The expected number of left-handed people in the sample= 45

The number of people selected at random= 450

The percentage of people that are left-handed =10%

Therefore, the number of people that are left-handed,

= 10/100 * 450

Answer:

  x = 17/14 = 1 3/14

Step-by-step explanation:

You want the value of x in 8(x-3)+7=2x(4-7).

It often works well to simplify the equation first.

  8x -24 +7 = 2x(-3) . . . . . use the distributive property

  14x -17 = 0 . . . . . . . . add 6x

  x -17/14 = 0 . . . . . . divide by 14

  x = 17/14 = 1 3/14

The previous price given the percentage decrease is 400.

It follows from the task content that the previous price of the commodity is required;

let, x = previous price

New price = 340

Percentage decrease = 15%

Hence, it follows from the given information that;

340 = x - (15% × x)

340 = x - (0.15x)

340 = 0.85x

x = 340/0.85

x = 400

Therefore, the previous price given the percentage decrease is 400.

Graph from equations can easily be made using slope-intercept form, for y=10x, y=5x+10 and y=15x-200 which are attached in image also.

Putting each equation into slope-intercept form, which is y=mx+b, where m is the slope and b is the y-intercept, is the first step towards accurately graphing these equations. Once the equations are in this format, they are simple to plot on a graph.

The slope and y-intercept of equation #1:

y=10x, are 10 and 0, respectively. This indicates that the line has a sharp upward slope and passes through the origin (0,0). We can start at the origin and then go up 10 units for every 1 unit to the right to graph this equation. The resulting graph will be a straight line with an increasing slope that passes through the origin.

The slope and y-intercept of equation #2:

y=5x+100, are 5 and 100, respectively. This indicates that the line has a less acute upward slope than equation #1 and goes through the point (0,100). Starting at the y-intercept, we can move up 5 units for every 1 unit to the right to graph this equation. A straight line that passes through the point (0,100) and has a less acute upward slope than equation #1 will be the final graph.

The slope and y-intercept of equation #3:

y=15x-200 and respectively, 15 and -200. This indicates that the line has a greater upward slope than equation #2 and goes through the point (0,-200). Starting at the y-intercept, we can advance up 15 units for every unit to the right in order to graph this equation. The graph that results has a stronger upward slope than equation #2 and passes past the point (0,-200).

Step one:

given data

the cost of the laptop= $800

initial payment= $200

monthly payment = $60

let the number of months be x

the expression for the situation is the function for the equation of line

y=mx+c

Step two:

the expression for the situation is

800=200+60x

solve for x

800-200=60x

400=60x

divide both sides by 60

x=400/60

x=6.7

The parametric equations for the line segment from (-3, 18, 31) to (11, -4, 48) can be expressed as follows:

x(t) = -3 + (11 - (-3))t

y(t) = 18 + (-4 - 18)t

z(t) = 31 + (48 - 31)t

In these equations, t represents the parameter that varies along the line segment. By plugging in different values of t, we can obtain corresponding points on the line segment.

The x(t) equation represents the x-coordinate of the line segment, where -3 is the initial x-coordinate and (11 - (-3)) represents the change in the x-coordinate over the segment. By multiplying this change by t, we can determine the specific x-coordinate at any point along the line segment.

Similarly, the y(t) equation represents the y-coordinate, where 18 is the initial y-coordinate and (-4 - 18) represents the change in the y-coordinate. Multiplying this change by t gives us the y-coordinate at any point.

Lastly, the z(t) equation represents the z-coordinate, where 31 is the initial z-coordinate and (48 - 31) represents the change in the z-coordinate. Multiplying this change by t allows us to determine the z-coordinate at any point along the line segment.

By using these parametric equations, we can generate points that lie on the line segment connecting the given two points and describe the entire line segment in three-dimensional space.

Answer:

x = 7 and y = 17

Step-by-step explanation:

16x + 9x + 5 = 180 cuz they are supplementary

25x = 175

x = 7

We also know that 16x + 4y = 180

so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17

The conclusion of conjuncture that robyn will be 6 ft , 2 in. tall when she has completed 22 years age is not valid. So, option(b) is right one.

We have some statement or conjectures. We have to determine the final or produced conjecture is valid or not. According to statement, In fast five years,

The growth rate of Robyn's height = 2 in. per year

But for next five years the growth rate may or may not be remain same, i.e, 2 in. every year. Now, Age of Robyn = 15 years and Height of Robyn = 5 feet, 4 in. = 64 inches ( from conversion factor, 1 ft = 16 inches)

The final statement is that she will be 6 ft , 2 in. that is 74 inches tall when she's 22 years old. After 7 years from now, the increase in her height = 2 × 7 = 14 inches

and new height = 64 inches + 14 inches

= 78 in. = 6 feet, 6 inch.

So, this is not valid conjecture.
