Answer:
12/27
Step-by-step explanation:
You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Let the total number of marbles = 6 red marble + 3 blue marbles = 9 marbles
You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Assume all you picked is red( without replacement)
= 6/9 × 5/9
= 30/81
= 10/27
Assume all you picked is blue( without replacement)
= 3/9 × 2/9
= 6/81
= 2/27
The probability of the events is calculated as:
All red or All blue
= 10/27 + 2/27
= 12/27
The equation of a parabola with vertex at (-2, 2) and passes through (-3, 5) and (-1, 5) is y = 3x² + 12x + 14. The value of a in the equation is 3.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The graph of a quadratic equation has the shape of a parabola. The standard quadratic equation has the form:
y = ax² + bx + c
The equation of a parabola with vertex at (-2, 2) and passes through (-3, 5) and (-1, 5) is y = 3x² + 12x + 14. The value of a in the equation is 3.

Answer:
<h2><u><em>
5 inch</em></u></h2>
Step-by-step explanation:
Two legs of a right triangle measure 3 inches and 4 inches. Which of the following choice for the length of the third side will make the triangle a right triangle?
- not having the choices we solve with Pythagoras
x = √(3²+4²)
x = √(9 + 16)
x = √25
<h2><u><em>
x = 5</em></u></h2>
Answer:
16
Step-by-step explanation:
5+15-8/4=
5+15-4=
16
3 consecutive even integers.....x, x + 2, and x + 4
1/2(x + 2 + x + 4) = 65....multiply both sides by 2, canceling out 1/2
x + 2 + x + 4 = 65 * 2
2x + 6 = 130
2x = 130 - 6
2x = 124
x = 124/2
x = 62
x + 2 = 62 + 2 = 64
x + 4 = 62 + 4 = 66
so ur numbers are : 62,64,66 <==
