Answer:
6 times
step-by-step explanation:
cubes have 6 faces, 3 of those being even and 2 of those being even and over 2
that gives a chance of 2/6 or 1/3
if he rolls it 18 times multiply the chances
1/3 • 18/1
18/3
6
Answer:
y=3x-4
Step-by-step explanation:
Complete question :
A random sample of n = 83 measurements is drawn from a binomial population with probability of success 0.4 . Complete parts a through d below. a. Give the mean and standard deviation of the sampling distribution of the sample proportion, . The mean of the sampling distribution of is nothing. The standard deviation of the sampling distribution of is nothing.
Answer:
Mean = 33.2000
Standard deviation = 4.4632
Step-by-step explanation:
Given that :
Sample size (n) = 83
Probability of success (p) = 0.4
q = p' = (1 - p) = 1 - 0.4 = 0.6
The mean of the sampling distribution :
Sample size * probability of success
n * p = 83 * 0.4 = 33.2000
The standard deviation of the sampling distribution :
σ=√(sample size * probability of success * (1 - p))
σ = √n * p * (1 - p)
σ = √(83 * 0.4 * 0.6)
σ = √19.92
σ = 4.46318
σ = 4.4632

Answer:
<em>x</em><em> </em><em>=</em><em> </em><em>6</em>
Step-by-step explanation:
<em>To</em><em> </em><em>attain the</em><em> </em><em>x-intercepts</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>to</em><em> </em><em>let</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>0</em><em>.</em>
<em>So</em><em> </em><em>in</em><em> </em><em>this</em><em> </em><em>case you will be</em><em> </em><em>having</em><em>:</em>
<em>4</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>(</em><em>0</em><em>)</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em>
<em>4</em><em>x</em><em>/</em><em>4</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em><em>/</em><em>4</em>
<em>x</em><em> </em><em>=</em><em> </em><em>6</em>
<em>Hopefully</em><em> </em><em>it</em><em> </em><em>makes sense</em><em>.</em>
