The 99% confidence interval for the population mean is from 1,367.80 to 1,432.20. (Round to two decimal places)
To determine the 99% confidence interval estimate for the population mean, we can use the formula:
CI = x ± z * (σ / √n)
where CI represents the confidence interval, x is the sample mean, σ is the population standard deviation, n is the sample size, and z is the critical value corresponding to the desired confidence level.
Given:
x = 1,400
σ = 125
n = 100
First, we need to find the critical value for a 99% confidence level. The z-value corresponding to a 99% confidence level is approximately 2.576.
Next, we can calculate the confidence interval as follows:
CI = 1,400 ± 2.576 * (125 / √100)
CI = 1,400 ± 2.576 * 12.5
CI = 1,400 ± 32.20

Rewrite the equation y – 4x = –9 in slope-intercept form. simple explanation and proof
Answer:
y=4x-9
Step-by-step explanation:
add 4x to both sides to isolate y
Answer:
The slope-intercept form of this equation would be y = 4x - 9.
(For explanation look down below)
Step-by-step explanation:
Slope-intercept form would be an equation that would look like...
y = mx + b
Where m is the slope and b is the intercept. From this form, we can understand that all we need to do is rearange the formula in a way that positive y would be on its left side. And so we get...
y - 4x = - 9
y - 4x + 4x = - 9 + 4x
y = 4x - 9

[tex]\Large\boxed{\tt Answer:~3x=2x+10;~x=10}[/tex]
[tex]\tt Step-by-step~explanation:[/tex]
Since it shows us that both ends of the segment in the middle bisects the sides of the triangle in the middle, we know that the segment in the middle is half of the hypotenuse (4x + 20).
[tex]\tt a)~ 3x =\frac{1}{2} (4x+20)[/tex]
Let's solve the right side of the equation by distributing[tex]\tt 0.5 (4x+20)\\4x*0.5=2x\\20*0.5=10\\\\b)~2x+10;~3x=2x+10[/tex]
Now, we can solve for x by moving the variable x to one side of the equation and everything else on the other side.

Write an solve the inequality. A gym charges a one time sign-up fee of $10.25 and then $5 each time you go. A student can pay up to $135.25. How many times can the student go to the gym?
Answer:
25 visits
Step-by-step explanation:
Given data
One time fee= $10.25
let the number of times visited be x
and the total cost for x visits be y
Hence
y=10.25+5x------------1
for y=135.25
let us find x
135.25= 10.25+5x
135.25-10.25= 5x
125=5x
x= 125/5

HELP ME PLEASE !! Mao changes the incline angle on his treadmill from 0° to 5°. If the walking surface of the treadmill is 5
feet long, how many inches did Mao raise the end of the treadmill from the floor to the nearest tenth of an inch?
Answer:
5.2 inches
Step-by-step explanation:
We can use trigonometry for this. We know that sin = opposite/hypotenuse so opposite = hypotenuse sin. If we want the answer in inches we set the hypotenuse to inches 5 ft = 60 inches. We just use 60 sin 5 degrees to get to our answer.

Answer:
Step-by-step explanation:
The probability of getting one even and one odd is the sum of probability of getting even and of getting odd and even. Since there are 3 even or odd on each die out of six numbers you have
P(EO)(3/6)(3/6)=1/4 and P(OE)=(3/6)(3/6)=1/4 so 1/4+1/4= 1/2
or you can find the probability of getting two odds or two evens and subtract that from 1
P(EE)=(3/6)(3/6)=1/4, P(OO)=(3/6)(3/6)=1/4
P(EO)=1-1/4-1/4=1/2

if m1=2x° and m3=3x° what is m1
Answer:
36
Step-by-step explanation:
Using the angle addition postulate
angle 1+angle 2+angle 3=180
Angle 2 is 90 degrees,
Angle 1 is 2x degrees
Angle 3 is 3x degrees
Plug this into equation
[tex]2x + 90 + 3x = 180[/tex]
[tex]5x + 90 = 180[/tex]
[tex]5x = 90[/tex]
[tex]x = 18[/tex]
Plug 18 into 2x
[tex]2(18) = 36[/tex]

What are the coordinates of the endpoints of segment M'N'? M'(-6, 9) and N'(4, 9) M'(-6, 9) and N'(3, 9) M'(-2, 3) and N'(7, 9) M'(-2, 3) and N'(1, 3)
Answer:
The answer is B. M'(-6,9) and N'(3,9)
Step-by-step explanation:
To find the coordinates of the endpoints of segment M'N' you'll have to use the rule through which it was dilated.
M(-4,6) after the rule it will be (-4*1.5, 6*1.5) = M'(-6,9)
N(2,6) after the rule it will be (2*1.5, 6*15) = N'(3,9)
The answer is B. M'(-6,9) and N'(3,9)
Hope this helps :)
The required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
Here,
The equation for the dilation is given as,
= {1.5x, 1.45y}
Now,
Put coordinates of M and N in the above equation,
Coordinate of M' = (-4×1.5, 6×1.5) = M'(-6,9)
Similarly, the coordinate of N',
Coordinate of N' = (2×1.5, 6×1.5) = N'(3,9)
Thus, the required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.
