rusak2 [61]2 years ago
6 0

Answer:

Step-by-step explanation:1

1/2 years which is 1 year and 5 months.

Explanation:

The formula for simple interest is

You can either substitute the given values first and the solve for

T, or you can transpose the formula to have

T as the subject.

T=100xSIPR

T=100 x 637.50

T=100×637.502500×17

T=1.5

As time is always in years, this means it was for

112 years which is 1 year and 5

months

The data show the number of viewers for television stars with certain salaries. Find the regression​ equation, letting salary be
larisa86 [58]

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

S_{aa} = ∑a^{2}  - \frac{ Summtion  a^{2} }{n}

S_{aa} = 7522.8571

S_{bb} = ∑b^{2}  - \frac{ Summtion  b^{2} }{n}

S_{bb} = 47.1943

S_{ab} = ∑ab^{}  - \frac{ Summtion  a x Summation b^{} }{n}

S_{ab} = -76.8286

Now the slope of the required regression equation is:

Slope =  S_{ab}/S_{aa} = -76.8286/7522.8571 = -0.010

And the intercept of the required regression equation:

intercept = \frac{1}{n} 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

A diver started at 4 feet above ground. After diving he ended at 58 feet below the surface
Andrews [41]

Find two positive numbers satisfying the given requirements. the product is 192 and the sum of the first plus three times the se
Zepler [3.9K]
<h3>Given</h3>

Two positive numbers x and y such that xy = 192

<h3>Find</h3>

The values that minimize x + 3y

<h3>Solution</h3>

y = 192/x . . . . . solve for y

f(x) = x + 3y

f(x) = x + 3(192/x) . . . . . the function we want to minimize

We can find the x that minimizes of f(x) by setting the derivative of f(x) to zero.

... f'(x) = 1 - 576/x² = 0

... 576 = x² . . . . . . . . . . . . multiply by x², add 576

... √576 = x = 24 . . . . . . . take the square root

... y = 192/24 = 8 . . . . . . . find the value of y using the above equation for y

The first number is 24.

The second number is 8.
