Answer:
m=12
Step-by-step explanation:
m+7=19
subract 7 from both sides
m=12
The usual formula for finding the amount A of a monthly payment on principal amount P with annual interest rate r over t years is
... A = Pr/(12·(1 -(1+r/12)^(-12t)))
Filling in P=1000, r=.075, t=2, you get
... A = 45.00
The montly payment is $45.00.
_____
The given formula looks nothing like one used to compute the payment, nor is it anything like a formula used to compute interest on such a loan. We cannot figure out how to use it (or if it is even applicable) without knowing the definitions of the variables involved.
<u>Given</u>:
Given that in a game a player draws and replaces a card from a deck 2 times.
The possible outcomes and payouts are given.
We need to determine the expected value for someone playing the game.
<u>Expected value:</u>
The expected value for someone playing the game can be determined by
Simplifying the values, we have;
Dividing the terms, we get;
Adding, we have;
Thus, the expected value for someone playing the game is $8
<span>The answer is 60. Let x be the number we are looking for. So x is 100% and we know that 15 is 25%. Make a proportion: x : 100% = 15 : 25%. Cross the products: x * 25% = 15 * 100%. x * 25% = 1500%. x = 1500% : 25%. x = 60. Thus, 60 is 100%, and 15 is 25% of 60. </span>
In this question it is given that the values of CD and CE are 20 and 32 respectively.
Since the length of CE is greater then of CD, so C and D could not be the end points.
Therefore, either D and E are the endpoints or C and E are the endpoints.
If D and E are the endpoints, then DE is the sum of 20 and 32 which is 52.
And if C and E are the endpoints, then DE is the difference of CE and CD that is 12.
So the possible values of DE are 12 and 52.
