Answer:

a slope of 3 is steeper

Step-by-step explanation:

assume if we run by 1 rising by 2 is less than 3. Which in terms of math 3/1 is much steeper than 2/1.

or 3 skipped steps on a staircase is more steeper incline than 2 skipped steps.

In a survey sample of 83 respondents, the mean number of hours worked per week is 39.04, with a standard deviation of 11.51. Cal
soldier1979 [14.2K]

Given that,

Sample size= 83

Mean number= 39.04

Standard deviation= 11.51

We know the critical t-value for  95% confidence interval which is equal to 1.989.

We also know the formula for confidence interval,

CI=( mean number - critical t-value*standard deviation/(sample size)^(1/2), mean number + critical t-value*standard deviation/(sample size)^(1/2))

So, we have

CI= (39.04 - 1.989*11.51/83^(1/2), 39.04 + 1.989*11.51/83^(1/2)

CI= (39.04 - 2.513,39.04 + 2.513)

CI= (36.527,41.553)

Therefore, 95% confidence interval for these data is (36.527,41.553), and this result interpret that the true value for this survey sample lie in the interval (36.527,41.553).

Someone please help will mark brainliest please explain!!!!
Darina [25.2K]

Answer:

This table is a guess-and-check, which means that you input whatever number you think might work in this situation in “city gallons”

Step-by-step explanation:

After you just input that same number to wherever the “6” was in the first row...

E.g., if you put “7” for the next “city gallons”, then you’d put “10 - 7 = 3” in “freeway gal” and so on with ever different number you put in for “city gallons”.

That last part in the way bottom goes the same way! Except you input ”c” instead of a number, which is how you find the actual correct answer.

Hope this helps :)

Answer: some parts of your question is missing below is the missing data

Determine if the given vector field F is conservative or not. F = −6e^y, (−6x + 3z + 9)e^y, 3e^y

answer:

F is conservative

F = -6xe^y + ( 33 + 9 ) e^y + C

Step-by-step explanation:

The Potential functions for F so that F = ∇f.

F = -6xe^y + ( 33 + 9 ) e^y + C
