There are 10 blue marbles, 4 red marbles and 8 yellow marbles in a bag. John draws three marbles without replacement. What is the probability the first two marbles are yellow and the third is red?
Answer:
3/12
Step-by-step explanation:
There are 22 marbles in all so the probability would be
3/22 but we are looking at specific colors so add the red and yellow marbles together and you should get 3/12
What is the product of 5 and 8 square root 200 in the simplest radical form
[tex]\sqrt{2}[/tex]Answer:
400[tex]\sqrt{2}[/tex]
Step-by-step explanation:
5 * 8[tex]\sqrt{200}[/tex]
[tex]\sqrt{200}[/tex] = [tex]\sqrt{100 * 2}[/tex] = [tex]\sqrt{100}[/tex] * [tex]\sqrt{2}[/tex] = 10[tex]\sqrt{2}[/tex]
5*8(10[tex]\sqrt{2}[/tex]) = 400[tex]\sqrt{2}[/tex]
Jan has three dimes In her pocket and nothing else. she takes one coin out of her pocket. what is the probability that the coin Jan takes out is a dime ?
The probability that the coin Jan takes out is a dime would be 100% or 3/3
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that Jan has three dimes In her pocket and nothing else. she takes one coin out of her pocket.
Picking with replacement, twice from 3 dimes.
Probability of picking a dime each time = 3/3
Which is 100 percent because there is nothing els.

Step-by-step explanation:
x^2 + 4x – 7 = 0
Pls n thx
Answer:
x = - 2 ± [tex]\sqrt{11}[/tex]
Step-by-step explanation:
To solve the equation using the method of completing the square.
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
add ( half the coefficient of the x- term )² to both sides
x² + 2(2) x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{11}[/tex] ← exact solution

The angle measurements in the diagram are represented by the following expressions.
\qquad \blueD{\angle A=6x + 5^\circ}∠A=6x+5
∘
start color #11accd, angle, A, equals, 6, x, plus, 5, degrees, end color #11accd \qquad\green{\angle B=4x + 45^\circ}∠B=4x+45
∘
start color #28ae7b, angle, B, equals, 4, x, plus, 45, degrees, end color #28ae7b
Answer:
x = 20, ∠ A = 125°
Step-by-step explanation:
∠ A and ∠ B are Alternate interior angles and are congruent, so
∠ A = ∠B , substitute values
6x + 5 = 4x + 45 ( subtract 4x from both sides )
2x + 5 = 45 ( subtract 5 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20
Thus
∠ A = 6x + 5 = 6(20) + 5 = 120 + 5 = 125°
Answer:
∠A = 125 degrees.

Here is an inequality: -3x >18.
a. List 3 values for x that would make this
inequality true.
b. How are the solutions to the inequality -3x
>18 different from the solutions to -3x >18?
Explain your reasoning
Answer:
a. -7, -8, -10
b. In -3x≥18, the solution set includes -6 (which gives -18) because -18 is equal to -18, which is allowed. In -3x>18, -6 is not allowed since -18 cannot equal -18.

[tex]y = 4x - 9[/tex]
>/\<
Answer:
y=4x+(-9)
Step-by-step explanation:
Slope intercept form is y=mx+b
m is the slope which can be found using rise/run. In this case 4/1=4 so m=4
b is the y intercept which is the y value where the line passes through the X axis. This also can be found as the Y value where X=0 if that is easier for you. In this problem y=-9 where X=0. Therefore b=-9.
Plug these values back into the equation and you get the equation of the line in slope intercept form. For this line that is y=4x+(-9).

The equation [tex]x^3-x^2+ax+b=0[/tex] has three integer solutions.
Two of these solutions are [tex]x=1[/tex] and [tex]x=2[/tex].
Work out the third solution to the equation.
Answer:
x = - 2
Step-by-step explanation:
x³-x²+ax+b = (x-1)(x-2)(x+c) = x³ + (c-3)x² + (2-3c)x +2c
c-3 = -1 C = 2
a = 2 - 3c = 2 - 3*2 = - 4
b = 2c = 4
third solution: x+2=0 x=-2
