The population of a small town in Alabama is 382 people. If the growth rate is 0.7%, what will its population be in 30 years?

1 answer:

4 0

Formula for growth:

y = initial • (percent growth + 1)^time/frequency of growth

So, since initial population is 382

Percent growth is 0.007

The time is 30 years

And it goes it by .07% every 1 year,

y = 382 • (1.007)^30/1

y= 470.9203732 people

Since we can’t have 0.9 of a person, the population after 30 years will be 470 people.

There were 230 shoppers at an electronics store on opening day. The specials that day allowed 21% of shoppers to receive a free

anastassius [24]

Answer:

a) About 48 of the shoppers, that is $230\frac{21}{100}$ of the shoppers, received a free set of earbuds.

b) About 58 shoppers, that is $\frac{230}{4}$ received $5 off their first purchase.

Step-by-step explanation:

a. About how many shoppers received a free set of earbuds?

21% out of 230. So

$230\frac{21}{100} = 2.3(21) = 48.3$

About 48 of the shoppers, that is $230\frac{21}{100}$ of the shoppers, received a free set of earbuds.

b. About how many shoppers received $5 off their first purchase?

25% out of 230, so:

$230\frac{25}{100} = 230\frac{1}{4} = \frac{230}{4} = 57.5$

About 58 shoppers, that is $\frac{230}{4}$ received $5 off their first purchase.

The probability that Latisha orders french fries at lunch is .32 and the probability that she orders a grilled cheese and fries

EastWind [94]

There is a typo error in the last part of the question. The corrected part is-

"If the probability that she orders just a grilled cheese sandwich is .76, what is the probability that she will order a grilled cheese or fries?"

Answer:

The probability that she will order a grilled cheese sandwich or fries is <u>0.43.</u>

Step-by-step explanation:

Given:

Probability of ordering fries is, $P(F)=0.32$

Probability of ordering cheese sandwich is, $P(S)=0.76$

Probability of ordering both sandwich and fries is, $P(F\cap S)=0.65$

Probability of ordering cheese sandwich or fries is given by the union of both the events 'F' and 'S' given as $P(F\cup S)$ .

Now, using addition theorem of probability, we get:

$P(F\cup S)=P(F)+P(S)-P(F\cap S)\\P(F\cup S)=0.32+0.76-0.65\\P(F\cup S)=0.43$

Therefore, probability of ordering cheese sandwich or fries is 0.43.
