if p and n are positive integers and p > n, what is the remainder when p2 – n2 is divided by 15 ?

Answers

Answer 1

If p and n are positive integers and p > n. 0, 1, 5, 6, 9, and 11 are the remainders when p² - n² is divided by 15.

To find the remainder whilst (p² - n²) is split with the aid of 15, we are able to think of the expression p² - n² the usage of the distinction of squares method.

The distinction of squares formula states that a² - b² can be factored as (a + b)(a - b).

Applying this method to p² - n²;

p² - n² = (p + n)(p - n)

Now, we recognize that p and n are positive integers and p > n. This way that p + n and p - n are both advantageous integers.

To locate the remainder whilst (p^2 - n^2) is split through 15, we will take a look at the remainders of (p + n) and (p - n) when divided with the aid of 15.

Let's don't forget the viable remainders when dividing an integer by means of 15:

zero, 1, 2, 3, 4, five, 6, 7, eight, 9, 10, 11, 12, 13, 14

Since p + n and p - n are both high-quality integers, the feasible remainders when dividing them by way of 15 could be:

zero, 1, 2, three, 4, 5, 6, 7, eight, 9, 10, eleven, 12, thirteen, 14

Now, permits take into account the viable products of (p + n) and (p - n) while the remainder is multiplied:

0 * 0 = 0

1 * 14 = 14

2 * 13 = 26 (that's equal to eleven modulo 15)

3 * 12 = 36 (that's equal to six modulo 15)

4 * eleven = 44 (that's equivalent to fourteen modulo 15)

5 * 10 = 50 (which is equivalent to five modulo 15)

6 * 9 = 54 (that is equivalent to nine modulo 15)

7 * eight = 56 (that's equal to 11 modulo 15)

8 * 7 = 56 (that is equivalent to eleven modulo 15)

9 * 6 = 54 (that's equal to nine modulo 15)

10 * 5 = 50 (which is equivalent to 5 modulo 15)

11 * 4 = 44 (that's equivalent to fourteen modulo 15)

12 * 3 = 36 (that is equal to 6 modulo 15)

13 * 2 = 26 (that's equivalent to 11 modulo 15)

14 * 1 = 14

From the above merchandise, we will see that (p + n)(p - n) will have remainders of zero, 1, five, 6, 9, and eleven when divided via 15.

Therefore, the feasible remainders whilst () is split through 15 are 0, 1, 5, 6, nine, and 11.

To evaluate y when x = 2 in the equation y = -1/2x² + 6x + 5, we simply substitute x = 2 into the equation and solve for y:

y = -1/2(2)² + 6(2) + 5

y = -1/2(4) + 12 + 5

registered voters are classified as democrat, republican, or independent. suppose that the percentage of voters registered as democrat and republican is 35% and 40%, respectively. (a) what percent of the registered voters are independent?

Answers

We need to use the fact that the percentages of all three categories must add up to 100%. Therefore, the percentage of independent voters can be found by subtracting the percentages of democrat and republican voters from 100%.
Percentage of independent voters = 100% - 35% - 40% = 25%
So, 25% of the registered voters are independent.
In conclusion, the percentage of independent voters is 25%. This is because the percentages of democrat, republican, and independent voters must add up to 100%. The percentages of democrat and republican voters are given, so we can find the percentage of independent voters by subtracting those from 100%.
Based on the given information, 35% of registered voters are classified as Democrats, and 40% are classified as Republicans. To find the percentage of registered voters who are independent, we need to subtract the total percentage of Democrats and Republicans from 100%.
100% - (35% + 40%) = 100% - 75% = 25%
Therefore, 25% of the registered voters are classified as independent.

Help Will give BRAINLYST How many years will it take mr sanchez to have 10,568.52 in the college fund ,if mr sanchez does not make any deposits or withdrawals

Answers

Answer:

16 years

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where A is the final amount, P is the principal (initial amount), r is the annual interest rate (as a decimal), n is the number of times per year the interest is compounded, and t is the number of years.

In this case, P = $5000, r = 0.05 (since the annual interest rate is 5%), n = 12 (since the interest is compounded monthly), and we need to solve for t when A = $6,568.52.

Plugging in the values, we get:

$6,568.52 = $5000(1 + 0.05/12)^(12t)

Dividing both sides by $5000 and taking the natural logarithm of both sides, we get:

ln(1.313704) = ln(1 + 0.05/12)^(12t)

Using the logarithmic identity ln(a^b) = b ln(a), we can simplify the right side:

ln(1.313704) = 12t ln(1 + 0.05/12)

Dividing both sides by 12 ln(1 + 0.05/12), we get:

t = ln(1.313704) / (12 ln(1 + 0.05/12)) = 16.0

Therefore, it will take Mr. Sanchez 16 years to have $6,568.52 in the college fund, if he does not make any deposits or withdrawals. The answer is 16 years.

What is the angle of the 3rd order bright fringe produced by two slits that are 5.82x10-5m apart if the wavelength of the incident light is 5.04x10-7m?
A. 0.0867o
B. 4.97o
C. 0.260o
D. 15.1o

Answers

We can use the equation for the angle of the bright fringes in a double-slit experiment. The answer is D. 15.1o.

where θ is the angle of the bright fringe, m is the order of the fringe (in this case, m=3), λ is the wavelength of the incident light, and d is the distance between the slits.

Plugging in the given values, we get:

sinθ = (3)(5.04x10^-7m)/(5.82x10^-5m) = 0.260

Taking the inverse sine of both sides, we get:

θ = sin^-1(0.260) = 15.1o

Therefore, the answer is D. 15.1o.


