Answer:

190 cm²

Step-by-step explanation:

     Area of one regular hexagon is given. Multiply 23 *2 and it will give the area of two regular hexagons.

There are 6 rectangles. Find the area of one rectangle and multiply it by 6.

 Area of regular hexagon = 23 cm²

Area of rectangle = length * width

                             = 8 * 3

                             = 24 cm²

      Area of the regular hexagon prism = 2* area of regular hexagon + 6*area of rectangle.

                                                                 = 2*23 + 6*24

                                                                 = 46 + 144

                                                                 = 190 cm²

Considering a discrete distribution modeling the situation, it is found that:

a) The expected value of each $1 bet in roulette is of: -$0.988.

b) The interpretation is given as follows: Over time, you should expect to lose about 999 cents for every dollar you bet.

The expected value of a discrete distribution is calculated as the sum of each outcome multiplied by it's respective probability.

The total number of outcomes for the three-number bet is of:

10 x 10 x 10 = 1000.

As three numbers are taken, and for each number, there are 10 possible outcomes.

Hence the probability of winning is of:

p = 1/1000.

As there is only one correct sequence.

The probability of losing is of:

p = 1 - 1/1000 = 999/1000.

Considering a payout of $11 for a $1 bet, the distribution of earnings is presented as follows:

Hence the expected value of a $1 bet is calculated as follows:

E(X) = 11/1000 - 999/1000 = -$0.988.

Which means that you are expected to lose approximately 99 cents for every dollar that you bet.

86.135 is the IQ score separating the bottom 25% from the top 75%.

The number between a data set's lowest and median is known as the first quartile. We would utilize a Z table to locate it.

As we are looking on the left side of distribution, value of z-score will be negative.

z-score equation for x : [tex]z = \frac{x-M}{S}[/tex]

                                       [tex]x = zS+M[/tex]

where x = value we're looking for

M = Mean

   = 99.2

S = Standard deviation

  = 19.5

z = z-score

  = -0.67

Putting the value in equation,

x = -0.67*19.5 + 99.2

  = -13.065 + 99.2

  = 86.135

Hence, 86.135 is the IQ score separating the bottom 25% from the top 75%.

Answer:

a = 108°

b = 72°

c = 48°

d = 48°

Step-by-step explanation:

• ∠a and the 72° angle are on a straight line. Therefore they add up to 180°:

∠a + 72° = 180°

⇒ ∠a = 180 - 72°

⇒ ∠a = 108°

• ∠b and the 72° angle are corresponding angles (the angles make an F-shape). Therefore, they are equal:

∠b = 72°

• ∠d and the 48° angle are alternate angles (the angles make a z-shape). Therefore they are equal:

∠d = 48°

• ∠c and ∠d are vertically opposite angles. Therefore, they are equal:

∠c = ∠d

⇒ ∠c = 48°

The solution of the inequalities is x < - 3 / 2 or x > 48 / 5

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Inequality expression always have the symbols <, >, ≤ and ≥.

Therefore, let's solve the inequalities.

12x + 7 < - 11 or 5x - 8 > 40

12x + 7 < - 11

subtract 7 from both sides of the inequalities.

12x + 7 - 7 < - 11 - 7

12x < - 18

divide both sides by 12

x < - 18 / 12

x < - 3 / 2

5x - 8 > 40

add 8 to both sides of the inequalities

5x - 8 + 8 > 40 + 8

5x > 48

divide both sides by 5

x > 48  / 5

x > 48 / 5

Answer:

  B. The graph of K has a greater y-intercept

  D. The graph of J has a greater slope.

Step-by-step explanation:

Given a table for function J and an equation for function K, you want to know which has the greater slope, and which has the greater y-intercept.

The y-intercept is the value of the function when x=0. We see from the table that y=2 corresponds to x=0 for function J.

We see from the equation for function K that the constant is 8. This is the value of y when x=0.

Function K has the greater y-intercept (8 vs. 2).

The slope is the change in y-value when x increases by 1 unit. We see from the table that y=7 when x=1, so the change in y from x=0 to x=1 is 7-2 = 5. The slope of function J is 5.

The equation for function K has an x-coefficient of 3. This means a change in x of 1 unit will result in a change in y of 3 units. The slope of function K is 3.

Function J has the greater slope (5 vs. 3).

The slope is -5/3

From the question, we have

slope, m = change in y/change in x

= (-6+1)/(8-5)

=-5/3

The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

Slope of a Line :

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.

where "m" represents a line's slope.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

The y-intercept is (0, 400), which represents the amount of money the radio station originally had. The x-intercept is (8, 0), which represents the number of weeks it will take for the radio station to have $0 left.

In Mathematics, the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

Similarly, the x-intercept can be defined as the point at which the graph of any function crosses the x-coordinate and the value of "y" is equal to zero (0).

For the y-intercept, x = 0 and we have the following:

y = 400 - 50x

y = 400 - 50(0)

y = 400.

For the x-intercept, y = 0 and we have the following:

y = 400 - 50x

0 = 400 - 50x

50x = 400

x = 400/50
