Answer:

1) 1/10

2) 1/2

3) 1/5

Step-by-step explanation:

1)

1 favorable outcome and 10 total outcomes.

$P(3) = \frac{1}{10}$

2)

5 favorable outcomes and 10 total outcomes

$P(even) = \frac{5}{10} = \frac{1}{2}$

3)

2 favorable outcomes and 10 total outcomes

$P(multiples\ of\ 5) = \frac{2}{10} = \frac{1}{5}$

PLEASE HELP!!!!!!!!<br> What is the 8th term of this sequence? 1,-1/2,1/4,-1/8

Tom [10]

This is a geometric sequence with first term 1 and common ratio -1/2. r=-1/2.

a(n) = a(1)*(r)^(n-1).

Check: If n=2 our formula must return -1/2. Does it?

a(2) = 1(-1/2)^(2-1) = (-1/2)^1 = - 1/2. Yes.
a(3) should be 1/4. Is it? a(3) = (-1/2)^(3-1) = 1/4 Yes.

Then a(8) = (-1/2)^(8-1) = (-1/2)^7 = -1 / 2^7 = -1/128 (answer)

Regina had 3/4 of a gallon of orange juice. She drank 1/4 of a gallon of orange juice. What fraction of the juice in the gallon

yKpoI14uk [10]

Answer:

Regina drank 2/4 gal. of orange juice

Step-by-step explanation:

She starts off at 3/4 which makes the equation: 3/4 - 1/4=x

3/4-1/4 equals 2/4 which gets reduced and simplified to 1/2.

Sec²θ=4+2tan²θ<br>Find θ

Marina86 [1]

Recall the Pythagorean identity,

$\sec^2\theta=1+\tan^2\theta$

So we have

$\sec^2\theta=4+2\tan^2\theta$

$1+\tan^2\theta=4+2\tan^2\theta$

$-3=\tan^2\theta$

But squaring any real number always gives a non-negative number, so there are no real solutions to this equation.
