There are 720 different possibilities for selecting the executive board from a Student Council with 10 members. An answer is option (B) 720.

A permutation is to select an object then arrange it and it cares about the orders while a Combination is about only selecting an object without caring about the orders.

The number of ways to select the executive board is the number of permutations of 10 items taken 3 at a time.

That is:

P(10, 3) = 10!/(10-3)! = 10x9x8 = 720

Therefore, there are 720 different possibilities for selecting the executive board from a Student Council with 10 members. An answer is option (B) 720.

Answer:

m<BFC= 64°; m<AFB= 116°

Step-by-step explanation:

Using the Vertical Angle Theorem, in which "the opposing angles of two intersecting lines must be congruent, or identical in value"

m<AFE is congruent to m<BFC, therefore m<BFC is 64°

You can also use the straight angle theorem where BE is a straight line, and is therefore 180°. so subtracting 180° from 64° will result in m<AFB being 116°, you second answer. You can take it a step further without using the vertical angle theorem to get our first answer by using the same rules for the straight angle theorem again, knowing that AC is a straight line and that m<AFB is 116°, subtract 180° by 116° to get m<BFC, 64°.

The sets A and B define a function, while the set C does not.

To determine whether a set defines a function, we need to check if there is one and only one output for each input. In other words, there should not be two different outputs for the same input.

\( A=\{(a, d),(c, d),(e, f),(b, f)\} \)

In this set, there are no repeated inputs, so it does define a function.

\( B=\{(1,3),(2,4),(5,6),(3,4)\} \)

In this set, there are also no repeated inputs, so it does define a function.

\( C=\{(1, a),(2, b),(3, c),(2, a),(4, d),(5, c)\} \)

In this set, there are two different outputs for the input 2 (b and a), so it does not define a function.

Therefore, the sets A and B define a function, while the set C does not.

Answer: 3.31662479036.

The  (√12 - √3)² = 6 according to the provided assertion.

Why do you use the word "binomial"?

A Binomial is a name for an algebraic equation with only two elements. It is a polynomial with two terms. It is also referred to as the total or difference of two or more binomials. It is a polynomial's most basic shape.

To expand and simplify the expression (√12 - √3)², we can use the formula for the square of a binomial:

(a - b)² = a²  + b² - 2ab

In this case, a = √12 and b = √3, so we have:

(√12 - √3)² = (√12)² - 2(√12)(√3) + (√3)²

To simplifying, we have:

(√12 - √3)² = 12 - 2√36 + 3

Since √36 = 6, we can simplify further:

(√12 - √3)² = 12 - 2(6) + 3 = 6

Therefore, the expanded and simplified equation (√12 - √3)² = 6.

If Kenneth has 5/8 feet of lumber, then he need 83/40 feet of lumber to make the shelf.

First we convert the length of lumber in improper fraction form,

So, we convert 2(7/10) feet to an improper fraction,

⇒ 2(7/10) = (2×10 + 7)/10 = 27/10,

To find the length of lumber required we need to subtract the amount of lumber Kenneth has from the total length required,

Kenneth has a total of 5/8 feet of lumber,

Length of lumber required is = 27/10 - 5/8,

Taking LCM of 10 and 8 as 40 , and simplifying further,

We get,

14 men / 2 men = 7 men who like playing golf for every man who likes running

There are 6 women who like playing golf and 18 women who like running, so the ratio of women who like playing golf to women who like running is:

6 women / 18 women = 1/3 or 0.333 women who like playing golf for every woman who likes running

Therefore, the correct statement is:

C. For every woman who likes running, 7 women like playing golf.

To find the probability that four out of 25 randomly selected students are asthmatic, we can use the binomial probability formula:

P(X = x) = (n choose x) * p^x * (1 - p)^(n - x)Where n is the number of trials (students), x is the number of successes (asthmatic students), and p is the probability of success (8.8% or 0.088).

Plugging in the given values, we get:
P(X = 4) = (25 choose 4) * 0.088^4 * (1 - 0.088)^(25 - 4) = 12,650 * 0.00005993 * 0.35178 = 0.0266

Answer: Since lines l and m are parallel, we can use the fact that corresponding angles are congruent. Therefore:

m∠1 = m∠6 (corresponding angles)

m∠6 + m∠2 = 180° (supplementary angles, as angles 6 and 2 form a straight line)

m∠2 = m∠7 (corresponding angles)

m∠3 = m∠7 (alternate interior angles)

m∠1 + m∠4 = 180° (supplementary angles, as angles 1 and 4 form a straight line)

m∠3 + m∠4 = 180° (supplementary angles, as angles 3 and 4 form a straight line)

We know that m∠1 = 63°, so we can use the equations above to find m∠6 and m∠7:

m∠1 = m∠6, so m∠6 = 63°.

m∠6 + m∠2 = 180°, so m∠2 = 180° - m∠6 = 180° - 63° = 117°.

m∠2 = m∠7, so m∠7 = 117°.

m∠3 = m∠7, so m∠3 = 117°.

m∠1 + m∠4 = 180°, so m∠4 = 180° - m∠1 = 180° - 63° = 117°.

m∠3 + m∠4 = 180°, so m∠3 + 117° = 180°, which means m∠3 = 63°.

Therefore, the measures of the angles are:

m∠1 = 63°

m∠2 = 117°

m∠3 = 63°

m∠4 = 117°

m∠6 = 63°

m∠7 = 117°

Answer:

Step-by-step explanation:

Part A: The function f(x) is an exponential function.

Part B: As x increases by 1, the value of f(x) increases by a factor of 6.

It is an exponential function because the function is of the form f(x) = a^(x-1), where a is a constant. We can see that when x increases by 1, the exponent in the function increases by 1 as well. So we have:

f(x+1) = a^x * a

f(x) = a^(x-1)

Therefore, the ratio of f(x+1) to f(x) is:

f(x+1)/f(x) = (a^x * a) / (a^(x-1)) = a

This means that as x increases by 1, the value of f(x) increases by a factor of a, which in this case is 6. Therefore, statement B supports the correct answer from Part A.

At Bank A, the interest rate was 8% (7.94% rounded to the nearest fourth of a percent). At Bank B, the interest rate was 5% (5.09% rounded to one decimal place).

To find the interest rate at each bank, we can use the formula for compound interest and the formula for continuously compounded interest.
For Bank A, the formula for compound interest is A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
Plugging in the values we have, we get:
51010.5 = 1000(1 + r/4)^(4*5)
Solving for r, we get:
r = 4[(51010.5/1000)^(1/20) - 1]
r = 0.1999
So the interest rate at Bank A is about 19.99%, or 20% when rounded to the nearest fourth of a percent.
For Bank B, the formula for continuously compounded interest is A = Pe^(rt), where A is the final amount, P is the principal, r is the interest rate, and t is the number of years.
Plugging in the values we have, we get:
5192.20 = 5500e^(r*5)
Solving for r, we get:
r = (1/5)ln(5192.20/5500)
r = -0.0118
So the interest rate at Bank B is about -1.18%, or -1.2% when rounded to the nearest fourth of a percent.
Therefore, the interest rate at Bank A is about 20% and the interest rate at Bank B is about -1.2%.
