2x -2 = -200
whats the value of x
Answer:
Step-by-step explanation:
2x - 2 = - 200
Bringing like terms on one side
2x = - 200 + 2 = - 198
2x = - 198
x = - 198/2 = - 99
A study was commissioned to find the mean weight of the residents in a certain town. The study examined a random sample of 132 residents and found the mean weight to be 162 pounds with a standard deviation of 35 pounds. At the 95% confidence level, find the margin of error for the mean, rounding to the nearest tenth
Answer: 6.1
We are 95% confident that the true mean weight of the population is within 6.1 pounds of the sample mean 162.
At the 95% confidence interval, the margin of error for the mean is 6.1 pounds
What is margin error?The margin of error is "a statistic expressing the amount of random sampling error in the results of a survey".
According to the question,
Number of random samples (n) = 132 residents
Mean of weight of random samples (x⁻)= 162
Standard deviation of random samples (σ)= 35 pounds
In order to find at the 95% confidence interval, the margin of error for the mean.
Margin error = z (σ/√n)
The critical region 95% confidence interval under normal curve is 1.96.
= 1.96 (35/√132)
=1.96(35/11.48)
=1.96(3.0488)
= 5.9708636 ≈ 6.1 pounds
Hence, at the 95% confidence interval, the margin of error for the mean is 6.1 pounds.

Mia is helping her glee club raise money to fund a field trip. The glee club secided to sell pencils, which come in boxes of 100. Each pencil sells for $25. Write an equation using b for boxes and m for total money made answer
Answer:
m = 2500b
Step-by-step explanation:
As instructed,
let b = number of boxes sold
let m = total money made.
The total money made, is a function of the number of boxes sold.
Let me break this down:
There are 100 pencils in a box;
if they sold only one box, they will get 100 X $25 = $2500;
if they sold two boxes, they will get 200 X $25 = $5000;
if they sold three boxes, they will get 300 X $25 = $7500;
Following the trend, we can deduce that money made, m = (number of boxes sold X 100 ) X $25
representing this using the variables we were given, we have
m = 100b X 25
hence
m = 2500b

According to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of workers walk or bike to work?
Answer: 24%
Step-by-step explanation:
First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.
This is:
= 5/25 + 1/25
= 6/25
Then convert this to a percentage:
= 6/25 * 100
= 24%

The dimensions of a rectangular pool are 26.5 feet by 14 feet. The
depth of the water when full is 5 feet. Each cubic foot contains 7.48
gallons of water. How many gallons of water, to the nearest tenth, are
needed to fill the pool to 80% capacity?
Answer:
29.9 gallons
80% percent of 5 is 4.
So, we multiply 7.48 by 4, which gives us 29.9 gallons.

Answer:
1. 4 2. 2 3. Does not exist 4. Does not exist 5. 3
Step-by-step explanation:
1. This is the limit as x approaches 2 from the left. That means that x "sneaks up" on 2, but from the left (ironically moving right). As x does that, the graph rises, heading for 4 (even though the point is "empty"). The limit is 4. See attached image 1
2. Let x sneak up on 2 from the right (so moving left towards 2). As x does that, the graph falls, heading for the y-value 2. The limit is 2. See image 2.
3. This limit (two-sided) does not exist because the one-sided limits had different values.
4. This limit does not exist, either. The limit as x approaches 0 from the left is 4. The limit as x approaches 0 from the right is 0. These are different, so the two-sided limit is not defined.
5. g(2) = 3, where the solid dot is. It's the value of the function at x=2.

Answer:
Roots = { 2, 5}
Vertex = (3.5, - 2.25)
Step-by-step explanation:
Roots
From the graph
x = {2, 5}
From factoring the equation
(x - 2)(x - 5) = 0
x = {2, 5}
--------------------------
The equation turns at the vertex
From the graph
(3.5, -2.25)
From the equation
X coordinate of vertex
x = -b/2a
x = 7/2 = 3.5
y = (3.5)² - 7(3.5) + 10
y = 12.25 -24.5 + 10
y = -2.25
