Shkiper50 [21]

I don't know what the "lowest y-intercept means" so if you can reiterate and clarify I'd appreciate it, but if you understand what you're looking for then I assume that a graph would be helpful. An online useful graphing site I like is desmos. Hope I helped.

A bag contains 8 purple marbles & 12 green marbles. You choose one marble out of the bag without looking.

MrRissso [65]

Answer:

1. P(P) = 8/20 = 0.4

2. P(G) = 12/20 = 0.6

Step-by-step explanation:

Given;

Number of green marbles G = 12

Number of purple marbles P = 8

Total T = 12+8 = 20

The probability that you choose a purple marble P(P) is;

P(P) = number of purple marbles/total number of marbles

P(P) = P/T = 8/20 = 0.4

P(P) = 0.4

The probability that you choose a Green marble P(G) is;

P(G) = number of Green marbles/total number of marbles

P(G) = G/T = 12/20 = 0.6

P(G) = 0.6

Amy opened a savings account with $1750 she received for graduation. The account pays 4.3% simple interest. What is the balance

Cerrena [4.2K]

Given:

The principal amount that Amy opened her savings account with is $1750.
The rate of simple interest compounded annually is 4.3%.
The time period for which we calculate the new balance is 6 months.

To Find:

The balance after 6 months.

Answer:

The balance after 6 months will be $1787.625

Step-by-step explanation:

The principal amount that Amy opened her savings account with is $1750. We can denote this by P.

The rate of simple interest compounded annually is 4.3% which we may denote by R.

The time period for which we calculate the new balance is 6 months which can be written as 0.5 years (since the rate of interest is compounded annually, we must consider the time period in terms of years).

The amount of money accrued from the interest can be calculated by the formula

$\frac{PRT}{100}$

Putting in the values given in the question, we have

$\frac{(1750)(4.3)(0.5)}{100} = 37.625$

The amount in the bank account will be the principal amount plus the amount of interest accrued that we have calculated above.

Thus, the balance after 6 months will be 1750 + 37.625 = $1787.625.
