same operation to both sides of an equation, the next step is:
divide both sides by 3
in a club there are 7 women and 5 men. A committee of 3 women and 2 men is to be chosen. How many different possibilities are there?
The method for calculating how many arrangements are feasible when only a few items are chosen from a collection of items that are unique is as follows:
[tex]^nC_k=\frac{n!}{k!(n-k)!}[/tex]
Where:
n – the sum of all the elements of a set
k – the number of selected objects (the order of the object may change)
! – factorial
For instance, 3!=1×2×3
So, according to the problem, there are [tex]^7C_3[/tex] possible groups of 3 women out of 7 women. And [tex]^5C_2[/tex] possible groups of 2 men out of 5 men.
Combining we get that there are [tex]^7C_3 ~^5C2[/tex] groups of 3 women and 2 men out of 7 women and 5 men.
Therefore, there are [tex]^7C_3 ~^5C2=\frac{7!}{3!4!}\frac{5!}{2!3!}= 350[/tex] possibilities.

Answer: 98.5
Step-by-step explanation:
There were 942 people in total, 928 of which recognized Exxon.
So, the probability is 928/942, which is about 98.5%
The probability of random consumers knowing of exon will be 98.5%.
What is probability?Probability helps us to know the chances of an event occurring.
[tex]P =\dfrac{Desired \ Outcomes}{Possible outcomes}[/tex]
Given that:-
928 consumers knew exon and 14 did not.The probability will be calculated as:-
Total consumers are 942 out of which 928 knew exon and 14 did not.
P = 928 / 942
P = 0.985
P = 98.5%
Therefore the probability of random consumers knowing of exon will be 98.5%.

(23)_16Arturo worked a 40-hour week at $12 per hour. He then received a raise of $1 per hour and worked a 30-hour week. How much more money did he receive for the first week of work than the second?
Arturo receives $90 more in the first week of work than the second.
What are Working Hours?The time a person spends engaged in compensated work is referred to as working time.
Given,
First Week Working hours = 40 hours, per hour rate = $12
The second-week working hours = 30, per hour rate = $13 (With raise of $1)
Calculation of Wages
First Week wages = Total Weekly Hours × Per Hour rate
= 40 × 12 =$480
Second Week wages = Total Weekly Hours × Per Hour rate
= 30 × 13 =$390
The difference between the First week's wages and the Second week's wages is $90 ($480 - $390).
Thus, Arturo earn $90 more in the first week as compared to the second week.

If you receive a 15% MARKUP on an item costing $60.00, how much money do you pay in total?
Answer:
The total money we have to pay is $69.
Step-by-step explanation:
MARKUP is the amount added to the cost price.
MARKUP formula = 100*profit / cost
Cost of the item = $60.00
put the value in the formula
15 = 100*profit/60
profit = 60 × 15 ÷ 100 = 9
the total money is cost + profit
which is 60 + 9 = $69.
So the total money we have to pay is $69.

solve for x for this problem
Answer:
x = 5 and 6
Step-by-step explanation:
1. Square both sides
x - 5 = (x - 5)(x - 5)
2. Simplify the right side
x - 5 = x^2 - 10x + 25
3. Add 5 to both sides
x = x^2 - 10x + 30
4. Subtract x from both sides
0 = x^2 - 11x + 30
5. Factor
0 = (x-5)(x-6)
x = 5,6
Answer:
x = 5 , x = 6
Step-by-step explanation:
[tex]\sqrt{x-5}[/tex] = x - 5 ( square both sides )
x - 5 = (x - 5)² ← expand using FOIL
x - 5 = x² - 10x + 25 ← subtract x - 5 from both sides
0 = x² - 11x + 30 ← in standard form
0 = (x - 5)(x - 6) ← in factored form
equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x - 6 = 0 ⇒ x = 6
As a check
substitute these values into the equation and if both sides are equal then these values are the solutions.
x = 5
left side = [tex]\sqrt{5-5}[/tex] = [tex]\sqrt{0}[/tex] = 0
right side = 5 - 5 = 0
then x = 5 is a solution
----------------------------------
x = 6
left side = [tex]\sqrt{6-5}[/tex] = [tex]\sqrt{1}[/tex] = 1
right side = 6 - 5 = 1
then x = 6 is a solution

An economy package of cups has 690 green cups. If the green cups are 30% of the total package, how many cups are in the package?
The total number of cups in the package is 2300.
What is Percentage?Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
Here,
Let the total number of cups in the package be x.
Number of green cup = 690
Weightage of green cup in total = 30%
Now,
30% of x = 690
30/100 X x = 690
x = 690 X 100/30
x = 23 X 100
x = 2300
Thus, the total number of cups in the package is 2300.

If the formula for an arithmetic sequence is a subscript n equals 11 plus 6 left parenthesis n minus 1 right parenthesis, then what term in the sequence is the value 107?
An arithmetic sequence is a sequence in which the difference between any two consecutive terms of the sequence is equal. The number of term 107 is 17th.
What is Arithmetic Sequence?
An arithmetic sequence is a sequence in which the difference between any two consecutive terms of the sequence is equal.
a_n = a₁ + (n-1)r

Only function f is increasing, and only function f is negative.
Both functions are increasing, but function g increases at a faster average rate.
The correct option is (C)
What is an increasing function?If the slope of a function is continuously increasing or constant in an interval, the function is known as an increasing function.
let f(x) = [tex]ab^{x} +c[/tex] and x=0 , f(0)= -10
-10=a+c
Now,
f(x) = -33/5*[tex](\frac{1}{11} )^{x}[/tex] - 17/5
f '(x)>0
So, x is increasing function.
g(x) = -18/3*[tex](\frac{1}{11} )^{x}[/tex] +2
g'(x) =-18[tex](\frac{1}{3} )^{x}[/tex]ln(1/3)
ln 1/3<0
So, g'(x)>0
So, g(x) is an increasing function.

Since, g increases at a faster rate.
