what is the rhee and pamela are two of the five members of band. every week the band picks 2 members at random to play on their own for five minutes. what is the probability that rhee and pamela are chosen this week.

Answers

Answer 1

Answer: First you need to count the number of different two people groups you can make.

That is 5x4/2 = 10 different groups (this is because you can choose the first member from 5 different persons and the second member from 4 different persons, which makes 5 x 4; then you realize that in that way every couple is counted twice and so you have to divide by 2).

If you do not see that, you can count in this way. Identify every person with one letter: a, b, c, R and P

you can do these different two people groups:

ab
ac
aR
aP

bc
bR
bP

cR
cP

RP

Thos are the ten different groups.

Rhee and Pamela is one group, so the probability of chosing it is

1/10 = 0.1

A circle is shown. 2 secants intersect outside of the circle to form angle 1. The measure of the first arc formed is b degrees, and the angle of the second arc is a degrees. Arc c degrees is outside of the secants. Which formula would be used to find the measure of angle 1? One-half(a° + b°). One-half(a° – c°). One-half(b° + c°). One-half(a° – b°).

Answers

A formula that can be used to determine the measure of angle 1 include the following: D. 1/2(a° – b°).

What is the theorem of intersecting secants?

In Mathematics and Euclidean Geometry, the theorem of intersecting secants states that when two (2) lines intersect outside a circle, the measure of the angle formed by these lines is equal to one-half (½) of the difference of the two (2) arcs it intercepts.

By applying the theorem of intersecting secants to the circle, we can reasonably and logically deduce that the measure of angle 1 or m∠1 can be calculated as follows:

m∠1 = 1/2(a° – b°)

m∠1 = (a° – b°)/2

Chris divided 1/2 pound of nails into 6 small bags. He wants all bags to have equal weight. How much does each bag weigh? A. 1/2 pound.B. 1/3 pound
C. 1/6 pound
D. 1/12 pound

Answers

D, 1/12 pound. A way to think of this is that if there is 1/12 in 6 different bags, you get 6/12, which is equivalent to 1/2

During the month of June, Ava kept track of the number of days she saw birds in her garden. She saw birds on 18 days of the month. What is the experimental probability that she will see birds in her garden on July 1st?

Answers

There are 30 days in the month of June. Out of the 30 days, Ava saw birds on 18.

P(bird)=18/30

We can simplify the fraction by dividing both sides by 2.

P(bird)=18/30=9/15

9/15=0.6=60%

Theres a 9/15 or 60% chance that she will see a bird on July 1st.
