damaskus [11]4 years ago
3 0

Answer:

10×4 = 40

10^4 = 10,000

Step-by-step explanation:

10^4 is another way to write 10⁴ = 10·10·10·10 = 10,000.

Essentially, the exponent tells you how many places to the right of the leading digit the decimal point lies (here, the number of zeros in the number).

_____

<em>Comment on the answer choice</em>

The appropriate answer depends on what you mean by your problem statement. Some microscopes magnify 40 times; others magnify 10,000 times, so we cannot tell the appropriate answer using our knowledge of microscopes.

A veterinary technician recorded the weights of 12 puppies. Of these 12 puppies, 3 weighed over 6 pounds. What percentage of the
OLga [1]

The percentage value of puppies weighing over 6 pounds is 25%

What is Percentage?

Percentage is a relative number that represents the hundredth part of any quantity. One percent (symbolised 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.

Solution:

Given that there are 12 puppies in total and 3 of them weighted above 6 pounds

To calculate the percentage we need to divide 3 by 12 and then multiply it by 100

= (3/12) * 100

= 25%

State whether the data described below are discrete or​continuous, and explain why.The heights (in feet) of different buildingsC
vichka [17]

Answer:  

Option D) The data are continuous because the data can take on any value in an interval

Step-by-step explanation:

We are given the following in the question:

Data: The heights (in feet) of different buildings

Discrete and continuous data:

  • Discrete data is the data that cannot take values in decimals and continuous data can take values in decimals.
  • Continuous data can take any value within an interval.
  • Discrete data cannot take all the value within an interval.
  • Discrete data is counted where as continuous data is measured.

Thus, height is a continuous data since it can take any values within an interval and is measured.

Thus, the correct answer is

Option D) The data are continuous because the data can take on any value in an interval

Which one of the following will result in movement along the demand curve for clothing as opposed to a shift in the demand curve
Assoli18 [71]

Answer:

d) Clothing prices decline because manufacturers shift to production in countries with lower wages.

Step-by-step explanation:

Demand is the quantity of goods or services consumers are able and willing and able to buy at a given price and at a particular time.

Movement along the demand curve also known as change in quantity demanded is an increase or decrease in the quantity demanded of goods or services due to change in the price of the good or service itself.

It is important to note that the only factor causing movement along the demand curve is change in the price of the product.

An observational study determined that there is a strong correlation between eating breakfast and weight loss. Can it be determi
mylen [45]

A common misconception in statistics is confusing correlation with causation. If two events are correlated, it merely means that they share the same behaviour over time, but it doesn't imply in any way that those event are related by a common cause, or even worse, that one implies the other.

You can find several (even humorous) counter examples online. For example, if you plot the number of reported pirates assault against the global temperature in the last years, you'll se that temperature is rising (unfortunately...) while pirates are almost disappearing.

One could observe this strong negative correlation and claim that hotter climate has solved the pirate issue. Of course this is a joke, but it explains why you shouldn't confuse correlation with causation.
