Answer:
For A) it is possible that the speed the cat is going over the speed limit
For B) The statement is false as if the error is negative, the speed of the car will be less than the speed limit.
Step-by-step explanation:
Data provided in the question:
Maximum error on a car speedometer = 1.6% = 0.016
Maximum Speed limit on the road = 65 miles per hour
Now,
The error will be ± 1.6%
Now,
When the speedometer reads 64 miles per hour
The possible speed of the car can be
64 miles per hour + Error
= 64 + [0.016 × 64]
= 64 + 1.024
= 65.024 miles per hour
or
The speed can be
64 miles per hour - Error
= 64 - [0.016 × 64]
= 64 - 1.024
= 62.976 miles per hour
Hence,
For A) it is possible that the speed the cat is going over the speed limit
For B) The statement is false as if the error is negative, the speed of the car will be less than the speed limit.

The little square box in the corner between the vertical line and the horizontal one is a symbol indicating that angle is a right angle. It has a measure of 90°. The angles designated 1 and 2 together add up to that 90°. When angles sum to the value 90°, they are called "complementary" angles.
Since angles 1 and 2 also share a side and a vertex, they are also "adjacent" angles.
The appropriate choices are ...
- complementary angles
- adjacent angles
___
<h3>2.</h3>
The same lines define the sides of angles 1 and 2, and they share a vertex. However, they are not adjacent. They are ...
___
<h3>3.</h3>
The angles marked 157° and x° together add up to make a line, so they are supplementary (their total is 180°). They also share a vertex and a side, so they are adjacent. The appropriate choices are ...
- supplementary angles
- adjacent angles
___
<h3>4.</h3>
When two angles total 180°, they are <em>supplementary</em>, whether they have any common parts or not. Since 98° + 82° = 180°, ...
- The angles are supplementary

Can I get brainliest?
Step-by-step explanation:
Answer:
Whenever n increases we get std deviation of sample mean decreases.
Step-by-step explanation:
Given that ducation of the self-employed: according to a recent current population reports, the population distribution of number of years of education for self-employed individuals in the united states has a mean of 13.6 and a standard deviation of 3.0.
The central limit theorem says sample mean follows normal for randomly drawn samples of large sizes.
a) Hence X bar follows a normal with mean = 13.6
and std dev = std dev of sample/square root of sample size.
Hence std dev of x bar = 3/sqrt 100 = 0.3
b) when n =400 square root of n becomes double making the std dev of sample mean exactly 1/2
Hence new std dev = 3/sqrt 400 = 0.15
Whenever n increases we get std deviation of sample mean decreases.
