If you were to roll the dice one time what is the probability it will NOT land on a 2? Put your answer in fraction form.
Answer:
5/6
Step-by-step explanation:
On a standard 6-sided die, there is only one 2. That means that there are 5 other numbers that it could land on (1, 3, 4, 5, 6).
Using that information, the probability of it not landing on a 2 is 5 out of 6 or 5/6. This is because you must do part over whole. The "part" in this situation is the 5 "wanted" numbers, and the "whole" is 6 because there are six potential numbers that it could land on.
I hope this helps.
The probability that it will not land on a 2 is 5/6
Probability is the likelihood or chance that an event will occur.
It will land on 2, Prob (land on 2) = 1/6
It will not land on 2, the probability will be given as:
Prob (not land on a 2) = 1 - 1/6
Prob (not land on a 2) = 5/6
Hence the probability that it will not land on a 2 is 5/6

Answer:
D.) The expected value is 1.78
Step-by-step explanation:
The expected value of a probability distribution is evaluated using the formula.
Expected Value, [tex]E(X)=\sum^{n}_{i=1}x_iP(x_i)[/tex]
Therefore, from the given probability distribution, we have:
E(X)=(0*0.3)+(1*0.2)+(2*0.16)+(3*0.2)+(4*0.04)+(5*0.1)
E(X)=1.78
The Expected value of X is 1.78.

3p + q = 8 and
3p - q = 10
then p+q is?
Answer:
2
Step-by-step explanation:
3p + q = 8 and
3p - q = 10
then p+q is?
--------
add up side-by-side:
6p=18 ⇒ p=3
q=8-3p= 8 - 9= -1
p+q= 3-1=2
Answer:
2
Step-by-step explanation:
3p + q = 8
3p - q = 10
→ Minus the two equations away from each other which would cancel out 3p
2q = -2
→ Divide both sides by 2 to isolate q
q = -1
→ Substitute q = -1 back into 3p + q = 8
3p - 1 = 8
→ Add 1 to both sides to isolate p
3p = 9
→ Divide both sides by 3 to isolate p
p = 3
⇒ The question asks us to find p + q so,
3 + - 1
→ Remember the minus cancels out the plus

Complete the following frame for 6x = 54:
The equation is true when x = _ because _.
Answer:
The equation is true when x = 4 because 6(4) = 24 that is x=4 satisfies the given equation.
Step-by-step explanation:
Given: [tex]6x=24[/tex]
To find: x
Solution:
A equation is a statement that defines the equality of two expressions or numbers.
[tex]6x=24[/tex]
Divides both sides by 6
[tex]\frac{6x}{6}=\frac{24}{6}\\x=4[/tex]

please help with slope question fast
Answer:
C
Step-by-step explanation:
this is because perpendicular lines have the opposite reciprocal slopes. So, 3/2 is the opposite reciprocal of -2/3 since it is negative and that is the opposite sign. Then, it is the reciprocal of the fraction since the numerator and the denominator are switched. If you check the other answer options, you will see that none of the slopes are the exact opposite reciprocal.

