Answer:

let the breadth of room be 'x'm

so the lenghth of room is 'x+8'm

Given

Area of room=48m²

i.e length ×breadth =48m²

or,(x+8)x=48

or,x²+8x-48=0

or,x²+12x-4x-48=0

or,x(x+12)-4(x+12)=0

or,(x+12)(x-4)=0

Either x+12=0

or,x=-12(which is not possible)

Or,x-4=0

or,x=4

Thus,breadth is 4m.

length=x+8=4+8=12m

The dimensions of room are 8m and 12m respectively.

The number of adult Americans from a random sample of n adults who support a bill proposing to extend daylight savings time is a
GalinKa [24]

Answer:

Right of X = 635.5

Step-by-step explanation:

By using the normal approximation to the Binomial random variable, we usually make use of continuity correction.

According to the rule of continuity;

P(X ≤ k) becomes  P( X ≤ K + 0.5)

P(X < K) becomes P(X < K - 0.5)

P(X ≥ K) becomes P(X ≥ K - 0.5)

P(X > K) becomes P(X > K + 0.5)

P(X = K) becomes P(K - 0.5 ≤ X ≤ K + 0.5)

From the given question, Assume that we are to determine the probability that more than 635 Americans support the bill.

Then we use the > sign.

∴

P(X > K ) becomes P(X > K + 0.5)

P(X > 635) becomes P(X > 635 + 0.5)

⇒ P(X > 635.5) tot the right.

Right of X = 635.5

Anna wants to buy a car in two years and wants to have $10,000 for the purchase. How much will Anna need to deposit today in an
Brut [27]

Answer:

Anna will need to deposit \$9,050.25

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=2\ years\\A=\$10,000\\ r=0.05\\n=12  

substitute in the formula above  and solve for P

10,000=P(1+\frac{0.05}{12})^{12*2}  

10,000=P(1.0042)^{24}  

P=10,000/(1.0042)^{24}    

P=\$9,050.25
