Find each percent of change. Round to the nearest whole percent if necessary. State whether the percent of change is an increase

Alex787 [66]

So first we see if increase or decrease
180<210
it is increase

then we assume that
percent change
find how much change took place
210-180=30
30/180=x% change
percent means parts out ofo 100s so x%=x/100
30/180=x/100
multiply both sides by 100
3000/180=x
16.66666=x
answe ris 16.6%

Hey ! Can anyone help me with this question please ? Thank you

Semenov [28]

Answer:

let y be 126°[vertically opposite angle]

x°+y°=180°[co-interior angle]

x+126°=180°

x=180°-126°

so,x=54°

Use the two way table below to answer the question given.

GaryK [48]

Answer:

Not independent

Step-by-step explanation:

Given

See attachment for two way table

Required

Are male and favor independent?

From the table, we have:

$Male = 20+15+17$

$Male = 52$

$Favor = 20 + 18$

$Favor = 38$

$Total = 20+15+17+18+12+7$

$Total = 89$

Calculate P(Male)

$P(Male) = \frac{Male}{Total}$

$P(Male) = \frac{52}{89}$

Calculate P(Favor)

$P(Favor) = \frac{Favor}{Total}$

$P(Favor) = \frac{38}{89}$

Calculate P(Male and Favor)

$P(Male\ and\ Favor) = \frac{Male\ and\ Favor}{Total}$

$P(Male\ and\ Favor) = \frac{20}{89}$

$P(Male\ and\ Favor) = 0.2247$

The events are independent is:

$P(Male\ and\ Favor) =P(Male) * P(Favor)$

So, we have:

$P(Male\ and\ Favor) =\frac{52}{89} * \frac{38}{89}$

$P(Male\ and\ Favor) =\frac{52*38}{89*89}$

$P(Male\ and\ Favor) =\frac{1976}{7921}$

$P(Male\ and\ Favor) =0.2495$

By comparison:

$P(Male\ and\ Favor) =0.2495$ and $P(Male\ and\ Favor) = 0.2247$ are not equal

<em>Hence, the events are not independent</em>
