Answer:
The mean is 2.75.
The margin of error is 0.62.
Step-by-step explanation:
In this case, we know the 95% confidence interval, and we want to know the mean and the margin of error.
The mean can be calculated as the average between the upper limit and lower limit:
The margin of error is the difference between the upper (or lower limit) and the mean. It equals the product between the z-value and the standard deviation divided by the square of the sample size.
It can also be calculated as half the difference of the limits of the confidence interval.
We only have the limits of the confidence interval to calculate the margin of error:
Answer:
y=-1/2x+2
Step-by-step explanation:
y = mx + p
m=slope = -1/2
p= y-intercept = 2
Answer:
yo ur teacher got u doin deltamath l m ao i did that same exact thing
The answer is just 4,8,2,6,13
since it is g>3 so then it would be 4,8,2,6,13
hope this helps!

have a nice day :D
The discount percent for the given transaction is calculated as; 6.11%
<h3>What is the percentage Discount?</h3>
We are given;
Mark Price; M.P = 4500
Now, formula for discount amount is;
Discount amount = %Discount * M.P
Discount amount = x% * 4500 = 45x
Also;
Selling price is;
S.P = M.P - Discount Amount
S.P = 4500 - 45x
VAT = Vat% * S.P
VAT = (10%*4500) - 45x
VAT = 450 - 45x
S.P with VAT = S.P + VAT Amount = 4500 - 45x + 450 - 45x = 4950 - 90x
Thus;
4950 - 90x = 4400
Solving for x gives;
x = 6.11%

The graph which best represents the new function is a linear function on a coordinate plane as shown in the image below.
<h3>How to determine the graph of the new function?</h3>
First of all, we would determine the slope of the linear function as follows:
Slope, m = ⅔.
Multiplying by -4, the new slope is:
Slope = ⅔ × -4
Slope = -8/3 or 2.7.
For the equation of this line, we have:
y - y₁ = m(x - x₁)
y - 0 = -8/3(x - 3)
y - 0 = -8/3x + 8
y = -8/3x + 8
Decreasing the y-value by 1, we have:
y = -8/3x + 8
y = -8/3x + 8 - 1
y = -8/3x + 7
Therefore, we would have a linear function on a coordinate plane as shown in the image attached below.
