A certain stock exchange designates each stock with a one-, two-, or three-letter code, where each letter is selected from the 2

Sophie [7]

Answer: Option 'e' is correct.

Step-by-step explanation:

Since we have given that

Number of letters of the alphabet = 26

Number of letters in code :

One letter code, or two letter code, or three - letter code.

Since repetition of letters are allowed, then

if it is one letter code, the number of arrangement would be 26.

If it is two letter code, the number of arrangements would be

$26\times 26\\\\=26^2\\\\=676$

If it is three letter code, the number of arrangements would be

$26\times 26\times 26\\\\=26^3\\\\=17576$

So, Number of different stocks to uniquely designate with these codes would be

$26+676+17576\\\\=18278$

Hence, Option 'e' is correct.

brilliants [131]

Answer:

546,397 people

Step-by-step explanation:

We solve for the above question, using the formula for Exponential growth

The formula is given as

P(t) = Po (1 + r)^t

Po = Initial population = 310,000

r = Exponential growth rate = 6.5% = 0.065

t = Time in years = 9

P(t) = Population size after time t

Hence:

P(t) = 310,000 × (1 + 0.065)⁹

P(t) = 546,396.82088 people

Approximately =546,397 people

The population will be 546,397 people after 9 years.

How do I do this question

Alekssandra [29.7K]

We know that
circumference=2*pi*r
for r=65/2----> r=32.5 cm
circumference=2*pi*32.5-----> 204.1 cm
so
one revolution <span>of Emma’s bicycle</span> is equal to 204.1 cm-----> 2.041 m
3.2 km-------> 3200 m
1 revolution---------> 2.041 m
x rev------------> 3200 m
x=3200/2.041 ----> x=1567.86 revolutions

the answer is
1567 complete revolutions
