The probability, P, that a person responds to an advertisement can be modeled by the exponential function P = 1 – e^-0.047t. In
Ray Of Light [21]

Answer:

c. 60.9%

Step-by-step explanation:

Given:

The probability P that a person responds to an advertisement can be modeled by the function:

P=1-e^{-0.047t}

where t represents number of days since the advertisement first appeared.

To find the probability that a person has responded after 20 days.

Solution:

In order to find the probability that a person has responded after 20 days, we will plugin t=20 in the formula given.

We have:

P(t)=1-e^{-0.047t}

Plugging in t=20

P(20)=1-e^{-0.047(20)}

P=1-e^{-0.94}

P=1-e^{-0.047t}

P=1-0.3906

P=0.6094

Thus, probability P after 20 days = 0.6094

The probability in percentage can be given = 0.6094\times 100= 60.9%

Sue has $2.20 in dimes and nickels. If she has 13 more dimes than nickels, how many of each coin does she have?
dem82 [27]
10d+5n=220
divide both sides by 5
2d+n=44

d=13+n
sub 13+n for d in other equatin

2(13+n)+n=44
26+2n+n=44
26+3n=44
minus 26 both sides
3n=18
divide both sides by 3
n=6
sub back

d=13+n
d=13+6
d=19


19 dimes
6 nickles

Please Help!!!
DochEvi [55]

Sally earns per hour = $12

Sally works for in a week = 16 hours.

So, Sally earns in a week = 12\times16=192

Sally can save money each week= 20% of 192

\frac{20}{100}\times192=38.40

A. How much does she earn each week ? Sally earns $192 in a week.

B. How much money will she save each week? Sally will save $38.40 each week.

C. How much money will she save each month (assume there are 4.3 weeks in a month)

Savings of 1 week = $ 38.40

Savings of 4.3 weeks = 4.3\times38.40=165.12

Hence, she will save $165.12 in a month.

D. How many months will it take her to save the money?

Total money needed = $1800

Number of months needed to collect this amount =

\frac{1800}{165.12}=10.90

Hence, it will take 11 months approx to save $1800.

Is the relationship shown by the data linear? x -9, -5, -1, 3 y -2,-7,-12, -17
Temka [501]
                x               y
            ------           -----
              -9              -2
             -5               -7
             -1              -12
              3               -17

ur x's all have a difference of 4, and ur y's all have a difference of -5...so yes, this is linear with a slope of (-7+2) / (-5 + 9) = -5/4
