A orange chew was selected 18 times.
A lemon chew was selected 6 times.
A peach chew was selected 25 times.
Based on these results, express the probability that the next chew Colton removes
from the bag will be orange or lemon as a decimal to the nearest hundredth.

Each morning Tess chooses either a red ribbon or a blue ribbon at random to wear in her hair. What is the probability that Tess will choose a red ribbon on both Monday and Tuesday?
Answer:
1/4 chance
Step-by-step explanation:
First you need to find the probability of Tess choosing a red ribbon.
1/2
Then you need to multiply that probability by the reciprocal of 2, which is 1/2
1/2 x 1/2 = 1/4
Where is the error in the solution below? Explain what the error is and solve the equation correctly. Be sure to check your answer.
Answer:
The error in the question is that in the second line, both sides are not multiplied by x. This causes an imbalance in the equation.
Step-by-step explanation:
[tex]\frac{5}{x}= x-4[/tex]
Multiply both sides by x.
[tex]x(\frac{5}{x}) = x(x-4)[/tex]
[tex]5= x^{2} -4x[/tex]
Subtract 5 from the equations.
[tex]x^{2} -4x-5=0[/tex]
Factorise the equation (Quadratics)
[tex](x-5)(x+1)=0[/tex]
Null Factor Law
[tex]x=5[/tex] or [tex]x=-1[/tex]
Here, we have to go through the equation and correct it:
Starting equation: 5/x = x - 4
Multiply both sides by x:
x * (5/x) = x * (x - 4)
[tex]5 = x^2 - 4x[/tex]
Move all terms to one side to set up a quadratic equation:
[tex]x^2 - 4x - 5 = 0[/tex]
Now, we have a quadratic equation that needs to be solved.
We can solve this quadratic equation using factoring, completing the square, or the quadratic formula.
In this case, let's use factoring:
(x - 5)(x + 1) = 0
This gives you two possible solutions:
x - 5 = 0 --> x = 5
x + 1 = 0 --> x = -1
So, the correct solutions for the equation 5/x = x - 4 are x = 5 and x = -1. The error in your solution was in the step where you multiplied by x; you didn't distribute x properly to both terms on the right side of the equation.
This causes an imbalance in the equation.

The profitability, P, of a popular restaurant franchise can be modeled by the function P (t) = t4 – 9t3 + 24t2 – 20t, where t is the number of months since the restaurant opened. How many months after the franchise opens will it begin to show a profit?
5 months
3 months
2 months
1 month
Replace t with the months given as choices to see which one gives a positive value as an answer.
P(1) = 1^4-9(1)^3 + 24(1)^2-20(1) = -4
P(2) = 2^4-9(2)^3+24(2)^2-20(2) = 0
P(3) = 3^4 -9(3)^3+24(3)^2-20(3) = -6
P(5) = 5^4-9(5)^3+24(5)^2-20(5) = 0
P(6) = 6^4-9(6)^3+24(6)^2-20(6) = 96
It shows a profit in month 6 so it would start showing a profit in month 5.
The answer is 5 months

9x - 2 = 8x + 6 (opposite angles on the transversal)
9x - 8x = 6+2
x = 8
18.
-5 + 21x + 15x +5 = 180 (angles on the same side of transversal add up to 180)
36x = 180
x = 180/36
x = 5
19.
9x + 4 + 95 = 180 (angles on the same side of transversal add up to 180)
9x + 99 = 180
9x = 180-99
9x = 81
x = 81/9
x = 9
20.
16x - 2 = 110 (opposite angles on the transversal)
16x = 110 +2
16x = 112
x = 112/16
x = 7
21.
29x + 4 = 31x -4 (opposite angles on the transversal)
4 + 4 = 31x - 29x
2x = 8
x = 8/2
x= 4
22.
12x + 2 + 6x + 16 = 180(angles on the same side of transversal add up to 180)

R/4=36/R
A)8
B)9
C)12
D) 20
The value of R is 12.
What are square roots?A value that yields the original number when multiplied by itself is known as the square root of a number. The square root is a backwards technique for figuring out a number. Thus, squares and square roots are connected ideas.
Given R/4 = 36/R
multiply both sides by R
R/4 x R = 36/R x R
R²/4 = 36
multiply both sides by 4
R²/4 x 4 = 36 x 4
R² = 144
so R = √144
R = 12
Hence R = 12 for given condition.

Answer:
g(x) = (x -3)² -6
Step-by-step explanation:
You know that a function f(x) is translated h units to the right when x is replaced by x-h.
g(x) = f(x-h) . . . . . translated h units right
You also know that a function f(x) is translated k units up when k is added to the function value.
g(x) = f(x) +k . . . . . translated k units up
__
Here, we want to translate f(x) 3 units right and 6 units down. Using the above relations, we will get ...
g(x) = f(x -3) -6
Using the given definition of f(x), this becomes ...
g(x) = (x -3)² -6
