Jackson has a bag that contains 5 blue socks, 7 pink socks, and 8 yellow socks.
Jackson removes a single sock from the bag 50 times. Each time he records the color of the sock that is drawn. He replaces the socks into the bag before the next draw.
How many blue socks would be expected to be drawn if 1000 pulls are conducted? 10,000 pulls?
Answer:
for 50 pulls, 12.5 blue socks, but you cant have half of a sock so we say 12
for 1000 pulls, 250 blue socks
for 10,000 pulls, 2500 blue socks
Step-by-step explanation:
First we add 5, 7 and 8 to find the total number of socks, 5+7=12 and 12+8 = 20
5 is the amount of blue socks, so
5/20 * how many pulls are conducted is the probability for blue socks
7 is the amount of pink socks, so
7/20 * how many pulls are conducted is the probability for pink socks
and
8 is the amount of yellow socks, so
8/20 * how many pulls are conducted is the probability for yellow socks

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

Which of the following arcs are congruent in the circle below
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
Sin <A = 4/5

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)

Now that you know the height of the cone how can you solve for the slant height?
Answer:
imagine a triangle
one side is just upwards trough the cone, one side is the radius of the circle and the last one is the slant height.
remember the pythagoras stuff
so
(slantheight)² = radius² + height²
or finally:
slantheight = squareroot (radius² + height²)
The graph of an absolute value function = a|x| includes the point (1,6). Complete the following statements. The value of a is ____
Answer:
6
Step-by-step explanation:
y = f(x)
6 = a |1 |
6 = a. 1
a = 6/1
a = 6
Answer:
[tex] \displaystyle a = 6[/tex]
Step-by-step explanation:
we are given a absolute value function
[tex] \displaystyle f(x) = a |x| [/tex]
we want to figure out the value of a
since we are a point which is on the function we can figure out a by using the point i.e (1,6) this point tell us when x is 1 f(x) is 6 thus
substitute:
[tex] \displaystyle 6= a \cdot |1| [/tex]
absolute value of any integer is positive therefore,
[tex] \displaystyle 6= a \cdot 1[/tex]
simplify multiplication:
[tex] \displaystyle 6= a [/tex]
hence,
the value of a is [tex]\underline{\quad 6 \quad}[/tex]

Parallelogram T U V S is shown. Angle U is (4 x + 9) degrees and angle V is (6 x minus 29) degrees.
Which angles equal 91°?
angles T and V
angles S and U
angles U and V
angles S and T
==========================================================
Explanation:
Angles U and V are adjacent angles since they are right next to each other in the letter sequence TUVS.
When dealing with parallelograms, adjacent angles are always supplementary (meaning they add to 180).
U+V = 180
(4x+9) + (6x-29) = 180
10x-20 = 180
10x = 180+20
10x = 200
x = 200/10
x = 20
Use this x value to find each angle mentioned
angle U = 4x+9 = 4*20+9 = 89 degreesangle V = 6x-29 = 6*20-29 = 91 degreesWe can see that U+V = 89+91 = 180 which helps confirm our answer so far.
Angle V is part of the answer we want. The angle opposite this is angle T.
We can identify a pair of opposite angles by looking at letters where they are separated by some other letter between them.
Opposite angles in a parallelogram are always the same measure. Both angles T and V are 91 degrees.
That means angles U and S are each 89 degrees.
Answer:
The answer is A- angles T and V

can someone help me identify c(6)=
Answer and Step-by-step explanation:
To solve, simply plug 6 in for m in the equation.
C(6) = 50(6) + 79.50
6 times 50 is 300.
300 + 79.50 = 379.50 = C(6)
The answer is 379.5
(Looking at the question again, I don't think what I said is what it is asking for, soo)
The slope of the function given represents the amount that needs to be paid every month. The y-intercept (79.50) represents the initial cost (starting amount) for paying the membership.