To find the angle of the 3rd order bright fringe, we can use the formula for the double-slit interference pattern:

mλ = d * sinθ

where m is the order number (3 in this case), λ is the wavelength of the incident light (5.04x10^-7 m), d is the distance between the slits (5.82x10^-5 m), and θ is the angle we want to find.

First, rearrange the formula to solve for the angle:

sinθ = (mλ) / d

Now, plug in the given values:

sinθ = (3 * 5.04x10^-7 m) / 5.82x10^-5 m

Calculate the result:

sinθ = 0.02594

Now, find the inverse sine (arcsin) of the result to get the angle:

x

ˉ

. In this case, $\bar{x} = $36.

Identify the sample standard deviation, s. In this case, $s = $15.

Identify the t-critical value, t. The t-critical value is the value that cuts off 2.5% of the distribution in each tail, leaving 95% of the distribution in the middle. To find the t-critical value, we need to know the degrees of freedom, df. The degrees of freedom are calculated as df=n−1. In this case, df=13−1=12.

We can find the t-critical value using a t-distribution table. The t-distribution table shows the t-critical values for different degrees of freedom and different confidence levels. For a 95% confidence level and 12 degrees of freedom, the t-critical value is 2.179.

Calculate the confidence interval. The confidence interval is calculated as follows:

$\bar{x} \pm t \cdot \frac{s}{\sqrt{n}}$

In this case, the confidence interval is:

$36 \pm 2.179 \cdot \frac{15}{\sqrt{13}} = (27.28, 44.72)$

Therefore, a 95% confidence interval for the mean amount spent on a child's last birthday gift is $27.28 to $44.72.

Unlike the traditional IQ test, a group of researchers have designed new IQ questions
testing for the 9 different types of intelligence. The distribution of IQ scores using the new test for high
school students is normally distributed with a mean of 80 points and a standard deviation of 12 points.
Use technology to find the following. (Note: for full credit, write correct probability notation)


(a) Find the probability to 3 decimal places that a high school student chosen at random has an IQ
score between 60 to 75 points, inclusive.

(b) A student will need special attention if the student’s IQ score is below 55 (at most 54) or above
100 (at least 101). What proportion of the high school students will need special attention?
Hint: Look carefully at the bolded phrases.

(c) Mensa International is the largest and oldest high IQ society in the world. Members of this
society are individuals who score at the 98th percentile or higher on this new IQ test. Determine the
cutoff IQ score (it must be a whole number) to be a member of Mensa International.

Answers

(a) The probability of a random high school student having an IQ score between 60 and 75 points is approximately 0.186. (b) About 6.5% of high school students will require special attention based on IQ scores below 55 or above 100 points. (c) The cutoff IQ score to be a member of Mensa International is approximately 105.

To solve these problems, we will use the standard normal distribution, also known as the Z-distribution. We'll need to calculate z-scores and use the z-table or technology to find probabilities.

(a) To find the probability that a high school student chosen at random has an IQ score between 60 and 75 points, inclusive, we need to calculate the area under the normal curve between these two values.

First, we convert the IQ scores to z-scores using the formula:

z = (x - μ) / σ

where x is the value we want to convert, μ is the mean, and σ is the standard deviation.

For 60 points:

z1 = (60 - 80) / 12 = -1.6667

For 75 points:

z2 = (75 - 80) / 12 = -0.4167

Next, we use technology or a z-table to find the probabilities associated with these z-scores:

P(-1.6667 ≤ Z ≤ -0.4167)

Using technology or a z-table, the probability comes out to be approximately 0.186.

Therefore, the probability that a high school student chosen at random has an IQ score between 60 and 75 points, inclusive, is 0.186.

(b) To find the proportion of high school students who will need special attention, we need to calculate the area under the normal curve below 55 points (z ≤ (55 - 80) / 12) and above 100 points (z ≥ (100 - 80) / 12).

P(Z ≤ -2.0833) + P(Z ≥ 1.6667)

Using technology or a z-table, we find the probabilities:

P(Z ≤ -2.0833) ≈ 0.018

P(Z ≥ 1.6667) ≈ 0.047

Adding these probabilities, the proportion of high school students who will need special attention is approximately 0.018 + 0.047 = 0.065.

Therefore, about 6.5% of high school students will need special attention.

(c) To determine the cutoff IQ score to be a member of Mensa International, we need to find the value corresponding to the 98th percentile of the standard normal distribution.

We want to find the IQ score x such that P(Z ≤ z) = 0.98.

Using technology or a z-table, we find the z-score corresponding to a cumulative probability of 0.98 is approximately 2.055.

Now, we solve for x in the z-score formula:

2.055 = (x - 80) / 12

Simplifying and solving for x:

24.66 = x - 80

x = 24.66 + 80

x ≈ 104.66

Therefore, the cutoff IQ score to be a member of Mensa International would be 105 (rounded to the nearest whole number).

Point O is between points M and N on line segment MN. O is the midpoint of line segment MN if
OOM=NM
O ON=NM
O ON OM
O ON+OM = MN

Answers

When point O is between points M and N on line segment MN. O is the midpoint of line segment MN if

O ON + OM = MN

What is midpoint of a line segment?

In geometry the midpoint is the point that divides a line segment into two equal parts

It is the point that is equal distance from both endpoints of the segment.

In this case the endpoints are M and N, the midpoint is point O, which is the point that is halfway between M and N, so that ON = OM. and adding the points returns the original line MN

Therefore, we have that ON + OM = MN
