Bryce has 10 bals in a bag, each having a distinct color. He randomly picks a ball from the bag 4 times, with replacement. The expected number of distinct colors among the 4 balls Bryce picks can be expressed as a simplified fraction p q . Find p q.
Answer:
p = 1 ; q = 10,000
Step-by-step explanation:
Number of distinct colored balls = 10
Number of balls picked with replacement = 4
Probability = (number of required outcome / number of total possible outcomes)
Distinct picks :
P(1st) = 1 /10
P(2nd) = 1/10
P(3rd) = 1/10
P(4th) = 1/10
Expected Numbe of distinct color:
P(1st) * P(2nd) * P(3rd) * P(4th)
1/10 * 1/10 * 1/10 * 1/10
= 1/10000
p/q = 1/ 10000
p = 1 ; q = 10,000
Explain why the solution of 5x – 3 > 14.5 or 5 x minus 3 greater than 14.5 or StartFraction 2 x plus 5 over 3 EndFraction less than 4. < 4 has a solution of all real numbers, with one exception.
Answer:
There is no point where x = 3.5
Step-by-step explanation:
Given the inequality
5x – 3 > 14.5
We are to find the range of all values of x
Add 3 to both sides of the equation;
5x - 3 + 3 > 14.5+ 3
5x > 17.5
x > 17.5/5
x > 3.5
Also for the inequality;
[tex]\frac{2x+5}{3} <4\\[/tex]
Cross multiply;
[tex]2x+5 < 3(4)\\2x + 5 < 12\\[/tex]
Subtract from both sides;
[tex]2x + 5-5 < 12-5\\2x < 7\\x<7/2\\x<3.5[/tex]
The solution to both inequalities are x > 3.5 and x < 3.5. Since there is no point where x = 3.5, hence the solution will have solution on all real numbers except at x = 3.5
Answer:
When solving the first inequality, you get x > 3.5. When solving the second inequality, you get x < 3.5. The solution of an "or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.

A curve has equation y = 2xy+ 5 and a line has equation 2x + 5y = 1.
The curve and the line intersect at the points A and B. Find the coordinates of the midpoint
of the line AB
Answer:
mid point of AB (0.5 , 0)
Step-by-step explanation:
2x + 5y = 1 2x = 1 - 5y
y = 2xy+ 5 = (1 - 5y)*y + 5 = y - 5y² + 5
y-y = y - 5y² + 5 - y = - 5y² + 5
0 = - 5y² + 5
5y² = 5
y² = 1
y = 1 or y = -1
if y = 1 x = 1/2 (1 - 5) = -2 .... point A (-2 , 1)
if y = -1 x = 1/2 (1 + 5) = 3 ..... point B (3 , -1)
mid point of AB (x' , y') : x' = 1/2 (x₁ + x₂) = 1/2 (-2 + 3) = 1/2
y' = 1/2 (y₁ + y₂) = 1/2 (-1 + 1) = 0

Step-by-step explanation:
H(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}h(n)=−91⋅(− 7 1 ) n−1 h, left parenthesis, n, right parenthesis, equals, minus, 91, dot, left parenthesis, minus, start fraction, 1, divided by, 7, end fraction, right parenthesis, start superscript, n, minus, 1, end superscript Complete the recursive formula of h(n)h(n)h, left parenthesis, n, right parenthesis.
Given:
[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]
To find:
The recursive formula.
Solution:
We have,
[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]
It is in the form of explicate formula of a GP, .i.e., [tex]a_n=ar^{n-1}[/tex].
Here, [tex]a=-91[/tex] and [tex]r=-\dfrac{1}{7}[/tex].
The recursive formula of a GP is
[tex]a_n=a_{n-1}\times r[/tex]
Using this the recursive formula for given problem is
[tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex]
Therefore, the required recursive formula is [tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex].

-27
12 (67– 12) or 315 – ) < 24
Step-by-step explanation:
The given inequality is :
[tex]-27\ge \dfrac{1}{2}(6x-12)[/tex]
Solving RHS of the inequality:
[tex]-27\ge \dfrac{1}{2}\times 2(3x-6)\\\\-27\ge (3x-6)[/tex]
Adding 6 both sides of the inequality
[tex]-27+6\ge (3x-6)+6\\\\-21\ge 3x\\\\x\le -7[/tex]
The attached figure shows the graph for the given inequality.
A right triangle, JKL, is given with KJL = 30° and JKL = 90°. KM is drawn such that L, K, and M are collinear. points J and M are joined by JM with JM = JL. Find JML and explain your answer.
A- 30°
B-90°
C-180°
D-60°
Answer:
I tried but soory I can't understand
Answer:
D-60°
Step-by-step explanation:
K,L,M is collinear and JM=JL
M can only be extend to the left of K, otherwise it will overlap with L
JM = JL ΔJML is isosceles triangle ∠JML ≅ ∠JLM
∠JLM = 90 - ∠KJL = 90 - 30 = 60
∠JML = 60°

Find the inverse of f(x)=1/2x Write your answer in terms of g(x).
Answer:
The inverse of f is
[tex]g(x) = 2x[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\frac{1}{2}x[/tex]
A function g is the inverse of function f if for y = f(x), x = g(y)
[tex]y=\frac{1}{2}x[/tex]
Replace x with y
[tex]x=\frac{1}{2}y[/tex]
Solve for y
[tex]y = 2x[/tex]
Therefore, the inverse of f is
[tex]g(x) = 2x[/tex]

A virtual reality headset lists for $719. Find the net cost after trade discounts if the series discount is 10/30.
Answer:
479.33
Step-by-step explanation:
10/30 is the same as 1/3 or 33.34%.
Multiply the fraction to the original price then subtract.
719 * 1/3 = 239.67
719 - 239.67 = 479.33

The areas of two rectangles can be represented by the functions shown. Which function represents the difference in the areas, h(x) = f(x) – g(x)? h(x) = 4x2 – 4x – 11 h(x) = 4x2 – 4x + 11 h(x) = –4x2 + 4x + 11 h(x) = 4x2 – 4x – 9
Answer:
x ^2 + 5xStep-by-step explanation:
Let the area of the two triangles be expressed as;
f(x)= 4x^2+6x
g(x)=3x^2-x
Taking the difference
h(x) = f(x) - g(x)
h(x) = 4x ^2+6x - 3x^2-x
Collect like terms'
h(x) = 4x ^2 - 3x^2+6x-x
h(x) = x ^2 + 5x
Hence the difference is x^2 + 5x
Note that the functions were assumed. The same methos can be applied to any other given functions.
Answer:
B: h(x) = 4x2 – 4x + 11
