The equation of the line in standard form is -1/2x + y = 1 or y = 1/2x + 1 in slope-intercept form.

(note: none of the option given is correct).

In standard form, the equation of a line can be expressed as Ax + By = C, where x and y are coordinate of a point on the line, A, B, and C are integers.

This equation can be rewritten in slope-intercept form as y = mx + b, where b is the y-intercept and m is the slope.

Given:

Substitute m = 1/2, x = 4, and y = 3 into y = mx + b to find b:

3 = 1/2(4) + b

3 = 2 + b

3 - 2 = b

1 = b

b = 1

Write the equation by substituting b = 1 and m = 1/2 into y = mx + b:

y = 1/2x + 1

Rewrite in standard form

- 1/2x + y = 1

Thus, none of the options is correct, The equation is: y = 1/2x + 1 in slope-intercept form or - 1/2x + y = 1 in standard form.

Answer:

Step-by-step explanation:

The perimeter of the given polygon rounded to the nearest tenth is; 24.7

What is the perimeter of the Polygon?

The given polygon as we can see has 10 sides.

Now, when we draw a line from the center to the next vertex to the left of the one currently having a line, we will see that the angle can be calculated as; 360/10 = 36° because sum of exterior angles of a polygon sums up to 360°.

Thus, the other two angles will be; (180 - 36)/2 = 72° each

Using sine rule, we can find the length of a side of the polygon as;

x/sin 36 = 4/sin 72

x = (4 * sin 36)/sin 72

x = 2.472

Thus, perimeter = 2.472 * 10 = 24.72 ≈ 24.7

The most typical or average value among a group of numbers is called the mean. It is a statistical measure of a probability distribution's central tendency along the median and mode. It also goes by the name "anticipated value."

Steel rods are produced by a firm. The lengths of the steel rods have a mean of 140.9 cm and a standard deviation of 1 cm, and they are regularly distributed. 22 steel rods are packaged together for shipping. determine the likelihood that the average length of a bundle of steel rods chosen at random is less than 140.7 cm.

mean is N (M) (109,1.6)

Looking for P(M 108.7) to P(z ???) conversion utilizing N(0,1) z-statistic transformation

P(z [M - population mean]/[SD/square root(sample size)]) = P(z [108.7-109)/[1.6/sqrt(27)] = P(z -0.974] = 0.165.

Answer:

y=65/100x+2.5

Step-by-step explanation:

The multiplication expression is given as L × w

The expression is given as N = r+ g + w + b

The final product of the expression is 200 boxes

Note that the formula determining the area of a rectangle is expressed as;

Area = lw

Where;

The area of the figure can be calculated by multiplying the length and the width and then addition of the number of boxes.

This is given as;

10( 4 + 5 + 4 + 7)

Also

L × w =  r + g + w + b

The expression L×w is a multiplication expression.

Total number of boxes vertically is the length = 20

Total number of boxes horizontally is the width = 10

Total area = L×w = 20 × 10 = 200

Then,

N= r + g + w + b

We have;

L×B =  3r + w

Hence, a multiplication expression is expression having variables that are multiplied.

g( x ) = 2x² + 12x + 22 is the standard form of the the function g( x ) = 2( x + 3 )² + 4.

Polynomials in standard forms are written in a way that arrange the terms in descending order.

Given the data in the question.

g( x ) = 2( x + 3 )² + 4

First, we expand; ( x + 3 )² → ( x + 3 )( x + 3 )

g( x ) = 2( ( x + 3 )( x + 3 ) ) + 4

Using FOIL Method

g( x ) = 2( x² + 3x + 3x + 9 ) + 4

g( x ) = 2( x² + 6x + 9 ) + 4

Apply distributive property

g( x ) = 2( x² + 6x + 9 ) + 4

g( x ) = ( 2x² + 12x + 18 ) + 4

Add 18 and 4

g( x ) = 2x² + 12x + 18 + 4

g( x ) = 2x² + 12x + 22

Therefore, the function in standard form is g( x ) = 2x² + 12x + 22

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

Since the ages of students at a university are normally distributed with a mean of 21, the percentage of the student body that is at least 21 years old is: 50%.

A normal distribution is also referred to as the Gaussian distribution and it can be defined as a probability distribution that is continuous and symmetrical on both sides of the mean, which indicate that all data near the mean have a higher frequency than the data that are far from the mean.

For all normal distributions, the mean is always located at the center with 50 percent (50%) or 0.5 of the distribution to either side, which is right or left of the distribution.

In this context, the percentage of student body that is at least 21 years old is represented by the percentage to the left of the normal distribution, which is 50 percent (50%):

P(x ≤ 21) = 50%

P(x ≤ 21) = 50/100

P(x ≤ 21) = 0.5.

The volume of the cube with the shortest possible side lengths is 216 cubic inches.

If a steel sphere with a 3-inch radius is made by removing metal from the corners of a cube that has the shortest possible side lengths, then the side lengths of the cube must be equal to the diameter of the sphere.

side length of cube = diameter of sphere

side length of cube = 2 x radius of sphere

side length of cube = 2 x 3 inches

side length of cube = 6 inches
