edgar rolls two six-sided number cubes. What is the probability that he rolls a 5 on the first cube and a number greater than 4
on the second cube? Use the diagram 1of the sample space to help you.
1 answer:
Answer:D
Step-by-step explanation:
The diagram can be thrown out the window. All we need is to find the chance of a 5, then the chance that the second cube rolls a 5 or a 6.
The cube has 6 possible numbers. The number 5 is one of them. Therefore we have a 1/6 chance of rolling a 5.
The second cube has 6 possible numbers. Two of those are what we want. Therefore we have a 2/6 chance, or rather 1/3 chance of rolling a 5 or 6.
Combining these, we have a 1/6 chance to roll a 5, and on top of that we have a 1/3 chance to roll a number we want.
and that is our final answer.

For this case we have a function of the form:
Where,
A: initial amount
b: growth rate (for b> 1)
x: independent variable
y: dependent variable
We then have the following function:
Using the definition, the following statements are correct:
1) The function is exponential
2) The function increases by a factor of 2.5 for each unit increase in x
3) The domain of the function is all real numbers

Given:
The value of the solid's surface area is equal to the value of the solid's volume.
Length(l) = 9 units
width(b) = 4 units
Height(h) = x units
To find:
The value of x.
Solution:
Solid's surface area is
Volume of solid is
Solid's surface area = Volume of solid
Divide both sides by 10.
Therefore, the value of x is 7.2.
