A scientifically valid hypothesis must be testable and falsifiable. Testable means that it can be evaluated through observations or experimentation. Falsifiable means that it's possible to design an experiment whose results would prove the hypothesis to be incorrect.
Within the scientific community, a hypothesis is considered to be scientifically valid only if it is testable and falsifiable. When we say a hypothesis is testable, it means that it can be evaluated through observations or experimentation, using the scientific method. An example of this could be the hypothesis 'If I water my plants more, they will grow faster.' This hypothesis is testable because we can carry out an experiment to confirm or refute it.
On the other hand, a hypothesis is said to be falsifiable if it is possible to design an experiment whose outcome could prove the hypothesis to be incorrect. For example, the hypothesis 'All swans are white' is falsifiable because finding just a single swan of a different color would falsify the hypothesis. However, it's important to note that falsifiable doesn't mean the hypothesis is incorrect, rather it means that it's possible to prove it's incorrect through testing.

A hypothesis must be testable and falsifiable in order to be considered scientifically valid. This means that it can be tested through experimentation or observation, and can be proven false if the experimental results contradict it.
A hypothesis must be testable and falsifiable to be scientifically valid. Being testable and falsifiable means that it can be tested through experimentation or observation and can be proven false if the experimental results contradict it. Testability and falsifiability are key requirements in scientific research as they allow for the advancement of knowledge and the development of more accurate explanations of natural phenomena.

Answer:
Length = 14
Width = 7
Step-by-step explanation:
Length of a rectangle is twice its width.
let, the width be x, so the length becomes 2x
now the perimeter is 42, and we know the formula to find the perimeter is 2(length+width)
so, 2(2x+x)=42
or, 2×3x=42
or, 6x=42
or, x=7
so the width is 7 and the length is, 2×7 = 14

Answer:
Step-by-step explanation:
salary per year=1200×12=14400
let the sale be $ x
14400+38 % of x=35,000
38 % of x=35,000-14,400=20,600
x=20,600 \times \frac{100}{38}=$ 54210.53
To earn $35,000 per year, the sales rep must generate approximately 54,210 sales.
To find out how many sales the wholesale food sales rep must generate in order to earn $35,000 per year in total compensation, we need to set up an equation based on the given information. Let's assume the sales generated by the rep are 'x'. The total compensation can be calculated as:
Total Compensation = Base Salary + Commission
$35,000 = $1200/month + 0.38x
Now, we can solve this equation to find 'x', the number of sales needed. First, let's convert the monthly base salary to yearly:
$1200/month * 12 months = $14,400/year
Substituting this value into the equation:
$35,000 = $14,400 + 0.38x
Now, we can isolate 'x' by subtracting $14,400 from both sides of the equation:
$20,600 = 0.38x
Finally, divide both sides of the equation by 0.38:
x = $20,600 / 0.38 = 54,210
Therefore, the wholesale food sales rep must generate approximately 54,210 sales in order to earn $35,000 per year in total compensation.
