only chocolate and vanilla ice cream cones are sold at an ice cream store. In one day, the number of chocolate cones sold was 1 more than 4 times the number of vanilla cones sold. A total of 121 cones sold that day

Answers

Answer 1

Answer: I just had this question for homework too!

c = 4v + 1
v + c = 121

Now use substitution.

v + 4v + 1 = 121
5v + 1 = 121
5v = 120
v = 24

The answer is 24.

Answer 2

Answer: Here's the equation:
4x+1+x = 121. Where x is equal to the amount of vanilla cones.
5x + 1 = 121
5x = 120
x = 24
There were 24 vanilla and 97 chocolate.

Answers

Answer:

we have x = y +2

now we put that value in other eq.

2(y+2)-3y = 1

2y+4-3y = 1

2y-3y = 1-4

-y= -3 (cut the signs on both side)

y= 3

now we put y value in the other given equation

x = 3+2

x = 5

we have y as 3 and x as 5.

The probability that Shelly will go to a movie (event A) on Friday is 0.78, and the probability that Danielle will go to a movie (event B) the same day is 0.63. The probability that Shelly will go to a movie, given that Danielle goes to a movie, is 0.87. Which statement is true?
a. Events A and B are independent because P(A|B) ≠ P(A).
b. Events A and B are independent because P(A|B) = P(B).
c. Events A and B are dependent because P(A|B) = P(A) x P(B).
d. Events A and B are dependent because P(A|B) ≠ P(A).
e. Events A and B are dependent because P(A|B) = P(A).

Answers

The right answer for the question that is being asked and shown above is that: "c. Events A and B are dependent because P(A|B) = P(A) x P(B)."The probability that Shelly will go to a movie, given that Danielle goes to a movie, is 0.87.

Answer:

Events A and B are independent because P(A and B) = P(A) × P(B).

Out of 100 students,15 passed in english, 12 passed in mathematics, 8 in science, 6 in english and mathematics, 7 in mathematics and science, 4 in english and science, 4 in all three. find how many passed1)in english and mathematics but not science
2)in mathmatics and sciecnce but not in english
3)in mathematics only
more than one subject only

Answers

Because there are 4 students who passed in all subjects, we can say that only 2 students passed in English and Mathematics only, only 3 students passed in Mathematics and Science only, and no one passed in English and Science only.

Given that we have deduced the number of students who passed in two subjects, we can now solve for the number of students who passed only one subject.
English = 15 - (4 + 2 + 0) = 9
Mathematics = 12 - (4 + 3 + 2) = 3
Science = 8 - (4 + 3 + 0) = 1

1. In English but not in Science,
9 + 2 = 11
2. In Mathematics and Science but not in English
3 + 3 + 1 = 7
3. In Mathematics only
= 3
3. More than one subject only
3 + 4 + 2 + 9 = 18

English = 15 - (4 + 2 + 0) = 9

Mathematics = 12 - (4 + 3 + 2) = 3

Science = 8 - (4 + 3 + 0) = 1

1. In English but not in Science,

9 + 2 = 11

2. In Mathematics and Science but not in English

3 + 3 + 1 = 7

3. In Mathematics only

= 3

3. More than one subject only
