Answer:

probability that the integer not evenly divisible by 2 is  \frac{1}{2}.

Step-by-step explanation:

Given : An integer be chosen at random from the integers 1 to 30 inclusive.

To find  : Find the probability that the integer chosen is not evenly divisible by 2.

Solution : We have integers 1 to 30.

We need to find probability that the integer not evenly divisible by 2.

We know that odd numbers are not divisible by 2

Odd number 1 to 30 ( 1 , 3, 5, 7 ,9,11,13,15,17,19,21,23,25,27,29)

Total odd number 1 to 30 =  15 .

Probability =  \frac{favourble\ outcome}{total\ numver\ of\ outcome}.

Probability = \frac{15}{30}.

Probability = \frac{1}{2}.

Therefore,  probability that the integer not evenly divisible by 2 is  \frac{1}{2}.

Exactly half of these integers are odd (1, 3, 5, ..., 29) so the probability of selecting an odd number is \dfrac12.

2/3(3y+6)=0 Please help! One solution, No solution, or Many solutions? Please answer by 3:35, September 4, 2020
Serjik [45]

Answer:

one solution

Step-by-step explanation:

2/3(3y+6)=0

Multiply by 3/2

3/2 *2/3(3y+6)=0*3/2

3y+6 = 0

Subtract 6 from each side

3y = -6

Divide by 3

3y/3  = -6/3

y = -2

There is one solution

Simplify the rational expression. State any restrictions on the variable n^4-11n^2+30/ n^4-7n^2+10
djyliett [7]
To factor both numerator and denominator in this rational expression we are going to substitute n^{2} with x; so n^{2} =x and n ^{4} =  x^{2}. This way we can rewrite the expression as follows:
\frac{n^{4}-11n^{2} +30 }{n^{2}-7n^{2} +10 } =  \frac{ x^{2} -11x+30}{ x^{2} -7x+10}
Now we have two much easier to factor expressions of the form a x^{2} +bx+c. For the numerator we need to find two numbers whose product is c (30) and its sum b (-11); those numbers are -5 and -6. (-5)(-6)=30 and -5-6=-11.
Similarly, for the denominator those numbers are -2 and -5. (-2)(-5)=10 and -2-5=-7. Now we can factor both numerator and denominator:
\frac{ x^{2} -11x+30}{ x^{2} -7x+10} = \frac{(x-6)(x-5)}{(x-2)(x-5)}
Notice that we have (x-5) in both numerator and denominator, so we can cancel those out:
\frac{x-6}{x-2}
But remember than x= n^{2}, so lets replace that to get back to our original variable:
\frac{n^{2}-6 }{n^{2}-2 }
Last but not least, the denominator of rational expression can't be zero, so the only restriction in the variable is n^{2} -2 \neq 0
n^{2}  \neq 2
n \neq +or- \sqrt{2}
