You take 4/15 and make the denominator 315 

4/15 = ?/315 
15 x 21 = 315
4 x 21 = 84 
4/15 = 84/315 

so 84 of 315 members are male 

315 - 84 
= 231 

231 are female

Alona [7]

Based on the information provided and the requirements to organize the students, Jon most likely has 23 students.

<h3>How many students are needed to organize them in a rectangular grid?</h3>

In general, Jon will need a number that is not prime as this type of number will not allow him to complete all the grid.

<h3>Which are possible numbers?</h3>

20 = A rectangular grid of 5 x 4 seats can be arranged

21= A rectangular grid of 7 x 3 can be arranged

22 = A rectangular grid of 2 x 11 can be arranged

23 = It is impossible to organize 23 seats in a rectangular grid without gaps

3g2+4g+1=0 solve for g
gulaghasi [49]
- - Lets solve for G.

Keep in mind: G is acting as a unknown variable, commonly used as "x"
So we need to find the variable, and then we solve for g until we get "0" for our problem.
Okay so lets start off by factoring our equation, in this case you do left first.

3g+1*g+1=0
Alright, now we can set out "o" as the equal to all of our factors.
g+1=0
And now you need to solve for that,
And you get -1 for our answer.

Final answer: g=-1

7. A crate of soft drinks contains 9 bottles of coke, 6 bottles of pepsi and 4 bottles of limca. Ademola picks one bottle of sof
Mekhanik [1.2K]

The probability that the events (a) they both picked Limca = 0.04, (b) Ademola only picked Pepsi = 0.32, (c) They both picked the same brand = 0.33 (d) They picked different brand=0.67.

<h3>What is probability?</h3>

Probability is the fraction of the required outcome event divided by the number of possible outcomes of events.

Total possible outcome of the event of picking drinks contained in the crate = 19

Hence, we can compute the following as follows;

(a) The probability they both picked Limca = (4/19)×(3/18)

Limca = 12/342

Limca = 0.04

(b) The probability Ademola only picked pepsi = 6/19

pepsi = 0.32

(c) The probability they both picked the same brand = (9/19)×(8/18)+(6/19)×(5/18)+(4/19)×(3/18)

=(72+29+12)/342

= 114/342

= 0.33

(d) The probability they picked different brand = (9/19)×(6/18)+(9/19)×(4/18)+(6/19)×(9/18)+(6/19)×(4/18)+(4/19)×(9/18)+(4/19)×(6/18)

The probability they picked different brand = (54+36+54+24+36+24)/342

The probability they picked different brand = 228/332

The probability they picked different brand = 0.67

Therefore, the probability for events (a) is 0.04, (b) is 0.32, (c) is 0.33 and (d) is 0.67.
