Answer:

20 ,70

Step-by-step explanation:

Complementary angles sum up to 90

2x + 4x + 30 = 90

     6x  + 30 = 90

Subtract 30 from both sides

6x = 90 - 30

6x = 60

x = 60/6

x = 10

2x = 2*10 = 20

4x +30 = 4*10 +30 = 40 +30 = 70

Answer:

20 and 70

Step-by-step explanation:

2x + 4x + 30 =90

6x=90-30

6x=60

x=60/6x

x=10

so, 2x= 20 and 4x=40

20,70

So AB / PQ = BC / QR

9/3 = 15 / QR

15 / QR = 3

QR = 15/3

= 5.  (answer)

AlekseyPX

Answer:

0.44

Step-by-step explanation:

Given the estimated logistic regression model on risk of having squamous cell carcinoma

-4.84 + 4.6*(SMOKER)

SMOKER = 0 (non-smoker) ; 1 (SMOKER)

What is the predicted probability of a smoker having squamous cell carcinoma?

exp(-4.84 + 4.6*(SMOKER)) / 1 + exp(-4.84 + 4.6*(SMOKER))

SMOKER = 1

exp(-4.84 + 4.6) / 1 + exp(-4.84 + 4.6)

exp^(-0.24) / (1 + exp^(-0.24))

0.7866278 / 1.7866278

= 0.4402863

= 0.44
