Answer:

A)There is not sufficient evidence that the proportion is not 0.30.

Explanation:

When carrying out a statistical test, we always have two types of hypothesis which include null hypothesis and alternative hypothesis. The two hypotheses are opposite of each other, if one rejects one, he/she must accept the other. If the null hypothesis is accepted, it means that there is no statistical significance of the claim. In this case, the null hypothesis is accepted meaning that there is not sufficient evidence that the proportion is not 0.30. Hence, the correct answer is A

A property is sold for $350,000. The buyer has paid $12,000 as earnest money and is obtaining a 70% loan. Based on the informati
Zolol [24]

Answer:

$93,000

Explanation:

Data provided in the question:

selling cost of the property = $350,000

Earnest money paid = $12,000

Percentage of loan obtained = 70%

Now,

The amount of loan obtained = 70% of $350,000

= $245,000

Therefore,

Amount to be paid by self

= selling cost of the property - amount of loan obtained

= $350,000 - $245,000

= $105,000

Thus,

Additional cash the buyer will have to bring to the closing day

= Amount to be paid by self - Earnest money paid

= $105,000 - $12,000

= $93,000

In the study of geomorphology, why do we primarily concentrate on processes rather than on distribution patterns by latitude?
4vir4ik [10]
In the study of geomorphology, processes like weathering and erosion are key to how the rocks will be sculpted by natural forces to produce interesting landforms like buttes and mesas for example. The distribution of geomorphological features like say the Amazon River by latitude is important but the process that shaped the landforms is more important as to how it got its present configuration.

crimeas [40]

<h3>What is the main memory?</h3>

Memory is a computing term for a system or device that stores data for immediate use in a computer, computer hardware, or other digital electronic devices. The terms main memory and primary storage are frequently used interchangeably. The store is a dated word for memory.

The principal internal storage area in a computer, sometimes known as RAM, is the main memory (random access memory). Specs like 4GB, 8GB, 12GB, and 16GB usually invariably relate to the RAM's storage capacity. On the other hand, a computer's disk or solid-state storage capabilities are commonly 128GB or 256GB or greater.

Fixed partitioning refers to the division of the system's main memory into a number of static partitions.
