Answer:
22.2%
Step-by-step explanation:
Probability is the chance of an event happening, it can be found by using the following formula,
Where the word (desired) represents the outcomes one wants, and (total) represents the total number of outcomes.
In this case, one is asked to find the probability of the sum of two numbers the results from rolling two dice, not being a multiple of (3) or (2). In this case, it is easier to list out the number of numbers between (1) and (12) that are not a multiple of three or two. Please note, the largest sum of number one can get when rolling two dice is (12), since the largest value on a dice is (6), and (6+6) equals (12).
Not multiples of (3) or (2):
1, 5, 7, 11
There are (4) numbers that are not multiples of (2) or (3). This means that there are (8) multiples of (2) or (3) between the numbers of (1) and (12), since (12 - 4 = 8)
The total number of outcomes is the following:
This is because there are (6) sides on a die, the number of outcomes is equal to (6) times (6), thus (
) or (
).
Now set up the probability equation:
Substituted,
Write as a decimal:
0.222
As a percent:
22.2%
Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The sample proportion is 
The margin of error is 
Given that the confidence level is 95% the level of significance is mathematically represented as
Next we obtain the critical value of 
from the normal distribution table , the values is
The reason we are obtaining critical value of instead of 
is because
represents the area under the normal curve where the confidence level interval ( 
) did not cover which include both the left and right tail while
is just the area of one tail which what we required to calculate the margin of error
Generally the margin of error is mathematically represented as
substituting values
=>
Answer:
0
Step-by-step explanation:
All lines that are parallel to y=−2 have the same slope of 0 .
''Decreased'' means subtract and ''times'' means multiplication so the algebraic expression should be 15 - 2 * p.
6 : 10 = 3 : 5
24 : 40 = 3 : 5
36 : 60 = 3 : 5
42 : 70 = 3 : 5
A. 18 : 20 = 9 : 10 (incorrect)
B. 30 : 20 = 3 : 2 (incorrect)
C. 18 : 30 = 3 : 5 (correct)
D. 50 : 30 = 5 : 3 (incorrect)
The answer is C. 18 : 30
Hope this helps. - M
