An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water what is the probability of getting a drink that does not contain fruit juice

Answers

Answer 1
Answer:

Answer: (3)/(8)

Step-by-step explanation:

Given: An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water.

Total drinks= 10+15+15 = 40  (Total outcomes)

Number of drink that does not contain fruit juice = Number of bottles of water = 15  (Favorable outcomes)

The probability of getting a drink that does not contain fruit juice = (Favorable\ outxcomes)/(Total\ outcomes)

=(15)/(40)\n\n=(3)/(8)

So, the required probability = (3)/(8) .

Megan has 25 phone numbers stored in her cell phone. Abby has some phone numbers stored in her cell phone. Together they have a total of 61 phone numbers stored. If n = the number of phone numbers Abby has stored in her cell phone, write a mathematical sentence to express the information above.

Answers

The mathematical sentence should be: 25+n=61
25+N=61.
N= 36
So there is 36 numbers in Abby's cell phone.

3 - 3i

Answers

z = a + bi
z = 3 - 3i

      |z| = √(a² + b²)
|3 - 3i| = √(3² + 3²)
|3 - 3i| = √(9 + 9)
|3 - 3i| = √(18)
|3 - 3i| = √(9 × 2)
|3 - 3i| = √(9)√(2)
|3 - 3i| = 3√(2)

tanΘ = b/a
tanΘ = ⁻³/₃

multiply m to both sides
m*h-1=2f
divide 2 both sides
mh-1/2=F
