The simple interest rate that you are charged, based on the loan amount and the period of the loan, is 3. 5 %
How to find the simple interest rate ?Borrowers must pay lenders simple interest as a fee in exchange for a loan. Compound interest is excluded from the calculation and just the original principal is used. Simple interest applies to all loans, not just specific ones. Additionally, it refers to the kind of interest that banks give their customers on their savings accounts.
Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.
To find the simple interest rate, find the simple interest charged per year to be:
= 175 / 2
= $ 87. 50
Then , the simple interest rate would be:
= Simple interest per year / Loan amount
= 87. 50 / 2, 500
= 3. 5 %

The seventh grade class supplied bags of snacks and beverages for the school dance. They supplied 50 more beverages than bags of snacks. The dance was supplied with a total of 400 items. How many of each were supplied.
a) Define the variable(s)
b) Write a system of equations for the situation.
Answer:
a) let 's' = number of bags of snacks
b) let 's+50' = number of bags of beverages
s + s+50 = 400
Step-by-step explanation:
a) let 's' = number of bags of snacks
b) let 's+50' = number of bags of beverages
s + s+50 = 400
solve:
2s + 50 = 400
2s = 350
snacks = 175
beverages = 175+50 or 225

prove by the sum of arithmetic induction that the sum of the first n terms of a n arithmetic sequence
The sum of the first n terms of an arithmetic sequence can be proven using the principle of induction. We assume the formula holds for n = k, and then show it holds for n = k+1, thus showing it holds for all values of n.
The sum of the first n terms of an arithmetic sequence can be determined using the formula S_n = (n/2)(a_1 + a_n), where a_1 is the first term and a_n is the nth term.
We can prove this formula using the principle of induction.
Base Case: Let n = 1. Then S_1 = (1/2)(a_1 + a_1), which simplifies to S_1 = a_1. This is the same result we would get if we added the first term of the sequence.
Inductive Step: Assume that the formula holds for n = k.
Then S_k = (k/2)(a_1 + a_k).
Now consider n = k+1.
S_k+1 = (k+1/2)(a_1 + a_k+1)
= (k/2)(a_1 + a_k) + (1/2)(a_1 + a_k+1)
= S_k + (1/2)(a_k+1 - a_1)
= S_k + (1/2)(a_k+1 - a_k) + (1/2)(a_k - a_1)
= S_k + (1/2)(a_k+1 - a_k) + [S_k - (k/2)(a_1 + a_k)]
= (k+1/2)(a_1 + a_k+1)
= S_k+1
Therefore, we have shown that if the formula holds for n = k, then it also holds for n = k+1. By the principle of induction, the formula holds for all n.

What is the best approximation of the solution to the system to the nearest integer values X minus Y equals negative 65X plus 3Y equals 24
The best approximation of the solution to the system to the nearest integer values X minus Y equals negative 65X plus 3Y equals 24 are x = 43 and y = 22
How to determine the solutionFrom the information given, we have the expressions;
X minus Y equals negative 65X plus 3Y equals 24This is represented as;
x - y = -65
x + 3y = 24
Make 'x' the subject from equation 1
x = -65 + y
Now, substitute the expression into equation (2), we get;
-65 + y + 3y = 24
collect the like terms
4y = 24 + 65
Add the like terms
4y = 89
Divide the values by the coefficient of y
y = 89/4 = 22
Substitute the value in eqation3
x = -65 + 22

Using commutative property of addition, the expression 3T 1,892 lb + 1,325 lb is equal 4.5T, 217 lb
What is Addition of ExpressionA mathematical procedure called adding expressions entails merging two or more expressions to create a new expression. A reduced version of the original expressions is produced by adding expressions, which works similarly to adding integers.
We merge similar phrases while adding expressions. When a variable is raised to the same power, terms are said to be like terms. Because they both have the same variable (x) raised to the same power, for instance, 2x and 3x are similar phrases (1).
It's crucial to remember that the commutative characteristic of addition ensures that the order of the terms has no impact on the outcome when adding or subtracting expressions.
In conclusion, adding expressions is a mathematical operation that combines two or more expressions to create a new expression; it is comparable to adding integers. We merge similar phrases while adding expressions. When a variable is raised to the same power, terms are said to be like terms. The commutative property of addition accounts for the fact that the outcome is unaffected by the order of the terms.

T/F. In a certain board game, a player rolls two fair six-sided dice until the player rolls doubles (where the value on each die is the same). The probability of rolling doubles with one roll of two fair six-sided dice is 16.
As per the concept of probability that it takes three rolls until the player rolls doubles is 0.11574 and this can be determined by using the given data.
In math the term probability of an event is defined as nothing but a number between 0 and 1 where zero shows the impossibility and one shows the certainty.
Here we have given that a certain board game, here the player rolls two fair six-sided dice until the player rolls doubles.
And here we know that the probability of rolling doubles with one roll of two fair six-sided dice is 1/6.
Here first we need to determine the probability of rolls to obtain doubles in each roll.
That can be calculated as ,
=> 1 - 1/6 = 5/6
Then the fails in the second roll is calculated as,
=> 1 - 1/6 = 5/6
Then the third roll the player rolls doubles that is calculated as,
=> 1/6
So, the probability of requiring 3 rolls until getting doubles will be calculated as
=> 5/6 x 5/6 x 1/6
=> 25/216
When we simplify this one then we get,

Jai has a 28% free throw rate in basketball. That means when he shoots a free throw he makes a basket 28% of the time. Jai shoots 120 free throws in a season. How many baskets is he likely to make? Use benchmark percents of 1% and 10% to help you determine the answer.
Answer:
34 successful free throws out of 120
Step-by-step explanation:
We can use the 28% free throw rate to predict Jai's success in shooting 120 free throws. If the 28% was calculated from throws made under similar circumstances (e.g., during an actual game), then we can predict that he'll also hit 28% of the 120 attempts:
Likely free throw successes = (28%)*(120)
(0.28)*(120) = 33.6 successful free throws out of 120. We need to round 33.6 to the nearest whole number, which makes it 34 successful free throws out of 120.
Amy works for a company that produces plastic lids and cups for restaurants. She wants to use a one-sample zzz interval to estimate what proportion of lids produced in a day have a defect that makes them not fit the cups. She takes a random sample of 100100100 lids from the more than 1{,}0001,0001, comma, 000 total lids produced that day and finds 555 lids in the sample with this defect.
Amy can use a one-sample z-interval to estimate the true proportion of lids in the population of 1,000,000 that have the defect.
What is sample?Sample can refer to an example of a particular item or type of thing. It can also refer to a section of a population that is chosen in order to represent the whole group. When used in research, samples are used to make conclusions about a population as a whole. Samples are also often used to test products or services in order to assess their quality or performance.
First, she will calculate the sample proportion of lids with the defect by dividing the number of lids in the sample with the defect (555) by the total number of lids in the sample (100,000). This sample proportion is 0.00555.
Next, Amy will calculate the standard error of the sample proportion. This is calculated by taking the square root of the sample proportion multiplied by (1 - sample proportion) divided by the sample size. The standard error for this sample is 0.00023.
Finally, Amy can calculate the one-sample z-interval. This is done by subtracting the standard error from the sample proportion and adding it to the sample proportion. This gives a one-sample z-interval of 0.0053 to 0.0058.
This one-sample z-interval tells Amy that she can be 95% confident that the true proportion of lids with the defect in the population of 1,000,000 is between 0.0053 and 0.0058.
