How many months of the year have 31 days? Jan, Mar, May, Jul, Aug, Oct, Dec. That's 7 months out of 12. Thus, if you were to pick a month from these 12, the chances that you'd pick one that had 31 days would be 7/12, or approx. 0.58.

There are 12 months, 7/12 have 31 days. You would have a 7/12 probability of choosing one with 31 days if it is random.

First step for solving this quadratic equation? <br> x2+2x-11=4

kenny6666 [7]

Answer:

subtract 4 from both sides

Step-by-step explanation:

Given

x² + 2x - 11 = 4

First step : subtract 4 from both sides

x² + 2x - 15 = 0 ← in standard form

Second step : factorise the quadratic

(x + 5)(x - 3) = 0 ← in factored form

Third step : equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 3 = 0 ⇒ x = 3

Fourth step : state the solutions

solutions are x = - 5, x = 3

4 1/4 divided by 3 and 1/2

kenny6666 [7]

Answer:

1 3/14

Step-by-step explanation:

1. You want to turn the fractions into mixed numbers.

2. 4 1/4 is equal to 17/4

3. 3 1/2 is equal to 7/2

4. I have a fraction calculator and got 1 and 6/28.

5. To solve it yourself, flip 7/2 to make it 2/7 and change from division to multiplication.

Looked like: $\frac{17}{4}$ ÷ $\frac{7}{2}$

Looks like: $\frac{17}{4}$ · $\frac{2}{7}$

17 times 2 is 34 and 4 times 7 is 28. Leaving us with 34/28.

Now just simplify and get an answer of 1 and 3/14.

Which is a perfect square?

Leni [432]

Answer:

I believe it's 6^2.

Step-by-step explanation: 6^2 is the same as 6 times 6. Here's a tip, if you see a 2 as an exponent, you can also say x squared. X to the power of 2 is the same as x squared.
