find the slope and equation for all please. I'm sorry to bother you all with this much questions but I truly don't understand.

Answer:

2.99

Step-by-step explanation:

To convert a number from scientific notation to standard form, consider 1.5625 x 10^4. First, focus on the exponential number, which is 10^4. Multiply the base number, which is 10, by itself the number of times indicated by the exponent, which is four. You would do that like this:

10 x 10 x 10 x 10 = 10, 000

Plug the product -- which is 10,000 -- into the original equation to get this:

1.5625 x 10,000 = 15, 625

Therefore, the standard form of this number is 15,625.

For a number in expanded form, convert the number, using basic addition. For example, consider the expanded number 10,000 + 2000 + 100 + 10 + 9. Add up these numbers to get the standard form. Your equation would look like this:

10,000 + 2,000 + 100 + 10 + 9 = 12,119

Therefore, the standard form of the number is 12,119.

A. The total outcomes would simply be the product of the number of sides of the two dice, that is:

Total different outcomes = 6 * 6

Total different outcomes = 36

B. The combinations that both dice are even are:

2 – 2, 4 – 4, 6 – 6, 2 – 4, 2 – 6, 4 – 2, 4 – 6, 6 – 2, 6 – 4

So 9 combinations for Jenny

C. The combinations that at least one die is a 4 are:

4 – 4, 4 – 1, 4 – 2, 4 – 3, 4 – 5, 4 – 6, 1 – 4, 2 – 4, 3 – 4, 5 – 4, 6 - 4

So 11 combinations for Henry

D. The probability that jenny wins would simply be the ratio of the number of combinations for Jenny over the total number of combinations, that is:

P (Jenny) = 9 / 36 = 0.25 = 25%

So there is a 25% chance that Jenny will win.

E. The probability that Henry wins would simply be the ratio of the number of combinations for Henry over the total number of combinations, that is:

P (Henry) = 11 / 36 = 0.3056 = 30.56%

So there is a 30.56% chance that Jenny will win.

F. No the game is not fair because Henry has a higher chance of winning than Jenny. For it to be fair, they should have the same probability of winning.

G. We can see that there are actually combinations in which both Jenny and Henry would win. These are:

4 – 4, 4 – 2, 4 – 6, 2 – 4, 6 – 4

So there are 5 combinations in which both of them would win.

So the chance of being tie is:

P(tie) = 5 / 36 = 0.1389 = 13.89%

Hence a 13.89% chance of getting a tie

the length of the room is  170.63 inches.

The length of the room in inches is [tex]\( 9.75 \text{ inches/foot} \times 17.5 \text{ shoe lengths} = 170.625 \text{ inches} \), or approximately \( 170.63 \) inches.[/tex]

To calculate the length of the room, we first need to determine the total distance traveled by walking across the room, heel to toe, in terms of shoe lengths, and then convert that distance into inches.

Given:

- Length of shoe = 9.75 inches

- Number of shoe lengths walked across the room = 17.5 shoe lengths

First, we find the total distance walked in inches:

[tex]\[ \text{Total distance} = \text{Length of shoe} \times \text{Number of shoe lengths} \][/tex]

[tex]\[ \text{Total distance} = 9.75 \text{ inches/shoe} \times 17.5 \text{ shoes} \][/tex]

[tex]\[ \text{Total distance} = 170.625 \text{ inches} \][/tex]

Rounded to two decimal places, the length of the room is approximately 170.63 inches.

Here’s a bit more detail on each step:

1. Convert Shoe Length to Inches: Since each shoe length is 9.75 inches, we use this conversion factor to turn the shoe lengths into inches.[tex]\( 17.5 \) shoe lengths \(\times\) \( 9.75 \) inches/shoe = \( 170.625 \) inches.[/tex]

2. Round Off: We round off the final answer to two decimal places, giving us a room length of approximately \( 170.63 \) inches. This rounding is common in measurements where precision beyond two decimal places isn't necessary.

3. Explanation Summary: By multiplying the length of the shoe by the number of shoe lengths walked across the room, we can accurately calculate the total distance traveled and thus determine the length of the room.

