Both of these formulas were found on page 225 in Mathematics in Our World (Bluman, 2005). Problem #37 • This sequence is geometric • Ending balance is $814.45 STEPS/CALCULTATIONS YOU PERFORMED TO REACH THE ANSWER: To find the ending balance, the formula of An = a1(rn-1) will be used. The initial balance is $500, the interest is 5%, and the time span is 10 years. 5% will be listed as 1.05 as the initial balance is 100% plus 5% interest, so 105% is written 1.05. The number of terms is n=10, the first term is a1=525, the common ratio is r = 1.05.
70*$15=1,050 and 60*$10=600 which brings the total to $1,650. With 1,650-1,900 = 250. 250/$5 = 50 which means there were 50 $5 tickets sold. So the Total is 70-$15 tickets, 50-$5, and 60-$10 tickets sold. 7) Find the sum of three whole numbers is 7 X , 2x=1, ( 6-3x) (6-3x)+x=(2x+1)-3 6-2x=2x-2 8=4x X=2.
Given is the augmented matrix of a system of equations: 1 5 6 2 7 1 3 5 1 5 7 13 Write the new form of the augmented matrix after the following row operations. R1 r1 r3 , R2 r2 7r3 6. Four times the number of white marbles exceeded 9 times the number of red marbles by 10. The ratio of blue marbles to red marbles was 3 to 1. There is a total of 65 marbles of all 3 colors.
It is four octets of numbers from 0-255 represented in decimal form. Class A always has the first bit of their address set to 0. They have an 8 bit network mask that is why they leave it zero so they can have 7 bits for the network portion. They have 128 possible networks. Class B addresses always has the first bit set to 1 and their second bit set to 0.
Data available is Plant Total Bricks produced in 50 days S (standard deviation) x̄ (mean) Memphis 7484500 3402.46 149690 Birmingham 6902350 3364.68 138047 Hypothesis test In a hypothesis test we assume Ho to be true and try to find evidence that shows otherwise. We test the claim using a level of confidence. Suppose we take 5% level of significance in this case. We choose a test statistic, choose a rejection region, test the statistic and make a conclusion. State Hypothesis Ho : µ1 - µ2 =< 10000 (µ1 and µ2 are the mean bricks produced in a day in Memphis n Birmingham plants) H1 : µ1 - µ2 > 10000 (Ho is null hypothesis and H1 is alternative hypothesis) Choosing a Test Statistic Whenever sample size is greater
