what is the surface area, in square inches, of the rectangular prism formed by folding the next below?

Answer:

Step-by-step explanation:

If the first cube lands on a 4, then the second cube must land on 4 5 or 6.

It cannot land on 5 because that would make it the sum odd. (4 + 5 = 9)

So that leaves 4 and 6. You cannot use 2 because 4 + 2 = 6. The sum must be greater than 6.

So we are left with 2 results. The second cube should be 4 or 6

The results are 4 and 4

and 4 and 6

The results of throwing 2 dice are 36 ways in all. Only 2 combinations work.

2/36 = 1/18

I'm not sure that this is correct but it is the way done by the person writing the question.

B. Kevin

Step-by-step explanation:

First off, great job on answering the rest! Kevin worked the fastest because he has the lowest time spent per flyer. This means that for every flyer he spent time working on, he would complete it faster than Bill or Dante. This can also be estimated from the table given because although kevin only made 6, he spent only 24 minutes while Bill spent 56 minutes and only made 8. The smaller minutes spent in comparison to the amount of flyers made shows that Kevin is the fastest.

Step-by-step explanation:

The probability of picking a 3 is 1/4.

The probability of picking up a 1 the second time will be 1/3 since there will only be 3 cards left after the first time picking up the 3.

So 1/4 x 1/3 = 1/12

Step-by-step explanation:

the team started off with $1386.50

subtract $1137.50 for the rented bus

[tex]1386.50 - 1137.50 = 249[/tex]

the team has $249 left for the meals and a meal costs $20.75 for each player.

249 ÷ 20.75 = 12

the team can bring 12 players to the tournament.

Answer:

the point 6,5 is the maximum Value of c out of the other points

An equation is formed of two equal expressions. The value of x that can satisfy this equation is 1.875.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The model represents the equation as given below,

[tex](6 \times -x)+(6 \times 1) = (2 \times x) + (9 \times -1)\\\\-6x+6=2x-9\\[/tex]

The value of x that can satisfy this equation can be written as,

[tex]-6x+6=2x-9\\\\-6x-2x=-9-6\\\\-8x = -15\\\\8x=15\\\\x = \dfrac{15}{8} = 1.875[/tex]

Hence, the value of x that can satisfy this equation is 1.875.

Answer:

3.2%

Step-by-step explanation:

I = prt

I = $13,536 - $12,000 = $1,536

1,536 = 12,000 × r × 4

r = 1,536/(12,000 × 4)

r = 0.032 = 3.2%

Answer:

Below!

Step-by-step explanation:

1. Determining the y-intercept of the line:

The provided equation is in point slope form. To determine the slope and the y-intercept, we need to convert the equation to slope intercept form. Once it is converted to slope intercept form, the constant will be the y-intercept of the line. Start out by simplifying the distributive property on the R.H.S.

[tex]\implies y + 3 = 2 (x + 4)[/tex]

[tex]\implies y + 3 = (2x + 8)[/tex]

Now, open the parenthesis on the R.H.S

[tex]\implies y + 3 = 2x + 8[/tex]

If we take a look at the formula of slope intercept form (y = mx + b), we can see that "y" is isolated on the L.H.S. Thus, we need to subtract 3 both sides to isolate the y-variable.

[tex]\implies y + 3 - 3 = 2x + 8 - 3[/tex]

[tex]\implies y = 2x + 5[/tex]

We can see that the only constant in the equation is 5.

Therefore, 5 is the y-intercept.

2. Determining the slope of the line:

To determine the slope of the line, let's compare the formula with the equation obtained.

[tex]\implies (y = 2x + 5) \ = \ (y = mx + b)[/tex]

Thus, we obtain the following:

Thus, 2 is the slope of the line.

3. Plotting the line on the coordinate plane:

To graph the line on a coordinate plane, plot the y-intercept on the graph. The y-intercept is ALWAYS plotted on the y-axis.

Thus, the y-intercept plotted on graph is (0, 5).

Furthermore, plot a second point on the graph to draw a straight line through those points.

Determining the second point of the line:

If the slope of the line is 2, it means that the run (x) is 1 and the rise (y) is 2. Thus, we can add 1 to the x-coordinate of the y-intercept and 2 to the y-coordinate of the y-intercept.

Then, plot these points on the coordinate plane. Keep in mind that plot the x coordinate first, then the y-coordinate next. Once the coordinates are plotted, draw a line from the x-coordinate and another line from the y-coordinate. Finally, use your ruler and draw a line that passes through those two points. Your obtained graph is the graph of the line.

add up 8 7 11 6. 12 and then multiply that answer by 11. how to do it..... 8+7+11+6+12 =? 11×?=

Answer:

4 weekdays and 2 weekends.

Step-by-step explanation:

6 days.

x = weekdays

y = weekends

7x = amount with weekdays

12y = amount with weekends

7x + 12y = 52, total

x + y = 6, amount of days

solve double variable equation

x = 6 - y, plug in to 1st equation

7(6 - y) + 12y = 52

42 - 7y + 12y = 52

5y = 10

y = 2 weekends

2 + x = 6

x = 4 weekdays

Answer:

Step-by-step explanation:

There is no pair of real numbers that have a total of -4 and a product of 5. The complex numbers (-2+i) and (-2-i) will meet your requirements.

__

If the numbers of interest are 'a' and 'b', they will be zeros of the quadratic whose factored form is ...

  (x -a)(x -b) = 0

Expanding that, we find an opportunity to use the given sum and product numbers:

  x² -(a+b)x +ab = 0

  x² -(-4)x +5 = 0

Rewriting this in vertex form gives ...

  (x² +4x +4) +1 = 0

  (x +2)² +1 = 0

We can find the values of x by subtracting 1 and taking the square root.

  (x +2)² = -1

  x +2 = ±√(-1) = ±i

  x = -2±i

The two numbers of interest are -2+i and -2-i.

The difference of the sample means is statistically significant because it falls outside the 5% significance level.

The formula for a 95% confidence interval for the difference between two population means is:

(sample mean difference) ± (critical value) x (standard error of the mean difference)

Assuming a two-tailed test and a sample size greater than 30, the critical value is approximately 1.96. The standard error of the mean difference is calculated by dividing the standard deviation of the sample mean differences by the square root of the sample size.

So, the 95% confidence interval is:

1.74 ± 1.96 x (0.69/√n)

Assuming that the sample size is not given, we cannot calculate the exact confidence interval. However, we can say that the confidence interval will be of the form:

1.74 ± (some number)

Therefore, the 95% confidence interval is a range of values that contains the true population mean difference with 95% confidence.

Blank 1: -1.26

Blank 2: 3.44

In order to determine whether the difference is statistically significant, we need to compare the confidence interval to the null hypothesis of no difference. If the confidence interval does not contain the null hypothesis value, then we can reject the null hypothesis and conclude that the difference is statistically significant at the chosen significance level (5% in this case).

The null hypothesis in this case is that there is no difference between the population means. Since we are assuming this for the purpose of constructing the confidence interval, the null hypothesis value is 0.

The confidence interval in Part A does not contain the null hypothesis value of 0, since it ranges from -1.26 to 3.44. Therefore, we can reject the null hypothesis and conclude that the difference is statistically significant at the 5% significance level.

So, the correct answer is that the difference of the sample means is statistically significant because it falls outside the 5% significance level.
