Answer:

b^2=161

Step-by-step explanation:

So when we deal with triangles the formula is a^2+b^2=c^2

We know that the hypotenuse of the triangle is 15 which is our c^2.

a^2= 64

64+b^2=15^2

64+b^2=225

Then subtract 64

B^2=161

Find the common ratio of the geometric sequence 36, 6, 1, 16, ... . Write your answer as an integer or fraction in simplest form

nalin [4]

Answer:

Step-by-step explanation:

The common ratio is the constant found by dividing any term by the previous term.

r=6/36=1/6

r=1/6

I am assuming the 16 at the end of the sequence was a typo. IF 16 was at the end of the sequence it is NOT a geometric sequence as there would not be a common ratio for all terms.

Expand and simplify 4 (3a-4)

Anettt [7]

Answer:

$a=\frac{4}{3}$

Step-by-step explanation:

In this situation, we need to first do the distributive property.

$4 (3a-4)= 12a -16$

I am assuming that the equation would be equal to zero....

$12a-16=0$

Add 16 to both sides

$12a=16$

Divide 12 to both sides

$a=\frac{16}{12}$

Simplify

$a=\frac{4}{3}$

Number of male students who got 'A' in the test is 11
Number of female students who got 'A' in the test is 19
Total students who got 'A' in the test is 30
Probability that the male student got an 'A' is P(A | male) = (Number of male students who got 'A' in the test)/(Number of total students who got 'A' in the test) = 11/30
