The distribution of SAT scores of all college-bound seniors taking the SAT in 2014 was approximately normal with a mean of 14971
RideAnS [48]

Answer:

P(X<1200) is 0.8212

Step-by-step explanation:

Test statistic (z) = (X - mean)/sd

X is score of a tester = 1200

mean = 1497

sd = 322

z = (1200 - 1497)/322 = -297/322 = -0.92

The cumulative area of the test statistic is the probability that X<1200. The cumulative area is 0.8212.

Therefore, P(X<1200) = 0.8212

jenny borrowed $500 for 5 years at 4% interest compounded annually. what is the total amount she will have paid when she pays of
alexdok [17]
Use the formula for compound interest,  
  
A=P(1+ \frac{r}{n})^{nt}  
  
Where P is the starting amount (500$), r is the rate of interest (0.04), n is the number of times the interest is compounded per unit (1 per year), and t is the amount of time it is compounded (5 years).  
  
Now, plug it into the formula:  
  
A=500(1+ \frac{0.04}{1})^{5}  
  
Do the math, and your answer is she must pay <span>608.32$ when she pays her debts.</span>
