Answer:
<em>The width is 4 cm</em>
<em>The length is 12 cm.</em>
Step-by-step explanation:
<u>Area of a rectangle</u>
Given a rectangle of width W and length L, its area is calculated as follows:
The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:
L = 3W
Substituting into the formula of the area:
Simplifying:
Solving:
The width is 4 cm. Find the length:
L=3W=3*4= 12
The length is 12 cm.
The image attached shows the rectangle on the centimeter grid
Answer
x =(24-√816)/2=12-2√ 51 = -2.283
x =(24+√816)/2=12+2√ 51 = 26.283
Step-by-step explanation:
(Same thing)
x =(24-√816)/2=12-2√ 51 = -2.283
x =(24+√816)/2=12+2√ 51 = 26.283
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