Answer:The third graph (left of the bottom) represents  [tex]y=\left \lceil x \right \rceil[/tex]over the domain 3≤x≤6.

Step-by-step explanation:

The Least Interger Function is represented by [tex]y=\left \lceil x \right \rceil[/tex].

The least integer function is a discontinuous function whose value at any number x is the smallest integer greater than of equal to x .It is denoted by  [tex]\left \lceil x \right \rceil[/tex].and It is also known as ceiling of x.  For example

[tex]\left \lceil3.4\right \rceil=4,\left \lceil5.6\right \rceil=6. \left \lceil4.4\right \rceil=5[/tex]

So the third graph (left of the bottom) represents  [tex]y=\left \lceil x \right \rceil[/tex]over the domain 3≤x≤6.

The total cost of tickets for Marika and her three friends to attend a school play, with each ticket costing $5.75, is calculated using the distributive property to be $23.

The question asks to find the total cost of tickets for Marika and her three friends attending a school play, with each ticket costing $5.75, and to justify the answer using the distributive property.

To calculate the total cost, we can use the formula for the total cost which is the number of tickets times the cost of one ticket. In this case, Marika is buying tickets for herself and three friends, making it a total of 4 tickets.

Therefore, using the distributive property, the total cost can be calculated as 4 tickets × $5.75 per ticket.

Using the distributive property, we can represent this as:

(4 × $5) + (4 × $0.75) = $20 + $3 = $23

Thus, the total cost of the tickets is $23.

Answer:  we will rewrite the given equation y-4 =[tex]\frac{-1}{4} (x-5)[/tex] in slope intercept form.

so, we get

y =  [tex]\frac{-1}{4} x+\frac{21}{4}[/tex]

slope = [tex]-\frac{1}{4}[/tex]   and y-intercept = [tex]\frac{21}{4}[/tex]  

now, we have to make the table of x and y

now we consider different values of x to find the value of y corresponding values of x using equation y =  [tex]\frac{-1}{4} x+\frac{21}{4}[/tex]

   X             Y

have a look at the attachment for graph.

Attached graph is having a downward-sloping line with y-intercept (0, 21/4) and a slope of -1/4. Equation: y = (-1/4)x + 21/4.

To plot the line for the equation y - 4 = -1/4(x - 5),

first rewrite it in slope-intercept form (y = mx + b), where 'm' is the slope, and 'b' is the y-intercept.

y - 4 = -1/4(x - 5)

Distribute the -1/4 on the right side:

y - 4 = (-1/4)x + 5/4

Move -4 to the right side by adding 4 to both sides of the equation:

y = (-1/4)x + 5/4 + 4

Combine constants on the right side:

y = (-1/4)x + 5/4 + 16/4

Combine fractions on the right side:

y = (-1/4)x + 21/4

Now  the equation in slope-intercept form (y = mx + b) where the slope (m) is -1/4, and the y-intercept (b) is 21/4.

To graph the line, follow these steps:

Plot the y-intercept point (0, 21/4).

Use the slope (-1/4) to find additional points. The slope -1/4 means that for every 4 units you move to the right,  go down 1 unit.

Draw a straight line passing through the points you plotted.

Here are a few more points you can use to plot the line:

When x = 0, y = 21/4.

When x = 4, y = 21/4 - 1 = 17/4.

When x = 8, y = 21/4 - 2 = 13/4.

Now, plot these points on the graph and draw a straight line passing through them.

The graph should look like a downward-sloping line.

There are 22 boys in Billy's class of 40 students, which means that 55% of the students are boys.

To find the percent of students that are boys in Billy's class, we can start by calculating the number of boys. There are 40 students in total and 18 are girls. Therefore, the number of boys is 40 students minus 18 girls, which is 22 boys. Now, to calculate the percentage of boys, we use the formula:

Percentage = (Number of boys / Total number of students) × 100%

By inserting the numbers we have:

Percentage = (22 / 40) × 100%

Percentage = 0.55 × 100%

Percentage = 55%

So, 55% of the students in Billy's class are boys.
