Based on the information given, it should be noted that the probability that the mean value is less will be 0.9863.
<h3>
Solving the probability.</h3>
From the complete information, the mean of the distribution is $403,000 and the standard deviation is $278,000 and the number of houses is 40.
Therefore, the probability that the mean value of the 40 houses is less than 500000 will be:
= P [Z < (500000 - 403000)/43955.66)
= P(Z < 2.2067)
Looking at the z value, this will be 0.9863.

Answer:
yes
Explanation:
The study is an experiment that was conducted between the 1932 and 1972 by the UNPS that is united nations public health services. It was taken up by the center of disease control and prevention. The main aim was to study and observe the diseases when untreated. The initial experiments were made of 6 months.
1. The correct statement that describes a Redox reaction is ( D ) ; A chemical reaction in which electrons are transferred between reactants.
2. The chemical formula that shows the correct subscripts is ( D ) BeF₂
3. The type of reaction that is shown is ; ( C ) decomposition reaction
A Redox reaction ( oxidation-reduction reaction ) involves the exchange/transfer electrons between reactants and the change in the oxidation number of the molecules involved in the reaction changes when an electron is either gained or lost.
Given that the Be has four ( 4 ) electrons and Fluorine has nine ( 9 ) electrons when they combine Fluorine will be left with an excess of electrons therefore the correct chemical formula will be BeF₂
The breaking up of an element into its smaller parts in a chemical reaction is known as a decomposition reaction.
