Answer:

0.675

Step-by-step explanation:

given that Ted is  taking a true-false test. He has a 90% chance of identifying the correct answer to each question. Unfortunately, there is a 25% chance that he will circle the opposite of his intended answer.

For Ted circling the correct answer  to any particular question on this test,

first he has to identify the correct answer and then round the correct answer.

Probability for Ted circles the correct answer to any particular question on this test

= Prob for idenfitying correct answer and rounding correct answer

= P(identify correct answer)*P(rounds of correct answer)

= 0.90 ( 1-0.25)

= 0.675

Tasya [4]

Answer:

Amount = $14,024 (Approx)

Step-by-step explanation:

Given:

Amount received P = $13,500

Rate r = 7% = 0.07

Time t = 15 month = 15/12 = 1.25 = year

Discount rate = 6% = 0.06

Computation:

Maturity value = P[1+rt]

Maturity value = 13,500[1+(0.07)(1.25)]

Maturity value = $14,685.61

Time = 15 month - 6 month

Time = 9 month = 9/12 = 0.75 year

Amount = MV[1-dt]

Amount = 14,685.61[1-(0.75)(0.06)]

Amount = $14,024 (Approx)

PLEASE HELP EXPLAIN!!!!!

I think( so correct me if i'm wrong).....Using the distance formula... D=Rate x Time, you alter it so that it equals time, since you want to find the number of weeks.
Time = Distance/ rate
SInce you start off at 2 and end up with 5, the total distance is 3 (I subtracted 5-2). And rate is already 12% (this is the iffy part, I'm not sure if you change the 12%  in anyway.... but lets move on)

SO Time= 3miles/ 12% which is 1/4 of a week, or possibly.....

Time = 3 miles/ 0.12 which would equal 25 weeks.....

Answer:

draw a number line from 66 to 81

make your minimum 67

lower quartile should be on 70

the median on 77

upper quartile and maximum on 80

(note that your upper quartile and maximum is both on 80 so there won't be an extension as you normally would see on a box plot)

You can search up "box plot" and go on images to see what i mean
