Answer:
(19229.11 ,20770.89)
Step-by-step explanation:
We are given the following information:
Sample size, n = 17
Sample mean = 20,000 pounds
Sample standard deviation = 1,500 pounds
Confidence level = 95%
Significance level = 5% = 0.05
95% Confidence interval:
Putting the values, we get,
The value of z is zero
Step-by-step explanation:
The slope is the steepness of the line.
The formula for slope is given by:
Here
(x1,y1) = (1,z)
(x2,y2) = (2,8)
So,
The value of z is zero

Cannot see all of the first question but for the paint question: if he’s got 1 1/3 gallons and 3/6 gallons already, 3/6 can be reduced to 1/2 then added to the 1 1/3 to give him a total of 1 3/4 gallons. 4 1/2 - 1 3/4 means he’ll need 2 and 3/4 gallons.
Linear, when you plot the numbers it will be in a line. Remember “(line)ar”
M,t,h,c,s are all consonants. "Mathematics" has 11 letters and 7 of them are consonants and the other 4 are vowels. 100%/11 = 9.091. 9.091 x 4 = 36.36. So, there is a 36.36 % (4/11) chance that you will pick a vowel and a 63.64 % (7/11) chance that you will pick a consonant.
I hope that helps!!!
