It is Marcie's first turn to roll. Which ratio shows the theoretical probability that she will not land on a star space? 1/6 1/3 1/2 2/3
Answer:
[tex]P(Not\ Star) =\frac{2}{3}[/tex]
Step-by-step explanation:
Given
See attachment
Required
Theoretical probability that a roll will not land on a star
From the attachment, we have:
[tex]n = 12[/tex] --- Total space
[tex]Star = 4[/tex]
So, the theoretical probability that a roll will land on a star is:
[tex]P(Star) = \frac{n(Star)}{n}[/tex]
[tex]P(Star) = \frac{4}{12}[/tex]
[tex]P(Star) = \frac{1}{3}[/tex]
Using the complement rule, the probability that it will not land on a star is:
[tex]P(Not\ Star) = 1 - P(Star)[/tex]
[tex]P(Not\ Star) = 1 - \frac{1}{3}[/tex]
Take LCM
[tex]P(Not\ Star) =\frac{3-1}{3}[/tex]
[tex]P(Not\ Star) =\frac{2}{3}[/tex]

What is the degree of 12x^4 -8x+ 4x^2 - 3?
Answer:
4
Step-by-step explanation:
In this problem, we are asked to determine the degree of the given expression 12X4 - 8X + 4X2 -3.

3m + 2n + 4;
m = 2 and N =4
D2 + 9k; d = 10 and k =9
3m + 4y x 2 m = 7, y = 10
Answer:
1. 18
2. 181
3. 101
Step-by-step explanation:
They want you to take each equation, and replace the letter with the number they give you after the equation.
3m + 2n + 4; m = 2, n = 4
This becomes
3(2) + 2(4) + 4
We multiply before we add, according to the order of operations. So next, the equation becomes:
6 + 8 + 4
= 18
———-
D^2 + 9k ; D = 10, k = 9
Numbers squared are numbers multiplied by themselves.
(10)(10) + 9(9)
= 100 + 81 = 181
——————-
3m + 4y x 2 ; m = 7, y = 10
3(7) + 4(10) x 2
21 + 40 x 2
Remember, multiplication always comes before addition.
21 + 80 = 101
Please let me know if you have questions on this.

Step-by-step explanation:
Three paintings are shaped like an 8-foot square a 7-foot by 4-foot rectangle and a triangle with 6-foot base and height of 7 feet. If those paintings are hung together on the outside of the building how much of the building s wall they cover together ?
Answer:
113 square feet
Step-by-step explanation:
the total area covered can be determined by adding the area of the rectangle, triangle and square together
Area of a square = length² = 8² = 64 ft²
Area of a rectangle = length x width = 7 x 4 = 28 ft²
Area of a triangle = 1/2 x base x height = 1/2 x 6 x 7 = 21 ft²
64 + 28 + 21 = 113 ft²

Step-by-step explanation:
Given the expressions

Substitute 2 into 1
[tex]x = \frac{5}{9(\frac{5}{5a-2} )+5} \\x = \frac{5}{(\frac{45}{5a-2} )+5} \\x = \frac{5}{\frac{45+5(5a-2)}{5a-2} } \\x= \frac{5}{\frac{35+25a}{5a-2} }\\x = \frac{5(5a-2)} {35+25a}\\x = \frac{5(5a-2)} {5(7+5a})\\\\x = \frac{5a-2} {7+5a}\\[/tex]

Find 3[g(4)] if g(x) = -2x + 10
Answer:
6
Step-by-step explanation:
= 3[-2(4) + 10]
= 3(-8 + 10)
= 3(2)
The function is given as g(x) = -2x + 10 then the solution of the 3[g(4)] would be equal to 6.
What is a function?A function is a type of relation, or rule, that maps one input to a specific single output.
Functions that are formed by composing two or more functions in a way that one's output is another's input are called composite functions.
They are also called functions of functions.
We have to find 3[g(4)] if g(x) = -2x + 10
3[g(4)] = 3[-2(4) + 10]
3[g(4)] = 3(-8 + 10)
3[g(4)] = 3(2)
3[g(4)] = 6

Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to
Applying the Pythagorean theorem, we have ΔPQR ≅ ΔABC. then we would have: ∠ACB = ∠PRQ = 90°
What is the Pythagroean Theorem?The pythagorean theorem states that the square of the longest side (hypotenuse) of a right triangle is always equal to the sum of the squares of the other two sides (legs) of the right triangle.
Since we know that ΔPQR is a right triangle, then:
x² + y² = PQ²
We are also given that x² + y² = z², so by substitution, we have:
z² = PQ², which makes both triangles have corresponding congruent sides. Therefore, ΔPQR ≅ ΔABC.
Using the corresponding parts of the congruent triangles, we can conclude that: ∠ACB = ∠PRQ = 90°.

Answer:
B. s = 9 inches
Step-by-step explanation:
We are given a square with a perimeter of 36 inches, along with a key that the perimeter is given through the equation P = 4s, where "s" stands for the length of one side. We are then asked to find which number s is.
Perimeter is when you add 4 sides altogether, in our case we have 36 inches as our perimeter. Since 4s is the main factor as to how we got 36 inches, we need to set up one system equation.
P = 4s
36 = 4s
Now we need to find a number that multiplies with 4 to get us 36, simple as that. Let's get s alone to retrieve our answer :
36 = 4s
Divide 4 from both sides :
9 = s
s = 9

I WILL MARK BRAINLIEST! A parabola opening up or down has vertex (0,3) and passes through (4,7). Write its equation in vertex form.
Ok...so we have this........
y = ax2 + 4 ....... and we need to find "a"
So we have
-1 = a(-10)2 + 4
-5 = a (100)
(-1/20) = a ....... So we have ..........
y = (-1/20)(x- 0)2 + 4 or just (-1/20)x2 + 4
Note that this parabola opens downward...That makes sense since the vertex is above the x axis and the parabola passes through a point below the x axis.
Hope This Helped!
