Liz flips a coin 60 times. The coin lands heads up 42 times and tails up 18 times. Complete each statement. The theoretical prob
alukav5142 [94]

Answer: The theoretical probability of the coin landing heads up is 0.7

Step-by-step explanation:

Hi, to answer this question we simply have to divide the number of times that the coin lands heads up (42 times) by the number of times that the coin was flipped:

Mathematically speaking:

42 /60 = 0.7 (decimal form)

The theoretical probability of the coin landing heads up is 0.7

For  the or percentage form we simply multiply the result by 100:

0.7 (100) = 70%

Andy is considering taking a loan to remodel his kitchen. He is offered a loan by his bank for five years and an annual interest
Aleksandr-060686 [28]

Using compound interest, it is found that the maximum amount of money he can borrow is of $8,700.

------------------------

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

  • A(t) is the amount of money after t years.
  • P is the principal(the initial sum of money).
  • r is the interest rate(as a decimal).
  • n is the number of times that interest is compounded per year.
  • t is the time in years.

Maximum <u>monthly payments of $200 per month per five years</u>, thus:

A(t) = 5 \times 200 \times 12 = 12000

  • Interest rate of 6.5%, thus r = 0.065.
  • Monthly payments, thus n = 12.
  • Five years, thus t = 5.
  • The <u>amount he can borrow </u>is the principal.

A(t) = P(1 + \frac{r}{n})^{nt}

12000 = P(1 + \frac{0.065}{12})^{60}

1.38282P = 12000

P = \frac{12000}{1.38282}

P = 8678

To the nearest 100, $8,700.

The maximum amount of money he can borrow is of $8,700.
