Answer:
360 degrees in total.
Step-by-step explanation:
We are given that the m∠1 is 145 degrees, and because ∠1 and ∠2 form a straight line we can tell that 180-145 = 35.
So now here's what we know:
m∠1 = 145
m∠2 = 35
After that, we need to look at ∠5 and ∠6.
One thing we can notice right away is that ∠5 and ∠6 should measure the same as ∠1 and ∠2 (respectively) because they are corresponding angles.
Now we will add them all together to find the sum of all four angles.
m∠1 = 145 + m∠2 = 35 = 180
m∠5= 145 + m∠6 = 35 = 180
180 + 180 = 360
Answer:
The 80% confidence interval for the population proportion of disks which are defective is (0.059, 0.079).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
Suppose a sample of 1067 floppy disks is drawn. Of these disks, 74 were defective.
This means that 
80% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 80% confidence interval for the population proportion of disks which are defective is (0.059, 0.079).
Mobile payments are payment transactions done with the help of a mobile phone. Think Venmo, Square Cash and Gogle Wallet, used to transfer money and even to shop at participating retailers – all with the tap of screen. According to a recent global study on mobile payment transactions, the mobile payments market was worth $550 billion in 2015 and is expected to grow more than 39% by 2020. That is explosive growth by any calculation.
But within all the buzz and investment that is flowing into this industry lies a cautionary tale, one that AnnaMaria Lusardi, director of the Global Financial Literacy Excellence Center (GFLEC) at George Washington University in Washington, D.C., explains like this: “We can make payments with the touch of a button, but the impact of this rapid innovation is not being examined.”
