What is the value of x?

Answers

Answer:

x = 16

Step-by-step explanation:

(x+2) + (7x+2) + (3x) = 180

Add like terms  

7x + x + 3x = 11x

2 + 2 = 4

11x + 4 = 180

Subtract 4

11x + 4 = 180

11x = 176

Divide by 11

11x = 176

x = 16

Find a 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms. The 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms is:____.

Answers

Answer:

hello your question is incomplete attached below is the complete question

answer : ( 184.019 , 206.219 )

Step-by-step explanation:

The 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms can be calculated using this relationship below

y = Bo + B1 ( 200 )  = 195.118621 , sy =

hence a 95% confidence interval = 195.118621 ± 2.306( 4.813492) i.e.  ( 184.019 , 206.219 )

Answer: y = - 0.4 x - 4.5

Step-by-step explanation:

Equation y=mx+b

m is the slope

x is *ANY* x coordinate

y is *ANY* y coordinate

b is y intercept or WHERE the point is on the Y AXIS

Lets look at the given:

Slope (m) is -2/5

Passes through point 15, -9/2

As you can see, the point goes through the Y axis at (-9/2)

Our equation is y = - 0.4 x - 4.5

Hi,

The ratio of two numbers is 3 to 5.

Let x represent the constant of the proportionality

 3x + 5x = 136

    8x = 136 (divide both sides by 8)

x = 17

The numbers are:

3*17 = 51 and

5*17 = 85
