Well, the equation would become 5*10 + 4*-5. (because when a number and a variable are right next to each other, that means they are multiplying). Now all you have to do is solve using the Order of Operations.
5*10+4*-5
50+ 4*-5
50-20
30
You are left with 30 as the correct answer. Hope this helped!

Using linear pairs,

115+5x=180\\\\5x=65\\\\x=\boxed{13}

By the exterior angle theorem,

2y=45+5(13)\\\\2y=45+65\\\\2y=110\\\\y=\boxed{55}

A graduate student wanted to estimate the average time spent studying among graduate students at her school. She randomly sample
expeople1 [14]

Answer:

B. The width of the confidence interval would be smaller.

Step-by-step explanation:

By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.

Therefore, the answer is B. The width of the confidence interval would be smaller.
