a student is randomly eelected from mr.willets class and that studenr is also in ap satts what is the probability that they are as senior?

Answer:

Step-by-step explanation:

Total Student in a class = 80

No. of students passed = 80*80% = 64

No. of students failed = Total Students in a class - No. of students passed

No. of students failed  = 80-64 =16

The degree of the measure of the exterior angle is 141 3/7°.

the term exterior angle in triangle is defined as angles that are parallel to the inner angles of a polygon but lie on the outside of it

Here we know that A square and a regular heptagon are coplanar and share a common side AD.

And then here we need to find each of the interior angle of the regular heptagon.

As we all know that here we have to use the formula that gives the interior angle measure for a regular polygon with any number of sides is 180(n-2)/n where n is the number of sides.

According to the given formula here we have a regular heptagon's interior angle measures is calculated as

=> 180(7-2)/7 = 128 4/7.

Here we also know that the angle A and D would be 128 4/7 degrees.

Here the next step is to Find angle BAC.

For that here we have to know that a square's interior angle is 90 degrees and a heptagon's is 128 4/7 degrees.

Now we have to subtract those from 360 degrees to find angle BAC then we get the expression like the following,

=> Angle BAC = 360 - (angle A + 90)

=> 360 - (128 4/7 + 90)

When we simplify this one then we get the resulting value as,

=> 360 - 218 4/7 = 141 3/7 degree

m = the slope of the curve at x=3 and b = the y-intercept at x=3. Therefore, the approximate value of y at x=2

We can use the local linearization of the curve to approximate the value of y at x=2.

The local linearization of the curve is given by the equation y = mx + b, where m is the slope of the curve at x=3 and b is the y-intercept at x=3.

Let m be the slope of the curve at x=3 and b be the y-intercept at x=3.

The slope of the curve at x=3 can be found by calculating the derivative of the curve at x=3.

The y-intercept at x=3 can be calculated by substituting x=3 into the equation of the curve and solving for y.

Therefore, m = the slope of the curve at x=3 and b = the y-intercept at x=3.

Substituting the values of m and b into the equation of the local linearization, we get the equation y = mx + b.

Substituting x=2 into the equation, we get y ≈ 0.5 + 1 = 1.5.

Therefore, the approximate value of y at x=2

The null hypothesis would be H0: p <= 0.25 and the alternative hypothesis would be Ha: p > 0.25

The null hypothesis represents the default assumption that there is no significant difference between the proportion of high school couples who believe they will marry their high school sweetheart and the researcher's claim that more than 25% of high school couples believe they will marry.

The alternative hypothesis represents the claim that the researcher wants to test, which is that the proportion of high school couples who believe they will marry their high school sweetheart is greater than 25%.

So, the null hypothesis would be:

H0: p <= 0.25 (where p is the proportion of high school couples who believe they will marry their high school sweetheart)

The alternative hypothesis would be:

The total amount in an account to the nearest cent after 3 years if the interest is compounded annually on an investment of $5600 at 7.65% is $6,986.02

To find the total amount in the account after 3 years, we need to use the formula for compound interest:

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

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

In this case, P = $5600, r = 0.0765, n = 1 (because the interest is compounded annually), and t = 3. Plugging these values into the formula gives:

A = 5600(1 + 0.0765)^3

We can start by expressing the expression (2x)^2 2372x 37^2 as a multiple of 47.

47 | (2x)^2 2372x 37^2

Since 47 is a prime number, we can use the property that a multiple of a prime number is a number that can be divided by that prime number without leaving a remainder.

So, we need to find the least positive integer value of x such that (2x)^2 2372x 37^2 is divisible by 47.

We can start by assuming (2x)^2 2372x 37^2 as (2x)^2 2372x 37^2 = 47*k, where k is any integer.

We can start testing values of x starting from 1,

x=1 : (21)^2 * 23721 * 37^2 = 4 * 74 * 1369 = 47 * 2028,

x=2 : (22)^2 * 23722 * 37^2 = 16 * 148 * 1369 = 47 * 6912,

Answer:

A rhombus is a four-sided shape with all sides equal in length, and opposite angles equal. The diagonals of a rhombus bisect each other at right angles and they are equal in length.

In this case, the length of one diagonal of the rhombus is 6 times the length of the other diagonal. Let's call the length of the shorter diagonal "d", and the length of the longer diagonal "6d".

To find the perimeter of the rhombus, we can add up the lengths of all four sides. Since all sides of a rhombus are equal, we can find the perimeter by multiplying the length of one side by 4.

To find the length of one side, we can use the Pythagorean theorem to find the length of the side in terms of d, the shorter diagonal.

We know that d^2 + (3d)^2 = s^2, where s is the length of one side.

After simplifying, we get: d^2 + 9d^2 = s^2

s = √10d^2

so the perimeter is 4s = 4 √10d^2

Therefore, the perimeter of the rhombus can be represented by the expression 4* √10d^2 where d represents the length of the shorter diagonal.

Answer:

14d

Step-by-step explanation:

First the short diagonal is d, so we can mark it as d:

d

Second we have 6 times that, so 6d:

d+6d

Then we multiply it by two since a rhombus has 4 sides:

2d+12d

Then we simplify:

Given that the radius of a sphere R = √3

Let the radius of the cylinder is r and the height of the cylinder is h.

than.

r² = R² − h²/4

and Vc = πr²h

⇒ Vc = π(R² − h²/4)h

⇒ Vc = πR²h − πh³/4

dVc/dh = πR² − 3πh²/4  

(dVc/dh)R=√3 = 3π − 3πh²/4

For maximum or minimum volume,

dVc/dh = 0

⇒ 3π − 3πh²/4 = 0

⇒ 3πh²/4 = 3π

⇒ 3πh² = 3π*4

⇒ h² = 4

⇒ h=2

Also,  dVc/dh changes sign from positive to negative in the neighborhood of h=2. Hence, h=2 is a maximum point.

r² = R² − h²/4

⇒ r² = (√3)² - 2²/4

⇒ r² = 3 - 1

1. Calculate 6 factorial (6!) which is 6*5*4*3*2*1 = 720

2. Calculate 3 factorial (3!) which is 3*2*1 = 6

3. Calculate 3 factorial (3!) again which is also 6

4. Divide 6! by (3! * 3!) which is 720 / (6 * 6) = 20

When selecting a starting lineup for an indoor soccer team consisting of 6 players who must be 3 boys and 3 girls, there are 20 possible combinations. To calculate this, the coach must use the formula 6! / (3! * 3!). This formula is used to calculate the number of possible combinations when selecting a certain number of items from a set of items, where all items are unique. 6! is 6 factorial, which is calculated by multiplying the numbers from 6 down to 1 (6*5*4*3*2*1). 3! is 3 factorial, which is calculated by multiplying the numbers from 3 down to 1 (3*2*1). When 6! is divided by the product of 3! multiplied by 3!, the result is 20. This shows that the coach can select the 6 starting players in 20 different ways, as there are 6 players to choose from and they must consist of 3 boys and 3 girls. There are 7 boys and 6 girls, so each player is eligible to play each position.
