19. In June, Cory begins to save money for a video game and a TV he wants to buy in Decembe
He starts with $24. Each month he plans to save 10% more than the previous month. How
much money will he have at the end of December?
O$203.74
O$177.34
O$227.69
O$185.22

Answers

Answer 1

The amount of money that he should have at the closing of December should be $227.69.

The correct answer choice is option C

How to find total savings?

Given that,

Starting amount = $24

And, it plans to save 10% more as compared to the last month.

The amount of money that he should have at the closing of December can be solved using the concept of geometric sequence.

First term, a = $24

Common ratio, r = 1.10

Number of terms, n = 7

So,

Sn = a1×(r^n -1)/(r -1)

S7 = 24×(1.10^7 -1)/(1.10 -1)

= (24×0.948717) / 0.10

= $227.69

The total amount Cory will have saved by the end of December is approximately $227.69

Answer 2

Answer:

  (c)  $227.69

Step-by-step explanation:

The amounts Cory will be adding to his account comprise a geometric series with first term $24 and each successive term 10% more, or 1.10 times the previous term. The total amount Cory will have saved by the end of December is the sum of 7 terms of the series.

__

sum of geometric series

The sum of ...

  24 +1.10×24 +1.10²×24 +... +1.10⁶×24

is given by the formula ...

  Sn = a1×(r^n -1)/(r -1)

where a1 is the first term (24), and r is the common ratio (1.10).

formula application

For the series representing Cory's deposits, we have ...

  S7 = 24×(1.10^7 -1)/(1.10 -1) = 24×0.948717/0.10 ≈ 227.69

At the end of December, Cory will have about $227.69.

Step-by-step explanation:

To calculate the mean, in this situation, you first add up the game scores and divide it by the amount of games.

So, first we add 24+17+28+19+23+20+13+19 = 163

Because there are 8 games, we do 163 / 8 = 20.375

You play a game that requires rolling a six-sided die and then randomly choosing a colored card from a deck containing 3 red cards, 6 blue cards, and 8 yellow cards. Find the probability that you will roll a 5 on the die and then choose a red card.

Answers

The probability of getting a red card and rolling a 5 is = 3/85

How to find the probability?

First, we want to find the probability of rolling a 5.

There are 6 outcomes on the six-sided die, so the probability of getting a particular value is:

P = 1/5.

Then, the probability of randomly drawing a red card is given by the quotient between the number of red cards and the total number of cards:

P' = 3/(3 + 6 + 8) = 3/17

The joint probability is given by the product between the individual probabilities:

Which is the best way to buy a car?

Generally, the equation for the monthly loan payment is mathematically given as

[tex]R=\frac{\frac{iP}{N}}{1-(\frac{1}{N})^{NY}}[/tex]

Therefore

[tex]R=\frac{\frac{0.024*32000}{12}}{1-(\frac{0.024}{12}+1)^{-12*5}}[/tex]

R=566.51

Hence the total payment is

This function can also be written as

[tex]\rm f(x) = \dfrac{3 x^2}{x^{2}-2^2}\\\\\rm f(x) = \dfrac{3 x^2}{(x+2)(x-2)}[/tex]

Vertical asymptotes are defined when the denominator of a rational function tends to zero.

To find the equation/s let the denominator equal zero.

Denominator tends to zero for x = -2 and x = +2

Horizontal Asymptote is when the function f(x) is tending to zero.

for x = +∞ and x = - ∞

Let the rational function [tex]f(x)= \dfrac{mx^a}{nx^b}[/tex]  where  and a and b are degree of numerator and denominator.

If a < b , then the y axis y = 0 is a horizontal asymptote.

If b = a then horizontal asymptote is the line y = p/q

Here the value is b = 2 and a = 2

Since b = a the horizontal asymptote is the line

y = m/n  where m = 3 and n = 1

Therefore y = 3
