The answer is G because If Mia is 12 and she is 2 1/2 years older than Chloe that means Chloe is 9 1/2 since 12 - 2 = 10 - 1/2 =  9 1/2. Then to find Allen's age, you subtract 9 1/2 - 6 1/2 = 3. 

YOU'RE WELCOME! (I know how it feels to struggle) :)

Suppose that a recent poll found that 40% of adults in a certain country believe that the overall state of moral values is poor.
shusha [124]

Answer:

Step-by-step explanation:

Let X be the no of adults whose feelings the state of morals is poor.

X has two outcomes and each trial is independent of the other

X is Bin with p = probability for success in each trial =40%=0.40

n=no of adults surveyed = 55

a)  The probability that exactly 21 of those surveyed feel the state of morals is poor is

P(X=21) = 40C21 (0.4)^{21} (1-0.4)^{19} \\=0.03519

(b)  The probability that no more than 22 of those surveyed feel that state of morals is poor is

=P(X

(c)  The probability that more than22 of those surveyed feel the state of morals is poor is

P(X>22)\\=1-0.9811\\=0.0119

(d)  The probability that 15 or 16 believe the state of morals is poor is

=P(X=15)+P(X=16)\\=0.1228+0.1279\\=0.2507

Jenn invests $2150 at 2% compounded continuously. How many years will it take her to accumulate $2733.19 in the account?
gavmur [86]

Answer:

12 years

Step-by-step explanation:

From the formula;

A = P(1 + r)^n

A = Amount  = $2733.19

P = Principal = $2150

r = rate = 2%

n = time in years = ???

2733.19 = 2150(1 + 0.02)^n

2733.19/2150 = (1 + 0.02)^n

1.27 = (1.02)^n

Taking logarithm of both sides

log 1.27 = n log 1.02

n= log 1.27/log 1.02

n= 0.1038/0.0086

n = 12 years
