you like the store to provide more annual flowers or more perennial flowers?"
A report of the survey results stated that customers would prefer the store to provide more perennial flowers than annual flowers.

Select all statements that correctly evaluate the report.

Options:

The question is biased toward a response of wanting more annual flowers.

The question is not biased.

The question is biased toward a response of wanting more perennial flowers.

The sample is not biased.

Elza [17]

Answer:

Part 1)  -7 →  \dfrac{y^2-y+6}{-2(y+7)}  

Part 2) 3/2 → \dfrac{y^2-2y+1}{2y-3} 

Part 3) 1  → \dfrac{5y^2-6y+1}{-5(y-1)}

Part 4) -1/4 → \dfrac{y(y+5)}{4y+1}

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

we know that

To find out the non permissible replacements for y, equate the denominator of each expression equal to 0.

step 1    

we have

\dfrac{y^2-2y+1}{2y-3}

Equate (2y-3) equal to 0.

2y-3=0

solve for y

Adds 3 both sides.

2y=3

Divide both sides by 2.

y=\dfrac{3}{2}

therefore

3/2 is the non permissible replacement for y.

step 2

we have

\dfrac{y(y+5)}{4y+1}

Equate (4y+1) equal to 0.

4y+1=0

Subtract 1 both sides

4y=-1

Divide by 4 both sides

y=-\dfrac{1}{4}

therefore

-1/4 is the non permissible replacement for y.

step 3

we have

\dfrac{5y^2-6y+1}{-5(y-1)}

Equate -5(y-1) equal to 0.

-5(y-1)=0

Divide by -5 both sides

y-1=0

Adds 1 both sides

y=1

therefore

1 is the non permissible replacement for y.

step 4

we have

\dfrac{y^2-y+6}{-2(y+7)}

Equate -2(y+7) equal to 0.

-2(y+7)=0

Divide by -2 both sides

y+7=0

Subtract 7 both sides

y=-7

therefore

-7 is the non permissible replacement for y

the base of a right prism is an equilateral triangle each of whose sides measures 4cm.the altitude of the prism measures 5cm.Fin
o-na [289]

Answer:

V=34.64\ cm^3

Step-by-step explanation:

Given that,

The side of an equilateral prism = 4 cm

The altitude of the prism = 5 cm

We need to find the volume of the prism. The formula for the volume of a prism is as follows :

V=A\times h

Where

A is the area of equilateral triangle, A=\dfrac{\sqrt3}{4}a^2

So,

V=\dfrac{\sqrt3}{4}a^2\times h\\\\V=\dfrac{\sqrt3}{4}\times 4^2\times 5\\\\V=34.64\ cm^3

So, the volume of the prism is equal to 34.64\ cm^3.

One uranium atom has a mass of 3.95 x 10^-22 grams.
creativ13 [48]
Remember
(ab)/(cd)=(a/c)(b/d)
and
\frac{x^n}{x^m}=x^{n-m}

1kg=1000g=1*10^3g
hmm, I estimate, 4 of them

x=number of attoms
mass of 1 times x=1*10^3
3.95*10^-22 times x=1*10^3
divide both sides by 3.95*10^-22
x=\frac{1*10^3}{3.95*10^{-22}}= (\frac{1}{3.95}  )( \frac{10^{3}}{10^{-22}} )=0.25316*10^{25}=2.5316*10^{24}
a million has 9 zeroes
so 24 zeroes is alot that is a <span>septillion, so there are 2.5316 septillion uranium atoms in 1kg


a. 4
b. underestimate
