Answer:
$2647.13
$2648.08
Step-by-step explanation:
To solve for the value of each loan we will use the formula:
Let's break down the variables that we have.
P = $2,600
r = 7.25% or 0.0725
r2 = 7.50% or 0.0750
t = 90 days
Now since we're computing for two different types of interest, let's take it one at a time.
First the State Saving and Loan.
In this situation we are solving for ordinary interest, where we compute with the total number of days are 360
The maturity value of State Savings and Loan is $2,647.13.
Now let's move on to the Security bank.
The security bank charges 7.5% exact interest. For exact interest we use 365 days.
The maturity value of the Security bank is $2,648.08.
The answer would be 10x+4y-13 which can also be written as 10x+4y=13.
Answer: 10x - 15y because 5(2x) = 10x and 5(-3y) = -15y
Answer:
And we can use the z scoe formula given by:
And if we find the z score for the limits we got:
And this probability is equivalent to:
Step-by-step explanation:
For this case we can define the random variable X as "number of miles between services" and we know the following info given:
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
From the central limit theorem we know that the distribution for the sample mean is given by:
We select a random sample size of n =44. And we want to find this probability:
And we can use the z scoe formula given by:
And if we find the z score for the limits we got:
And this probability is equivalent to:
Answer:
x > 9/5
Step-by-step explanation:
2/3 x - 1/5 > 1
15 × 2/3x - 15 × 1/5 > 15 × 1
10x - 3 > 15
10x > 18
x > 18/10
x > 9/5
