If two balanced die are rolled, the possible outcomes can be represented as follows. (1, 1) (2, 1) (3, 1) (4, 1) (5, 1) (6, 1) (1, 2) (2, 2) (3, 2) (4, 2) (5, 2) (6, 2) (1, 3) (2, 3) (3, 3) (4, 3) (5, 3) (6, 3) (1, 4) (2, 4) (3, 4) (4, 4) (5, 4) (6, 4) (1, 5) (2, 5) (3, 5) (4, 5) (5, 5) (6, 5) (1, 6) (2, 6) (3, 6) (4, 6) (5, 6) (6, 6) Determine the probability that the sum of the dice is 11.
Answer:
1/18Step-by-step explanation:
A die is known to have 6 faces. If n die are rolled, the total number of outcomes or sample space is expressed as;
n(S) = [tex]6^n[/tex] where;
n is the total number of dies
If two balanced die are rolled, the total number of sample space will be;
n(S) = [tex]6^2 = 36[/tex]
Since we want to to determine the probability that the sum of the dice is 11, the possible outcome or event will be;
n(E) = {(5, 6), (6,5)}
N(E) = 2
Probability = Possible outcome/Total outcome
Probability that the sum of the dice is 11 = n(E)/n(S)
Probability that the sum of the dice is 11 = 2/36
Probability that the sum of the dice is 11 = 1/18
Calendars are on sale for 13 off the regular price. What is the sale price of a calendar with a regular price of $14.55?
Answer:
I don't know if my answer is correct but I would say $12.65
Step-by-step explanation:
The reason I would say this is because 13 percent off 14.55 is 1.8915 and I rounded that to 1.89 and subtracted that from 14.44 to get $12.65

Work out the percentage change to 2 decimal places when a price of £11 is decreased to £8.
Answer:
= 27.2727% decrease
Step-by-step explanation:
The percentage change to 2 decimal places when a price of £11 is decreased to £8 is 27.27%
How to find how much percent 'a' is of 'b'?Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
Given that:
A price is decreased from 11 euros to 8 euros.We've to find the percent changePercent change shows how much percent of the initial amount is changed.
Since we're taking about 'change', so it doesn't matter whether this was a positive change or a negative change.
Percent change = Percent that "absolute difference of 11 and 8" is of "inital price 11"
Absolute difference of 11 and 8 = [tex]|11 - 8| =3[/tex] (in euros)
Initial price is 11 euros.
Then, we get:
Percent change in price = the percent which 3 is of 11.
Let 3 is x% of 11, then we get:
[tex]x = \dfrac{3}{11} \times 100 = 27.27\overline{27}\approx 27.27[/tex]
Thus, percent change in considered price for this case is approximately 27.27%

What is Average Rate of Change of a Function?Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.
Given a table which shows how far a distance runner has traveled since the race began.
If f(x) is a function, the average rate of change of the function in the interval [a, b] is,
f(b) - f(a) / b - a
Here the interval is (0.75, 1).
Average rate of change of the function is,
Average rate of change = (4.75 - 3.50) / (1 - 0.75)
= 1.25 / 0.25
= 5
Hence the required average rate of change is 5 miles per hour.

You are conducting a left-tailed test of a claim about a population mean when sigma is unknown with a sample size of 7.
If
α
=
.005
, find the critical value, to two decimal places.
========================================================
Explanation:
You'll need to use a T table to answer this question. Your stats textbook should have such a table in the back appendix section.
If your textbook doesn't have the proper table, or you don't have your textbook with you, then I recommend searching online for "t table" and you should have tons of free options to choose from.
In the table you'll look for the degrees of freedom row 6, since the degrees of freedom are equal to n-1. In this case, n = 7.
In this row, locate the column labeled "alpha = 0.005" and you'll be looking at "one tail". The value in this row and column is roughly 3.707
Since we're doing a left tailed test and we want P(t < C) = 0.005, where C is the critical value we're after. This must mean C < 0. So C = -3.707 approximately. Round this to two decimal places and we end up with -3.71
