A recent study found that 81?% of? breast-cancer cases are detectable by mammogram. Suppose a random sample of 11 women with bre
elena-s [515]

Answer:

9.847 %

Step-by-step explanation:

Be p1 the probability that the mammogram detect breast cancer in a woman.

p1=81%.

The probability 'P' that independent and consecutive 'n' singular events with p probability occur is:

P=p_{1} ^{n}

In this case:

P: Probability that breast cancer be detected on 11 women with breast cancer.

P=0.81^{11}=0.09848

P=9.847 %

An account is opened with $7,595.96 with a rate of increase of 2% per year. After 1 year, the bank account contains $7,746.90. A
Sav [38]

Answer:

It's C

Step-by-step explanation:

y = 7,595.96(1.02)x

the initial beginning value times .02 after adding 1 to it so you would get 1.02 instead since it's an increase raised by x which indicates how many years it was to reach the new value.

The explicit formula of an arithmetic sequence is f(n)=5+12(n-1)f(n)=5+12(n−1)f, left parenthesis, n, right parenthesis, equals,
Serga [27]

The recursive formula of the sequence is f(n) = 12 + f(n -1), where f(1) = 5

<h3>How to determine the recursive formula?</h3>

The explicit formula of the arithmetic sequence is given as;

f(n) = 5 + 12(n - 1)

Open the bracket

f(n) = 5 + 12n - 12

Evaluate the like terms

f(n)= 12n - 7

Calculate f(1) and f(2)

f(1)= 12(1) - 7= 5

f(2)= 12(2) - 7= 17

The difference between f(1) and f(2) is 12

Hence, the recursive formula of the sequence is f(n) = 12 + f(n -1), where f(1) = 5
