Find the approximate length (in Earth years) of each planet's year.
a. A Venusian year if Venus is 0.72 AU from the sun.
Answers
The approximate length is 0.62 years or 225 days.
A year is the time it takes for a planet, moon, or other celestial body to make one orbit around the Sun. ( when we take our solar system as an example). In the case of other exoplanets, the celestial bodies, moon, and other planets orbit around the main star. The period of the moon's orbit around the earth is related to the moon.
The reference point is very important in determining the exact length of a year. The length is dependent upon the reference point used for the orbital movement.
Jupiter completes a Single orbit once every 4333 days, due to which one Jupiter year is equivalent to 11.86 earth years.

If Amal can maintain that pace, how long will it take him to run 1 mile?
Answers
The time it would take Amal to run 1 mile if he maintains the pace is 12 minutes
From the question, we are to determine how long it would take Amal to run 1 mile
From the given information,
Amal can run 1\8 mile in 1 1\2 minutes.
First, we will calculate Amal's speed
Using the formula,
Speed = Distance/ Time
Then,
Amal's speed = 1/8 ÷ 1 1/2
Amal's speed = 1/8 ÷ 3/2
Amal's speed = 1/8 × 2/3
Amal's speed =1/12 miles/minute
Now, we will determine how long it would take him to run 1 mile
Time = Distance/ Speed
Time = 1 ÷ 1/12
Time = 1 × 12/1
Time = 12 minutes
Hence, the time it would take Amal to run 1 mile if he maintains the pace is 12 minutes
Here is the complete question:

Linear Regression
The table below shows the average price of a movie ticket during certain years.
PLS HELP
Answers
Answer:
a) y = -441.105 + 0.2232x
b) 2043
Step-by-step explanation:
Correlation measures how closely two variables are linked.
If two variables are correlated, you can draw a line of best fit on the scatter plot.
Explanatory (independent) variable is drawn on the x-axis.Response (dependent) variable is drawn on the y-axis.Plot the points from the table where:
x = yeary = average price (in dollars)(See attached graph).
We can see that the points lie close to a straight line. Therefore, a line of best fit with a positive slope can be drawn, since the two variables are positively correlated.
Linear regression is a method for finding the equation of a line of best fit on a scatter plot.
The regression line of y on x:
[tex]y = a + bx[/tex]
where a = y-intercept and b = slope
If b is positive, the variables are positively correlated.If b is negative, the variables are negatively correlated.We cannot find the y-intercept from inspection of the scatter plot (attached) since we would need to extend the x-axis to thousands of years.
Therefore, to find the regression equation, use a graphing calculator:
[tex]y=-441.105+0.2232x[/tex]
To find the approximate year the movie ticket price will reach $15, substitute y = 15 into the equation and solve for x:
[tex]\implies -441.105+0.2232x=15[/tex]
[tex]\implies 0.2232x=456.105[/tex]
[tex]\implies x=2043.481...[/tex]
Therefore, the approximate year the movie ticket price will reach $15 is during 2043.
Note:
For this problem, we have used the line of best fit (regression line) to predict a value of that is outside the range of the original data. When using values outside the range to predict corresponding values, this is called extrapolation. These predictions can be unreliable because there is no evidence that the relationship described by the regression line is true for all values of x. Therefore, caution should be applied in these cases.

If a polynomial f(x) has a remainder of -4 when divided by x-8, what is f(8)?
Answers
The value of f(8) is -4.
What is a polynomial?Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.
For example, 4x + 5x - 1 is a polynomial.
We can consider the polynomial to be:
f(x) = x - 12 so that when we divided by x - 8 we get a remainder of -4.
i.e
(x - 12) / (x-8)
x - 8 ) x - 12 ( 1
x - 8 [ (x - 8) x 1 = x - 8 ]
-4 [ we change the sign of the coefficient ]
[ x - 8 becomes (-x + 8) ]
[ x gets canceled and -12 + 8 = -4 ]
We see that the quotient is 1 and the remainder is -4.
Now,
We can use this polynomial f(x) = x - 12.
f(8) = 8 - 12 = -4
We can also directly say that the value of f(8) is -4 because the remainder is given as -4.
Thus,
The value of f(8) is -4.

The probability that the teacher selected at random will watch television and recommend it to the learners is 8/38
Given details in this question are as follows :
the probability that the teacher watches television and sees the commercial between the hours of 15:00 and 06:00 is 4 /13.
let the probability that the teacher watches television and sees the commercial between the hours of 15:00 and 06:00 be x
if a teacher sees the commercial then the probability that the teacher recommends it to the learners is 26/38.
let the teacher sees the commercial then the probability that the teacher recommends it to the learners is y
Dependent events: Two events are dependent when the outcome of the first event influences the outcome of the second event. The probability of two dependent events is the product of the probability of X and the probability of Y AFTER X occurs.
it is clear that both events are dependent events.
the product of the probability will be our answer
P(x and y ) = probability of x * probability of y

Answers
The minimum of the objective function, f, subject to the constraints is (10.3, 8.3)
Plugging in 5 points, the intersections of the bounds of the 5 constraints, yields the least solution, f = 7x + 4y.
(0,60) provides 240
(6,30) f= 42+120 = 162
(10.3,8.3) = 72.1+ 33.2 = 105.3
(48,2) = 336+ 8 = 344
(60,0) = 420
At the moment when the minimum f is approximately (10.3,8,3)
5x+y = 60 and x+6y = 60 intersect at that point. Multiply the first equation by 6 and take the second equation out to get 30x + 6y = 360.
x + 6y = 60
29x = 300
Rounding to 10.3, x = 300/29 = about 10.345
adjusted to 8.3, y = 60-5x = 60 - 5(10.345) = 60-51.724
