10. Harmony places the letters in the word DECEMBER into a bag. A letter will be randomly
selected and not replaced. Then another letter will be selected. What is the probability of
Hormony selecting a C and then an E?
Answer:
3/56
Step-by-step explanation:
There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to [tex]\frac{1}{8}[/tex] times [tex]\frac{3}{7}[/tex], which is equal to [tex]\frac{3}{56}[/tex].

find the 29th term of the arithmetic sequence 182,176,170
9514 1404 393
Answer:
14
Step-by-step explanation:
The first term of the sequence is 182, and the common difference is 176-182=-6. So, the general term is ...
an = a1 +d(n -1)
an = 182 -6(n -1)
The 29th term will be ...
a29 = 182 -6(29 -1)
a29 = 14

F(x) = 3 x 2 − 3 x − 6 The domain of a the function f(x) is { -10, -1, 1, 5 }. What is the range of the relation?
Answer:
{324, 0, -6, 54}
Step-by-step explanation:
Given that F(x) = 3x² − 3 x − 6 If the domain of a the function f(x) is { -10, -1, 1, 5 }.
To get the range, we will find f(x) for all the domains
at x = -10
f(-10) = 3(-10)²-3(-10) - 6
f(-10) = 3(100)-3(-10) - 6
f(-10) = 300+30-6
f(-10) = 330-6
f(-10) = 324
at x = -1
f(-1) = 3(-1)²-3(-1) - 6
f(-1) = 3(1)-3(-1) - 6
f(-1) = 3+3-6
f(-1) = 6-6
f(-1) = 0
at x = 1
f(1) = 3(1)²-3(1) - 6
f(1) = 3(1)-3(1) - 6
f(1) = 3-3-6
f(1) = 0-6
f(1) = -6
at x = 5
f(5) = 3(5)²-3(5) - 6
f(5) = 3(25)-3(5) - 6
f(5) = 75-15-6
f(5) = 60-6
f(5) = 54
Hence the range of the relation are {324, 0, -6, 54}

Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:
x=5
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−12=−4x+23
Step 1: Add 4x to both sides.
3x−12+4x=−4x+23+4x
7x−12=23
Step 2: Add 12 to both sides.
7x−12+12=23+12
7x=35
Step 3: Divide both sides by 7.
7x

the perimeter of a rectangle is 52 cm. The length of the rectangle can be represented by (x.+5) and its width can be represented by (3x-7) what are the dimensions of this rectangle?
Answer:
Length=11
Width=11
Step-by-step explanation:
P (perimeter) is 52 so
2(x+5)+2(3x-7)=52
then
2x+10+6x-14=52
8x-4=52
8x=48
x=6

what is the measure of each interior angle of a regular 12-gon?
Answer:
Once you know the sum, you can divide that by 12 to get the measure of each interior angle: 1800°/12 = 150°
Step-by-step explanation:
Answer:
150°

t = total riders
s = number of bus-stops
If it picked up 9 bus-stops, to find the total number of riders, substitute s = 9 into the equation.
Thus:
t = 5(9)
t = 45

For what value of x is the given parallelogram a
rhombus?
(6x +13)
(9x-5)
The given parallelogram is a rhombus when x=
Answer:
x = 6
Step-by-step explanation:
(9x - 5)° = (6x +13)°
9x - 5 = 6x + 13
9x - 6x = 13 + 5
3x = 18
x = 18/3
x = 6
The given parallelogram is a rhombus when x = 6
The value of 'x' for which the parallelogram will be a rhombus is x = 3.
What is a rhombus?A quadrilateral with all equal sides is a rhombus.
Rhombuses are a particular kind of parallelogram in which all of the sides are equal since the opposite sides of a parallelogram are equal.
A rhombus has 360° of interior angles total.
A rhombus's adjacent angles add up to 180°.
A rhombus's diagonals are perpendicular to one another and cut each other in half.
One more property of rhombus is that the diagonals bisect the originating angles.
Therefore, The values of 'x' for which this parallelogram will be a rhombus is, 6x + 13 = 9x - 5.
6x - 9x = - 5 - 13.
- 3x = - 18.
3x = 18.
x = 6.
