3/10 is the Probability of not Drawing Blue Marbles
Step-by-step explanation:
Blue Marbles = 7
Green Marbles = 2
Red Marbles = 1
Total Marbles = 7 + 2 + 1 = 10
Probaility of Drawing Blue Marbles = 7 /10
Probability of not Drawing Blue Marbles = 1 - Probaility of Drawing Blue Marbles
= 1 - 7/10
= 3/10
or
Probability of not Drawing Blue Marbles = Probability of drawing Green or Red Marbles
= 2/10 + 1/10
= 3/10
3/10 is the Probability of not Drawing Blue Marbles
Answer:
The standard error of the sample mean is 0.57
Step-by-step explanation:
we know that
The Standard Error Formula is given by the formula

where:
SE = standard error
s = standard deviation
n = the sample size
In this problem we have

substitute in the formula


Answer:
$184.72
Step-by-step explanation:
$71.70/3 = $23.09
$23.09*8=$184.72
-10, I believe that is the answer.
Remark
The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?
Solution
36 * (x/100) = 29.52 Multiply both sides by 100
36 * x = 29.52 * 100 The 100 on the left disappears.
36 * x = 2952 The decimal disappears. Divide by 36
x = 2952/36
x = 82%
That is not your answer. That just tells you what % of 36 is that would give 29.52
Answer
The % discount is 100 - 82 = 18%. That is the % discount.
