Answer:
m<x= 53
Step-by-step explanation:
m<x = m<y
so...
all you do is 180-128= 53
because m<z = m<y too
and the m<z+128=180
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:____.
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
Let g (2) = 22 – 5 and h (2) = 22 +1.
Find (g+h) (2)
Answer:
23 + 17 = 40 :)
h(t) = -16t2 + 160t + 384 rewrite in factored form
h(t) = -16t^2 + 160t + 384 Rewritten in factored form is 16(−t−2)(t−12).
Which of the following should you do first when solving the equation 2x-7=3x-2(x+8)
Answer:
multiply 3x-2(x+8)
Step-by-step explanation:
PEMDAS
also you must simplify both sides to solve this problem and that's the first step to simplifying this side (the other one is simplified)
Answer:
You should start the question of by distibuting the group 2(x+8)
Step-by-step explanation:
This is the most imoortant step to start off with because of:
GEMDAS
group, exponent, multiply, divide, add and subtract

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 there! :)
[tex]\large\boxed{-8.4}[/tex]
We can calculate the decimal by converting the fraction to an improper fraction, then dividing.
Derive the inpromper fraction by:
[tex]a\frac{b}{c} = \frac{c * a + b}{c}[/tex]
In this instance:
[tex]-8\frac{2}{5} = \frac{-8* 5 -2 }{5} = \frac{-42}{5}[/tex]
Divide:
-42 ÷ 5 = -8.4.

PLEASE HELP QUICK I HAVE NO CLUE
Answer:
51 + 85 = 136
Step-by-step explanation:
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
CHECKING our answer***
51 + 85 = 136
Answer:
51 and 85
Step-by-step explanation:
add the two ratio parts (3 & 5) and divide by total. you get 17. then multiply the parts by 3 and 5 to get the answer

What is the value of x?
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
