A box contains 5 blue, 4 red, and 3 yellow marbles. Two marbles are randomly drawn and not replaced. What is the probability of drawing a blue then a red marble?
5/36
20/130
1/66
5/33
Answer:
the answer is 5/33
Step-by-step explanation:
Total marbles = 5 blue + 4 red + 3 yellow = 12
Two marbles are selected, first is blue which gives us :
5/12 --eq 1
Then red marble is selected ( note: one marble is already drawn and not replaced so we have a total of 11 marbles )
The probability of red gave us :
4/11 --eq 2
Now we multiply eq 1 and 2
5/12 x 4/11 = 5/33

Solve for x. Enter the solutions from least to greatest. 3x^2 – 33x + 54 = 0
lesser x =? greater x=?
Answer:
Step-by-step explanation:
3x² - 33x + 54 = 0
Divide the whole equation by 3
x²- 11x + 18 = 0
Sum = -11
Product = 18
Factors = -9 , -2 { - 9 + (-2) = -11 ; (-9) *(-2) = 18}
x² - 2x - 9x + -9 * -2 = 0
x(x - 2) - 9(x - 2) = 0
(x-2)(x-9) = 0
x - 2 = 0 ; x - 9 = 0
x = 2 ;x = 9
Lesser x = 2
greater x = 9
Answer:
lesser x = 2
greater x = 9
Step-by-step explanation:
3x² - 33x + 54 = 0
Divide both side of the equation by 3
x² - 11 x + 18 = 0
x² - 2x - 9x + 18 = 0
x ( x - 2 ) - 9 ( x - 2 ) = 0
( x - 9 ) ( x - 2) = 0
x - 2= 0 ; x - 9 = 0
solve for x
x = 2 ; x = 9
lesser x = 2
greater x = 9

Express Cos K as a fraction in the simplest terms.
The correct value of Cos K is 5/23
Step-by-step explanation:
In a right angle triangle, there are 3 side
1. Hypothenus (this is the longest)
2. Adjacent
3. Opposite
However, we can only determine the adjacent and opposite if an angle is marked in the triangle.
Now, we shall determine the value of Cos K. This can be obtaineasobtain as followed:
From the question given above, the following data were obtained:
Hypothenus = 23
Adjacent = 5
Cos K =? C
The value of Cos K can be obtained by using the cosine ratio as as illustrated below:
[tex]Cos K =\frac{Adjacent}{Hypothenus}\\\\Cos K = \frac{5}{23}[/tex]
Therefore, the value of Cos K is 5/23

Use abc to find the trigonometric ratios. Enter your answer as fractions
Answer:
Tan <A = 4/3
Cos <A = 3/5
Sin <A = 4/5
Step-by-step explanation:
From the diagram given
Hypotenuse AB = 10
Adjacent = 6
Opposite = 8 (side facingc<A)
According to SOH CAH TOA
Tan <A = Opposite/adjacent
Tan <A = BC/AC
Tan <A = 8/6
Tan <A = 4/3
For Cos <A;
Cos <A = adj/hyp
Cos <A = 6/10
Cos <A = 3/5
For sin<A:
Sin <A = opp/hyp
Sin <A = 8/10

Question 4 of 12
Write a point-slope equation for the line that passes through the point (1, 22)
and is parallel to the line given by y = 14x-3. Do not use parenthesis on the y
side.
Answer:
y - 22 = 14(x - 1)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 14x - 3 ← is in slope- intercept form
with slope m = 14
Parallel lines have equal slopes
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 14 and (a, b) = (1, 22) , then
y - 22 = 14(x - 1)

Answer:
64.05 in
Step-by-step explanation:
Lateral surface area of a cylinder = 2πrh
π= 3.14
r = radius = 9
h = height
