Percent change = (new number - old number)/(old number) * 100
percent change = (54 - 48)/(48) * 100 = 6/48 * 100 = 0.125 * 100 = 12.5%
Answer:

Answer:
Positive co terminal angle = -105°
Negative co terminal angle = 225°
Step-by-step explanation:
We have been given the angle 75° and we have to find one positive and one negative co-terminal angle.
In order to find the co terminal angle, we add and subtract 180° to the given angle.
Therefore, the negative co terminal angle is given by
75 - 180 = -105°
And the positive co terminal angle is given by
75 + 180 = 225°
Answer:
Step-by-step explanation:
Alright, lets get started.
Suppose car was driven x miles in its 4 days trip.
Cost of a car rental is thirty dollar per day.
So, for 4 days, the car rental will be = 
$
For 1 mile, it adds fifteen cents,
So, for x miles, the cost will be = 
$
As per question, total rent is 180 $
Total rent will be = 
Subtracting 120 in both sides
It means car was driven 400 miles. : Answer
Hope it will help :)
Answer:
The larger the number of items in the sample, the more closely the distribution of sample items will follow a bell-shaped curve
Step-by-step explanation:
The question is about the distribution of the sample
The sampling distribution, also called the distribution of the sample mean is the distribution for many samples drawn form population at random for large sizes.
As per central limit theorem, if samples of sufficiently large size to represent the population is drawn from the population, the sample means of all sample will follow a normal distribution and hence bell shaped.
So from the options we say a is incorrect because not always
b is incorrect because there is no mention about the chance.
c is incorrect because when we use sample variance we use t test
Option d is correct.
The larger the number of items in the sample, the more closely the distribution of sample items will follow a bell-shaped curve
