Answer:

1.47 mm

Step-by-step explanation:

In week 1 there was 2.6 mm

In week 4 there was 4.07

You want to find the difference of week 1 and 4 meaning you have to subtract week 4's value from week 1's to find how much more rain there was in week 4 than week 1

You would do 4.07-2.6

This is equal to 1.47

THEREFORE there was 1.47 mm more rain in week 4 than week 1

Answer:

i) The bottles of iced tea filled in a <em>plant is the Population</em>

<em>ii) The Average of Population μ = 20 is called Parameter</em>

<em>iii) The sample size 'n' = 50</em>

<em>iv) The mean of the sample 'x⁻ = 19.6 ounces</em>

<em></em>

<u>Step-by-step explanation</u>:-

<u><em>Population</em></u>:-

<em>The total number of observations</em> which we are concerned , whether this number be <em>finite</em> or <em>infinite</em> is called<em> Population.</em>

<em>In Given data </em>

The bottles of iced tea filled in a <em>plant is the Population</em>

<u><em>Parameter</em></u><em>:-</em>

<em>The statistical constants of the Population namely mean and variance are usually refereed to as Parameters.</em>

<em>The Average of Population μ = 20 is called Parameter</em>

<u><em>Sample</em></u><em>:-</em>

<em>A sample is a subset of population</em>

<em>given data sample size </em><u><em>n=50 </em></u><em>bottles at random from the days of production</em>

<u><em>Statistics</em></u>

<em>The sample mean x⁻ and variance S² is called statistics</em>

<em>Given data</em>

<em>These bottles contained an average of 19.6 ounces of iced tea </em>

<em> x⁻ = 19.6 ounces</em>

Each shelf holds 5 hermit-crab cages and 3 hermit-crab care booklets. If there are 23 hermit crab cages and 12 booklets to displ
Harrizon [31]

1. Each shelf holds 5 hermit-crab cages. There are 23 hermit crab cages to be displayed. Divide the number of hermit crab cages to be displayed by the number of hermit crab cages that can be displayed on each shelf:

23=5\cdot 4+3.

This means that you need 5 shelves (4 shelves is not enough, because 3 hermit crab cages will be not displayed).

2. Each shelf holds 3 hermit-crab care booklets. There are 12 hermit-crab care booklets to be displayed. Divide the number of hermit-crab care booklets to be displayed by the number of hermit-crab care booklets that can be displayed on each shelf:

12=3\cdot 4.

This means that you need 4 shelves.

Answer: first, you have to divide 23 by 5 and find the quotient and remainder and divide 12 by 3 and find the quotient and remainder. Then you have to determine the number of shelves needed. You need 5 shelves.
