The required number of year at 2.5% simple interest on a quarterly basis is 4%.
What is simple interest on quarterly basis?if the interest rate is 8% each year, however the estimation being referred to requires a quarterly financing cost, then, at that point, the significant loan cost is 2% per quarter. The 2% per quarter is comparable to a straightforward loan fee of 8% each year
According to question:
We have,
Interest in 3 months = 2.5%
So, interest in one year = 4(2.5%) = 10%
Principle amount = $700
Final amount = $980
To calculate number of years,
total interest = 980 - 700 = $280
Let number of years be t.
Then,
$280/t = 10% of $700
t = $280/$70 = 4 years
Thus, required years 4.

o of the four expressions x y, x 5y, x – y, and 5x – y are chosen at random, what is the probability that their product will be of the form of x 2 – (by) 2 , where b is an integer?
The probability of the product of the given expressions is in the form of x² - (by)² is equal to 1/6.
As given in the question,
Given four expressions are:
( x + y ) , ( x + 5y ) , ( x - y ) and ( 5x - y )
Product of any two expression to have two degree expressions :
( x + y )( x + 5y ) = x² + 6xy + 5y²
( x + y )( x - y ) = x ² - y²
( x + y )( 5x - y ) = 5x² + 4xy -y²
( x + 5y )( x - y ) = x² + 4xy -5y²
( x + 5y )( 5x - y ) = 5x² + 24xy -5y²
(x - y) ( 5x - y) = 5x² - 6xy + y²
Total number of possible outcome of the product with degree 2 = 6
Favourable outcomes in the form of x² - ( by )² is x² - y² = x² -(1y)²
Here b = 1 is an integer.
Number of favourable outcomes = 1
Required probability = 1/6
Therefore, the probability of the product in the form of x² - ( by )² is equal to 1/6.
The complete question is:
If two of the four expressions x + y, x + 5y, x – y, and 5x – y are chosen at random, what is the probability that their product will be of the form of x2 – (by)2, where b is an integer?

Answer:
-4
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
g(x) tells us what the variable is and what variable should be replaced with a value.
g(1) tells us the value that will replace x.
Plug in 1 to the equation:
-5(1) + 1 = g(1) (multiply)
-5 + 1 = g(1) (combine like terms)
-4 = g(1)
Therefore, g(1) is equal to -4

on a standardized test with a normal distribution, the mean was 64.3 and the standard deviation was 5.4. what is the best approximation of the percent of scores that fell between 58.9 and 75.1?
the best approximation of the percent of scores that fell between 58.9 and 75.1 is 4.
The mathematical average of a group of two or more numbers is called the mean. There are two different sorts of means that can be calculated: the arithmetic mean and the geometric mean. The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of integers in the set.
Find the difference between these two figures and the mean, divide it by the standard deviation of 5.4, and you will know how many standard deviations 75.1 and 61.5 are above and below the mean:
(75.1−64.3)/5.4

According to the empirical rule, 95% of data are within two standard deviations of the mean.

In a periodic review system when an order is placed every 14 days, the uncertainty period is 22 days.
Lead time is the time that passes from the start to the conclusion. It helps in measuring the time taken to complete a project. It varies from industry to industry.
It is normally calculated as:
Lead time = processing time + post-processing time.
Given,
lead time = 8 days
Order place date = 14 days

a multiple choice exam has a mean of 100 and a standard deviation of 13. about what percent of people would be expected to score 115 or more on the exam?
1.15 percentile of people would be expected to score 115 or more
What is Standard Deviation?
A standard deviation (or σ) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out.
Solution:
Mean = 100
Standard Deviation = 13
To solve the given problem we need to calculate the Z - Score
Z = X - Mean / Standard Deviation
P(X > 115)
Z = 115 - 100 / 13

The definition of perimeterThe perimeter of a shape is the entire length of the shape's boundary as used in geometry. A form's perimeter can be calculated by adding the lengths of all of its sides and edges. In order to calculate it, linear distances such as centimeters, meters, inches, or feet are used.
Here
This is because 15x15 =225
8x8 = 64
225+64=289 and
the square root of 289 is 17 and that is the diameter of the circle and the hypotenuse of the triangle and since the kite has two congruent sides which are both radii or can be written as half of a diameter times two would be the same as the length of the diameter which is17+the two bottom sides (which are both 5 and 5 )

Answer:
Option A for both questions--------------------------
The first questionThe graph indicates the inequality n ≤ 1, since highlighted part is to the left from the 1 and there is a closed circle.
Double both sides to get 2n:
n ≤ 1 ⇒ 2n ≤ 2And add 5 to both sides to get 7:
2n + 5 ≤ 2 + 5 ⇒ 2n + 5 ≤ 7This is matching the option A.
Question 12The graph indicates the inequality p > 2, since highlighted part is to the right from the 2 and there is a open circle.
Multiply both sides by 5 to get 5p:
p > 2 ⇒5p > 10Add 4 to both sides to get 14:
5p > 10 ⇒5p + 4 > 14This is matching the option A.

The histogram's best summary is option (D), "there are a total of 12 snacks with the same amount of sugar."
What is a histogram?While bar charts show categorical variables, histograms show quantitative or numerical data.

It would be ridiculous to try and show all possible values of a continuous variable along an axis.
So, the y-axis displays the number of snacks.
The x-axis displays how much sugar is in each snack.
The histogram's first column reveals that 2 snacks each contain between 220 and 224 mg of sugar.
The second column reveals that around 3 snacks have 224–228 mg of sugar.
The third column reveals that 8 snacks range in sugar content from 228 to 232 mg.
Twelve snacks are identified in the fourth column as having between 232 and 236 mg of sugar.
Twelve snacks are identified in the fourth column as having between 232 and 236 mg of sugar.
The fifth column reveals that 11 snacks range in sugar content from 236 to 240 mg.
Three snacks are shown to contain between 240 and 244 mg of sugar in the sixth column.
According to the seventh column, 2 snacks contain 244–248 mg of sugar.
The total number of observations is 41 nibbles, or 2+3+8+12+11+3+2.
So, the best statement that describes the histogram is "The most snacks with the same quantity of sugar are 12 in total."
