Jerry had k pencils. darcy and leonard then gave jerry an additional x pencils each. which expression could represent the number of pencils jerry has now?

Answers

Answer 1

Answer:

\(k\)+(\(x\)×\(x\))

Step-by-step explanation:

k is the number of pencils jerry has, and x is the number of pencils darcy and leonard gave him EACH. So you need to multiply 'x' x2 to get the total ammount of pencils they gave him, then add 'k' to know how much in total he has now.

Answers

There are no values of x that make this equation true.

Answer:

No solution!

Step-by-step explanation:

7m+11-5m-2=2m-9

2m+11-2=2m-9

2m+9=2m-9

subtract nine from both sides= 2m=2m-18

subtract two from both sides= 0=-18

A bag contains 36 red blocks, 48 green blocks, 22 yellow blocks, and 19 purple blocks. You pick one block from the bag at random. Find each theoretical probability.

P( green )

Answers

The theoretical probability of selecting a green block is 0.384 or 38.4% .

To find the theoretical probability of selecting a green block, we need to divide the number of green blocks by the total number of blocks in the bag.

Total number of blocks = 36 (red) + 48 (green) + 22 (yellow) + 19 (purple) Total number of blocks = 125

P ( green ) = Number of green blocks / Total number of blocks

P ( green ) = 48 / 125

P ( green ) = 0.384

Therefore, the theoretical probability of selecting a green block is 0.384 or 38.4% .

Answers

The linear regression equation is y ≈ -2.02x + 670.38, and the projected number of new cases for 2008 is approximately 650.

To find the linear regression equation that represents the given set of data, we can use the least squares method to determine the best-fit line. The equation will have the form y = mx + b, where m is the slope and b is the y-intercept.

First, let's calculate the mean values of x and y:

mean(x) = (0 + 1 + 2 + 3 + 4 + 5) / 6 = 15 / 6 ≈ 2.5

mean(y) = (703 + 675 + 706 + 643 + 660 + 605) / 6 = 3992 / 6 ≈ 665.33

Next, we'll calculate the values needed to determine the slope:

Σ(x - mean(x)) = (0 - 2.5) + (1 - 2.5) + (2 - 2.5) + (3 - 2.5) + (4 - 2.5) + (5 - 2.5) = 0 - 1 - 0.5 + 0.5 + 1 + 2 = 2.5

Σ(y - mean(y)) = (703 - 665.33) + (675 - 665.33) + (706 - 665.33) + (643 - 665.33) + (660 - 665.33) + (605 - 665.33) ≈ -35.33

Σ(x - \(mean(x))^2 = (0 - 2.5)^2 + (1 - 2.5)^2 + (2 - 2.5)^2 + (3 - 2.5)^2 + (4 - 2.5)^2 + (5 - 2.5)^2\)= 6.25 + 2.25 + 0.25 + 0.25 + 2.25 + 6.25 = 17.5

Now, we can calculate the slope:

m = Σ[(x - mean(x)) * (y - mean(y))] / Σ[(x - \(mean(x))^2\)] ≈ (-35.33) / 17.5 ≈ -2.02

Next, we can determine the y-intercept:

b = mean(y) - m * mean(x) ≈ 665.33 - (-2.02) * 2.5 ≈ 665.33 + 5.05 ≈ 670.38

Therefore, the linear regression equation for the given data is y ≈ -2.02x + 670.38.

To find the projected number of new cases for 2008 (10 years since 1998), we substitute x = 10 into the equation:

y ≈ -2.02(10) + 670.38 ≈ -20.2 + 670.38 ≈ 650.18

Rounding to the nearest whole number, the projected number of new cases for 2008 is approximately 650.

A soccer ball on the ground was kicked with an initial velocity of 35 ft/sec at an elevation angle of 40º. Create a set of parametric equations to model the path of the soccer ball. Approximately how far away did the soccer ball hit the ground?


19 feet

26 feet

38 feet

52 feet

Answers

Answer:

38 feet.

Step-by-step explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 35 ft/s

Angle of projection (θ) = 40º

Acceleration due to gravity (g) = 9.8 m/s²

Range (R) =?

Next, we shall convert 9.8 m/s² to ft/s². This can be obtained as follow:

0.3048 m/s² = 1 ft/s²

Therefore,

9.8 m/s² = 9.8 m/s² × 1 ft/s²/ 0.3048 m/s²

9.8 m/s² = 32.15 ft/s²

Thus, 9.8 m/s² is equivalent to 32.15 ft/s².

Finally, we shall determine how far away the soccer ball hit the ground (i.e range) as shown below:

Initial velocity (u) = 35 ft/s

Angle of projection (θ) = 40º

Acceleration due to gravity (g) = 32.15 ft/s²

Range (R) =?

R = u² × Sine 2θ / g

R = 35² × Sine (2×40) / 32.15

R = 1225 × Sine 80/ 32.15

R = 1225 × 0.9848 / 32.15

R = 37.5 ≈ 38 feet.

Thus, the soccer ball hit the ground 38 feet away.

Answers

From a class of 20 students, there are 6,840 ways to select a committee consisting of a president, vice-president, and secretary. This calculation is based on the concept of permutations, where the number of choices at each step is multiplied to find the total number of possibilities.

To determine the number of ways to select a committee consisting of a president, vice-president, and secretary from a class of 20 students, we can use the concept of permutations.

The president position can be filled by selecting one student from the 20 available. After the president is selected, the vice-president position can be filled by choosing one student from the remaining 19 students. Finally, the secretary position can be filled by selecting one student from the remaining 18 students.

The number of ways to make these selections is calculated by multiplying the number of choices at each step:

Number of ways = 20 * 19 * 18 = 6,840

Therefore, there are 6,840 ways to form the committee with a president, vice-president, and secretary from a class of 20 students.

A correlation is said to be negative between two variables when they are related in such a manner that when one variable increases, the other variable decreases and vice versa.

However, a correlation is said to be Positive when one variable increases as the other increases as well and vice versa which means they both move in the same direction.

However, in the image of the scatter plot attached, we see that it is neither positive or negative correlation as there is no clear visible relationship between the variables on the x and y axis.

An on-boardbackup server stores all data in the backend;- The user can interact with the on-board computer via a touchscreen;- When the driver is not in the vehicle, the vehicle sets up an alarm mode. Drivers get alarmsthrough their smartphones. Optionally, alarms can also be sent to the police;- The software on-board can be updated remotely by the vehicle manufacturer, with the permissionof the driver.- The operation of the vehicle will be simplified as follows: the on-board computer processes thesensor readings and makes decisions such as speed maintenance and braking operation.
