The sample space for rolling a fair seven-sided die is the one on the first option.

S= {1, 2, 3, 4, 5, 6, 7}

For any experiments with some given outputs, the sample space is the set of the possible outputs.

For example, for a coin with two outputs (heads and tails) the sample space is just {head, tails}

Particularly, for a fair seven-sided die we have 7 possible outputs, which are all the whole numbers from 1 to 7, then the sample space for that die is:

S= {1, 2, 3, 4, 5, 6, 7}

So the correct optionis the first one.

Answer:

x = 4  rounded to the nearest whole number (actually 4.0801)

Step-by-step explanation:

The triangle formed by the sides of length 0.9x, 2.8x and 12 form a right triangle with the side of length 12 as they hypotenuse

By the Pythagorean theorem

c² = a² + b² where c = hypotenuse, a and b being the other two sides

Plugging in values we get

12² = (0.9x)² + (2.8x)²

144 = 0.81x² + 7.84x² = 8.65x²

Switching sides:

8.65x²= 144

x² = 144/8.65 = 16.6473

x = √16.6473= 4.0801

Rounded to the nearest integer, x = 4

The converse of the statement  x⇒y is y⇒ x, So correct option is A.

A converse statement is a type of logical statement in mathematics that takes a conditional statement and switches its hypothesis and conclusion. The converse of a statement is formed by interchanging the hypothesis and conclusion of the original statement. In other words, the converse of a statement takes the form "If B, then A," whereas the original statement takes the form "If A, then B."

For example, consider the statement "If it rains, then the roads are wet." The converse of this statement would be "If the roads are wet, then it rains." It's important to note that the converse of a statement may not always be true, even if the original statement is true.

In mathematical proofs, a converse statement can sometimes be used to support a proof, but it is not always reliable on its own. This is because the converse of a statement only establishes a logical relationship between two statements if both the original statement and its converse are true. If either the original statement or its converse is false, then the converse cannot be used to make a conclusion about the relationship between the two statements.

In conclusion, a converse statement is a type of logical statement that takes a conditional statement and switches its hypothesis and conclusion. It's important to note that the converse of a statement may not always be true, and its validity depends on the validity of both the original statement and its converse.

Answer:

Step-by-step explanation:

The expression √6 (4√3 + 2√6)​ is multiplied and simplified to get 12√2 + 12

From the problem we have the expression

√6 (4√3 + 2√6)​

The problem is solved multiplying first

=√6 (4√3 + 2√6)​

= √6 * 4√3 + √6 * 2√6

Using the distributive property, we can simplify each term:

√6 * 4√3 = 4 * √(6 * 3) = 4 * √18 = 4 * 3√2

√6 * 2√6 = 2 * √(6 * 6) = 2 * √36 = 2 * 6

Adding the two simplified terms, we get:

4 * 3√2 + 2 * 6 = 12√2 + 12

So, the expression √6 (4√3 + 2√6) simplified to 12√2 + 12.

Answer:

Let x be the price per ream in dollars. Then, the manufacturer's profit per ream sold is (x - $2).

The manufacturer estimates that for each $1 increase in the price, 400 fewer reams will be sold each month. Thus, the number of reams sold can be expressed as 4000 - 400(x - $5) reams per month.

The manufacturer's total monthly profit is given by the product of the number of reams sold and the profit per ream, so it can be expressed as:

P(x) = (4000 - 400(x - $5)) * (x - $2)

So the monthly profit as a function of the price per ream is:

P(x) = 4000x - 8000 - 400x^2 + 2000x + 8000

This is a quadratic equation and its maximum value can be found using techniques from algebra or calculus.

We can write the complete table as -

-2                                                                 - 5 x 4 + 14 x - 2 + 3 = - 45

-0                                                                 - 5 x 0 + 14 x 0 + 3 = 3

1                                                                   - 5 x 1 + 14 x 1 + 3 = 12

The value of x is 30°

Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.

(5w+20)° + 3w° = 180° (sum of angles on a straight line is 180° )

5w +20 + 3w = 180

8w + 20 = 180

8w = 180 - 20

8w = 160

w = 160/8

w = 20°

3w° + 4x°  = 180° (sum of angles on a straight line is 180° )

3w + 4x  = 180

Put w = 20 and solve for x:

3(20) + 4x  = 180

60 + 4x  = 180

4x = 180 - 60

4x = 120

x = 120/4

x = 30°

The maximum height attained by the ball is 311 feet and it takes approximately 1.5 seconds to get there

To find the time at which the ball reaches its maximum height, we need to find when its velocity is equal to 0. We can find the velocity at any time by taking the derivative of the height function, f(x). So, f'(x) = -32x + 48. Setting f'(x) = 0, we get:

f'(x) = -32x + 48 = 0

32x = 48

x = 1.5

So it takes 1.5 seconds for the ball to reach its maximum height.

b. To find the maximum height, we substitute t = 1.5 back into the height function, f(x):

f(1.5) = -16(1.5)^2 + 48(1.5) + 275

f(1.5) = -16(2.25) + 72 + 275

f(1.5) = -36 + 72 + 275

f(1.5) = 36 + 275

f(1.5) = 311 ft

Therefore, the maximum height the ball reaches is 311 feet.

the maximum number of caps she can order is 162.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, Laura is the fundraising manager for a local charity she is ordering caps for an upcoming charity walk.

Let "x" be the number of caps she ordered.

Since, manufacturing cost for a cap = $6

shipping charges for the lot = $25

Thus,

Total price she paid for x caps = 6*x + 25

Since she had only 1000$

So,

6x + 25 ≤ 1000

6x ≤ 975

x ≤ 975/6

x ≤ 162.5

therefore, the maximum number of caps she can order is 162.
