A survey of 46 college athletes found that 24 played volleyball, while 22 played basketball. a) If we pick one athlete survey participant at random, what is the probability they play basketbali? b) If we pick 2 athletes at random (without replacement), what is the probability we get one volleyball player and one basketball player?

Answer 1
Answer:

Answer:

A) (11)/(23)

B) (88)/(345)

Step-by-step explanation:

A survey of 46 college athletes found that

  • 24 played volleyball,
  • 22 played basketball.

A) If we pick one athlete survey participant at random,  the probability they play basketball is

P_1=(22)/(46)=(11)/(23)

B) If we pick 2 athletes at random (without replacement),

  • the probability we get one volleyball player is (24)/(46)=(12)/(23);
  • the probability we get another basketball player is (22)/(45) (only 45 athletes left).

Thus, the probability we get one volleyball player and one basketball player is

P_2=(12)/(23)\cdot (22)/(45)=(88)/(345)

MAJOR HELPP!!!!!!!!!!! Picture Below guyyss! oof this is hard

Answer:

93

Step-by-step explanation:

Use PEMDAS and plug in the values for x and y. So replace x with 8 in the parenthesis, resulting in (8+2x3) since you do multiplication before addition, it would be 8+6 equaling 14. 14 would be multiplied by 6, so it would be 84, but do not forget the y^2, which would be 3^2 and since 3x3 is 9, you would add 9 to 84
93 is the answer.

To find the answer, we can first put x=8 and y=3 into the equation:

y^2 + 6(x + 3×2)
=3^2 + 6(8+3×2)

We can them proceed to calculate by doing the multiplications in the first steps:

=9 + 6(8+6)
=9 + 6×14
=9 + 84
=93

Therefore, the answer is 93.

Hope it helps!

Which equation supports the given conjecture? The sum of the squares of two consecutive integers is an odd integer.

A.
(2 + 3)2

B.
32 + 52 = 34

C.
4 + 52 = 29

D.
52 + 62 = 61

Answers

the first part says the sum of the squares of two consecutive integers or in other words (x)(x)+(x+1)(x+1) so we can cross out A because 2 and 3 are prime numbers (no factors)  we can cross out all the others because the square root of 52 is not an integer so any equation with 52 in it does not satisfy the requirement. so none of them are corect.  additionally, some of the equations are obviously false such as 52+62=61

The verified answer is wrong the correct answer is d 5 squared plus 6 squared. Because the question is asking for two consecutive integers and it wants an odd integer therefor d is the correct answer because it has to squared consecutive integers and an odd answer.

Solve the quadratic equation for x. What is one of the roots? (x + 6)^2 = 49

Answers

The value of one of the roots x of the quadratic equation(x + 6)^2 = 49 is 1.

A polynomial is an expression with nonnegative coefficients and consists of constants, variables, and operators ( addition, subtraction multiplication, and division)The highest power of the polynomial is called the degree of the polynomial. The polynomial whose degree is 2 is called a quadratic polynomial.

For example; 3x^2- 5x+9=0, here the degree of the polynomial is 2, so it is a quadratic polynomial.

The roots of the equation can be calculated as:

( x+6)^2 = 49\n( x+6)^2 = (7)^2\n x+6 = 7\nx = 7-6\nx = 1

Thus, one of the roots of the equation  (x + 6)^2 = 49 is 1.

Answer:

x equals -1 and it also equals -13. They are both considered the roots.

Step-by-step

  1. (x+6)^2= 49    to get rid of the exponent square root each side of the equation.
  2. (x+6)= √49     Find square root of 49.
  3. (x+6)= ±7        It could be positive 7 or -7 because both of them squared equal 49. Now solve for each possible equation, (x+6)= 7 and  (x+6)=-7.
  4. (x+6)=7  subtract 6 from each side.
  5. x= 1
  6. (x+6)=-7  Subtract 6 from each side.
  7. x=-13
  8. So the answers are -13 and 1.
