In a math class with 28 students, a test was given the same day that an assignment
was due. There were 18 students who passed the test and 23 students who completed
the assignment. There were 16 students who passed the test and also completed the
assignment. What is the probability that a student who passed the test did not
complete the homework?

Answers

Answer:

Probability that a student who passed the test did not  complete the homework = 0.07

Step-by-step explanation:

Given:

Total number of students = 28

Number of students who passed the test = 18

Number of students who completed  the assignment = 23

Number of students who passed the test and also completed the  assignment = 16

To find: probability that a student who passed the test did not  complete the homework

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favorable outcomes/total number of outcomes

Let A denotes the event that students passed the test and B denotes the event that students completed  the assignment

P(A only) = [tex]P(A)-P(A\cap B)[/tex]

Here,

[tex]P(A)=\frac{18}{28}\,,\,P(A\cap B)=\frac{16}{28}[/tex]

So,

[tex]P(A\,\,only)=\frac{18}{28}-\frac{16}{28}=\frac{2}{28}=\frac{1}{14}=0.07[/tex]

Therefore,

probability that a student who passed the test did not  complete the homework = 0.07

The roads that connect three buildings form a right triangle. Use the image to find the distance between the library and the museum.

Answers

Answer:400 yards

Step-by-step explanation:Let L represents the position of library, R represents the restaurant and M represents the museum,

Since, By the given diagram,

∠MLR = 90°,

LR = 300 yd,

RM = 500 yd,

So, by the Pythagoras theorem,

By substituting the values,

Hence, the distance between library and museum is 400 yards.

2-4(3x-y)=8(4-y)-39x and 8(4-y)-39x=6(y-x)

Answers

Answer:

X = -(146/123) , Y = 21/41

Step-by-step explanation:

2-4(3x-y) = 8(4-y)-39x

2-12x-4y = 32-8y-39x

39x-12x+8y-4y = 32-2

27x+4y = 30

27x+4y-30 = 0

8(4-y) -39x = 6(y-x)

32-8y-39x = 6y-6x

32-8y-6y-39x+6x = 0

Which inequality has -25 in its solution set?
y + 11 > -9
y - 17 Less-than-or-equal-to -46
30 Less-than-or-equal-to y + 5
y + 20 > -30

Answers

Answer:

Let's check one by one:

y + 11 > -9

-25 + 11 > -9

-14 > -9 (wrong)

y - 17 <= -46

-25 - 17 <= -46

-42 <= -46 (wrong)

30 <= y + 5

30 <= -25 + 5

30 <= -20 (wrong)

y + 20 > -30

-25 + 20 > -30

-5 > -30 (Right)

=> Last option is solution

Hope this helps!

:)

The required inequality that contains -25 in its solution is y +20 > -30.
Option D is correct.

Number of inequality is given y + 11 > -9 , y - 17≤  -46, 30 ≤ y + 5, y + 20 > -30, the inequality that contains -25 to its solution of set to be determine.

What is inequality?

Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

1)  y + 11 > -9
    y >-20
It does not contain -25. in its solution set.

2)  y - 17≤  -46
     y  ≤ -29

It does not contain -25. in its solution set.

3) 30 ≤ y + 5
   25 ≤ y
It does not contain -25. in its solution set.

4) y + 20 > -30
    y  > -50
It does contain -25 in its solution.

Thus, the required inequality that contains -25 in its solution is y +20 > -30.

Five times the sum of a number and 3 is the same as 3 times the difference of twice the number and 1.
What is the number?

Answers

Answer:

12

Step-by-step explanation:

5(x+3) = 3(2x-1)

5x+15 = 6x-3

15-3 = 6x-5x

12 = x

x = 12

The number should be 12.

Given that,

Let us assume the number be x.Five times the sum of the number & 3 should be the same because 3 times is the difference of the twice of the number and 1.

Based on the above information, the following equation should be made:

5(x+3) = 3(2x-1)

5x+15 = 6x-3

15-3 = 6x-5x

12 = x

x = 12

Therefore we can conclude that the number is 12.

1521 orange trees are planted in a garden in such a manner that there are as many trees in a row as there are rows in the garden. The number of trees in each row is

Answers

Answer: 39

Step-by-step explanation:

Total number of orange trees = 1521

Note :

There are as many trees in a row as there are rows in the garden.

Therefore :

Number of rows in the garden = number of trees in a row

Let the number of rows in the garden = y

Hence, the number of trees in a row also = y

Total number of trees in the garden = number of trees in a row × number of rows in the garden

Total number of trees in the garden = y × y

1521 = y × y ; 1521 = y^2

y = √1521

y = 39

Answer:

no.f trees in each row =39

Step-by-step explanation:

Total number of orange trees = 1521

Note :

There are as many trees in a row as there are rows in the garden.

Therefore :

Number of rows in the garden = number of trees in a row

Let the no.f trees in each row =x

let the no.f rows=x

therefore total no.f trees =x raised to 2

x raised to 2 =1521

therefore x=39

there fore no.of rows =39

no.f trees in each row =39

If 5,x,y,40 are in geometrical progression, find x and y respectively.

Answers

Answer:

x = 10, y = 20

Step-by-step explanation:

Because this is a geometric sequence, we'll call the rate of change z. Because 40 is 3 terms away from 5, we can write 5 * z * z * z = 5z³ = 40.

z³ = 8 → z = 2

Now, we simply multiply 5 by 2 to get x, which is 10, and then we multiply x by 2 to get 10 * 2 = 20 for y. Hope this helps!

Answers

Answer:

The second one; x²+7x+12

Step-by-step explanation:

So, since the beginning lengths of the square is x and x, the area of the square is x².

But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).

Finally, you would multiply them together to get the equation you would use to find the new area.

For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
