Answer:

Step-by-step explanation:

P(A) = 144/200 = 0.72

P(B) = 141/200 = 0.705 = 0.71

The two probabilities are similar but different. From the table, a large number of students who play guitar are also left-handed: 116. So the two probabilities are NOT independent - if u are left-handed, u are more likely to play guitar n vice versa.

Answer:

Step-by-step explanation:

P(A) = Probability of a student knowing how to play guitar

= no. of students who know how to play guitar / total no. of student

= 144/200

= 0.72

P(B) = Probability of a student is left-handed

= no. of students who is left-handed / total no. of student

= 141/200

= 0.705

P(A) and P(B) are calculated to be two real numbers and do not depend on each other. So event A and B are independent.

This is a 30-60-90 right triangle with the shorter leg having a length of 5.

To find the length of x, we must find the length of the longer leg of the right triangle. To do that, we must multiply the shorter leg by the square root of 3.

$x=5* \sqrt{3} =5 \sqrt{3}$

This is the simplest radical form. Hope this helps! :)

Barry wants to take out a loan from his bank for $1,000 to buy a bicycle. The interest rate on the loan from the bank is 9%. He

tekilochka [14]

Answer:

The amount that Barry would pay in interest for his loan is $15.05.

Step-by-step explanation:

To calculate this, we first calculate the monthly required fixed payment using the formula for calculating loan amortization as follows:

P = (A * (r * (1 + r)^n)) / (((1+r)^n) - 1) .................................... (1)

Where,

P = Monthly required fixed payment = ?

A = Loan amount = $1,000

r = monthly interest rate = 9% / 12 = 0.09 / 12 = 0.0075

n = number of payment months = 3

Substituting all the figures into equation (1), we have:

P = ($1,000 * (0.0075 * (1 + 0.0075)^3)) / (((1 + 0.0075)^3) - 1)

P = $338.35

Therefore, we have:

Total repayment = P * 3 months = $338.35 * 3 = $1,015.05

Interest amount = Total repayment - Loan principal = $1,015.05 - $1,000 = $15.05.

Therefore, the amount that Barry would pay in interest for his loan is $15.05.
