Answer:

Hey there!

It's totally fine if you are having trouble with these kinds of questions, especially if you're new to them.

We can simplify the problem to be -2k-4k+5. Treat k as some number, so we have -6k+5.

Let me know if this helps :)

Answer:

d. Approximate the standard normal distribution with the Student's t distribution

(0.2199 ; 0.2327)

Step-by-step explanation:

Given that :

Sample size, n = 31

Sample mean, xbar = 0.2258

Sample standard deviation, s = 0.0188

Confidence interval (C. I) :

xbar ± margin of error

Margin of Error : Tcritical * s/sqrt(n)

Degree of freedom, df = n - 1 = 31 - 1 = 30

Tcritical value :

T0.05/2, 30 = 2.042

Margin of Error = 2.042 * 0.0188/sqrt(31)

Margin of Error = 0.0068949

C. I = 0.2258 ± 0.0068949

Lower boundary : (0.2258 - 0.006895) = 0.2189

Upper boundary : (0.2258 - 0.006895) = 0.2327

(0.2199 ; 0.2327)

You have $110 in your lunch account and plan to spend $2.75 each school day. How many days will it take to spend all of the mone
Westkost [7]

All we have to do here is divide $110 by $2.75

This will give us the amount of days you can buy lunch with $110


110 ÷ 2.75 = 40

Therefore, it will take 40 days to spend all the money in the account


Hope this helps you

Brainliest would be appreciated!
