Answer:

0.5806

Step-by-step explanation:

Out of a group of 145 students that were surveyed about sports, 31 said they play basketball and 59 said they play soccer. 18 of the students who said they play basketball said they also play soccer. If a student is chosen at random, find the probability. P (Soccer |Basketball).

Solution:

P(soccer) = number of students playing soccer/ total number of students.

P(soccer) = 59/145

P(basketball) = number of students playing basketball/ total number of students.

P(basketball) = 31/145

P(soccer and basketball) = number of students playing soccer and basketball/ total number of students.

P(soccer and basketball) = 18/145

From Bayes theorem:

P(A | B) = P(A ∩ B) / P(B)

Hence:

[tex]P(soccer|basketball)=\frac{P(soccer\cap baketball)}{P(basketball)}=\frac{\frac{18}{145} }{\frac{31}{145} } =0.5806[/tex]

How to solve the addition of integers?

To add integers having the same sign, keep the same sign, and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

How to solve the subtraction of integers?

To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative. If the signs are different subtract the smaller absolute value from the larger absolute value.

Answer

Step-by-step explanation:

α - β , α + β are the zeroes of x² - 4x + 3.

The coordinates of (a,b)

(Let a = α & b = β).

On comparing with standard form of a quadratic equation i.e., ax² + bx + c = 0 ;

Let ;

a = 1

b = - 4

c = 3.

We know that,Sum of the zeroes = - b/a

⟹ α - β + α + β = - ( - 4)/1

⟹ 2α = 4

⟹ α = 4/2

⟹ α = 2

And,

Product of the zeroes = c/a

⟹ (α - β) * (α + β) = 3/1

(a + b) * (a - b) = a² - b².

⟹ α² - β² = 3

Putting the value of α we get,

⟹ (2)² - β² = 3

⟹ 4 - 3 = β²

⟹ 1 = β²

⟹ √1 = β

⟹ 1 = β

∴(a , b) = (α , β) = (2 , 1). (Option - C).

I hope it will help you.

Siso your answer refer in pic

Answer:

ST = 52

SW = 54

WV = 54

Step-by-step explanation:

Because TW is a median line, that means that SW and WV are the same length. So, SW = WV or:

2x + 30 = 5x -6

We can then rearrange to have all the x's on one side like so:

2x - 2x + 30 = 5x -2x -6

30 = 3x -6

30 + 6 = 3x -6 +6

36 = 3x

Then, we divide both sides by 3 to find x by itself:

[tex] \frac{36}{3} = \frac{3x}{3} [/tex]

12 = x

To finish, replace x with 12 in each equation:

ST = 12 + 40

ST = 52

SW = 2(12) + 30

SW = 24 + 30

SW = 54

WV = 5(12) -6

WV = 60 -6

WV = 54

Answer:

I believe it is $17.6

Step-by-step explanation:

40 x 0.4 = 16 -------> 16 x 0.1 = 1.6

add 1.6 to $16 which equals 17.6

Answer:

This is a trick answer but the answer is 24 minutes

Step-by-step explanation:

They have already added up the time and its 24 if you read 1 is 8 the second is 12 and 3 pipes are 24

Also lemme get brainlist

Answer:

4.8 min (4 min 48 seconds)

Step-by-step explanation:

In one minute:

Pipe A fills the tank 1/8th full

Pipe B fills the tank 1/12 full

Pipe C fills the tank 1/24th full

1/8 + 1/12 + 1/24 = 5/24

So the the at which they will fill the tank is 24/5,

or 4.8 minutes (4 minutes 48 seconds)

Step-by-step explanation:

Answer: (5,0)

Step-by-step explanation:

You could remove this one, because for each input (x) there can only be 1 output (y)

So by removing (5,0) this becomes a function. 5 only has one output now, (3)

Answer:

Step-by-step explanation:

Compare the equations ...

  ax² +bx +c = 0

  x² -x +6 = 0

and you can see that the values of a, b, c are ...

  a = 1, b = -1, c = 6

Putting these values into the expression for the discriminant, ...

  d = b² -4ac

we have ...

  d = (-1)² -4(1)(6) = 1 -24 = -23

The discriminant is -23.

__

The interpretation of the discriminant is ...

  negative -- 2 complex solutions

  zero -- one real solution

  positive -- 2 real solutions

Here, the discriminant is negative, so ...

The equation has 2 complex solutions.

Answer:

the answer is 1

for example, 1÷1 equals one. a number that is the same divided is always 1. another example. 2÷2 is 1.

Answer: The answer is 1

Step-by-step explanation:Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

149×914=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

14×99×14=126126

Since 126 divided by 126 equals 1 then,

126126=1

Therefore:

149÷149=1

Solution by FormulasApply the fractions formula for division, to

149÷149

and solve

14×99×14

=126126

=1

Therefore:

149÷149=1

Answer:

3 feet

Step-by-step explanation:

Lara has 2 pieces of string. One is 15 feet long and the other is 12.

We solve this question using the Greatest Common Factor method.

We have to find the factors of 12 and 15

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 15 are: 1, 3, 5, 15

Then the greatest common factor is 3.

Therefore, the greatest length, in feet, that she can make is 3 feet

Answer:

The total volume is 62.5.-

Step-by-step explanation:

Giving the following information:

The equation below shows the total volume (V), in cubic units, of 4 identical boxes with each side equal to "s" units:

V = 4*(s^3)

Now, the total volume if s=2.5:

V= 4*(2.5^3)

V= 4*15.625

V= 62.5

The total volume is 62.5.-

Answer:

30 square units

Step-by-step explanation:

4 x 2.5 units= 10.

take the 3 from the V, (4s³).

Multiply that.

4 x 2.5 square units = 10

10 x ³ = 30 square units In total.

Complete question :

The play director 190 hours preparing for a plane that time include attending 35 rehearsals that took varying amount of time in spending 93 3/4 hours on the other responsibilities related to the play. What question does the equation 3/5 x + 93 3/4 equal 190 help answer? A. How much longer did the director spend on rehearsals and on other responsibilities? B. What was the average length of each rehearsal? C. How long was each rehearsal?

Answer: C. How long was each rehearsal?

Step-by-step explanation:

Total time spent preparing for play = 790 hours

Of the 190 hours :

Number of rehearsals = 35

Others = 93 3/4 hours

What question does the equation 35 x + 93 3/4 equal 190

35x + 93 3/4 = 190

(Number of rehearsals) * x + others = total time

x = time spent on each rehearsal

35x = 190 - 93 3/4

35x = 96.25

x = 96.25 / 35

x = 2.75 hours

Each rehearsal took 2.75 hours
