What is the probability of rolling a 3 on a six-sided cube AND rolling a 6 on a six-sided cube?
ob
Answer:
The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30
Step-by-step explanation:
These are independent events.
The probability of rolling a 5 is 1/6.
The probability of spinning a 5 is 1/5.
The probability of rolling a 5 or spinning a 5 is 1/5+1/6=11/30 but you have to subtract 1/30 because you can roll a 5 and spin a 5 at the same time. Therefore 11/30-1/30=10/30=1/3.
There are 30 outcomes. Roll first then spin to get the following outcomes:
11,12,13,14,15,21,22,23,24,25,31,32,33,34,35,41,42,43,44,45,51,52,53,54,55,61,62,63,64,65
You want to roll a 5 OR spin a 5. How many combinations have a 5 ? 10 combinations have a 5.
(you don't count 55 twice) There are 10 combinations with a 5 out of a possible 30 combinations.
Another way of looking at the problem is the following:What is the probability of NOT rolling a 5 AND NOT spinning a 5 ?
The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30. Therefore the probability of rolling a 5 or spinning a 5 is 1-20/30=10/30.
Answer:
16.7%
Step-by-step explanation:
There are 6 sides and one three on the cube so rolling a three would be 1/6. To roll a 6 on a 6 sized dice would be the same there’s 6 sides and one 6 so it would be 1/6

The function d=16t^2 models the distance d, in feet, that an object falls in t seconds. Find the inverse function and use the inverse function to estimate the time it takes an object to fall 100 feet.
Answer:
Step-by-step explanation:
d = 16t^2
t^2 = d/16
t = 0.25√d
When d = 100 ft, t = 2.5 seconds

4.2x-1.4y= 2.1 what is Y plz i need help and i don't understand
Answer:
y = -1.5 + 3x
Step-by-step explanation
I'm sorry but I have no time, can someone comment me and explain? Thank you :)
Answer: y = -1.4(2.1 - 4.2x)
Step-by-step explanation:
4.2x - 1.4y = 2.1
Firstly you should move 4.2x over (by subtraction) so the new equation is:
-1.4y = 2.1 - 4.2x
Then you want to multiply everything by -1.4 to take it away from the y side. This will bring you to:
y = -1.4(2.1 - 4.2x)
This can be simplified down to
y = -2.94 + 5.88x
or
5.88x -2.94 = y
x + y = 5
y = 3x + 1
How do I find the solution from these two equations by graphing
Answer:
x=1, y=4
Step-by-step explanation:
x+y=5 - (1)
y=3x + 1 (2)
Sub (2) into (1)
x + (3x +1)=5
4x=5-1
x=4 ÷4
=1
Sub x=1 into (2)
y=3(1)+1
= 4

The variables x and y are proportional. Use the values to find the constant of proportionality. Then write an equation that relates x and y.
When y=72 and x=3.
K = ?
y = ?
Answer:
k = 24, y = 24x
Step-by-step explanation:
Given x and y are proportional then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = 72, x = 3 , then
72 = 3k ( divide both sides by 3 )
k = 24
y = 24x ← equation of proportion

HELP
Step-by-step explanation:
move the shape 1 square to the left and then move it one square up
The triangle after a translation 1 unit to the left and 1 unit up will have vertices at (2, 2), (-4, 4), and (-2, 0).
Translation is a rigid transformation that moves each point of a figure a certain distance in a specified direction. For this triangle, we will translate all its vertices 1 unit to the left and 1 unit up.
Impact on the Coordinates:
Let's consider each vertex of the triangle and apply the translation:
a) Vertex (3, 1):
After the translation, this point will move 1 unit to the left and 1 unit up. Therefore, the new coordinates will be (3 - 1, 1 + 1) = (2, 2).
b) Vertex (-3, 3):
This point will also move 1 unit to the left and 1 unit up. The updated coordinates will be (-3 - 1, 3 + 1) = (-4, 4).
c) Vertex (-1, -1):
Similarly, this point will undergo the translation, resulting in (-1 - 1, -1 + 1) = (-2, 0).
New Triangle:
Now, we have the new coordinates for the vertices after the translation:
Vertex 1: (2, 2)
Vertex 2: (-4, 4)
Vertex 3: (-2, 0)
The transformed triangle will have vertices at (2, 2), (-4, 4), and (-2, 0).

. Liliana is renting a beach house for a family vacation. The house charges a $75 cleaning fee plus $95 per night. If Liliana wants to spend a maximum of $645 on the rental, which inequality represents “n”, the number of nights can she afford to rent the beach house?
Answer:
6 nights
Step-by-step explanation:
Set up your equation:
645=95n+75
then subtract the cleaning fee from the total to remove it from both sides
570=95n
then divid the remaining budget by the $95 per night charge
570/95= n =6
Meaning that she can afford 6 nights in the beach house at that price
The table below shows data from a survey about the amount of time high school student spent reading in amount of time spent watching videos each week (without reading). Which response best describes outliers in the data sets?
A. neither data set has suspected outliers
B. The range of data is too small to identify outliers
C. video has a suspected outlier in the 26-hour value
D. due to the narrow range of reading compared to video the video values of 18, 21, and 26 are all possible outliers
Answer:D
Step-by-step explanation:
Neither data set has suspected outliers response best describes outliers in the data sets.
Option A is correct.
What is IQR?The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
According to question
Reading:
Median = [tex]\frac{7+12}{2}[/tex] = 9.5
[tex]Q_{1}[/tex] = 5 × 25% + 7 × 75% = 6.5
[tex]Q_{3}[/tex] = 14 × 25% + 12 × 75% = 12.5
IQR is the difference between Q3 and Q1
IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 12.5 - 6.5 = 6
[tex]Q_{1}[/tex] - 1.5 IQR = 6.5 - 1.5 × 6 = -2.5 < Min = 5
[tex]Q_{3}[/tex] + 1.5 IQR = 6.5 + 1.5 × 6 = 15.5 > Max = 15
So no outlier in reading
Video :
[tex]Q_{1}[/tex] = 7 × 75% + 4 × 25% = 6.25
[tex]Q_{3}[/tex] = 21 × 25% + 18 × 75% = 18.75
IQR is the difference between Q3 and Q1.
IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 18.75 - 6.25 = 12.5
[tex]Q_{1}[/tex] - 1.5 IQR = 6.25 - 1.5 × 12.5 = -12.5 < Min = 1
[tex]Q_{3}[/tex] + 1.5 IQR = 18.75 + 1.5 × 12.5 = 37.5 > Max = 26
So no outlier in video
So neither data set has suspected outliers.
Option A is correct.

Answer: a=101 b=79 c=83 d=97
Step-by-step explanation:
A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.
B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.
C: opposite angles are always the same so it would still be 83°.
D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.
