For simple interest, the equation is
i = prt
interest = (principal/amount deposited) • (rate in decimal form) • (time in years)

To change the 2 1/2% interest to decimal form, first it becomes 2.5% interest, then divide by 100 (moving the decimal place 2 to the left), = 0.025

To calculate interest after 1 year, the equation blanks they gave you left off the time, which is 1, because it won’t change the equation.

0.025 • 250 = $6.25

Interest after 8 years:

i = (250)(0.025)(8)
i = $50

Hope this helps. Let me know in the comments if you have questions, or want to include the rest of the “convince me” section.

A test consists of 10 true or false questions. To pass the test a student must answer at least eight questions correctly. If the

<h3>The probability of student passing the quiz with at least 50% of the questions correct is 0.05457.</h3>

Step-by-step explanation:

Here, the total number of T/F question = 10

The minimum answers needed correctly answered = 8

So, student needs to answer at least 8 questions correctly.

Here, the possibility of answering a question correctly = $(\frac{1}{2})$ = p = 0.5

Also, the possibility of answering a question wrong = $(\frac{1}{2})$ = q = 0.5

Now, to pass he needs to answer 8 or more ( 8 , 9 or 10) answers correctly.

P(answering 8 correct answer) = $^{10}C_8(p)^8(q)^2 = ^{10}C_8(0.5)^8(0.5)^2 = 0.0439$

P(answering 9 correct answer) = $^{10}C_9(p)^9(q)^1 = ^{10}C_9(0.5)^9(0.5)^1 = 0.0097$

P(answering 10 correct answer) = $^{10}C_{10}(p)^{10}(q)^0 = ^{10}C_{10}(0.5)^{10}(0.5)^0 = 0.00097$

So, the total Probability = P(8) + P(9) + P(10)

= (0.0439) + (0.0097) + (0.00097)

= 0.05457

Hence, the probability that the student passes the quiz with at least 8 of the questions correct is 0.05457.

Sam saved $40 each month for 3 years. Then, he spent 65% of his savings on a cruise. How much of his savings was left? A. $420 B

VLD [36.1K]

Answer:

$588 was left

Step-by-step explanation:

Since it was $40 for 3.5 years, and there are 12 months in a year, we do: (3*12+6)*40=1680
65%= 13/20
13/20 * 1680
Sam paid $1092
1680 - 1092 = 588
