How many square feet of outdoor carpet will we need for this hole? HELP PLS!!!
Otrada [13]

Answer: The answer is 39 square feet.

Step-by-step explanation:

By saying square feet it's indicated that you mean the area of this irregular figure.

To do this you can break apart the shape into two pieces.

The first 11 x 3 rectangle then the 2 x 3 rectangle.

Next, you can find the area to be 33 square feet and 6 square feet. respectively, afterward, you add the areas together to find the area of the figure, which is 39 square feet.

The width of a rectangle is 5x+3, and the length of the
jok3333 [9.3K]

Answer:

<em>Answer: 1/4</em>

Step-by-step explanation:

<u>Algebraic Operations</u>

The width of a rectangle is given as W=5x+3 and the length of the rectangle is given as L=20x+12.

It's required to determine the ratio of the width to the length, that is:

\displaystyle   \frac{W}{L}=\frac{ 5x+3}{20x+12}

This fraction can be simplified if we factor the expression in the denominator. The LCF of 20x and 12 is 4, thus:

\displaystyle   \frac{W}{L}=\frac{ 5x+3}{4(5x+3)}

Now note we have the exact same expression up and down, thus simplifying:

\displaystyle   \frac{W}{L}= \frac{1}{4}

Answer: 1/4

Brianna received an overall IQ score of 117 on the Wechsler Scale. This means that Brianna has scored approximately____________
Tresset [83]

Using the normal distribution, it is found that the correct option is:

  • D. 1; 100

In a <em>normal distribution</em> with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.

In this problem:

  • The mean on the Wechsler Scale is of 100, hence \mu = 100.
  • The standard deviation is of 17, hence \sigma = 17.
  • Brianna had an score of 117, hence X = 117

Then:

Z = \frac{X - \mu}{\sigma}

Z = \frac{117 - 100}{17}

Z = 1

Hence, the option d is correct.

What is the period of the function f(x)=sin(x/3) ?
vitfil [10]
<h3>Answer: 6pi radians</h3>

(this is equivalent to 1080 degrees)

======================================

Explanation:

f(x) = sin(x/3)

is the same as

f(x) = 1*sin( (1/3)(x-0) )+0

and that is in the form

f(x) = A*sin( B(x-C) )+D

The letters A,B,C,D are explained below

A = helps find the amplitude

B = 2pi/T, where T is the period

C = determines phase shift (aka left/right shifting)

D = determines vertical shift = midline

All we care about is the value of B as that is the only thing that is connected to the period T

--------

Compare f(x) = 1*sin( (1/3)(x-0) )+0 with f(x) = A*sin( B(x-C) )+D and we see that B = 1/3, so,

B = 2pi/T

1/3 = 2pi/T

1*T = 3*2pi ... cross multiply

T = 6pi

The period is 6pi radians. This is equivalent to 1080 degrees. To convert from radians to degrees, you multiply by (180/pi).
