one+four+three=eight pens.
Two pens are selected without replacement.
Need probability of selecting two black pens.
Probability of selecting first black pen is four out of eight, 4/8
Probability of selecting second black pen is three remaining black pens out of the remaining 7 pens = 3/7
Probability of both events happening is the product of the two probabilities, according to the multiplication rule.
Therefore probability of selecting two black pens out of the initial eight pens
=(4/8)(3/7)=3/14=0.2143 (to the ten-thousandth).
Rounding to the hundredth will give you the required answer.
Answer:
a =
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.:
<em>Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Find the unknown side length using the Pythagorean theorem and then find the values of the six trigonometric functions for angle B. when b=3 and c=4</em>.
My answer:
We will Pythagoras theorem, which states that the sum of squares of two legs of a right triangle is equal to the square of the hypotenuse of right triangle. Because the question says that ABC is a right triangle.
Given that: b=3 and c=4
so a =
We know that tangent relates opposite side of a right triangle with adjacent side.

This question is incomplete, the complete question is;
Vic bought a new plasma TV for $2400. He made a down payment of $200 and then financed the balance through the store. Unfortunately, he was unable to make the first monthly payment and now pays 6% interest per month on the balance (while he watches his TV).
What is Vic's Monthly interest payment ( Assume interest rates are 1/12 of annual interest rates)
Answer: Vic's Monthly interest payment is $132
Step-by-step explanation:
Given that;
Purchase cost of plasma Tv = $2400
down payment made = $200
so,
Balance financing from store = $2400 - $200 = $2,200
also given that Interest rate is 6% per month6
Now Monthly interest payment will be;
⇒ financing amount × interest rate
⇒ 2200 × (6/100) = 132
Therefore, Vic's Monthly interest payment is $132
