Two Perpendicular lines intersect at a single point called the"Intersection".

If The Two Lines Are Y=Ax+B And Y=cx+d, Then Their Intersection Has X Coordinate(d-b)/(a-c) And Y Coordinate {A(d-b)/(a-c)+b}

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

OLga [1]

Answer:

probability that his sample will contain at least one damaged apple (P) = 0.7215

Step-by-step explanation:

Given:

Probability of damaged apples (p) = 12% = 0.12

number of samples (n) = 10

Consider,

x- number of apples damaged.

Using Binomial distribution formula:

P(x) = $(nCx) (P)^x (1-p)^(n-x)$

To find the probability that his sample will contain at least one damaged apple:

P(x≥1) = 1 - P(x<1)

= 1 - P(x=0)

= 1 - $10C_0 (0.12)^0 ( 1-0.12)^(10)$

P(x≥1) = 0.7215

Ksju [112]

Answer:

Music Mart offers a better deal, given that the price of the guitar is $ 219 compared to $ 279.20 for Guitar Central.

Step-by-step explanation:

Since Tania is buying a guitar, and Guitar Central has 20% off coupons available, and has the guitar Tania wants for $ 349, while Music Mart has the guitar Tania wants for $ 419, but is offering a $ 200 rebate, to determine which is the better deal the following calculations must be performed:

Guitar Central

100 - 20 = 80

349 x 0.8 = X

279.20 = X

Music mart

419 - 200 = X

219 = X

Therefore, Music Mart offers a better deal, given that the price of the guitar is $ 219 compared to $ 279.20 for Guitar Central.
