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

Sveta_85 [38]

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 )

attached below is the remaining part the solution

Solve the inequality 17u≥−8, and write the solution in interval notation.

xxTIMURxx [149]

Answer:

u= -8/17 [-8, ∞)

Step-by-step explanation:

solve it like regular equation

17u≥-8

divide 17 on both side

then you get u≥-8/17

so, (u) is any value greater than or equal to -8/17

less than equal means solid dot on number line i think its called also mean ([) meaning it includes this value too. It is a multiplication so it can be any number above -8 or -8 itself. Thus, the interval notation will be [-8, ∞). Infinite is not a fix number so we use this (). hope this helps good luck

7/19, 9/19 11/19

I hope this really helps

basically just add 2 on to the numerator

Show that the statement is true. If GH has endpoints G(−2, 1) and H(4, −1), then the midpoint M of GH lies on the line y = −x +

Alex777 [14]

Midpoint = (x1 + x2) / 2, (y1 + y2)/2
(-2,1)....x1 = -2 and y1 = 1
(4,-1)...x2 = 4 and y2 = -1
time to sub
m = (-2 + 4) / 2 , (1 + (-1) / 2
m = (2/2), (0/2)
m = (1,0) <==

y = -x + 1.....(1,0)...x = 1 and y = 0
0 = -1 + 1
0 = 0 (correct)

so the midpoint M (1,0) lies on the line since its coordinates satisfy the equation <===

Find the equation of the line through ( - 10, - 8) that is perpendicular to the line through (10,6), (5,5).

Furkat [3]

Answer:

y=-5x-58

Step-by-step explanation:

The equation of a line in slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

Perpendicular lines have opposite reciprocal slopes.

Anyways we need to find the slope of the line going through (10,6) and (5,5).

To find the slope, we are going to line up the points vertically and subtract vertically, then put 2nd difference over 1st difference. Like so:

( 10 , 6)

- ( 5 , 5)

------------------

5 1

So the slope of the line through (10,6) and (5,5) is 1/5.

The slope of a line that is perpendicular will be the opposite reciprocal of 1/5.

The opposite reciprocal of 1/5 is -5.

The line we are looking for is y=-5x+b where we need to find the y-intercept b.

y=-5x+b goes through (-10,-8)

So we can use (x,y)=(-10,-8) to find b in y=-5x+b.

y=-5x+b with (x,y)=(-10,-8)

-8=-5(-10)+b

-8=50+b

Subtract 50 on both sides:

-8-50=b

-58=b

So the equation is y=-5x-58
