Usually when encountered with questions that relate with how large a sample should be to yield a significant result is answered by determining the sample size. The sample size is the determination of how much sample is needed for the study to reveal confidence levels of 98% or higher.

Because the population is not given in this proportion, an exact number cannot be revealed. However it might be that the sample is dependent on the nature of the study where Davis plans to exhibit.

Which composition of transformations will create a pair of similar
Romashka [77]

Answer:

A rotation, then a dilation

Step-by-step explanation:

When two triangles are congruent, the three sides and angles will be the same.

A dilation is a type of transformation that works with scale factors and enlarges or reduces a figure, to create a new figure.

Now, the composition of transformations that will create a pair of similar but not congruent triangles are - a rotation, then a dilation.

One hundred divided by twice a number is ten
Ludmilka [50]

\frac{100}{2x} = 10

Are you trying to find x, or are you only suppose to translate it?

If you are trying to find x, you first multiply 2x on both sides

100 = 10(2x)

Divide 10 on both sides

10 = 2x

Divide 2 on both sides

5 = x

HELP NEED ASAP FOR TOMORROW ITS FOR MY HOMEWORK!! ILL MARK BRAINLIEST IF RIGHT!!​
Slav-nsk [51]

Answer:

  y ≥ -x +2

Step-by-step explanation:

The solid line has a slope of -1 and a y-intercept of 2, so its equation in slope-intercept form is ...

  y = -x +2

The shaded area is above this line, and the line is part of the solution set, so we want an inequality that has "y" and the comparison symbol in this order: "y ≥" or "≤ y".

We already have an equation with "y" on the left, above, so we just need to introduce the comparison symbol:

  y ≥ -x +2

Another way to write this is ...

  x + y ≥ 2

Fractional indices pls help
bulgar [2K]

Answer:

Formula used :

  • (a^m)^n = a^(m×n)
  • a^m × a^n = a^(m+n)

27 \times  {9}^{3x} =  {3}^{k} \\  {3}^{3}  \times   { {(3}^{2}) }^{3x}  =  {3}^{k}  \\  {3}^{k}  =  {3}^{3}  \times  {3}^{(2 \times 3x)}  \\  {3}^{k}  =  {3}^{3}  \times  {3}^{6x}  \\  {3}^{k}  =  {3}^{(6x + 3)}  \\  \boxed{k = 6x + 3}

  • <u>k = (6x+3)</u> is the right answer.
