What else can I help you with?
Define Sample size?
a number of observations in testing something such as medicine, pills, etc.
What is difference between testing and measuring?
testing is a technique or process used to measure the level of achievement or performance measurement refers to the process of quantifying or assigning a number to performance
Explain how both a stock split and a stock dividend affect the computation of the weighted average number of shares outstanding?
Stock splits and stock dividends both affect the Weighted Average Number of Shares Outstanding in the same way. When it occurs, you act as if it happened at the beginning of the year, and throughout previous periods.
Do extremely high or low scores affect the value of the median?
No, extremely high or low values will not affect the median. Because the median is the middle number of a series of numbers arranged from low to high, extreme values would only serve as the end markers of the values.
How does increasing the number of tosses of a coin affect the average size of the deviation?
It's an important principle or probability. The more coin tosses there are, the more chance there is for an expected outcome.
Does the number of batteries change the brightness of the bulb?
It will if the batteries are connected in series. If they are connected in parallel, the lamp will burn longer, but not brighter.
Does the number of batteries affect the speed of a motor?
The number of batteries can affect the speed of a motor. Increasing the number of batteries can provide more power to the motor, potentially increasing its speed. However, there may be limitations based on the motor's design and the capacity of the batteries.
How does the number of batteries affect the strength of the electromagnet?
The number of batteries affects the strength of the electromagnet by influencing the amount of current flowing through the wire. More batteries can provide a higher voltage and thus increase the current, which in turn strengthens the magnetic field produced by the electromagnet.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
Factory workers test 60 batteries. 24 batteries are defective. What is the experimental probability that a battery is defective?
Just divide 24 (the number of defective batteries) by 60 (the total number).
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
If a circuit has two AA alkaline batteries how many joules of energy does each coulomb of charge?
You need to multiply the number of coulombs by the number of volts. If the two batteries are in series, then you can add the voltage of both batteries.
What is the apparent brightness of a star as represented by a number on a logarithmic scale?
The apparent brightness of a star is represented by its apparent magnitude, which is a logarithmic scale used to measure the brightness of celestial objects as seen from Earth. The lower the apparent magnitude number, the brighter the star appears in the sky. Each increase of one magnitude corresponds to a brightness factor of 2.5.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
Are there environmental benefits to using rechargeable batteries?
Yes, there are big environmental benefits to using rechargeable batteries, especially that there won't be as much toxic materials in waste dumps, because it cuts down on the number of batteries throw away. Rechargeable batteries are extremely environmentally friendly, because they cut down on the number of batteries disposed of each year.
What are the precise benefits to the environment of using rechargable batteries?
You will take up less resources by reducing the number of batteries manufactured.
How many batteries are needed to power a robot?
The number of batteries needed to power a robot will depend on the design of the specific robot.
