Answer:
[tex]P(4) = \frac{1}{6}[/tex]
[tex]P(\text{not a 2}) = \frac{5}{6}[/tex]
[tex]P(\text{3 or 5}) = \frac{1}{3}[/tex]
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Number cube:
A number cube is a dice, which has six sides, numbered 1 to 6.
P(4)
One the sides is a 4, thus:
[tex]P(4) = \frac{1}{6}[/tex]
P(not a 2)
Of the 6 sides, one is a 2, and the other 5 are not 2. So
[tex]P(\text{not a 2}) = \frac{5}{6}[/tex]
P(3 or 5)
One sides is 3, other is 5, 1 + 1 = 2. So
[tex]P(\text{3 or 5}) = \frac{2}{6} = \frac{1}{3}[/tex]

3(h+6) = 2(-5-2h) Solve for h
Answer:
h = -4
Step-by-step explanation:
3(h+6) = 2(-5-2h) Solve for h.
Apply distributive property first on both sides.
3(h+6) = 2(-5-2h)
3h+18 = -10-4h
Next, put the terms with h on one side and the numbers on the other.
3h+18 = -10-4h
7h = -28
Divide both sides by 7 and you have your answer.
7h = -28
h=-4
Answer:
-4
Step-by-step explanation:
First, expand the brackets by multiplying the left bracket all by 3 and the right all by 2. This gives 3h+18=-10-4h.
You want h all on one side, so add 4h to both sides, leaving 7h+18=-10.
Subtract 18 on both sides to leave only h and the coefficient on the left. This gives 7h=-28.
Dividing both sides by 7 isolates the x and gives h=-4.

a right triangle has legs of lengths 6 and 2, what is the length of the hypotenuse to the nearest tenth
Answer:
6.3
Step-by-step explanation:
[tex]6^{2} + 2^{2} = x^{2}[/tex]
40 = [tex]x^{2}[/tex]
[tex]\sqrt{40} = \sqrt{x^{2} }[/tex]
x = 6.3
Answer:
6.3
Step-by-step explanation:
Pythagoras' Theorem (or Pythagorean Theorem) states a²+b²=c², where c is the hypotenuse.
We can use this equation and swap a and b for 6 and 2. This gives 6²+2²=c², which can be expanded to 36+4=c², and further c²=40.
To work out c, we need to square root both sides, leaving c=6.3245553203367586639977870888654, which rounded to 1 decimal place (nearest tenth) is 6.3.

What is the measure of the reference angle for a -289 angle
A. 89
B. 71
C. 289
D. 19
Answer:
B
Step-by-step explanation:
The reference angle and the given angle are the same angle.
Add 360° to the given angle , so
reference angle = - 289° + 360° = 71° → B

Answer:
(a) -12
(b) 37
(c) -840
Step-by-step explanation:
We simply have to plug in the values for each expression.
2 + -3(3) - 5 = 2 + -9 - 5 = -7 - 5 = -12
5(2) - 4(-3) + 3(5) = 10 - -12 + 15 = 10 + 12 + 15 = 22 + 15 = 37
7(2^3)(-3)(5) = 7(8)(-15) = 56(-15) = -840
Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode, she drove at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85 meters away from the safe zone. Let D(t) denote the distance to the safe zone D (measured in meters) as a function of time t (measured in seconds).
Which of the below formulas is the correct function's formula?
A. D(t) = -25t + 160
B. D(t) = 25t + 160
C. D(t) = -25t - 160
D. D(t) = 25t - 160
Step-by-step explanation:
A. D(t) = -25t + 160
this is the correct answer because if you substitute 3 you get 85
A cylinder has a volume of 200 cubic centimeters. If the height of the cylinder is 10 centimeters, what is the radius of the cylinder?
Answer:
The radius of the cylinder is 2.52 cm.
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and height h is
V = πr²h. We can solve this for r² by dividing both sides of the equation by πh:
r² = V / (πh)
Then the desired radius is found by taking the square root of this.
r = √{V / [πh]}
200 cm^2
Here, r² = ------------------- = 6.37 cm^2
3.14(10 cm)
and so r = √6.37 cm^2 = 2.52 cm
The radius of the cylinder is 2.52 cm.
Answer:
radius = 2.52 cm
Step-by-step explanation:
[tex]Volume = \pi r^2 h\\\\200 = \pi r^2 \times 10\\\\\frac{200}{10 \times \pi} = r^2 \\\\6.332 = r^2 \\\\\sqrt{6.332} = r \\\\r = 2.52 \ cm[/tex]

Solve for f: efg - h = i
Given:
The equation is:
[tex]efg-h=i[/tex]
To find:
The value of f.
Solution:
We have,
[tex]efg-h=i[/tex]
We need to isolate f to find the value of f.
Adding h on both sides, we get
[tex]efg-h+h=i+h[/tex]
[tex]efg=i+h[/tex]
Dividing both sides by [tex]eg[/tex], we get
[tex]\dfrac{efg}{eg}=\dfrac{i+h}{eg}[/tex]
[tex]f=\dfrac{i+h}{eg}[/tex]
Therefore, the value of f is [tex]f=\dfrac{i+h}{eg}[/tex].

Chang wants to rent a boat and spend at most $44. the boat cost $8 per hour, and chang has a discount coupon for $4 off. what are the possible numbers of hours chain could rent the boat? Use "t" for number of hours .
Answer:
6 hours.
Step-by-step explanation:
Here's my work.
Chang only wanted to spend $44, and the boat costs $8/hr. So, the variable would only be 8t, and you would put 44 on the other side.
Then, you'd put -4 on the side with 8t, because you can take off $4.
So, the setup would be;
44 = 8t - 4.

Range is the set of y-values that are outputted by function f(x)Interval Notation - [Brackets] denote inclusion and (Parenthesis) denote exclusionStep-by-step explanation:
According to the graph, our y-values span from -1 to 6. Since -1 is a closed dot, it is inclusive. Since 6 is an open dot, it is exclusive:
Range would then be [-1, 6).
