A six-sided number cube is rolled twice the expression 1/6 x 1/6 can be used to find P(5, then3). The correct option is D.
What is probability?Probability is a measure of how likely an event is to occur. Many events are impossible to predict with absolute certainty.
The probability of rolling a 5 and then a 3 is independent, so we can find the probability by multiplying the probability of rolling a 5 on the first roll by the probability of rolling a 3 on the second roll.
The probability of rolling a 5 on the first roll is 1/6, and the probability of rolling a 3 on the second roll is also 1/6.
Therefore, the expression that can be used to find P(5, then 3) is: B. 1/6 * 1/6

Zack is creating a 5 digit password for his computer. For the first three digits, he chooses different letters of the alphabet.
For the last two digits, he chooses a different number
between 0-9. How many passwords are possible?
Answer:
460
Step-by-step explanation:
The total number of passwords possible is given by the permutation equation A = 26 x 25 x 24 x 10 x 9
What are Permutations?A permutation is an ordered arrangement.
The number of ordered arrangements of r objects taken from n unlike objects is:
Permutation nPr = ( n )! / ( n - r )!
Given data ,
Let the total number of passwords be represented as A
Now , the equation will be
The number of digits in the password = 5 digits
For the first three digits, he chooses different letters of the alphabet
So , total number of digits that are alphabets out of the 26 alphabets = 3
For the last two digits, he chooses a different number
between 0-9
The total number of digits that are numbers out of the 10 numbers = 2
So , the permutation will be
A = 26P3 x 10P2
Substituting the values in the equation , we get
The total number of passwords A = ( 26 )! / ( 26 - 3 )! x ( 10 )! / ( 10 - 2 )!
On simplifying the equation , we get
The total number of passwords A = ( 26 )! / ( 23 )! x ( 10 )! / ( 8 )!
And ,
The total number of passwords A = 26 x 25 x 24 x 10 x 9
Therefore , the value of A is 14,04,000
Hence , the permutation is 26P3 x 10P2

The cost of laying wood floors consists of a base price of $250, plus $3.50 for each square foot installed. Define the variable
Let s = the base price of laying wood floors
Let s = the cost of each square foot
Let S = each square foot of wood installed
Let s = $250
Answer:
Let s = each square foot of wood installed
Step-by-step explanation:
Total cost of laying wood = base price + price for each square foot installed
Base price = $250
Price for each square foot installed = $3.50
Let
s = number of each square foot installed
Total cost of laying wood = $250 + $3.50s
The correct answer is
Let s = each square foot of wood installed
Can you describe the pattern of the number of dots as a function of the Picture number? Tell how you got your
answer.
Answer:
In order to describe the pattern of the number of dots as a function of the picture number you have to take the average values of each number and find the line of best fit between each dot. This gives you a function, such as, f(x) = mx+b.
A line is represented by the equation y = 3x - 7. Which of the following statements about the line is TRUE?
A. The y-intercept is 7.
B. The "rise over run" is equivalent to
1/3
.
C. The point (1, 4) lies on the line.
D. The line has a positive slope
Answer: The "rise over run" is equivalent to 1/3
Step-by-step explanation:
Since the m variable in the equation is 3, the line is going to be wider, there for it will go up 1 and 3 to the right with each point on the line, therefore the answer is B.
The requried slope of the line is 3, which is a positive number. Therefore, the line has a positive slope, and option D is true.
What is the equation?The equation is the relationship between variables and represented as y = ax + b.
Here,
A.
The y-intercept is -7.
The equation y = 3x - 7 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Therefore, the y-intercept of this line is -7, not 7, as given in option A.
B.
The "rise over run" is equivalent to 3. Option B is not correct.
C.
point (1, 4) lies on the line.
To check whether the point (1, 4) lies on the line, we can substitute x = 1 and y = 4 into the equation y = 3x - 7 and see if the equation is true:
y = 3x - 7
4 = 3(1) - 7
4 = -4
Since the equation is not true, the point (1, 4) does not lie on the line, and option C is false.
D.
The line has a positive slope.
As we determined earlier, the slope of the line is 3, which is a positive number. Therefore, the line has a positive slope, and option D is true.

A store has fifteen 2 liter bottles of soda on the shelf. How many milliliters of soda does the store have?
Answer:
30,000 milliliters
Step-by-step explanation:
There are 15 2-liter bottles, so you must get the total number of liters by multiplying 15 and 2 to get 30. Then, because there are 1,000 milliliters per liter, you multiply 30 by 1,000 to get 30,000 milliliters total.
Graph the line.
x = 3
Explanation: I would do this problem by setting up a chart.
For the equation x = 3, if we set up a chart for x and y,
since x must be equal to 3, the random values we
choose in this problem are not for x, they are for y.
If we had an equation like y = 2x + 3, then we would pick values for x
and plug them into the equation to get y, but here, x is our only value.
So let's choose the values 1, 0, and -1 for y.
For each of these values, x must be equal to 3.
So we have the points (3, 1), (3,0), and (3, -1).
Notice that our graph is a vertical line, as I showed this below.

At Zach's auto shop each mechanic can change the oil 3 cars per hour. Zach can have up to 4 mechanics working at a time. In a relationship between number of oil changes per hour and number of mechanics working identify the independent variable dependent variable domain and range
Answer:
We know that:
Each mechanic can change the oil of 3 cars per hour.
The number of mechanics can change between 0 and a maximum of 4.
Then we can write the variable:
Y = number of oil changes per hour.
Y = 3*X
Where X is the number of mechanics working.
The independent variable is X (number of mechanics), because is the one that Zach can change, and the dependent is Y (number of oil changes) because this depends on the value of X.
Now, the domain will be: {0, 1, 2, 3, 4}
The possible numbers of mechanics working at the same time.
And for the range we must replace those values in our equation, and see the possible values of Y.
Y(0) = 3*0 = 0
Y(1) = 3*1 = 3
Y(2) = 3*2 = 6
Y(3) = 3*3 = 9
Y(4) = 3*4 = 12
Then the range is: {0, 3, 6, 9, 12}
