If 18 percent of the beads in a bag are green, 25 percent are red and 40 percent are purple. What is the probablity of choosing
sweet [91]

Answer:

P(G\ then\ R)=0.045

Step-by-step explanation:

From the question we are told that:

Percentage of  Green beads P_g=18

Percentage of  Red beads    P_r=18

Percentage of Purple beads P_p=18

Therefore

Probability of choosing a Green bead is

 P(G)=0.18

Probability of choosing a Red bead is

 P(R)=0.25

Generally the equation for choosing a green bead then a red bead is mathematically given by

Since Outcomes are independent

 P(G\ then\ R)=0.18*0.25

 P(G\ then\ R)=0.045

What is an equation in point-slope form of the line that
-Dominant- [34]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (-3, -1) and slope 2

The equation is

<h2>y + 1 = 2(x + 3)</h2>

Hope this helps you

B. What are the second and third terms of this arithmetic sequence? 80, 페, 페, 125,...........
nataly862011 [7]

The 2nd and 3rd term of an AP is found to be (a₂ = 95) and (a₃ = 110).

<h3>What is the sequence of AP arithmetic progression?</h3>

In Arithmetic Progression, the difference between the two numerical orders is a fixed number (AP). Arithmetic Sequence is another name for it.

We'd come across a few key concepts in AP that had been labeled as:

  • The first term (a)
  • Common difference (d)
  • Term nth (an)
  • The total of first n terms (Sn)

As shown below, the AP can also be referred to in terms of common differences.

  • The following is the procedure for evaluating an AP's n-th term:  an = a + (n − 1) × d
  • The arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].
  • Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ......      = an - an-1.

Now, the given sequence is; 80, _, _, 125.

The series comprises of four given terms.

Let the first term be 'a₁' = 180.

The second term be 'a₂'.

The third term be 'a₃'.

And, the fourth term is 'a₄' = 125.

Use the nth term formula to find the common difference 'd'.

n-th term:  an = a + (n − 1) × d

a₄ = a + (n - 1)d

125 = 80 + (4 - 1)d

45 = 3d

d = 15

Thus, the common difference is 15.

The second term is calculated as;

a₂ = a₁ + d

a₂ = 80 + 15

a₂ = 95.

The third term is estimated as;

a₃ = a₂ + d

a₃ = 95 = 15

a₃ = 110

Therefore, the 2nd and third term of an AP is computed as 95 and 110.
