An unusual number cube (with 6 sides) has the numbers 2, 2, 4, 4, 6, and 6 on its faces.
It is rolled once.
Match the outcome to its probability.
Answers
Answer:
1. P(2 or 4) - 2/3
2. P(multiple of 2) - 1
3. P(multiple of 3) - 1/3
4. P(odd prime numbers) - 0
Step-by-step explanation:
Hope this helps
P(2 or 4) = 2/3
p(multiple of 2) = 1
p(multiple of 3) = 1/3
P(odd prime numbers) = 0
What are the probabilities?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
P(2 or 4) = (number of sides that have a value of 2 / total number of sides) + (number of sides that have a value of 2 / total number of sides) = 2/6 + 2/6 = 2/3
p(multiple of 2) = number of sides that are a multiple of 2 / total number of sides
6/6 = 1
p(multiple of 3) = number of sides that are a multiple of 3/ total number of sides
= 2/6 = 1/3
P(odd prime numbers) = number of odd prime numbers / total number of sides = 0

(3+13-10)+14÷2+4 how do you solve this ?
Answers
Answer: 17
Step-by-step explanation:
Don't forget about PEMDAS. (parentheses, exponents, multiplication, division, addition, subtraction)
Start with parentheses
(3+13-10)... 13+3= 16, 16-10=6 ...
so (3+13-10)=6
Now we have...
6 + 14 / 2 + 4
No exponents so we go on.
no multiplication so we go on
Now division...
14 / 2 = 7 because 7 x 2 = 14
Now we have...
6 + 7 + 4
now we do addition, addition is commutative so you can add it in any order you want
6 + 7 = 13, 13 + 4 = 17
therefore, the answer is 17

Which scatter plot shows a negative linear association?
A.
B.
C.
D.
Answers
Answer:
D
Step-by-step explanation:
If you imagine the dots continued in a connected line, (imagining where the data points will likely go), the line's slope informs you if it is a negative (going down/negative slope) linear association or if it's a positive (going up/positive slope) linear association.
For A, it has a positive slope [as it increases].
For B, it also has a positive slope
For C, there is no correlation, the dots are not showing any trends
For D, there is a negative slope.
This means that the scatter plot D shows a negative linear association.
Option (D) shows a negative linear association between the variables is the correct answer.
A scatter plot is a type of data visualization that shows the relationship between different variables. Scatter plots are used to plot data points on a horizontal and a vertical axis in an attempt to show how much one variable is affected by another.
For the given situation,
The graph shows the data points on a horizontal and a vertical axis.
A scatter plot with an increasing value of one variable and a decreasing value for another variable can be said to have a negative correlation.
Among graphs, in option (D) when one variable tends to increase in the x-axis, the other variable decreases in the y-axis.
Hence we can conclude that option (D) shows a negative linear association between the variables is the correct answer.

Answer:
x = 25
Step-by-step explanation:
First turn this into an equation:
[tex]\frac{4}{5}[/tex] times x = 20
Now divide both sides by [tex]\frac{4}{5}[/tex]. You can't divide by a fraction, instead you multiply by flipping the fraction. So now you're multiplying both sides by [tex]\frac{5}{4}[/tex].
20 times 5 = 100. Next you divide [tex]\frac{100}{4}[/tex]. This is equal to 25. You have completed the equation and now have the answer:

Answer:
x=-2
Step-by-step explanation:
Given equation:
8^x= 1/64
Ensure both sides of the equation are in power format by changing 1/64
1/64 = 64^-1
8^x = 64^-1
2^3(x) = 2^6(-1)
The bases will cancel out each other
3(x) = 6(-1)
3x = -6
x = -6/3
x = -2

8^x = 1/64
x = -2
8^-2
