Tan is opposite divided by adjacent and then square root the division answer
The total value of the goods and services produced in the nation in a year is called Gross National Product or Gross Domestic Product of that country
With a proper fraction, the whole number would get smaller
<span>So we wan't to know how much would 14 bags of seeds cost if three bags cost 14.16$. What we wan't first is the price of only one bag of bird seeds and lets call it x. To get that we need to divide the cost of three bags of seeds by 3 and we get that x=14.16$/3=4.72$. So now that we know how much one bag of seeds costs we can simply multiply it by 14 and get our answer: 14*4.72$=66.08$</span>
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 ≥ 50000
For the alternative hypothesis,
µ < 50000
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = lifetime of the tyres
µ = mean lifetime
σ = standard deviation
n = number of samples
From the information given,
µ = 50000 miles
x = 45800 miles
σ = 8000
n = 29
z = (50000 - 45800)/(8000/√29) = - 2.83
Looking at the normal distribution table, the probability corresponding to the z score is 0.9977
Since alpha, 0.05 < than the p value, 0.9977, then we would accept the null hypothesis. Therefore, At a 5% level of significance, the data is not highly consistent with the claim.
