Chance of finding a bug = 0.35

Chance of not finding a bug = 1 - 0.35 = 0.65

Probability of finding a bug in the first 3 programs =

Probability of not finding a bug in 2 out of the 3 and finding a bug in 1.:

0.65^2 * 0.35 = 0.147 = 0.15

Answer is A.

2.

Probability of heads = 0.50

Probability of tails = 0.50

Probability of heads on the fourth attempt = tails x tails x tails x heads = 0.5 x 0.5 x 0.5 x 0.5 = 0.0625

The answer is B.

How many different committees can be formed from 11
Vikki [24]

Answer:

2 Committees

Step-by-step explanation:

2 Committees and 3/4 of a committee

There are only 11 teachers so that means only 2 committees can be filled with 4 teachers if that is the max amount per committee.

There are more than enough students so no need to worry on them.

11 divided by 4 = 2.75

Find the missing term (x^12)^5 x (x^-2)^9 x what =(x^40)^5
Annette [7]

Answer:

x^{158}

Step-by-step explanation:

We are given,

(x^{12} )^{5} \times (x^{-2} )^{9} \times y = (x^{40} )^{5}.

It is required to find the value of y.

Now, on simplifying above equation, we get,

x^{60} \times x^{-18} \times y = x^{200}

i.e. x^{42} \times y = x^{200}

i.e. y = x^{200} \times x^{-42}

i.e. y = x^{158}

Hence, the missing term is x^{158}.

Which word best describes the degree of overlap between the two data sets? Low, High, None, Moderate
zlopas [31]

Answer:

In case of data set given with the question, the word that best describes the degree of overlap between the two data sets is low.

Step-by-step explanation:

Overlapping of two data sets means they contain common data or they have common elements in them.  

In case of given data set, the elements are represented by 'x'.

If we compare both, the elements at line 30 and 35 overlap.

We conclude that out of 15 elements in each data set,  only two of them overlaps. Hence the degree of overlap is low.

Find the circumference of a circle whose area is 247 ft2.
gizmo_the_mogwai [7]

Answer:

B is the answer

Step-by-step explanation:

A = πr²

24π = πr²

24 = r²

24 = r²

\sqrt{24} = r

r = \sqrt{4}\sqrt{6} = 2\sqrt{6}

C = 2πr

C = 2π(2\sqrt{6})

C = 4\sqrt{6}π
