Answer:

A) affinity pattern

Explanation:

Affinity patterns show associations that occur among objects in the real world. These objects that show affinity patterns or association patterns are not complementary to each other and sometimes may not even be related to each other.

In this case, the fact that it is raining is probably what causes the 85% in cab service usage. If we analyze them separately, cab service and rain have nothing to do with each other, but when it rains more cabs are used.

What is the typical relationship between time and interest rate everfi?
klasskru [66]
<span>Interest rate is directly proportional to time. An interest rate is the amount of money due per period or a proportion of the amount borrowed or deposited. The total interest depends on the principal sum and the length of time over which it is lent or deposited. Therefore, the value of money will depend on interest rate and time. The longer time of debt or bank deposit, the higher interest rate.</span>

Assume that your parents wanted to have 120,000 saved for college by your 18th birthday and they started saving on your first bi
Andrei [34K]

Answer:

save each year to reach their​ goal is $2152.48  

save each year to reach their new ​goal is $2869.97

Explanation:

given data

amount saved = 120,000

Rate of Interest earned =  12.0 %

time = 18th birthday  

solution

we consider here annual savings is =  P

we use here formula for future value of annuity  that is

future value of annuity = P ×  \frac{(1+r)^n -1 }{r}    ................1

here r is rate and n is time period

put her value

$120,000  = P ×  \frac{(1+0.12)^{18} -1 }{0.12}  

solve we get P = $2152.48

save each year to reach their​ goal is $2152.48  

and

for $160,000 at 18th Birthday

we consider here  annual savings =  P

so from equation 1

we put here value

future value of annuity = P ×  \frac{(1+r)^n -1 }{r}

$160,000  = P ×  \frac{(1+0.12)^{18} -1 }{0.12}  

solve and we get P = $2869.97

save each year to reach their new ​goal is $2869.97

If you want $1,000 three years from now and you earn 4 percent on your savings, how much do you need to deposit?
harkovskaia [24]

Answer:

d. $889

Explanation:

The computation of the deposit amount is shown below:

Principal = Amount ÷ (1 + interest rate)^number of years

              = $1,000 ÷ (1 + 4%)^3 years

              = $1,000 ÷ 1.124864

              = $889

Simply we divide the amount by the interest rate and the number of years so that the exact value can arrive

Most businesses adopt a bureaucratic organization in order to speed up their decision making process.
Nina [5.8K]
This is actually false. The effect is quite the opposite, things are really slowed down but in return you get safety and security and unbiased procedures. That's why you need a lot of various paperwork for example when you get a driver's license, instead of they just deciding to give it to you. Bureaucracy prevents things like corruption and personal bias.
