Answer:

A prediction based on the data is reliable, because the means of the samples are close together.

Step-by-step explanation:

Test approved

The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.

What is Mean?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Given three data sets.

All the samples have 10 data points.

Number of data points = 10

Mean of sample 1 = 9.1

Mean of sample 2 = 9.4

Mean of sample 3 = 8.9

We can see that the mean of the three samples is so close to each other.

So the data is reliable.

Hence the option is A.

if $20.00 is for 12.25kg of peas ...what weight of peas can i get for $4.00​

Answers


2.45kg

First you calculate the price per kg as follows:

If it’s $20 for 12.25 kg, the price per kg is $20/12.25=$1.63 per kg


If you have $4, you can figure out what weight you can get by taking $4/the price per kg, so $4/$1.63, which is 2.45 kg.
