Answer: um i don’t know what your asking me?
Step-by-step explanation:
Answer: (2,5)
Step-by-step explanation:
To find the x coordinate of the vertex, you will set x-2=0 and solve for x
x-2=0
+2 +2
x = 2
Now since we know the vertex has an x coordinate of 2 we have to solve for y by plotting in the x value.
y= 1/2(2-2)^2 + 5
y = 0 +5
y =5
(2,5)
The correct way of getting this answer with proof of simplifying the top to the multiplied amount and then subtracts that then simplify to double check
Answer:
95% confidence interval will be narrower.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 50
95% confidence interval for average alcohol content:
a) 90% confidence interval
- If we calculate a 90% confidence interval, then the confidence interval become narrower because we decreased the confidence percentage.
- This would decrease the margin of error.
- Hence, the confidence interval become narrower.
Answer:
1. 25
Step-by-step explanation:
First, you need to place the numbers in ascending order, meaning from smallest to largest.
You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25
Mean (average), just add the numbers up and divide by how many numbers you have
III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer
Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem
Mode, which number appears the most times repeated
