The data show the number of viewers for television stars with certain salaries. Find the regression equation, letting salary be the independent (x) variable. Find the best predicted number of viewers for a television star with a salary of $33 million. Is the result close to the actual number of viewers, 3.03.0 million? Use a significance level of 0.05.
Answers
Answer:
y = 5.064 - 0.010x
Here, in this question x = 33
y = 4.734 million views
In this question data is missing and I filled it out and calculated the questions accordingly. Please refer to the attachment for the data calculated.
Step-by-step explanation:
First of all, this question is incomplete. It lacks the data needed to calculate the required things.
So, I figured out the question and I will try my best to solve the question at hand.
I have calculated the some data sheet in excel. Please refer to the attachment for that data.
let a be the salaries
b be the viewers
[tex]S_{aa}[/tex] = ∑[tex]a^{2}[/tex] - [tex]\frac{ Summtion a^{2} }{n}[/tex]
[tex]S_{aa}[/tex] = 7522.8571
[tex]S_{bb}[/tex] = ∑[tex]b^{2}[/tex] - [tex]\frac{ Summtion b^{2} }{n}[/tex]
[tex]S_{bb}[/tex] = 47.1943
[tex]S_{ab}[/tex] = ∑[tex]ab^{}[/tex] - [tex]\frac{ Summtion a x Summation b^{} }{n}[/tex]
[tex]S_{ab}[/tex] = -76.8286
Now the slope of the required regression equation is:
Slope = [tex]S_{ab}[/tex]/[tex]S_{aa}[/tex] = -76.8286/7522.8571 = -0.010
And the intercept of the required regression equation:
intercept = [tex]\frac{1}{n}[/tex] x (∑b - slope x ∑a) = 5.064
So, the regression equation will be:
y = intercept + slope x
y = 5.064 - 0.010x
Here, in this question x = 33
y = 5.064 - 0.010 (33)
y = 4.734 million views

Here's a graph of a linear function. write the equation that describes that function.
Answers
Answer:
y = 1/4x + 5
Step-by-step explanation:
Here, we want to write the equation of the function
Generally we can have the equation of a straight line as;
y = mx + b
m is slope, b is the y-intercept
From the graph we have the y-intercept as 5
To get the slope, we select any two points and apply the slope formula
Let us have the points;
(8,7) and (4,6)
the slope will be;
m = (y2-y1)/(x2-x1) = (6-7)/(4-8) = 1/4
So the equation of the line is;
y = 1/4x + 5

Solve for X-B(5,0.85), for x = 3.
Answers
Answer:
Solve for X-B(5,0.85), for x = 3.*25*
delete my question if it's wrong
The value of the expression is,
X = 0.138
We have to give that,
An expression is,
⇒ X ~ B (5, 0.85)
for, x = 3
Now, simplify the expression for x = 3 as,
X = ⁵C₃ (0.85)³ (1 - 0.85)³⁻¹
X = (5!/3!2!) (0.85)³ (1 - 0.85)²
X = 10 × (0.85)³ (0.15)²
X = 0.138
Hence, The value of the expression is,
X = 0.138

What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Each video gets an average of 1,500,000 views
Video get Views = 3 x 1,500,000
= 4,500,000 Views
Total Views = 90,000,000 Views
Number of months = Total Views/Views per month
Number of months = 90,000,000 / 4,500,000
= 20 Months
Hence, For 20 Months Dagogo need to upload videos to get 90,000,000 views on his channel.

In the year 2010, a person bought a new car for $26000. For each consecutive year after that, the value of the car depreciated by 10%. How much would the car be worth in the year 2014, to the nearest hundred dollars?
Answers
Answer:
$17,100
Step-by-step explanation:
Set up an equation where y is the worth of the car and t is the number of years since 2010:
y = 26000(0.9)^t
Plug in 4 as t, since it is asking about 2014:
y = 26000(0.9)^t
y = 26000(0.9)^4
y = 17058.6
Round to the nearest hundred dollars:
17058.6
= 17,100
So, the car will be worth approximately $17,100

Answer:
10) 15,794
11) 20,306
Step-by-step explanation:
10) Sin(33) = x÷29
Multiply with 29 on both sides.
x = Sin(33) × 29 = 15,794
11) Tan(55) = 29÷x
Multiply with x on both sides.
xTan(55) = 29
Divide with Tan(55) on both sides.
x = 29 ÷ Tan(55) = 20,306
