Answer: take a protractor to the unkown sides to find the angle degrees and to check add them up and see if it is 360 degrees
Step-by-step explanation:
180% = $270
60% = $90
10% = $15
100% = $150
Original price = $150
The answer is B. It is also called as the stock market index, it is an estimation of the value of a section of the share trading system. It is processed from the costs of chose stocks. It is an instrument utilized by speculators and money related chiefs to portray the market and to think about the arrival on particular ventures.
1kg=1000g so if it would be 80% it would be 20% left since 1000 is a proper percent we could determine that 800g
Is lost and we have 200g left or 2/10KG
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 25235
For the alternative hypothesis,
µ > 25235
This is a right tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 100,
Degrees of freedom, df = n - 1 = 100 - 1 = 99
t = (x - µ)/(s/√n)
Where
x = sample mean = 27524
µ = population mean = 25235
s = samples standard deviation = 6000
t = (27524 - 25235)/(6000/√100) = 3.815
We would determine the p value using the t test calculator. It becomes
p = 0.000119
Since alpha, 0.05 > than the p value, 0.000119, then we would reject the null hypothesis. There is sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area.
