8 0

Answer:

In a translation, ALL of the points move the same distance in the same direction. A translation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image.

Step-by-step explanation:

In addition, the corresponding segment sides of the pre-image and image are parallel.

IRINA_888 [86]

Answer:

perimeter = 6w

area = 2w^2

Step-by-step explanation:

we can use the variable w for width, and 2w for length perimeter would be width + width + length + length, or 6w

area is width x length or 2w^2

A patient requires an IV of D5W, a 5% solution of dextrose (sugar) in water. To the nearest milliliter, how much D20W, a 20% sol
solmaris [256]

Answer:

  A=300ml

Step-by-step explanation:

From the question we are told that

5% solution of dextrose sugar in water

20% solution of dextrose in

100 milliliters of distilled water water

Generally in mathematically solving we call A the amount of D20W added

Since 20% of dextrose is needed

       20 \%*100=20milliter

Total quantity after addition (100+x)

for DW5% total solution is

          5\% (100+A)= \frac{5}{100}(100+A)

          5\% (100+A) =5+0.05A

Mathematically

           5+0.05A =20

           5+0.05A =20-5

           A=\frac{15}{0.05}

           A=300ml

Therefore the required quantity A=300ml

A 12 feet tall street light is making an 18 feet shadow at the same time in nearby building is making a 72 feet shadow
Harman [31]

Answer: 48 ft

Step-by-step explanation:

Given

Height of street light h=12 ft

length of shadow x=18 ft

Shadow length of building x'=72 ft

suppose the height of the building is y

from the figure, we can write

\Rightarrow \tan p=\dfrac{h}{x}=\dfrac{12}{18}\\\\\Rightarrow \tan p=\dfrac{y}{x'}=\dfrac{12}{18}\\\\\Rightarrow y=72\times \dfrac{2}{3}=48\ ft

A researcher wishes to conduct a study of the color preferences of new car buyers. suppose that 50% of this population prefers t
djyliett [7]

To solve this question, use the Binomial probability formula.

The formula is given by

^nC_xp^x(1-p)^{n-x}

Where:

n = the number of trials

x = the sample we aim to try

p = the probability of success

In this question:

n = 16

x = 9

p = 0.5

Substituting in the equation:

\begin{gathered} ^nC_xp^x(1-p)^{n-x} \\ ^{16}C_9*0.5^9(1-0.5)^{16-9} \\  \end{gathered}

And the combination formula:

^nC_x=\frac{n!}{(n-x)!*x!}

Then:

\begin{gathered} \frac{16!}{(16-9)!*9!}*0.5^9(1-0.5)^{16-9} \\ \frac{16!}{7!*9!}*0.5^9*0.5^7 \\ 11440*0.00195*0.0078 \\ =0.1746 \end{gathered}

Answer: The probability is 0.1746.
