Firdavs [7]3 years ago
6 0

Answer:

It’s equivalent.

Step-by-step explanation:

Collect like terms: 4x+12 = 4(3+x)

Expand brackets: 4x+12 = 12+4x

Rearrange: 4x+12 = 4x+12

Write the standard form of the line that contains a slope of 2/3 and passes through the point (1, 1). Include your work in your
Aneli [31]
In this item, we are given with the slope, m = 2/3 and intercept of (1,1). The equation of the line that contains these properties is,

    y - y₁ = m(x - x₁)

Substituting the known values,

   y - 1 = (2/3)(x - 1)

Simplifying,

    3y - 3 = 2x - 2

Further simplifying,

<em>  2x - 3y = -1</em>

64/72 in simplest form
Stells [14]
64=2^6, 72=2^3*3^2

gcd (64,72)=8
Therefore 64/8 =8
72/8=9
gcd (8,9) =1
8,9 are relatively prime.
Thus, 64/72=8/9

(1.2)Consider the diagram below. Identify a point.
Fynjy0 [20]

Option B is correct. <em>Point F</em><em> is the </em><em>only point </em><em>according to the option given</em>

A point is defined as an exact location with no size, length, or even width.

From the diagram shown, we have points, plane, and line segments.

  • The only plane that we have is plane R making option C incorrect.

  • A line is defined as a straight figure connected by two points. From the diagram, the line segments that we have are AN, BN, and AB falsifying options A and D.

The points are C, D, E, and F. Hence the correct option is B.<em> Point F</em><em> is the </em><em>only point </em><em>according to the option given</em>

A sample of 50 observations is taken from an infinite population. The sampling distribution of : a.is approximately normal becau
Korvikt [17]

Answer:

a.is approximately normal because of the central limit theorem.

Step-by-step explanation:

The central limit theorem states that if we have a population with mean μ and standard deviation σ and we take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed.

For any distribution if the number of samples n ≥ 30, the sample distribution will be approximately normal.

Since in our question, the sample of observations is 50, n = 50.

Since 50 > 30, then <u>our sample distribution will be approximately normal because of the central limit theorem.</u>

So, a is the answer.
