Mattie uses the discriminant to determine the number of zeros the q

Mathematics
1 answer:
enot [183]3 years ago
3 0

Answer:for ax^2+bx+c=0 the discriminant is b^2-4ac

there are 3 basic cases of what happens for different discriminants

1. if the discriminant is less than 0, then there are no real zeroes

2. if the discriminant is 0, then it has 1 zero

3. if the discriminant is greater than 0, it has 2 zeroes

so given

0=3x^2-7x+4

a=3,b=-7,c=4

thus the discriminant is (-7)^2-4(3)(4)=49-48=1

the discriminant is 1. 1 is positive, thus the equation has 2 zeroes because the discriminant is greater than 0

the answer is the equation has two zeroes because the discriminant is greater than 0

If a die is rolled one time, find probability of getting a number greater than 3 and an odd number.
Nadya [2.5K]

Answer:

\dfrac{1}{6}.

Step-by-step explanation:

It is given that a die is rolled one time. So,

Sample space : S=\{1,2,3,4,5,6\}

Number is greater than 3 : A=\{4,5,6\}

Number is odd : A=\{1,3,5\}

Number greater than 3 and an odd number : A\cap B=\{5\}

It is conclude that,

n(S)=6, n(A)=3,n(B)=3,n(A\cap B)=1

The probability of getting a number greater than 3 and an odd number is

P=\dfrac{n(A\cap B)}{n(S)}

P=\dfrac{1}{6}

Therefore, the required probability is \dfrac{1}{6}.

Use the information given to correctly complete the sentence.
IRISSAK [1]

Explanation: 54 yards is about 162 feet, and since we are converting measurements we need this ( duh ) and 135 seconds is approximately 2.25 minutes, so what we need to do is is divide the numbers like any conversion problem: 162 divided by 2.25  is 72.

Hope this answer helps!

What is the value of y in this triangle?
yarga [219]

Answer:

26 degrees.

Step-by-step explanation:

The angles of triangles will always add up to 180 degrees.

The first angle is 50 degrees.

The second angle, is shown with a 76 degree angle next to it.

Since this is a 180 degree line, we can find the angle of the bottom right corner by doing 180 - 76. 180 - 76 is 104.

104 + 50 = 154 degrees.

The remaining 26 degrees is the answer to the value of y.
