Answer:
40km
hope this helps
have a good day :)
Step-by-step explanation:
Well a circle is 360 degrees and the angle turns 125 of that. a fraction can be considered a ratio of a part of the whole vs the whole and can be written as:
part/whole
So the part is 125 and the whole is 360 so
125/360
This can be reduced by 5
25/72
That is your answer
Answer:
1/10 or 0.1 or 10%
Step-by-step explanation:
Answer:
Formula - y=mx+b
You have $100 and you're increasing it by $20 each month.
m=slope, b= initial value.
Thus, y=20x+100, is your linear equation.
Hope This Helps! :D
Answer:
If we define the random variable X ="time spend by the students doign homework"
And we want to tes t is students spend more than 1 hour doing homework per night, on average (alternative hypothesis), so then the system of hypothesis for this case are:
Null hypothesis:
Alternative hypothesis:
And they wnat to use a sample size of n = 100 and a significance level of 0.05
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
