Answer:

The answer is 60.

Step-by-step explanation:

here, let another number be x.

according to the question the number when increased by 30% will be 78. so,

x+ 30% of x =78

now, x+ 30/100×x =78

or, x+0.3x=78

or, 1.3x=78

Therefore the another number is 60.

Hope it helps...

Answer:

Step-by-step explanation:

Rate = 10%

Time = 2 years

Initial CO2 = 280000 metric ton

1st year

10% × 280000

= 28000 metric ton.

2nd year

10% × (280000 - 28000)

= 25200 metric ton.

Metric ton of CO2 produced at the end of the 2nd year = 252000 - 25200

= 226800 metric ton of CO2.

Answer: 0.750

Step-by-step explanation:

Let p be the population proportion .

We are given that a sample of 400 voters reveals that 300 would support her in the November election.

Then the sample proportion for this situation will be :-

$\hat{p}=\dfrac{300}{400}=0.750$

Since the sample proportion is the best point estimate for the population proportion.

Therefore, the estimated value of the population proportion =0.750

SIZIF [17.4K]

Answer:

A) $93,504.818

B) $40,000

C) $53,504.818

Step-by-step explanation:

Yearly contribution ( periodic payment) = $4000

Period (p) = 10years

Additional period(y) = 5years

Annual interest(r) = 9% = 0.09

Future value (FV) =

periodic payment [(1 + r)^y - 1] / r

4000 [(1 + 0.09)^10 - 1 / 0.09]

4000[1.09^10 - 1 / 0.09]

4000[1.3673636 / 0.09]

4000(15.192929)

= 60771.716

If left for five more years:

FV = 60771.716(1 + r)^n

FV = 60771.716(1 + 0.09)^5

FV = 60771.716(1.09)^5

FV = 60771.716(1.5386239549)

FV = $93,504.818

B) MR. HUGHES CONTRIBUTION :

Periodic payment × p ; $4000 was deposited annually for 10 years.

$4000 × 10 = $40,000

C) Interest = Future value - contribution

$93,504.818 - $40,000

= $53,504.818
