According to the scatter plot below, when x = 5, the value of y is 1.

A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed. A scatter plot is a collection of dots drawn on two axes, horizontal and vertical. Scatter plots are useful in statistics because they illustrate the amount, if any, of correlation between the values of observed quantities or events (called variables). With a particular confidence interval, a scatter plot might imply several types of relationships between variables. Weight and height, for example, would be on the y-axis, whereas height would be on the x-axis. Positive (increasing), negative (falling), or null correlations exist (uncorrelated).

The following equation is m=d-10+k×i represent the total amount in account(m) in dollar.

Although the question does not specify the options, but I have specified my answer as follows:

Given:

The equation representing the total amount in the account, m, when starting with d dollars and being charged a 10$ fee.

Account Opening Charges: $10

Starting amount: $d

The total amount in the account: $m

Let us say the depositor deposits an amount $k for 'i' number of months

Banks deduct their charges from the account balance itself, hence account opening charges are deducted from the bank balance.

I have assumed an amount $k invested every month. You can remove that term as per the requirement of the question.

The total amount at a point in time = starting amount - Account Opening Charges + monthly deposit till that time

⇒m=d-10+k×i

This equation shows that the total amount in the account will be equal to the initial deposit minus the fee charged by the bank.

Therefore, the following equation is m=d-10+k×i.

The value of y if (1, y, −9) is perpendicular to vector v is  38/5.

Given vector v = 2i - 5j - 4k and vector c = 1i + yj - 9k

In the question, we are told that we need to find y if vector v and vector c are perpendicular. So, if two vectors are perpendicular their dot product is zero

So,  vector v.vector c = 0

(2i - 5j - 4k ).(i + yj - 9k)  = 0

                    2(1) - 5(y) - 4(-9) = 0

                           2 - 5y + 36 = 0

                                    5y = 38

                                      y = 38/5

Hence, the value of y is 38/5.

Answer:

a. a student who was not absent during unit should score about 98

Answer:

x = 1/a

Step-by-step explanation:

To solve 7ax + 8ax = 9ax + 6 for x, we can start by combining like terms on both sides of the equation:

7ax + 8ax = 9ax + 6

becomes

15ax = 9ax + 6

Next, we can subtract 9ax from both sides of the equation:

15ax - 9ax = 9ax + 6 - 9ax

becomes

6ax = 6

Finally, we can divide both sides of the equation by 6a to find the value of x:

6ax / 6a = 6 / 6a

becomes

x = 1/a

So, the solution for x is x = 1/a.

The time when the projectile has an instantaneous velocity of zero is a = 10 seconds.

The instantaneous velocity of a projectile at time t can be found by taking the derivative of its position function with respect to time. The velocity function is given by:

v(t) = ds(t)/dt = -32t + 320

The time at which the projectile has an instantaneous velocity of zero is when the velocity function is equal to 0. We can find this time by solving the equation:

-32t + 320 = 0

32t = 320

t = 10

Therefore, the time at which the projectile has an instantaneous velocity of zero is a = 10.

Step-by-step explanation:

In order to find the ratio of red to green sweets, we first need to find the ratio of yellow to green sweets. We know that the ratio of yellow to green is 1:5 and we also know that the ratio of red to yellow is 3:2.

We can use this information to find the ratio of red to green by cross-multiplying the ratio of red to yellow and the ratio of yellow to green.

So (3:2) x (1:5) = (3:10)

This means the ratio of red to green is 3:10.

Alternatively, we can find the ratio of red to green by using the following formula:

(red:yellow) x (yellow:green) = (red:green)

So (3:2) x (1:5) = (3:10)

The ratio of red to green is 3:10.

Answer:

Step-by-step explanation:

The ratio of red : yellow = 3:2 and yellow:green = 1:5

So, the ratio of red : yellow : green = 3:2:5

To find the ratio of red: green, we can find the ratio of red : yellow : green and then divide the red and green portions.

So, the ratio of red: green = (3/(3+2+5)) : (5/(3+2+5)) = 3/10 : 5/10 = 3:5

The surface area of a three-dimensional object is the total area of all its faces. In real-life we use the concept of surface areas of different objects when we want to wrap something, paint something, and eventually while building things to get the best possible design.

The surface area will be calculated as:-

SA = SA of cuboid + SA of cube

SA = 6 x ( 11 x 2 ) + 6 x 2

SA = 132 + 12

If a paper company needs to ship paper to a late printing business. 12 small boxes were shipped and 8 large boxes were shipped.

Using a system of equations to represent the problem.

Let x represent the number of small boxes shipped

Let  y represent the number of large boxes shipped.

We know that:

x + y = 20 (the total number of boxes shipped)

8x + 21y = 264 (the combined volume of all boxes )

Solving the first equation for y: y = 20 - x

Substituting this expression for y into the second equation:

8x + 21(20 - x) = 264

8x + 420 - 21x = 264

-13x = -156

x = 12 (small boxes)

So,

y = 20 - x

y = 20 -12

Number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL

A general rule is that the algebraic expression should take any of the following forms: addition, subtraction, multiplication, and division. Bring the variable to the left side and the other values to the right side in order to find the value of x. To determine the answer, simplify the values.

Let the number of ml of 40% sugar be x and 85% sugar used be y

System of equations is given as:

x + y = 1800mL ....... (1)

x = 1800 - y

40% × x + 85% × y = 60% × 1800mL

0.4x + 0.85y = 1080.... (2)

We substitute 1800 - y for x in (2)

0.4(1800 - y) + 0.85y = 1080

simplifying the above equation, we get

720 - 0.4y + 0.85y = 1080

- 0.4y + 0.85y = 1080 - 720

0.45y = 360

y = 360/0.45

y = 800mL

Solving for x

x = 1800 - y

substitute the value of y in the above equation, we get

x = 1800 - 800

x = 1000mL

Therefore, the number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL.