Jose is blocking off several rooms in a hotel for guests coming to his wedding. The hotel can reserve small rooms that can hold 3 people, and large rooms that can hold 4 people. Jose reserved twice as many small rooms as large rooms, which altogether can accommodate 70 guests. Write a system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved. Define the variables that you use to write the system.
Answer:
No. of large rooms = 7
No. of small rooms = 14
Set of equations
4x + 3y = 70
y = 2x
Variable definitions
No. of large rooms is x
No. of small rooms is y
Step-by-step explanation:
capacity of large rooms = 4 people
let the no. of large rooms be x
thus, total no of people which can be accommodated in x rooms = 4*x = 4x
capacity of small rooms = 3 people
let the no. of small rooms be y
thus, total no of people which can be accommodated in y rooms = 3*y = 3y
total no. of people which can be accommodated in x large room and y small room will be = 4x + 3y
It is given that total small room and large room can accommodate 70 guests
thus,
4x + 3y = 70 _________equation 1
_________________
It is also given that Jose reserved twice as many small rooms as large rooms,
so, if no. of large rooms is x and no. of small rooms is y
then
y = 2x _________equation 2
substituting value of y in equation 1 we have
4x + 3(2x) = 70
=>4x + 6x = 70
=> 10x = 70
=> x = 70/10 = 7
No. of large rooms = 7
No. of small rooms = y= 2x = 2*7 = 14
Set of equations
4x + 3y = 70
y = 2x
Variable definitions
No. of large rooms is x
No. of small rooms is y
The number of the small rooms is 14.
The number of large rooms is 7.
Assuming that the number of the large rooms is x,
So, the number of small rooms is 2x
According to the question:
[tex]3[/tex] × [tex]2x[/tex] [tex]+ 4[/tex] × [tex]x = 70[/tex]
[tex]6x+4x=70\\10x=70\\x=7[/tex]
So, 2x = 2(7) = 14
Therefore, the number of the small rooms is 14 and the number of large rooms is 7.

7. Simplify the following equation:
9x-7i > 3 (3x-7u)
Answer:
i<3u
Step-by-step explanation:
Let's solve for i.
9x−7i>3(3x−7u)
Step 1: Add -9x to both sides.
−7i+9x+−9x>−21u+9x+−9x
−7i>−21u
Step 2: Divide both sides by -7.
−7i
−7
>
−21u
−7
i<3u
Hope this helps.
Answer: i < 3u
We first distribute 3.
9x-7i > 3 (3x-7u)
9x-7i > 9x - 21u
Subtract 9x from both sides.
-7i > -21u.
Divide both sides by -7. Since -7 is negative so the inequality sign will change.
i < 3u.

Let Brandon's age be b. We can write 4b = b + 27 which gives us b = 9. Because Michael is 4 times as old as Brandon, he is 9 * 4 = 36 years old.
Answer:
36
Step-by-step explanation:
Micheal is 4 times as old as Brandon.
y = 4x
Micheal is also 27 years older than Brandon.
y = x +27
Y represents Micheal's age, and x represents Brandon's age.
Since both equations above are equal to the same value, y, you can set the two equations equal to each other. Solve for x.
4x = x + 27
3x = 27
x = 9
Brandon is 9 years old.
Plug Brandon's age into one of the equation to solve for Micheal's age.
y = x + 27
y = 9 + 27
y = 36
Micheal is 36 years old.

Find the volume of a triangular prism that has a triangular base of4 and height of3 with a prism height of 11
Answer:
66 cubic units
Step-by-step explanation:
For a prism, the volume is the area of the base multiplied by the height.
area of base = area of triangle = (1/2) * base * height (of the base)
volume = area of base * height of prism
volume = (1/2) * 4 * 3 * 11
volume = 66

At the end of a snow storm, Mason saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 0.5 inches per hour. Write an equation for the function S(t), representing the depth of snow on Mason's lawn, in inches, t hours after the snow stopped falling.
Answer:
S(t) = 10 - 0.5t
Step-by-step explanation:
initial depth of snow = 10 inches
melting rate = 0.5 inches per hour
it means that, in one hour snow depth will decrease by 0.5 inches
thus , in t hours snow depth will decrease by 0.5*t = 0.5t inches
Thus, depth of snow after t hours can be calculated by
we will take initial depth of snow and them subtract the depth of snow which melted in t hours.
we are subtracting as snow is melting and will thus decrease the depth of snow
depth of snow after t hours can = initial depth of snow - decrease of the depth of snow after snow melts for t hours
depth of snow after t hours can = 10 inches - 0.5t inches
= (10 - 0.5t )inches
Thus ,S(t), representing the depth of snow on Mason's lawn, in inches, t hours after the snow stopped falling is S(t) = 10 - 0.5t
